Reflection: Adjustments to Practice The Great Liquid Race-Viscosity - Section 3: Explore



In doing the liquid race, I had to make some adjustment. I had to create a higher incline plane to make the ketchup flow due to the fluid being so thick. When I increased the incline plane, the ketchup flowed better.

The students enjoyed it and they had the opportunity to observe liquids. The students noticed that much thinner liquids ran very quickly and thicker fluids ran slowly. Students were able to make a connection about what viscosity means. A thicker fluid restricts how it flows.  This concept is important because students need to realize that scientists create liquids in various capacities to use as needed.

The Great Liquid Race-Viscosity

Unit 9: Learning About Matter
Lesson 7 of 9

Objective: SWBAT observe the properties of liquids by investigate the flow of liquids during a a liquid race.

Big Idea: It is annoying to get to the end of the ketchup bottom and you have to bang on the table to get the last bit of ketchup. Ketchup is thick and it does not flow like thinner liquids. Why?
