Evaluating Pod Claims 

Activity 3 - Explaining Thruster Forces – CER handout 

You will write a cause-and-effect relationship between the force exerted by the thrusters and the pod’s change in velocity. By providing detail, you will help the space agency interpret the data. 

1. Explain the events that would cause the changes in velocity. For each claim, describe the thruster force and how that would result in the pod moving away from the station 

2. In your claim, use the word bank, cause-and-effect words and phrases, you CER reference sheet, and your two Modeling Tool diagrams to help you write your claims 

CLAIM 1: The thrusters caused the pod to move in the opposite direction 

CLAIM 2: The thrusters only slowed the pod, it didn’t stop; the pod hit the space station, which made it bounce and move in the opposite direction
