What questions do you have?
- Talk about why the highest horsepower might not be that fast (10,000 horsepower vehicle that you could beat with a Toyota Prius).
- Ask what other things are important for going fast. Is the lightest vehicle always the fastest (Would you want this 326 pound vehicle in a drag race)?
Have the students record the type and horsepower for each car.
Make sure they make a prediction of the fastest car by putting their initials next to their guess.
- Have the students do some research to find the curb weight for each car.
- Discuss how we could use this information to make a prediction of the fastest car. How do we compare numbers (+,-,*, or / ?). Do we want horsepower or weight on top of the fraction? Is a higher or lower number better?
