## Reflection: Rigor May the Force Be With You! - Section 5: Active Engagement #2

The biggest struggle during this lesson was controlling variables. Students were learning to place the metal rings into the cups in a controlled way, pay attention to where their hands were, and placing one ring in at a time.

My conversations with each group moved to variables. This is rigorous for the students. They must learn to consider everything that makes an experiment valid, and then discuss with their group how to control them.

As a guide, I must continue to discuss this aspect of science with my students and I must continue to model how to choose a variable to test and how to control the others.

# May the Force Be With You!

Unit 8: Magnets
Lesson 4 of 7

## Big Idea: This lesson is due to a student's question about how the force of his magnet was breaking when he moved his arm quickly. The motivation today is high because it is a student's idea.
