Exciting Experiment!

Density filled our classroom! On October 12th, we did an experiment in science that had to do with the viscosity and density of a substance. Viscosity is a measure of how strongly a gas or liquid resists flowing.

My teacher handed out some mustard, ketchup, sunscreen, shampoo, food coloring, soap, and other supplies for this experiment. We arranged the mustard, ketchup, etc., from the least dense to the most dense on a scale from 1-8.

To test the viscosity, we used the food coloring and a toothpick to demonstrate surface tension. We poked a bubble of food coloring with a toothpick with soap on the end, then with nothing on the end. We had to observe what happened.

In my opinion, this was a very neat and fun way to learn about density and surface tension!
