Use this lesson to teach how to make a good observation. TSW add the first handout to their science journal. TTW pass out a chocolate chip cookie to each student in a ziploc along with the first observation page. Mark the ziplocs in a way that you will know which belongs to each kiddo. TSW draw their cookie. TTW will need to act a little bit to create some sort of reason why you need to collect all cookies in their ziplocs. Once the drama is over attempt to pass the cookies back out but...how on earth will you figure out which one belongs to each student? Ask the students to see if their drawings will help. Uh oh they all say the same thing! Pass the cookies out to their rightful owner. This is why scientists are super specific. Add the second handout to their science journals. Try it again.
