Maria's Toy Car Experiment
Maria wants to know if a toy car rolls farther on a smooth floor or on a rough carpet. She uses the same toy car and pushes it with the same strength each time.
She did her experiment and wrote down her observations:
- On the smooth floor, the car rolled 10 feet.
- On the rough carpet, the car rolled 3 feet.
What question was Maria trying to answer with her experiment?
Based on Maria's observations, on which surface did the car roll farther?
If Maria wanted to make sure her results were correct, what is one thing she could do next in her experiment?
