The Jell-O Experiment
Materials:
· Jell-O powder
· water
· gummy fish
· cups
Problem/Question:
What happens when you add hot water to Jell-O powder and put the mixture in the fridge?
Hypothesis/Prediction: I think the Jell-O powder mixture will turn from liquid to solid.
Procedure (what we did):
First, we stirred the hot water into the Jell-O powder until the powder was dissolved. Then we poured in cold water and stirred again. Next, we poured the Jell-O mixture into cups. Then, we put the cups in the refrigerator for 90 minutes. Last, we added fish into the squishy Jell-O, and we refrigerated again.
Observations/Data (what we noticed/what happened):
We noticed that the Jell-O was solid when we took it out of the refrigerator the next day.
Results/Conclusion (answer your question):
The Jell-O powder was solid, tiny little crystals. It turned to a liquid mixture when we added hot water and cold water. The hot water was steaming. Steam is a gas. When we refrigerated the mixture it turned to solid. We were right!

The Ice Shape Experiment
Materials:
· water
· measuring cup
· containers of different shapes
Problem/Question:
Does the shape of ice affect the speed it melts?
Hypothesis/Prediction:
We think the tiny cup will melt first.
Procedure (what we did):
Put the measured water in the cups. We used 2 tablespoons for each cup. Freeze it. See how they melt.
Observations/Data (what we noticed/what happened): The one with the most air is melting first. The largest looking bowl melted first. The cup melted second, and the ice cube melted last.
Results/Conclusion (answer your question):
We were wrong about the tiny cup. We think it didn't melt first even though it looks smaller, because it didn't have as much air touching the ice. The air is warm.

The Frozen Egg Experiment
Materials:
· 2 eggs
· cups to hold eggs
Problem/Question:
Does an egg change after freezing and thawing?
Hypothesis/Prediction:
We think the egg will look different. Maybe it will change colors. Maybe it will be spotted.
Procedure (what we did):
Put the egg into a cup and then put it in the freezer. Wait until the next morning and take it out. Wait until it thaws. See if the one that froze is different from one that didn't. Look at the egg and write down changes.
Observations/Data (what we noticed/what happened):
The egg white is yellow and the membrane was stuck to the shell. The yolk looked like a ball, like a cooked egg. The yolk and white do not mix now.
Results/Conclusion (answer your question):
The white changed color from clear to yellow. The yolk did not change color. The yolk turned into a ball like it was cooked. There were no spots.
