6th - 8th Grade Module 3 Concept 2

Cycle 1

How do the speed and mass of an object affect kinetic energy?
Cycle Summary

In Cycle 1, students will come to answer the question “How do the speed and mass of an object affect kinetic energy?” To do this, students will first make observations and predictions about the amount of kinetic energy runners have. Students will then conduct an investigation to determine how speed affects kinetic energy. Students will then obtain information and analyze data to draw mathematical connections between kinetic energy and speed. Once students determine the relationship between speed and kinetic energy, they will conduct an investigation to determine the mathematical relationship between mass and kinetic energy.

Explore

Students collect and analyze data to determine the effect of speed on kinetic energy.

Session 2
Explore

Students collect and analyze data to determine the effect of speed on kinetic energy.

Session 3
Explain

Students critically read text to make the connection that by doubling the speed, the kinetic energy is quadrupled.

Elaborate

Students collect and analyze data to determine the effect of mass on kinetic energy. Students complete practice questions over the relationship between energy, mass, and motion.

Session 4
