Flashcards: Predictions of Future Motion Through Patterns
Ashley wants to investigate how objects move and see if she can make correct predictions. She knows she will have to observe the object's motion. She wants to see which surface material will allow a toy car to get down a ramp in the least amount of time. She tests the car on wood, plastic, carpet, and grass.
Which answer choice lists a reasonable observation that Ashley may make?
"The toy cars on the grass and carpet moved very slowly, if at all. The cars on the wood and plastic moved quickly. The car on the plastic got down the ramp in the least amount of time."
"The toy cars on the grass and carpet moved very slowly, if at all. The cars on the wood and plastic moved slowly also. The car on the wood got down the ramp in the highest amount of time."
"The toy cars on the grass and carpet moved very quickly. The cars on the wood and plastic moved slowly. The car on the plastic got down the ramp in the highest amount of time."
"The toy cars on the grass and carpet moved very quickly. The cars on the wood and plastic moved quickly. The car on the wood got down the ramp in the least amount of time."
