Save the Boulders Beach Penguins by Sarah Sedlacek https://padlet.com/sedlsara/sap7f0dzt08y By: Sarah Sedlacek en-us 2018-02-12 16:53:30 UTC 2025-05-10 00:36:15 UTC hello@padlet.com Step 1: Identify the problem sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/230697239 These penguins need to be saved because they are overheating in S. Africa and there eggs are getting stolen by birds.
How can I design and build a shelter that reduces heat transfer and keeps my ice cube penguin from melting?]]> 2018-02-12 16:58:31 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/230697239 Step 2: Research the problem sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/230697748               Insulators
1)White Foam
2)Aluminum
3)Mylar]]> 2018-02-12 16:59:19 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/230697748 Step 3: Brainstorm possible solutions sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/230698142 Trays Demo: We would NOT want conductors. We would want to use insulators.
Spoons Demo: We do NOT want to use metal as the floor in the home
Black vs Mylar Roof:
We are going to use a roof material that is reflective, so it can reflect the heat.
Attic vs Floor: We do not want our penguin to be near the top of our house because it will be exposed to more heat.

Aluminum for roof and walls. White foam for insulation, and Mylar on top for extra protection.]]> 2018-02-12 17:00:52 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/230698739 Step 5: Construct a porototype sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/230699191 2018-02-12 17:01:42 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/230699191 Step 6: Test Prototype sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/232412328 My successes in my groups design was the percent lost wasn't to much greater than 30%. The percent loss was 38%
But a failure my groups design had was the house was a bit to small because when the ice cube melted it started to melt outside of the house.]]> 2018-02-16 16:46:27 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/232412328 Step 7: Modify design to improve it sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/232413847 A change we made was the  floor. Our floor used to be construction paper but we changed it to white foam because we thought it would help absorb heat away from the penguin ice cube. 
We also added Mylar for our roof to help reflect more heat away.]]> 2018-02-16 16:49:43 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/232413847 Step 8: Present and resign if needed sedlsara https://padlet.com/sedlsara/sap7f0dzt08y/wish/232414341 The changes we made is we added more insulation in the roof, changed the floor, and added Mylar on top. All of these changes succeeded. Our failure was the floor but when we changed it, it improved. The final percent loss was 30.3%! If I could make one more change it would be to make it bigger.]]> 2018-02-16 16:50:56 UTC https://padlet.com/sedlsara/sap7f0dzt08y/wish/232414341
