Need an activity that is engaging, hands on, requires critical thinking and peer collaboration? THIS IS IT! This is a great lab that utilizes all of these and would be great for an observation! This lab will walk through the scientific method steps, research and analyze the properties of water and other liquids. Students can see how the molecules of each liquid will react with substances. Once the experiment is completed and the students have their results, they collaborate with two other groups and record their results to compare. This eliminates having to do the experiment more than once, although I do emphasize that in an experiment, results need to be able to be repeated for it to be considered proven.

This can be used as an introductory lab for water properties for older students.
