Description
In this activity, students mix several sugar solutions to investigate the property of density. Each sugar solution has a different density and color of the rainbow. The less dense sugar solutions will be able to float on top of the more dense solutions, and the variation in color will allow students to create a rainbow inside of a drinking straw. The students will then consider what items will sink or float, and make inferences about their densities based on the results of their experiments. Students can extend their learning using one of the Extensions provided: The students can try to identify the density of an unknown solution of sugar water using the known densities of the solutions they made.
