To wrap up our exploration of solids, students were asked to collaborate
 with a partner for the construction of towers. Students acted as 
engineers to use what they learned about the properties of solids to construct towers.  We began by reviewing what a tower is and by brainstorming 
different objects that stand up on their own.  Students worked with 
straws, rubber bands, craft sticks, aluminum foil, cardboard squares, 
and paper cups.  We ended our science lesson with discussion of the 
different towers students created, with focus on which properties were 
useful for this project and which objects properties were not useful.
