Thanks to our sense of touch, we can all tell the difference between hot and cold. But does the same temperature always feel the same? Have you ever noticed that the bathroom tile feels very cold to your bare feet but your towel, which has been hanging in the same room, feels warm? Why is there such a difference? Try this fun activity and find out!
First we need to consider energy. Heat is a form of energy. When an object gains heat the object’s molecules gain kinetic energy and they move faster. Temperature is the objective measure of the average speed of the molecules.
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
