One of the groups measuring out one of their walls |
As this school year was winding down, we fourth grade teachers wanted to give our students a project that would bond them together as a group as they head into middle school next year. We had already divided them into nine groups for their 5th grade placements in the fall, so we decided to use those groups, without letting them know they were working with next year's classmates. For the past few years, we had been kicking around the idea of having the students build pneumatic geometric structures, using only 500 sq. ft. of neoprene and several rolls of duct tape for construction. They needed a fan of some sort to inflate their structure once it was completed. Another criteria was that the structure had to be large enough for their entire group to fit inside simultaneously and read once construction was complete.

Hmm, this is our ceiling. Will we all fit inside? |
The groups had to first work together to come up with a geometric shape and then with graph paper, they had to create a scale model. This demonstrated their math skills as they had to determine square footage of all the sides and also figure out how much tape they would use on the edges. Then they had to wrestle with the idea of the volume of air inside their proposed structure and decide if the fan they had would be enough to inflate it. This was such a great activity for them to HAVE to work together and work on their math skills, comunication skills, small motor skills for drawing and cutting and then the most difficult part of all, was the actual construction of their structure. Our only input was to answer direct questions that showed that they had struggled with the issue and were at an impasse. Also, if a group was arguing too much, (we told them a little arguing is good for learning and cooperation), or if group members were goofing around, the team would be penalized with the loss of 50 sq. ft. of neoprene for each incident. We didn't have to penalize any team!

They didn't think they could do it, but they learned something about themselves! |

Brian gives his opinion on the project through a vent hole he made!
All in all, this was an unbelievable project for our fourth graders to take on. They were hard-working, creative, and they never gave up. If something wasn't working, they would simply try something else. The only time a teacher had to actually help was with the taping for a group that had designed a structure with curved sides. That took the entire group, working together, as well as the teacher to get the taping done and the structure inflated! After all the structures were completed, every class in the entire school came down two at a time to wander through our new village and go inside and have a fourth grader read a story to them. I think we have a new tradition for the end of the school year for all students in our building to look forward to. Some will be building the pneumatic structures and most will be experiencing them and sitting in them, perhaps planning for when it is his/her turn?
