Today is officially group 4 project day, and we're off to a very good start.
We have assembled all our apparatus (three trials in all). We changed our idea slightly in that instead of using three different materials, we're now using the same material (saran wrap) and three different light sources (fluorescent, incandescent and natural sunlight, though probably not today because it's a bit cloudy).
We have recorded the starting time of each trial and measured each initial salinity also. This is very exciting!
We'll blog again later in the day when we check our experiments.
