6.A Develop an initial model to describe how forces and energy transfer in magnetic fields explain cause and effect relationships between parts of a speaker system (magnet and coil of wire).

This exit ticket is designed to assess students’ application of the cause-and-effect sentence starters to make predictions about the interactions between magnets when distance or orientation of the magnets change. An ideal response might look like this:

• When we bring the magnets close together when the forces are attractive, then we will observe energy transfer so that they move toward each other and stick together.
• When we bring the magnets close together when the forces are repulsive, then we will observe energy transfer so that they fly apart.

The prediction is useful as a tool for motivating the activity in the next lesson. You will refer to some of what you saw in student responses at the launch of the next lesson. Read through a representative sample for this purpose. The most important thing for individual student assessment is not the content of the prediction, but the students’ comfort with using the cause-effect sentence starters to formulate their predictions. If students are still struggling to apply this structure to their predictions without a more-explicit scaffold, return to the Lesson 1 slides introducing the fill-in-the-blank scaffold to describe cause-and-effect relationships. Insert these slides at the beginning of Lesson 7 and use a familiar system (e.g., a falling cell phone) to practice making predictions. You might consider using a video of a Rube Goldberg machine to practice describing cause and effect.
