Photo and Basic Info

Throughout our eight weeks of solar car–curtesy to Karen Metcalf, who put together this whole thing–we worked on our solar car! During this time, we have built, broke, and rebuilt to create what we have now. Our theme is Lightning McQueen, and our goals for it is the be exceptionally light. This goal was semi met, as we think we could have made it lighter. During the sprint a new member was added, as our sister and friend. She did solar car last year as well and was a big help to us.
