This activity has learners observe water and compare it to other liquids. They stir and scoop the liquids, drip them onto various materials, drop various objects into the liquids, and record what they see using the provided worksheets. While the materials list is quite long, many of the items can either be omitted or substituted with other things, since the investigations themselves are fairly open-ended. There is also a "Science @ Home!" activity on page 7 of the Student Journal for students to investigate their home water usage.
