Students experimented by dissolving a chicken bullion cube in different temperatures of water. Their manipulated (independent) variable was the different temperatures of hot water in each cup. The responding (dependent) variable was how long it took the cube to dissolve. The result was that the hottest water dissolved the cube the quickest. Students concluded that hot water makes the molecules of solids move quicker and the hotter the water, the faster the dissolving.
I hope you enjoy learning how the garden changes throughout the school year.
