Our design challenge today was a WATERCRAFT challenge.  We watched two quick videos .

Then they were given the challenge of building a boat out of straws and plastic wrap that could hold 25 pennies for at least 10 seconds before sinking.  They used the following Design Squad instructions.

Check out our boats. Here is our first team to complete the challenge. Congratulations.

It was really neat to hear some of their ideas about how to redesign in their 1st attempt did not work.  Things I heard was to make the boat heavier so it would displace more water.  I also heard to make the boat more in a v shape so it would displace more water.  There was some deep thinking going on in the redesign process.  Some worked and some did not but they were coming up with a way to fix it right away.  Great Job!!!
