II.I.II.1

Observe how energy does things (e.g., batteries, the sun, wind, electricity).

Observe and describe how energy produces changes (e.g., heat melts ice, gas makes car go uphill, electricity makes TV work).

Know that there are different forms of energy.

Describe how energy can be stored and converted to a different form of energy (e.g., springs, gravity) and know that machines and living things convert stored energy to motion and heat.

Describe the usefulness of some forms of energy (e.g., electricity, sunlight, wind, sound) and how energy (e.g., heat, light,) can affect common objects (e.g., sunlight warms dark objects, heat melts candles).
