    Program Description
    3 hour program
    1 class (32 students)
    Students will work as engineering design teams to create a path for water to flow down the wall without any leaks. Each team will design the path on a paper grid that is a scale model of the wall. Working with constraints including limited and unfamiliar materials, time and a budget, teams will purchase materials from their allotted budget and use a spreadsheet to do their calculations. Students will work cooperatively to build their prototype using the materials purchased. Teams will test and revise as needed. Teams’ success will be based on meeting the criteria of each challenge.

    Performance Expectation 

    3-5-ETS1-1 Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.

    3-5-ETS1-2 Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.

    3-5-ETS1-3 Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
