Over three days we did 3 science rotations. The three science rotations that we did last week were baking, cooking and paper mache. The science rotations were lessons on the states of matter. For baking, the state of matter was, what is the difference if you put butter that is solid or if the butter is a liquid. For cooking we turned a liquid into a solid, the questions were does ice make a liquid to a solid. For paper mache, we made a liquid/flour + water a solid.
On the first day of the science rotations I did baking, for baking we baked cookies. We made two sets of cookies one with solid butter and one with liquid butter. My hypothesis was that the set with solid butter would become hard and crunchy and the set with soft butter would become soft and would rise. My hypothesis was wrong instead the solid butter cookies were very soft and the liquid butter cookies were crunchy.

For cooking we made something that was a liquid and then became a solid, we made ice cream. My hypothesis was that when we were mixing the liquid in the ice it would have become ice cream and taken much longer than 20 minutes. I also thought that I would be runny. My hypothesis was wrong, we shook the bag of ice cream inside the bag for 20 minutes and the ice cream became ice cream. Instead of the ice cream being runny it was soft and good, I think it tasted exactly like ice cream from a store.

Paper mache was a really fun experience and we also learned a lot. In paper mache we learned about how flour and water become gluten, flour + water is what we use in paper mache to stick the paper together. My hypothesis was that I think that the flour and water will stick the paper together. My hypothesis was right the next day when we checked our paper mache they all looked good, I peeled off the tin foil and bowl under the paper mache and the paper mache did not collapse. There was only one thing that did not go right since we used flour and water instead of glue it tarted to mold because if you think about it if you leave gluten overnight it will start to mould.
- Get a bowl
- Get tinfoil
- Rap the tinfoil around the bowl
- Mix water and flour together
- Rip up paper
- Spray something so the paper won’t stick to the tin foil
- Put the piece of paper in the cup of flour and water
- Take two fingers and scrape off extra
- Make sure your bowl is upside down and then lay the paper on the tin foil
- Repeat until the bowl has a couple of layers
- Drie overnight
- In the morning take of the tin foil and bowl
