Greenbrook Cycle 2- Engineering

During this cycle, students learned a great deal about Engineering, focusing on the Engineering Design Process.  Students had the opportunity to take on the role of a structural engineer with a challenge titled Waterproof that Roof! As a group, we brainstormed real-life connections and discussed the need for sturdy, waterproof structures that can withstand extreme weather.  We also did a bit of research on roof pitch and construction. Students have begun to understand the need for gutter systems, and the difference between absorbent and repellent materials. 
Aside from learning about roof design and construction, students faced real-life constraints including material choices, budget, and time. They followed the steps of the Engineering Design Process to complete their work. 

Daniel, Anish, and Timur created a waterproof roof using cardboard, masking tape, straws, and cotton balls. Their design shows the thought they put into a gutter system, which was successful. In a redesign, this group would remove the cotton balls, as they hold onto water.

Anika and Aadya constructed their roof using pipe cleaners, popsicle sticks, and cotton balls. They realized that although the cotton balls could absorb water, they would need additional materials to truly waterproof the roof. In a redesign, the girls would add aluminum foil and masking tape.

Ciana, Ria, and Zara constructed a successful waterproof roof using cardboard, aluminum foil, and masking tape. They were sure to leave sufficient overhang so that water would be carried away from the structure. In a redesign, this group would add a gutter system.

Armaan and Tafzil constructed their waterproof roof using cardboard, masking tape, cotton balls, and straws. Their pitch and gutter system allowed water to be carried away from their structure. In a redesign, the boys would cover all sides of the roof to ensure a completely waterproof structure.
