Level 2: Stored and moving

Energy and power · level 2 of 8 · rough age 7-8 (a guide for parents; anyone can start anywhere)

In this level you meet the main kinds of energy: the energy of moving things, the energy stored in things lifted up, stretched or squashed, and the energy carried by heat, light and sound. You see energy change from one kind into another, and find out why a rock lifted on Mars stores less energy than the same rock lifted on Earth.

Lesson	You will be able to
Moving energy	Say which of two moving things has more energy, and why
Up high	Explain that lifting something stores energy, and why it stores less on Mars
Stretched and squashed	Explain how springs, elastic bands and bows store energy
Energy changes form	Follow energy as it changes from one kind into another
Heat is energy too	Explain that warming something needs energy, and cooling gives it out
Light and sound carry energy	Explain that light and sound carry energy from place to place
