My idea for srp is to investigate what conditions keep a balloon maximally inflated for the longest period of time.
Method:
1. Blow up two metallic and two non-metallic balloons of the same colour
2. Repeat step 1 twice, with another two different colours
3. Name each balloon accordingly (for example; a purple, metallic balloon that would be in a dark room would be named "PMD")
4. Measure around each balloon both vertically and horizontally around the largest areas and record the results
5. Put one metallic balloon and one non metallic balloon of the same colour in a dark room (such as a cupboard)
6. Repeat step 5 for the other two colours of the balloons
7. Put one metallic balloon and one non metallic balloon of the same colour in a lit up room (such as in a spare room including a light that will be turned on for three consecutive days)
8. Repeat step 7 for the other two colours of the ballons
9. Observe, measure the differences in sizes and record the results three days later
The independent variable would be the colour (e.g. pink, blue and yellow) and style (metallic vs. non-metallic). The dependent variable would be the size the balloon would shrink to after three days.

You need to give a little more thought into this and you need to test it multiple times to ensure the same result.
ReplyDeleteHow are you going to ensure that they are the same size to begin with? Is that going to affect your results?
