climate graph


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

    the rate of deflation of foil balloons is longer than rate of deflation of latex balloons

  2. Cherry, if this is all you have done, I certainly am worried about your project. It is not researched at all, nor is the method in enough details for it to be replicated. Your posting online is sparse and vague. Use this avenue better and certainly do more work.
