Today in class, we completed our first lab. We worked with oobleck for the experiment. The first thing we did before the experiment was we observed the properties of water. We then looked at the differences between solid and liquids. For the actual experiment, we tried to mix a solid and a liquid to see what the final state would be. I feel that the point of our first lab was to get warmed up. It was also so that we could get a feeling of how the actual labs will be further on the semester.
We were given a bowl of water at the beginning. Then corn starch started being poured into the water. At first, it was not solid and wet so we decided that it was a liquid. However, we continued mixing it more and it started to solidify. So we decided again that it was not liquid. It was a really interesting material to work with because it always looked wet but was actually solid.
At the end, I determined that this material was in fact solid. It is a hard material that breaks into pieces when slammed onto the table. I am guessing when the corn starch is put into the water, the two materials start to produce a "bond" or "something". When this "something" is produced, it becomes a solid object.
