The lab involved testing the properties of Oobleck, a non-Newtonian fluid made from a mixture of cornstarch and water. The experiment aimed to determine whether Oobleck behaved as a solid or a liquid under different conditions.
The hypothesis stated that the Oobleck would exhibit fluid-like properties when pressure was applied slowly, but solid-like properties when pressure was applied quickly. The experiment involved placing the Oobleck mixture in a large container and testing it by pushing a hand into it slowly and quickly.
The results of the lab confirmed the hypothesis. When pressure was applied slowly, the Oobleck allowed the hand to sink in and exhibited liquid-like behavior. However, when pressure was applied quickly, the Oobleck became rigid and exhibited solid-like behavior, making it difficult to penetrate or move.
Therefore, the hypothesis was correct, as the Oobleck displayed distinct properties of both a liquid and a solid depending on the speed of the applied force.
To improve the experiment, it could have been beneficial to include more trials or variations in the application of pressure to ensure consistent results. Additionally, capturing the experiments on video could have provided clearer evidence of the Oobleck's behavior and allowed for more detailed analysis.
Write in short and like real people
In this lab, we tested this squishy stuff called Oobleck to figure out if it acts more like a liquid or a solid. We mixed cornstarch and water to make the Oobleck and then put it in a big container. We tried pushing our hands into it slowly and quickly to see how it would behave.
Our guess, or hypothesis, was that the Oobleck would act like a liquid when we applied slow pressure, but more like a solid when we applied fast pressure. And guess what? We were right!
When we pushed our hands into the Oobleck slowly, it was all squishy and allowed our hands to sink in. It acted just like a liquid. But when we tried to push our hands into it really fast, it became hard and tough to move. It acted just like a solid.
So yeah, our hypothesis was correct. The Oobleck can be both a liquid and a solid depending on how fast we push on it.
To make our experiment even better, we could have done more tries or tried different ways of applying pressure to make sure we got consistent results. Also, recording videos of our experiments would have been cool because we could watch them back and study the Oobleck's behavior in more detail.
