Slow Down... Activity Sheet

1. Collecting Data

• Test the truck-and-ramp system
• Do three trials
• Calculate and record the speed of the truck (discance / time = speed)

2. Predicting

    Which material will best reduce the speed of the truck on the ramp?

    How will you modify the truck-and-ramp system?

3. Testing

• Prepare your modified truck-and-ramp system
• Test the dump truck on the ramp
• Do three trials
• Calculate and record the speed of the truck (distance / time = speed)

4. Comparing Data

    What was the average speed of the truck without the modification?

    What was the average speed of the truck with the modification?

    How did your modification affect the speed of the truck?

5. Your Conclusion

    Why do you think your modification affected the speed of the truck in this way?
