Change Experiments


Butter
We did an experiment where we turned cream into butter. We poured cream into a container and took turns at shaking the container. First the cream turned into whipped cream and then into butter.
At first the fat was spread throughout the cream and we couldn’t see it. When we shook the container the fat particles all came together. We got to try the butter on bread with some different spreads. It was yummy.

Lemon Juice
We wrote messages with lemon juice. We could not see our messages until we ironed our paper.
The Lemon juice had acid in it. It made the paper weak. When we ironed the paper the heat made the acid left on the paper turn brown. We could then see our message.

Eggs
We put eggs into water, orange juice, coke and vinegar.
After a week nothing had happened to the egg in water.
The shell of the egg in the orange juice went bumpy.
The shell of the egg in coke went dark brown.
The egg in vinegar had the most changes.
The acid in the vinegar dissolved the shell. It separated the calcium and the carbonate that make up an egg shell.
The egg also got a lot bigger.
