# Lab Report: Testing How Many Balls a Toy Car Can Move

 First Name: Aaron Age: 6 Experiment Title: Testing How Many Balls a Toy Car Can Move What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.: I was hoping to learn how many balls a toy electric car could move. Every try would be a different type of track. That will tell you what type of track is harder for a car to move things around. What was your hypothesis?: My hypothesis for Double Circle was that the car could push 2 balls around it. My hypothesis for Small Circle was that the car could push 5 balls. My hypothesis for Up-the-Wall-Figure-Eight was that the car could push 0 balls, because the track went up the wall so I thought that when it went up the wall the balls might be too heavy for the car. What materials did you use in your experiment? List them all.: 1. Zoom Tubes Car Trax (tracks, remote control, and car) 2. 7 balls What procedure was followed? Provide a brief description of the steps you followed during your experiment.: Step 1: Make three shapes of tracks, and they can’t be the same. Step 2: Charge your car. Step 3. Insert your car into the first track. Step 4: Get your remote control and put one ball into the track. Step 5: Turn your car on. Step 6: Use your remote control to move the car forward. Step 7: If you can get one ball around the track, then insert another ball into the track. See how many balls the car can push.Repeat steps for each other track. What were the results of your experiment?: The results of my experiment were:The car in Double Circle could push 1 ball through the track once. The car in Small Circle could push 4. The car in Up-the-Wall-Figure-Eight could push 0. What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect?: For 2 out of the 3 tracks, my hypotheses were not right. But for both of those, my hypotheses were 1 away from what actually happened. For the third track, I was right. Spend a few minutes learning about the scientific principles involved in your experiment. Write 3-4 sentences about what you learned and how it relates to your experiment.: I learned that mass and weight are not the same. Mass is how much “stuff” things have. Weight is how heavy it is, which is related to gravity.So on the different tracks, the weight of the balls mattered more than the mass. On the Up-the-Wall-Figure-Eight track, there was more gravitation pull because it went straight up. That meant it was harder for the car to push the balls because there was too much weight.
