It's more important than ever to understand how we can harness energy from the world around us in environmentally-conscious ways. And what better way to learn those concepts early than with your very own solar house? With a solar panel atop the roof, you'll build circuits to understand how to save solar energy, simulate the sun with your own flashlight, and use it to light up your house. Plus as Piperbot and Pip learn how Zomars on Mars conserve their solar energy before a sandstorm, you'll be learning some of the most important lessons about clean energy. This kit includes the Solar House lesson free and accessible on make.playpiper.com. The Solar House is an add-on and REQUIRES a Piper Make Starter Expedition Kit with the Raspberry Pi Pico to get started (sold separately).
