Yesterday, I had a consultation session with Ms Tan, my Science teacher. It was a most fruitful session, and I picked up many tips about how to improve my experiment!
Experiment
1. My control should be the one in tap water, and not the one exposed to air since all the other peaches were immersed in a kind of liquid.
2. It is better to record the appearance of the peaches at regular intervals e.g. after every 10 min, instead of my earlier design, which was to record their appearances at 5 minute intervals for half an hour (6 times), then at 15 minute intervals for the next 1 hour (4 times), then at 30 minute intervals for the next 2 hours (4 times).
3. When I take pictures, the curtains must be closed and only artificial light should be used to regulate the amount of light the peaches are exposed to so that the pictures of the colour of the peaches will be accurate.
4. I need to use photoshop to record their HSB values (Hue, Saturation, Brightness). This can be obtained by using a colour picker to pick a specific spot on the peaches.
5. The second part of the experiment is no longer necessary.
Anyway, here are the pictures of Part 2 since I have already conducted the experiment!
