Students are investigating gear trains in Science! Ask your child:
If you turn a gear clockwise, which direction will the next gear turn?
How can you get a gear to turn in the same direction as another gear?
What does gearing up mean? What does gearing down mean?
What is a rack and pinion? How does it work? Where would you see one?
