method:
1. collect three different material of balloons
- rubber
- latex
- polychloroprene
2. inflate 3 rubber balloons, 3 latex balloons and 3 polychloroprene balloons
3. place a latex, rubber and polychloroprene balloon in an outside environment
4. start the timer
5. place a latex, rubber and polychloroprene balloon in the fridge
6. start the timer
7. place a latex, rubber and polychloroprene balloon in at room temperature
8. start the timer
9. record results
10. repeat steps 2 to 9 three times

SRP

independent variables- the temperature of the three different conditions

dependent variable- time it takes for the balloon to deflate

controlled variable- how much air is going to be pumped into the balloons
- use the same 3 different materials
