Year 5 used the current sunny weather to their advantage and carried out an evaporation investigation this week. We left 200ml of water in different containers and left them outside for 2 days. We then collected them in and independently measured what was left of the water after 2 days of evaporation. We discovered that the best container to avoid evaporation was the 2lt pop bottle as the sun had less surface area of the water available to heat the water molecules. Also, the water that did evaporate, turned into condensation on the walls of the bottle, avoiding escape!
