Reflection: Complex Tasks Collision Course (Part 2) - Section 2: Engagement


I know that some of the experiments my students ran had some design flaws.  Every time I saw a student introduce a second variable, or make a claim that wasn't quite true, I had to ask myself what the days objective was.  The important thing was not whether they understood angles of forces, or kinetic vs. potential energy, but instead how can they plan and conduct a fair test.  This would not have been possible with a neat and tidy lab from a science book, even if it eliminated all the other confounding variables.

Collision Course (Part 2)

Unit 2: Energy and Motion
Lesson 3 of 4

Objective: SWBAT conduct an experiment, collect data, and draw conclusions about the changes in energy that occur when objects collide.

Big Idea: How can you conduct an experiment to explain how speeds change when objects collide?
