1. Battery vs. Battery

2. Problem
Which battery will last longer a
frozen battery or a regular
battery in a RC car?

3. Hypothesis
Based on the research the frozen
battery will last long bacause the
temperature will freeze the usage of the
electricity

4. Materials
- Bowl
- R.C. car
- Cloth
- Freezer
- Batteries
- Table

5. Photos

7. Results
The frozen battery
lasted longer in a R.C.
car because the electric
production was slowed
down.
