Solids, Liquids, and Gases: Learning about the Phases of Matter

Next, we are starting with Liquids and did a fun experiment to see how Viscous different liquids are. First, we learned what viscous meant after discussing what the properties of liquids are. Viscousity is how sticky a liquid is, and the slower it flows, the more viscous it is! The faster a liquid flows, the more fluid it is. 

 We tested: shampoo, water, glue, and oil! First we made our predictions, then we put the liquid on a plate, and turned the plate upright to see how many seconds it took for the liquid to reach the bottom of the plate! We predicted that the order of liquids from the most fluid to the most viscous would be the following: water, oil, shampoo, glue. Then, we tested the liquids:

We realized that the order of liquids from the most fluid to the most viscous is: water, oil, glue, shampoo. We couldn't believe the shampoo was more viscous than the glue! This helped us see just how important it is to test, and that there is always something more to learn! We then also discussed that if we had a different type of shampoo, the results could be different as well. We love experimenting in the S.T.R.E.A.M. Lab!
