How does science work? Learn about the 9 skills of science (observation, making inferences, predicting, estimating......). Involve your students in some of these skills. This lesson will take an entire day with the activities that are included. Involve your students in observation activities using different senses. An estimation activity is included also. Hypothesize as a group to solve a problem. I like this power point because of the involvement with the activities. They will look at their senses in a new way!
