Light travels in a straight line until it strikes an object. Light can be reflected by a mirror, refracted by a lens, or absorbed by the object. (Page 127)

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

Magnets attract and repel each other and certain kinds of other materials. (Page 127)



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

Things near the Earth fall to the ground unless something holds them up. (Page 94)

Magnets can be used to make some things move without being touched. (Page 94)
