Energy: stored and moving
Answers are for parents and teachers.
1
Draw something at home that has potential energy and say why.
Answers differ, for example a book on a high shelf: it is high up and could fall.
2
List three things that have kinetic energy on your way to school.
Answers differ, for example a bus, a bird, a person walking.
3
A ball is thrown up, stops for a moment at the top and falls. When does it have the most potential energy?
At the top, where it is highest.
4
Draw an energy change for a radio or a lamp with arrows and boxes.
Radio: electrical in, sound out. Lamp: electrical in, light and heat out.
5
Explain to someone at home why a roller coaster can go fast without an engine after the first hill.
The first hill gives it potential energy, which changes to kinetic energy as it goes down.
