When a scientist finishes an experiment, she always writes up her notes and analyzes her data. Write your analysis here, starting with a few simple questions.
Look at the average times of your races. Which version of your car was the fastest?
Did any modification substantially improve your race time?
Why do you think that is?
Do you think the ramp had any effect on how fast your car went? Why?
Take a look at your neighbor's car and your family's car. If these were the shapes of two Pinewood Derby cars, which do you think would be the fastest and why?
Did anything you learn surprise you? Write it down here to keep a scientific record.
What can you do to make your car go faster? (Change the shape? Adjust the ramp?)
