srp-ing

after finishing my experiment and re-doing it, i've got the results down on paper and will conclude them. for background info, i've been looking around google for stuff about the materials of balloons, whether colour matters, information about different conditions and also similar experiments to my own.

science experiment

i have just finished blowing up 12 balloons, recording measurements and setting them up in their conditions.i finished around 6:30pm, so on saturday around this time, i'll see how they went and re-measure

i noticed some things when doing my experiment:

the non-metallic balloons
- are much easier to blow
- are softer

the metallic balloons
- are harder to blow
- are stiffer

Method

Three non-metallic blue balloons were blown up to its maximum and each was put in: a dark room (cupboard), in a lit room and an outdoors area. Each balloon was marked with a permanent marker, according to their environment. This process was repeated with three metallic blue balloons, three non-metallic white balloons and three metallic white balloons. Each balloon was measured around the maximum circumference and this was recorded. The balloons were left in each of these conditions for four days. The maximum circumference of each balloon was measured four days later. These results were recorded and the differences were calculated. Any other observations were also recorded. This experiment was repeated again.
