Kinetic and potential energy, heat transfer, waves, reflection and refraction, color and the science of sound.

A science course for grades 6–8. Every lesson explains one big idea in clear, kid-friendly words, shares amazing facts, sets a hands-on activity using everyday materials (with grown-up helper notes) and ends with a short quiz that explains each answer.
