Gobstopper+Lab

=Gobstopper Observation Lab= =Problem:= What happens when four different colored gobstoppers are placed in water? =Hypothesis:= I think that the colors of the gobstoppers will mix and all of the water will turn a different color. =Materials:= One petri dish, four gobstoppers, and enough water to cover the gobstoppers. =Procedure:= 1. Put four different Gobstoppers in a container of water and color in the first diagram to show these colors. 2. Observe the Gobstoppers and water. Then color in the first diagram to show the first color change in water. 3. Each time the Gobstoppers and the water change color, go to the next diagram and use colors to show what you see. =Observations:=
