Rea told me that the former scientists of the day have brought in things for the rest of the class to interact with or manipulate. For example, one student's project included Root Beer floats. Yum.
We thought it'd be a great idea for each student to get a plane. Rea flat out refused the idea of making paper airplanes - She said the boys go too crazy with paper airplanes. So I went shopping in search of something appropriate.
