Alaska Science
Key Element A8c

A student who meets the content standard should understand the scientific principles and models that state that whenever there is a transformation of energy, some energy is spent in ways that make it unavailable for use (Energy Transformations).

Performance Standard Level 1, Ages 5–7

Students observe that there are many ways to produce heat and other forms of energy.

Sample Assessment Ideas

• Students demonstrate and/or explain three ways to warm hands on a cold day.

• Students list several different forms of energy and identify a source for each in their home or community.

Heat can be produced in many ways, such as burning, rubbing, or mixing one substance with another. Heat can move from one object to another by conduction. (Page 127)

Electricity in circuits can produce light, heat, sound and magnetic effects. Electric circuits require a complete loop through which an electric current can pass. (Page 127)

Sound is produced by vibrating objects. The pitch of sound can be varied by changing the rate of vibrations. (Page 127)

The sun provides the light and heat necessary to maintain the temperature of the Earth. (Page 134)

Benchmarks

The sun warms the land, air, and water. (Page 83)
