Brief Description PREMISE:
The HMSS Endurance just shipwrecked 100 miles from Antarctica. Sir Shackleton and his crew (the class) are stranded and must engineer essential survival needs from items they have on their boat.

SCENARIO: In order to survive, the crew recognizes the need for water before anything else (shelter, food) can be built. Their matches sunk with the ship, so the crew cannot build a fire to melt ice for drinking. The crew finds a bucket of dirty water in the galley wreckage, but it is filled with oil, rice, tea, and other nondrinkable materials. The deck captain finds a medicine kit with cloth, medical tape, cotton balls, eye droppers, sticks, and a few other items.

ENGINEERING: The crew must design a solution using these materials to create clean, drinkable water.
ENGINEERING DESIGN PROCESS CHALLENGE: sketch a plan before the team receives materials or builds anything.

Learning Goals: Students learn about water filtration, water quality, and teamwork in the context of “Shipwrecked at the Bottom of the World” by Jennifer Armstrong

Based off of Detective – Environmental Engineering

Materials: Materials:

- Classroom presentation about scenario, engineering design process, and discussion of importance of clean water
– Rinsed plastic bottles to hold dirty water
– Dirty water: mixture of sand, rice oil, glitter, tea, etc

Materials per group:
– 3 plastic cups (1 will hold dirty water)
-Square of cheese cloth
-1 ft duct tape
-Handful of cotton balls
-Length of string
-3 sheets printer paper
-1-2 sheets thicker paper
-3-4 popsicle sticks
-1 mL plastic pipette or eye dropper

Preparation: -Mix dirty water ahead of time
-Divide materials into bags for each group
-Arrange students in groups of 3
Knowledge Background 1. Design scenario in context of Shipwrecked 2. Discuss importance of water quality with students
Procedure 1. Students discussed the importance of clean water and health.

2. Class was presented with Shipwrecked scenario and design challenge

3. In groups, students sketched a plan for their water filter design.

4. Students worked in groups with the materials provided to design and test their water filter.

5. STOMPers rotated around classroom, prompting questions to guide discussion and reflection about results.

6. Last 10 minutes of class, each group took turns sharing their designs, successes, and challenges.
