The sixth graders have started an engineering unit. We will be exploring the design process as the kids work through engineering challenges. We started the unit with a simple tower that had to be built out of 20 straws and a foot of masking tape. Then the kids had to make bridges out of five index cards. The bridges had to be strong enough to hold 100 pennies. I think the strongest bridge held over 200!
The third challenge was to develop a package for a s'more. Each group was given $15 science dollars and had to purchase their supplies. The package was then dropped from 2 meters, submerged under water for 30 seconds, and heated with a heat gun for 45 seconds. It was then unwrapped to see if it survived. Unfortunately, many of the s'mores were a little soggy...
