These questions are harder than they look:

  • A tree seed starts very small, but where does all of the stuff that makes wood for chairs and tables come from?
  • Can you make a bulb light with just a battery and a single wire?
  • Why is it hotter in summer?
  • Draw a picture of the solar system. What shape are the planets’ orbits?

Answers in Jonathan Drori’s TED video (though some would debate even his answers – science is fun).

And a link since no one believes me when I tell them the answer to the 4th question.
