Forces that Attract and Repel – Science Gallery
30 + 60 minutes – $5.25/student
Includes 60 minutes self-guiding time in the Science Gallery
Curriculum Target Grade: 3
This demonstration introduces students to the different forces that surround them. Students learn to define forces as a push or a pull, and participate in activities that demonstrate the forces of gravity, magnetism, and electricity. An electromagnet and Van der Graff generator are used for some spectacular demonstrations. This 90-minute program includes a 30-minute demonstration and 60 minutes of self-guided time in the Science Gallery.
3-3-01 Use appropriate vocabulary related to their investigations of forces. Include: force, attract, repel, gravity, magnet, magnetize, magnetism, north pole, south pole, magnetic field, compass, electrostatic charge, static electricity, electrostatic force
3-3-02 Recognize that force is a push or pull and that attraction and repulsion are types of pushes and pulls.
3-3-03 Describe evidence showing that objects and living things on or near Earth are pulled toward it by a force called gravity.
3-3-07 Demonstrate that opposite poles attract and like poles repel.
3-3-11 Describe and demonstrate ways to use everyday materials to produce electrostatic charges.
3-3-12 Investigate to determine how electrostatically charged materials interact with each other and with uncharged materials.
3-3-16 Recognize that gravitational, magnetic, and electrostatic forces can move certain objects without touching them directly.
3-3-18 Identify devices that use gravitational, magnetic, or electrostatic forces.
