5 min Egg squish Students are invited to try to break the egg by squeezing it length-wise with one hand. Someone willing to get dirty is invited to try squeezing the other way (easier to break). This is to give the students an idea of what orientation might provide the best protection for their eggs. 1 min Introduce the Tell the students that they will be designing and building an egg drop that we will test. Design Show which materials are available to use. Challenge 2 min First Prototype Give students 2 minutes to prototype the egg support system (i.e. the egg holder/protector) 5 min Test First Drop each student’s vestibule from the second floor balcony. Prototype Inspect each egg after the drop. In between the different ask students to predict what is going to happen and why. 15 min Second Give students 15 minutes to refine or rebuild their prototype. Prototype Give each student 2 eggs and them to test their prototype before the final test. 5 min Informal While cleaning up, continue to informally discuss what students learned about building, Discussion and what makes for better/ worse egg drops. Clean Up 3min Introduction to Introduce task and divide students along with the materials Ice Cream activity
