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 balloon
My SRP is on the deflation of balloons
Aim: to observe the rate of deflation of different materials of balloons under different circumstances
Hypothesis: the higher the temperature the faster the balloon deflates.
Method:
1. Buy 3 already inflated foil balloon
2. Inflate 3 latex balloon to the same size as the foil balloons
3. Place a foil balloon in the fridge
4. Start the timer
5. Place a foil balloon in the backyard
6. Start the timer
7. Place a foil balloon in a room(at room temperature)
8. Start the timer
9. Repeat steps 3 to 8, but with a latex balloon
10. Record results of time taken for the balloons to deflate
11. Repeat the above 10 steps 3 times
