Phase: | During/Explore/Explain |
Activity: | 1. Teacher shows the video on ultimate chain reaction to students. 2. The teacher leads a discussion of what students noticed when watching the video. Make a chart of all the items noticed such as the force needed to knock down the next item, the kinetic energy as items move, and which object has potential energy. 3. Students are placed in groups of no more than 4 students to work as a team to create a chain reaction. 4. Students use items from around the classroom to make a chain reaction as a team. 5. Students test, evaluate, and improve their chain reactions until they work all the way through the chain. 6. Students share chain reactions with the class and use evidence from the investigation to describe changes in energy that occurred when the objects collide. 7. Students write a reflection paragraph about what they learned and must use the key terms force, cause-and-effect, potential energy, and kinetic energy. |
Assessment Strategies: | The teacher can assess student understanding by observing their chain reaction models and analyzing their reflection paragraph to determine if students used evidence collected from investigations to describe changes in energy that occur when objects collide. |
Advanced Preparation: | Students will need to know the definitions of force, motion, kinetic energy, and potential energy. |
Variation Tips (optional): | Teachers can set certain materials for the chain reaction instead of using any material in the classroom. |
Notes or Recommendations (optional): |
