Challenges in STEM

That presentation especially prepared by STE.education for Hong Kong delegation, which visited Tallinn in October 2019 with aim to get know about STEM Education & Digital Society development of Estonia. The visit was organized by Association of I.T. Leaders in Education (AiTLE) from Hong Kong and EDB. Presentation describes the modern educational approach and today’s challenges.

Learning science in immersive virtual reality

“We believe VR/AR technology has the potential to be a standard tool in education and could revolutionise the way in which students are taught for both the K-12 segment (pre-college) and higher education.”

Dave Dolan Veative VR Learn director of product management

How immersive Virtual Realty is changing Education:

  1. RETENTION
  2. ENGAGEMENT
  3. DISTRACTION FREE

Research suggests that visualisation and a VR environment strengthen the connection between a student and a concept, possibly heightening retention. It is about participating in the learning process, having actual/virtual experiences, and enjoying the process in a self-paced, self-directed environment. When students are inside a virtual environment, they are far less prone to distractions such as other students, phones, and so on. This promotes focused attention on core concepts. Built-in learner feedback and tracked assessment ensure that learners stay on task.

VR CONTENT LIBRARY

VEATIVE VR Library has 650+ Interactive modules. It gives learning interaction: in Physics, Chemistry, Biology, Mathematics, Geography, Language Learning. Every module consists of: a learning objective, attention to a core concept, and assessments within the learning environment. Explore Veative Library here. Overview of Content is in a video below.

PHYSICS

Physics is an extremely important subject, which allows us to connect with the physical world. Its inherent complexity can be intimidating, as students can easily doubt whether they are up to the task. But removing that sense of intimidation for learners can be empowering and inspiring. Using immersive experiences promotes that connection between learner and the concept, inspiring greater inquiry.

CHEMISTRY

Chemistry can be a difficult subject to grasp as learners are often confused by obscure terms and processes. Instructors are always on the lookout for ways to allow students to realize that chemistry manifests itself in everyday life. Distraction-free learning, inside a virtual environment, is  conducive to engaging learners in focused attention on difficult concepts.

BIOLOGY

Life is a wonder, and learning about the intricacies of the world around us, at a biological level, is now within the grasp of learners. Enter into a plant, become a part of an ecosystem, and feel a connection with the smallest particles that make up the basis of life. From genes to proteins, or cells to protoplasm, immersion into this world brings life.

MATHEMATICS

Mathematical concepts are not always easily visualised, handicapping learners who just don’t “get it.” However, Veative has adopted some interesting techniques to introduce students to the world of math, by connecting difficult-to-grasp ideas with real world situations, all in a virtual  world! When a polyhedron is no longer a flat image, but a 3D, interactive  object, it starts to make more sense. When that object can be explored from  the inside, spatial intelligence is activated and a deeper understanding is  within the reach of learners.

Geography

A sense of wonder is what we wish to awaken. Students don’t always get a chance to visit and explore some of the wonders of the world. Imagine taking your learners to majestic places such as Eiffel tower and Taj Mahal  through immersive technology. This allows students to not only feel what it is like in Paris or Agra, but learn about its architect and design at the very  same time.

LANGUAGE LEARNING

VR enables real life experiences, in the safe and comfortable environment needed to ignite language learning. Role-play situations can be enhanced by interacting with virtual people. Scenario-based modules allow a connection between the scene, the context, and the target language. This airport scenario brings learners into a new world, and helps to arouse a desire to learn more.

What is the process for a school to get started?

The main challenge is the hardware. Schools can use their own or ask us a Virtual Reality Classroom Pack. VR CONTENT LIBRARY works with all major VR devices.

Compatibility list

  • Veative VR content also works with all major VR standalone consoles i.e. Oculus Go, PICO VR, Samsung Gear VR & Google DayDream.
  • The handheld controller enables interactivity and navigation, increasing student engagement by promoting active participation
  • Perform virtual experiments and manipulate objects from within an immersive environment

Learning Management PLATFORM

Once the hardware issue is taken care of, next is content. Each student and teacher has their own account. Veative has administrative tools and personalized User Profiles.

Which is necessary a teacher has analytics to schools on usage, assessment scores, proficiency with respect to cognitive domains. Veative provides its own proprietary reporting system for teachers and students to view analytics. Analytics data can also be sent to any other LMS/LRS system (capable of retrieving results), used by schools. The offline version is supported by our proprietary analytics system that stores results locally and syncs with the server when an internet connection is available.

Conclusion

VR opens up many possibilities, and obviously not just in traditional schools. Specialized training, such as for medical procedures, is already happening. Difficult and dangerous job training can greatly benefit from the benefits of doing these tasks virtually while gaining skill and “time in the task.” The virtual world creates a safe environment for learning, so if you make a wrong incision, or set off an explosion in a power plant, VR offers second chances that life often doesn’t.

STEM Technologies in kindergarten

The most intense development of a person takes place in childhood. A child discovers how the surrounding world works. As a result, the teaching of robotics as programming technology in kindergarten significantly narrows the chances of learning the real world and its rules. The most pressing question at this age is “why?”. The transfer of material to children should, therefore, answer this question.

The traditional approach in technology answers the question: “How to do something?”, therefore, for many, robotics is a separate research topic in kindergarten. Let’s compare the STEM approach and regular one.

Let’s look at the examples. One of the most common tasks in robotics is an orientation in the room and step-by-step actions. The directions – right, left, forward and backwards – can be learned by the repeat method. Children repeat the robot’s activities with pleasure. When they press the left or right key again it answers the question: “how?”, in this case: “How do I turn left or right?”

Until then, everything has gone well. Now we take the task step by step: twice to the right, once to the left, one to the right. If you line up the children in two rows of mirror images to check the learned material and ask them to repeat the order at the same time, the confusion will surely begin. This is because there are not links to explain the action in a child’s brain. To the question: “Why I am turning to that angle?” was not answered during the teaching process.

Let’s look at the second approach with the answer to the question: “Why?” Adults often don’t understand the reasoning logic of a child, for which the logical answer to the question is, “Why does a rooster scream?” the answer is, “Because he’s a rooster.” It means that someone has this kind of passion. In other words, if we associate a character with an activity, that’s the answer to the question, “Why?” This communication through a character becomes the checkpoint that a child can use in an unusual situation. In addition, the communication of activities through the character becomes part of the game. Turning to a character is natural. The boys used to play like they were soldiers, the girls played like they were talking dolls, then the boys played Spiderman and the girls played Barbie dolls and Monster High, let’s make a robot or system a character. It provides more opportunities for learning. First, the creative ones, because you have to create a character, second, the sensational ones, because knowledge can be transferred through relationships between the characters. Children easily memorize activities and mimic those they admire.

Let us return to the task of learning directions. Imagine we created three characters. The first one can only go backwards, such as cancer. The other character can only go left, be it the dog running after his tail. And the third character is a sweet-eater who can get a treat if he lifts up his right hand, with which most of us hold a spoon. Learning directions can touch other knowledge that will remain in your memory for a long time. I believe every teacher has already been able to keep thinking about what he would do to complement his character’s story. For example, when imagining cancer, it must be said that he has had to move back quickly so that his natural enemies do not eat him. But cancer wants to be eaten by an otter, water birds, and fish such as a grave and a perch. Therefore, when attacked under water, the cancer abruptly bends its tail, swims back and saves itself in this way. A dog that runs to the left after its tail all the time, runs counter-clockwise, he plays like that out of boredom. The characters created must have their own final story.

Of course, visual shapes, images, video clips, or cartoon clips must beused for a clear image of a character. And, as we have already pointedout, memorabilia takes place through the mutual actions of thecharacters, and it is most interesting for the children. Specifically, noteven the game itself, but the participation in it. Apart from beingmemorable, it is possible to practice social skills here, to help the childopen up. To give children the opportunity to talk when creatingcharacters, they are comfortable sharing in pairs. An important fact isthe possibility of creating a character in a short period of time, becausethere is a great risk of losing interest. Let’s not forget the kids want toplay.

Now we’ll check again how the directions were memorized. Let’s do it in the form of a game. Let’s line up again in two rows and ask children to close the eyes. Give the rotation commands and make pause between commands to give a time for self-control and recall the character story if necessry. Explain to the children that the breaks are given precisely for this purpose. Watch how they get it out and reduce the breaks between commands.

STEM modular kits

The developer of Robo Wunderkind kit took all of the above into account when preparing a training programme for teachers. In order for the teacher to start using immediately, he needs to review the general overview of the composition of the parts of the booklet and then open the lesson program.

Lesson cards explain in an extremely simple way what needs to be done. Each stage of the lesson is divided into parts and has its own description. Each lesson has its own task and is drawn up not only in the form of a teacher, but also in the form of an introductory story for the child. For the sake of comfort, new conditions have been highlighted which will be met during the lesson. In order to verify the acquisition of the completed educational material, the thesis formulates the skills that the child should acquire with the lesson.

A more detailed description of the suites and video references is available in the product catalog STE.education:

Illustrative examples

Soon, a whole series of video lessons will emerge that explain addictions without words. Watch a two-minute video about the features on the switch.

The next just 22-second video is already about how to approach the Halloween theme.

Upgrade options

It should be noted that the manufacturer takes into account the two-year active life of the device. If a base set was originally selected, you will receive ten lesson descriptions along with it. In many kindergartens, hours with five-year-ld children are carried out once a week for an hour,i.e. the first ten hours occur within 2.5 months.

if use chooses Robo Wunderkind educational kit then, in addition to ten basic course lessons, 12 more can be accessed. At the end of this course, or at its discretion in the meantime, additional thematic lessons may be used, such as road traffic rules or animal behaviour.

Then there’s the option to still buy an improved set of innovations. It fitsin with both the primary and education kit. More modules and sensorsthat differ based on functions – more ways to combine these functions.

Interestingly, course teachers often have an interest in trying to combine modules from different sets in one character. Yes, it’s possible. For example, you can take more than one engine and connect to a single control module. Theoretically, the control module supports the 84modules and sensors connected to it. However, we ourselves have not tried to make such a monster, as battery consumption is also increasing. For the development of creative capabilities, adapters are also provided to enable the mechanical parts of the Lego constructor to be added. This makes the design of the character more memorable and attractive.

The company DIFI.NET offers free courses for kindergarten teachers. On courses, you can try the Robo Wunderglove set with your hands and practice a teaching method that answers the question “why”. To register,send your name and contact number to the email ask@ste.education with the subject “why”.

Two weeks before the course, we’ll be sure to warn you as soon as the next group is formed.

uArm usage

uArm robotic arm – entry level for real tasks education

Your Personal Robotic Assistant

One example of how technology is becoming more accessible is the open platform uArm. The uArm is a robot manipulator with four degrees of freedom controlled by Arduino-based stepper motors with an accuracy of 0.2 millimeters. Device developer approach learning by playing. Just invent a problem and solve it. Moreover, the task can be not just moving objects weighing up to 500 grams at 5 to 32 cm, but also the study of remote control through drawing or control via a mobile phone manipulator.

uArm is affordable educational tool for robotic beginners and enthusiasts.

The manufacturer offers several options of complete sets. The most advanced is uArm Swift Pro. It includes add-ons for 3D printing, laser engraving, metal gripping. In addition, the system can be expanded with machine vision, an ultrasonic distance meter, a finger press simulator, a gesture recognition sensor. Of the separately purchased options, it is possible to replace the standard suction Cup grip with an electromagnet or a mini fan. The replacement of standardized plug-in is possible within 30 seconds.

This robot arm is open-source and completely compatible with Arduino, Raspberry Pi, and Seed Studio Grove kits. The fully open architecture of the system allows the device to be freely integrated with other automation systems and to be connected to the software via standard wired and wireless interfaces. uArm is possible to control by smartphone via Bluetooth 4.0.

Since the hand-manipulator has the function of motion recording, i.e. it is possible to move the manipulator with your hand in the learning mode, and it subsequently repeats the motion trajectory exactly, it seems not superfluous to install the PIR motion sensor. “Learn” movements function is accessible without a computer. The base of the manipulator can be expanded by temperature and humidity sensors or colour detection boards. But you can more…

In addition, the system can be expanded with machine vision, an ultrasonic distance meter, a finger press simulator in assist by universal holder, a gesture recognition sensor. Of the separately purchased options, it is possible to substitute the standard suction Cup grip with an electromagnet or a mini fan.

Once you paid, you get a lot of opportunities to study robotics. For purchase, please write to email ask@ste(.) education. (the brackets from the email address must be removed).

Essential chemistry – digital resources Chemistry e-Book

Nowadays e-books for studying become more popular. And from many sides, it is a very wise decision to use a centralized solution, which could be updated immediately if didactic or article author will found it necessary.

Worst practices

I have seen a lecturer who tried to make an e-book with students. It was fun for them to find materials on the internet. It really helps students to study. But soon lecturer recognized a very deep problem. The material chosen by students carefully verified. As a sample, you can find in YouTube video “How to make a MONOPOLE MAGNET”. In Brief in a Video to make monopole magnets recommended to take a regular magnet to freeze it in the refrigerator and cut it in half. If the student read it as a true source of information then he gets to know nonsenseand believe in that. .

Another group of lecturers from different countries agreed to make internal wiki by topics in English for Software development course. It was also very nice idea. And at the beginning it works fine, because of enthusiasms. But on the second year they start to find that materials is going old very quickly. So, it was a problem who will update the topic. Because every lecturer has they own style of giving materials to students. And appears different versions of topic. After that problem went deeper. Because it was already work routine and nobody was interested to edit an articles for free.

All that attempts shows that necessity in that tool exists, but it should be properly organized.

Best practices of E-books

The proper electronic book consists of two parts. One for the teacher and a second one for students. Of course, both parts are linked. And it gives the opportunity for young teachers to give lessons in a proper way immediately after becoming a lecturer. Just because the electronic book is the fully prepared tool for study subject. The properly prepared electronic book has a theoretical block, presentation for lessons, exercise book, test question, tips, video materials, files to research lab equipment and methodical guidance to a teacher. No doubt, that it should be allowed to control students study progress and trough tests and tasks and remotely help if they will need help.
According to that and educational standards are build up PASCO SCIENTIFIC Essential chemistry e-book. More information is here.

Pasco Scentific sensors and PC or tablet bluetooth connection schema

How to connect one PASPORT sensor via Bluetooth® or through a direct USB connection?

The wireless sensor is much more convenient to use. If you have in use wired PASCO SCIENTIFIC Pasport sensors order Airlink. AirLink PS-3200 connect one PASPORT sensor via Bluetooth® or through a direct USB connection. Just plug the sensor in Airlink and collect data in or out of the classroom using computers, tablets or smartphones.

PS-3200

Need more than a single PASPORT sensor per lab station? Multiple AirLinks can be used simultaneously. Watch the video below to see sensor Airlink combo and data acquisition device wireless pairing.

USB Bluetooth Adapter – PS-3500. Simply connect it to an open USB port and then up to three PASCO devices (wireless sensors, Smart Carts, AirLinks) can be connected via Bluetooth. Windows computers, Chromebooks and older Macs can utilize these devices with the help of this low-cost adapter.

AirLink is the most economical way to use PASPORT sensors. The 550 Universal Interface is second option. It also offers Bluetooth compatibility and can be used with SPARKvue software as well as PASCO Capstone software.

DIFI.NET presents National Instruments portfolio

National Instruments product for STEM education

National Instruments (NI) offers the engineering approach, platform and software LabVIEW, through which engineers and scientists around the world design, prototype, run testing, data collection and management systems. It perfectly fits STEM curriculum.

Many people do not think that in the graphical programming environment of robots LEGO MINDSTORMS – this is a simplified LabVIEW. LabVIEW is short for Laboratory Virtual Instrument Engineering Workbench. It was originally released in 1986 for the Apple Macintosh for data acquisition and instrument control. Now there are not only several versions for different operating systems MacOS, MS Windows, Linux, but also two types of classic LabVIEW and LabVIEW NXG. It should be noted that in the development of the first Estonian satellite ESTCube-1, which successfully entered orbit in 2013, NI technologies were also used.

Striving for flexibility NI proposed the concept of modularity of measuring equipment. When various expansion cards can be inserted into the system unit changing the functionality of the main device and getting the synchronization of modules on a single bus. In 1997, NI was one of the founders of the PXI standard, meaning PCI eXtensions for Instrumentation. PXI solution is somewhat similar to a personal computer, where its main parts are a controller and a chassis with a bus connecting all modules, as well as expansion cards. A similar concept is incorporated into the CompactRIO platform, which is often used for data collection. Even for very fast speeds, such as signal processing At the Large Hadron Collider at CERN.

For project education in higher education institutions NI offers:

• NI ELVIS
• USRP
• NI MyRio
• Analog Discovery

NI ELVIS

NI ELVIS (Eng. NI Engineering Laboratory Virtual Instrumentation Suite) is a combination between the platform, which can be expanded by add-on modules and SOFTWARE allowing to design printed circuit boards , as well as to make measurements from the connected platform. ELVIS combines such devices as:

  • function generator
  • arbitrary waveform generator
  • Bode analyzer and impedance analyzer
  • oscilloscope
  • digital multimeter (DMM)
  • dynamic signal analyzer (DSA)
  • digital reader and programmer

Due to the modules, the ELVIS platform can be used for laboratory workshops on analog and digital electronics, power electronics, mechatronics, linear and nonlinear control systems, communication systems.

USRP

USRP (Eng. Universal software Radio Peripheral) – software reconfigurable radio input / output device. These are devices of reception and transmission of radio waves in which you can change the type of modulation, do tuning of operating frequencies, and quickly make changes to the system as new requirements and standards of communication by updating the software.

MyRIO

MyRIO is this controller, often used as the basis for controlling robotics. More than 10,000 educational institutions around the world use MyRIO for training and preparation for robotic competitions, such as (WRO, FIRST), as well as in the subsection “Mobile robotics” WorldSkills. The controller is popular because it has a sufficient number of digital and analog inputs / outputs, built-in accelerometer, FPGA Xilinx and dual-core ARM Cortex-A9 processor, support Wi-Fi, USB port. It can be programmed with the help of LabVIEW or C. It is also the “brain” of TETRIX PRIME plus MyRIO.

Futurologists say that very soon to repair the car, for example, spare parts will not be sent from the factory, and they will be printed on the requested model on a 3D printer in the workshop for drawings received from the database of the plant that developed and tested the part. In many schools now it is possible to use a 3D printer.

As if anticipating the promises of futurists PASCO SCIENTIFIC offers to expand the functionality of manufactured products using 3D printing. For example, for a smart cart, it is possible to print some additional parts. Use 3D printing for the sake of clarity of the learning process. DIY means do-it-yourself. Use DIY parts for PASCO SCIENTIFIC Smart cart enlargement.

3D cover for smartcart

In the PASCO WEB DIY section https://www.pasco.com/diy/ you will find 3D models drawing files in the format Solid works (.SLDPRT).

Popular for download statistics is the case for a smart cart. He dresses over a Smart Cart and visually increases it several times. In this case, it can also be demonstrated on a metal rail. This means the built-in encoder works as does the 3-axis accelerometer and gyro.

For the convenience of printing on small printers, the case is divided into parts, which after print are glued together.

STEM in Chemistry

Tie-dying is always a great year-end experiment and as chemists. A real bonding experience is fun to guess which student will end up with the most dye on their arms. Students also have an opportunity to incorporate chemistry in a meaningful way while creating a nice keepsake.

First, you’ll want to purchase reactive dyes since they are very brilliant and colourfast. They actually bond with the fabric, making the colour on the shirt last longer and the chemistry more interesting. Despite student protest that this is “just supposed to be fun”, tie-dying is an opportunity to review concepts of concentration, absorbance and transmittance. With a PASCO Wireless Spectrometer (PS-2600), you can explore the absorbance of the different coloured dyes before you start the process of colouring your shirts.

To really engage students in the technique of dying and in engineering process skills, the experiment can be opened up to student inquiry. Some things they could investigate as they try to create more vibrant colors include:

  • Comparison of reactive dyes, union dyes and acid dyes
  • Preparation and use of natural dyes
  • Comparison of synthetic and natural fabrics
  • Dying conditions like temperature, time and pH
PASCO CHEMISTRY in life

To explore natural dyes create a yellow dye using turmeric, a red dye using beets, a purple dye using blackberries and a blue dye using red cabbage. It is possible to change the red cabbage blue by adjusting the pH of the solution. The results on the fabric are mixed, but because of the real-world application of science and engineering practices, the student learning is very real.  And if nothing else, everyone gets to take home a really cool shirt.

More labs with spectrometer

With the Wireless Spectrometer you can also perform these labs:

  • Emission spectra of light
  • Absorbance and transmittance spectra
  • Beer’s Law: concentration and absorbance

What for Pasco Wireless Light Sensor


The Pasco Wireless Light Sensor: See the Light. And Measure it too. By Martin Horejsi | Published: September 18, 2017 in National Science Teacher Association Blog

Pasco wireless light sensor is a plastic box with a dynamic and versatile sensor that effectively measures many forms of light, and gives the science class a peek into how we learn about the universe we live in. Yes, the Pasco Wireless Light Sensor could easily go unnoticed in the science room’s box of technology. It would be understandable to think that this is just another sensor designed to fit into a lineup of other sensors. In fact, there really isn’t much on the sensor to indicate just how powerful and versatile this particular sensor really is. There is only one button, the on/off switch. There is a tripod socket, a few words here and there printed on the case, and two apertures, a short black tube for spot measurements, and a flat white circle for ambient measuring. Like I said, uneventful.

Light sensor measurement scope

But like most amazing gadgets these days, the real show begins when the device is paired with its software. So this little box measuring not much more than 2 x 4 x 7.5 cm actually has the capability to measure:

  • Red light
  • Green light
  • Blue light
  • White light
  • Illuminance in lux
  • Illuminance in lumens per square meter
  • PAR (Photosynthetically Active Radiation) in sunlight
  • Solar Irradiance in watts per square meter
  • Ultra-violet A (UVA)
  • Ultra-violet B (UVB)
  • Calculate the ultra-violet index (UVI)

Further, the sensor can be so simple in appearance because the data leaves the sensor at the speed of light (in air) travelling over low energy Bluetooth radio waves to any receiving computer, tablet or phone. With a range of about 10m and an easily replaceable CR2032 battery, the Pasco Wireless Light Sensor is an about as perfect a light tool as a teacher can imagine. And speaking of light, it’s pretty much the only thing we get from the universe beyond the earth besides meteorites, solar wind, and sample return space missions, and that list is pretty short.

There is an abundance of concepts to study and light to measure so it follows that there is no shortage of traditional and innovative experiments for any grade level. The Pasco Wireless Light Sensor can easily measure the presence, absence and quantity of a handful of different kinds of light. And with each measurement, there is an ever expanding realm of possibilities, variations, and real-world analogs.

For instance, measuring sunlight is an obvious use of the Pasco Wireless Light Sensor, but wait, there’s more. That same sunlight can be reflected off surfaces, filtered through an endless number materials, fabrics, lotions, and films. UV through clothing can be measured with the fabric dry and wet. Sunscreens can be tested. Sunglasses, auto glass, and windows can be explored. And all of the above can be refined further by applying variables of distance and angles.

Mount accessories

A bonus about the size of this sensor is that it happens to be the right size to fit into cell phone cradle or tripod mount. This fact allows the Pasco Wireless Light Sensor to be used effectively in existing and handy stands that can aim Sensor as needed.

Wireless Light Sensor use cases

Pasco Wireless Light Sensor’s unique ability is measure four colors of light…well three colors and their combination totaling up to white. The quantity of light moving through a filter, say sunglasses, is rarely across a uniform distribution of visible wavelengths. While we often worry about the amount of UV and IR in our sun shades, there are implications for colors. If sunglasses change colors or make them look similar, say green and red, then horizontal traffic lights could be read backwards. Another example is that sunglasses used around water may need to filter much more blue light than sunglasses used for other sports.

The inverse square law can be verified using little more than a meter stick, light source, and of course the Pasco Wireless Light Sensor.

Two different apertures allow the Pasco Wireless Light Sensor to measure ambient light and narrower directional light sensor. The ambient sensor measures UVA, UVB, and UV index. The spot sensor measures general light level in several units, as well as relative intensity of red, green and blue light, or all three together as white light.

Data reading from Wireless Light Sensor

Bluetooth 4 is the Pasco Wireless Light Sensor communication method with iOS and Android mobile devices, and Mac and PC computers. A list of compatible hardware and software is listed here.

By removing the cables and going wireless, it’s possible to put the sensor in places where it might not be safe to be within the usual meter of wire, such as out in the sun for an hour. The Pasco Wireless Light Sensor can also be set up as a lab station where students log into the sensor to gather their data, then move on to the next station.

The Pasco Wireless Light Sensor is an excellent tool to teach science, and to do science. It’s tiny form factor and huge set of capabilities, but what makes it even more of a go-to solution is that the Pasco Wireless Light Sensor talks to smartphones putting a tremendous amount of science lab into a single pants pocket.

Light is an amazing thing. And even though it is wildly prolific in the known universe, it’s Wikipedia entry is still less than half the length of that of Michael Jackson’s entry. Or about the same as an avocado. But whether you think the light is a particle, a wave, a combination explained by electromagnetic, or quanta or likely all (or none) of the above, light is an important aspect of almost every scientific subject. Which, given that line of reasoning, the Pasco Wireless Light Sensor just might be the most universal sensor when learning science.
