Today we went to the computer lab to use the virtual lab in the previous post. We were measuring the viscosity of different fluids, water,honey, olive oil, ethanol, and corn syrup. Then we changed the temperature we used: Low 14 Celsius, medium 55 Celsius, and the high 70 Celsius. Then we dropped a steel ball to test the viscosity. Below are the results.
Water: 14 Celsius low viscosity, 55 Celsius high viscosity, 70 Celsius high viscosity
Honey:14 Celsius low viscosity, 55 Celsius low viscosity, 70 Celsius high viscosity
Olive Oil: 14 Celsius low viscosity, 55 Celsius low viscosity, 70 Celsius high viscosity
Ethanol: 14 Celsius high viscosity, 55 Celsius high viscosity, 70 Celsius high viscosity
Corn Syrup:14 Celsius low viscosity, 55 Celsius high viscosity, 70 Celsius high viscosity
As a class we asked a question and it was does the temperature affect the viscosity. By the results we got we found out that yes the temperature does affect the viscosity. My hypothesis was yes the temperature does affect the temperature, and my partner (Emma) got the same hypothesis.
If I did this experiment in real life do I need these exact things? I don't have steel balls, only like bouncy balls and stuff.

You probably need something of the same buoyancy, weight, shape to get the same results.

Steven, did you get a choice between a virtual option vs an in-person lab? Do you have a science lab for Junior High students at your school? I'm just wondering if you HAD to do a virtual lab or did you have the option of doing a real-life version?
ReplyDeleteThank you for the detailed report!
Yes we do have a science lab, but we had to use the virtual lab because we didn't have the ingredients or the time, or the proper equipment to do this. The science lab we have can be used by any grade in our school.
