True Story! I was a witness to a “Controlled Experiment”. I went to the allergy doctor , and his doctor performed the experiment on me! I was the control factor, the Histamine shot was the control group, and the other 40 shots were the experimental groups. The doctor compared the 40 shots with the control shot (histamine) to see what I was allergic to. It was awesome! Bell Work: 9/9/13 • Imagine that you are on an airplane over the ocean. What would be the worst thing that could go wrong in that situation?
Objectives • SPI 0707.T/E.1 Identify the tools and procedures needed to test the design features of a prototype. • SPI 0707.T/E.2 Evaluate a protocol to determine if the engineering design process was successfully applied. • SPI 0707.T/E.3 Distinguish between the intended benefits and the unintended consequences of a new technology. • SPI 0707.T/E.4 Differentiate between adaptive and assistive engineered products (e.g., food, biofuels, medicines, integrated pest management).
Scenario: • Your school field trip to New Zealand to see where The Lord of the Rings movies were filmed has taken a turn for the worse! Your initial travel from your school to the Nashville International Airport was fine. Your flight from Nashville to New Zealand started off as scheduled. The plane was on course until a severe thunderstorm caused both the engine and the radio to fail. The plan was forced to crash somewhere in the South Pacific. The plane was torn to shreds, but the emergency raft remained intact. You and your classmates climbed into the raft and drifted on the ocean for several hours. You finally washed ashore on what seemed to be a deserted island as a…

A STORM IS APPROACHING!!! • Hurricane Coltharp is quickly approaching, so you and your teammates will need to think fast! You need to design and construct a shelter that can withstand strong winds, keep out rain, and hold all of your team members.
A STORM IS APPROACHING!!! Engineering Criteria: • Sturdy- given three heavy gusts of wind, the shelter must not move, tip over, or be damaged in any way. • Water Resistant- Given three squirts of water to simulate rain, the inside of the shelter must remain completely dry. • Spacious- Each member of your team must fit inside of the shelter.
Engineering Constraints: Actual Materials on the Island: Materials for building the shelter model: • Logs (20 logs per team) • Strip of plane siding that washed ashore (1 piece) • Tarp from the rescue raft (1 piece) • Rope that washed ashore • Mud • People • Craft sticks (20 per team) • Aluminum foil (1 piece) • Wax paper (1 piece) • String • Play-Doh • 3-dimensional graph paper cube
Engineering Design Process: • Ask • What shelter design will keep water out, stand up to strong winds, and hold all group members? • Research- use your prior knowledge to research about shelters or houses • Imagine • Brainstorm ideas and come up with a hypothesis that describes the type of shelter that will survive a storm. • Plan • Use the Survivor Digest on the front cover of the instructions. • Make a materials list of the items that you will use to build the shelter. • Draw a blueprint of your shelter design. • Building steps • Create • Collect all materials and build your model according to the design you chose. • Test your shelter against the storm. • Improve • How can you change or improve our design?
