The viscosity of most liquids is effected by temperature.
To test this we experimented with corn syrup… |
|
 |
One way to test the viscosity of a liquid is to drop something
into it and see how long it takes to sink… |

This experiment focuses on the viscosity of shampoo in a bottle as it is heated and cooled… |
|
 |
Different liquids have different properties. Some are thin and flow more easily than thicker, more viscous liquids… |
