Director's Cut: Trial 3
The point of trial 3 was to do a greatly simplified (only 3 GRB, obvious difference in size but same shape, and that shape is easy to make) experiment incorporating the changes in measuring volume. Hopefully it could have revealed that GRB do expand after cooking and previous measurements were just not accurate enough to show that.
In this trial, the density still increased after cooking, but to a maximum of 16+% as compared to trial 2's 30+%. As I was conducting the trials, I've realised that accurate measurements were the most important aspect.
Most significantly, after looking at my apparatus my teacher said that a spring balance was far too inaccurate for this experiment, so I'm going to have beg, borrow or steal a better one. Honestly, they're much more expensive and the rare people who have them worry about lending them out...
