The hypothesis is that aluminum foil will be more effective in keeping the bottle of water cold for a longer period of time.

You will need to drill holes in 3 corks, fill 3 conical flasks with the same amount of ice water, insert thermometers into the corks, wrap one flask in aluminum foil, wrap another flask in plastic wrap, and leave the third flask unwrapped.

You will need 3 conical flasks, 3 corks, an electric drill with appropriate sized bits, 3 thermometers, 1 roll of aluminum foil, 1 roll of plastic wrap, 1 bottle of ice water, 1 measuring cylinder, and 1 clock.

The experiment showed that the water in the conical flask wrapped with aluminum foil remained the coldest throughout the experiment. This proves that aluminum foil is the best insulator for keeping water cold.

This science project is interesting because it shows how different materials can be used to insulate and keep things cold or hot.

Try repeating the experiment using different wrapping materials like bubble wrap or wax paper. You can also repeat the experiment using hot water and observing the rate at which hot water cools in containers wrapped with aluminum foil and plastic wrap.
