Save the Penguins! by Ann Hepp https://padlet.com/heppann/bt8lvs03meiw Created by Ann Hepp en-us 2018-02-08 18:43:59 UTC 2026-02-25 04:48:54 UTC hello@padlet.com Step 1 - Identify the Problem heppann https://padlet.com/heppann/bt8lvs03meiw/wish/229754230 Penguins are overheating in the arctic because of climate change, and we want to help them stay cool. How can we help them stay cool?]]> 2018-02-08 18:46:18 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/229754230 Step 2 - Research the Problem heppann https://padlet.com/heppann/bt8lvs03meiw/wish/229754940 2018-02-08 18:47:29 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/229754940 Step 3 - Brainstorm Solutions heppann https://padlet.com/heppann/bt8lvs03meiw/wish/229755732 We thought about making an igloo to keep the penguins cool . We're using our research to incorporate the feathers and other insulator materials into our design and solution. ]]> 2018-02-08 18:48:46 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/229755732 Step 4 - Select a Solution heppann https://padlet.com/heppann/bt8lvs03meiw/wish/229756122 We chose to make an igloo- we decided to make the walls out of tin foil and the ceiling out of mylar since it's reflective, made the floor out of bubble wrap, and decided to put feathers and cotton inside.

It was challenging to get the penguin in and out of the house though, so if we ever repeated the test we would probably try to make that easier. We only lost 5 percent of the penguin. ]]> 2018-02-08 18:52:32 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/229757961 We put in our igloo with the penguin in under three heat lamps for 20 minutes to see how much it melted heppann https://padlet.com/heppann/bt8lvs03meiw/wish/232082390 we lost around 28 percent of the penguin, and we realized that our design was pretty good but decided that we wanted to make the shape of the walls a little different.]]> 2018-02-15 18:46:02 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/232082390 We looked up more about the penguins and what might help them stay cool, and then tested materials to see which were the best insulators heppann https://padlet.com/heppann/bt8lvs03meiw/wish/232083240
We found that feathers, bubble wrap, and cotton were the best insulators. ]]> 2018-02-15 18:47:19 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/232083240 heppann https://padlet.com/heppann/bt8lvs03meiw/wish/235499831 2018-02-26 17:27:58 UTC https://padlet.com/heppann/bt8lvs03meiw/wish/235499831
