This lesson is appropriate for any science classroom. It doesn't matter if you teach Biology, Chemistry, Physics, Psychology, Ecology, Environmental Science, Physical Science. It is great for ANY teacher that wants to explore these usually boring topics in an interactive way. This activity contains 8 pages of lesson plan instructions, handouts and activities! I actually use this segment for my evaluations when my administrator needs to come and visit. It contains everything you need to score high! Included in this lesson: 2 days of bellwork, 1 exit slip, 2 sets of student worksheets (one on observation vs. inference, one on bias), and a set of scenario cards, and a photo for the observation activity. When I do this lesson 100% of my students are engaged and time flies in the class!
