Energy Sources

With 10 questions, this quiz looks at the fuels and energy sources that power everyday machines. You complete lines like Nuclear submarines run on ... or A flywheel stores ... energy by choosing the right source. It works well for students connecting science class to real vehicles and devices. The standout fact here is about the sun itself: it shines because of nuclear energy happening deep inside it, the same basic process that powers the brightest objects in the sky. You will also cover gasoline, kerosene, coal, and the chemical energy in your phone battery. Recommended level: beginner.
