This project explores planetary motion using shadow drawing:
Every morning the Earth spins or rotates so that the side you are on faces the sun. As the Earth spins you see the sun come up over the eastern horizon. As the Earth keeps spinning and your day progresses, the sun seems to move across the sky. When the Earth turns so that the side you are on faces away from the sun, you see the sun disappear below the western horizon. From where you are, on the surface of the Earth, it looks like the sun is moving—but it is really the movement of our own planet that makes the sun seem to move and the shadows change.
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!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
