Materials needed for amplify unit 2 in 3rd grade balancing forces activity. Included 8 bags of each:
- 1 bag, plastic, self-sealing (bag of materials prepared in Lesson 2.1)
- 1 brass-plated paper fastener (brad)
- 1 solid-brass paper fastener (brad)
- 1 small paper clip
- 1 steel spoon
- 1 plastic spoon*
- 1 twist tie with iron core
- 1 washer
- 1 piece of steel wool
- 1 scrap of aluminum foil
- 1 piece of wood (craft stick)
- 1 balloon
- 1 penny*
- masking tape*
Students discover that some forces can act without objects touching. Students plan and conduct investigations to test
if a force can be exerted between two objects without the objects touching. They discover that this can indeed happen
between magnets and some other objects.Students discuss and write about the evidence they gather about non-
touching forces. The teacher then models the use of the Force Diagramming Tool to diagram two magnetic forces.
Students activate their prior knowledge about magnets by using an anticipatory chart. The purpose of this lesson is to
introduce students to magnets, magnetic force, and non-touching forces—important concepts they will investigate
further throughout the unit.
