Strand IV
Use Scientific Knowledge from the Physical Sciences in Real-World Contexts

 

Science/Strand IV
Content Standard 3
All students will describe how things around us move and explain why things move as they do; demonstrate and explain how we control the motions of objects; and relate motion to energy and energy conversions. (Motion of Objects)

Science/Strand IV/Content Standard 3/Elementary
Benchmark 3
Describe patterns of interaction of magnetic materials with other magnetic and non-magnetic materials.

Benchmark Clarification

Interactions between magnetic materials and non-magnetic materials form patterns. Magnets have two poles, called north (N) and south (S). Opposite poles attract (N-S) and like poles repel (N-N or S-S). Some materials are attracted to magnets and some materials are not. Magnetic forces operate through materials and over a distance.

Students will:

  • Observe the effects of magnets
  • Describe the effects of magnets using appropriate terms

Instructional Example

Benchmark Question: How do magnetic objects interact with other magnetic or non-magnetic material?

Focus Question: How do magnets react with a variety of objects?

The teacher will provide students with magnets of different sizes and shapes, as well as a variety of objects, some magnetic and some non-magnetic. Each student will write predictions about how a magnet will react to each object.

Students in small groups will choose four objects and one magnet. They will take turns and test their predictions. Each student will record the results of his or her tests in the chart.

Assessment Example

Using marked magnets, students will arrange magnets in different patterns. Each student will circle his or her predictions on the chart and then test each prediction. Each student will circle the result of each test on the chart.
