1. The document outlines a plan to build a model car using motors, batteries, wheels, and a board base to test different design factors that impact speed. 2. Their initial tests found that using a lighter base and repositioning heavy batteries improved the car's speed and performance. 3. The students concluded that homemade model cars can be a fun toy to race against friends and suggested ways to further optimize design in future projects.

Making a Model car

2. How Do You Make A Model Car?

3. •Will it matter if we put the motors in the front?
• If we use 4 motors, will it go faster?
• Do we have to use a lighter base?
Questions

4. • We think it will go faster if we use a lighter base
Prediction

5. 1. Draw a diagram to get a idea
2. Attach two motors to the board
3. Attach wires and switch to motor
4. Attach wheels to motor with sticky tack
5. In two small battery holders, put in two AA
batteries.
Plan

6. • We needed a lighter base.
•The batteries were weighing down the car
•We need a bigger base
Results

7. • I claim that you can make a model car without
buying one at the store
• I can prove this by showing right now
• Our results show that we need a lighter base
• We found out that the batteries were weighing
the car down
• You can use this in real life as a toy for racing
your friends
• Next time I would change the weight of the car
• I still wonder if you put the motors in front, if it
will go faster
Conclusion

8. 1. Racing your friends
2. Having fun
