Buggy Velocity Project Review

Did the type of toy car affect the speed of the car?

• Yes

• No

A hypothesis can be described as an:

• Educated guess

• Subtle suggestion

• Mystifying puzzle

• Complex conundrum

Materials you might have used to complete the project include:

• Two toy cars, a tape measure and a stop watch or cell. phone.

• Two toy cars, a ramp, skateboard, stop watch or cell. phone.

• One toy car, a toy boat, stop watch or cell. phone, and a ramp.

A correct sequence for the procedure you may have used is:

• 1. Get materials. 2. Choose one of the two toy cars. 3. Measure out a distance of 5 meters putting a mark for every meter measured. 4. Roll the toy car across the floor. 5. Measure the time it took the car to travel every meter for 5 meters. 6. Record data in data table. 7. Repeat steps at least two more times. 8. Repeat for the other toy car.

• 1. Get materials. 2. Record data in table table. 3. Measure the time it took the car to travel every meter for 5 meters. 4. Roll the toy car across the floor. 5. Measure out a distance of 5 meters putting a mark for every meter measured. 6. Choose one of the two toy cars. 7. Repeat steps at least two more times. 8. Repeat for the other toy car.
