The hardest energy to find was sound energy. We were looking and looking, but we couldn't find a second one, until someone had the idea to take a picture of me playing the recorder. Then we found the third one pretty easy after that. Our group worked together by talking to each other and taking turns using the camera. The collaberation that happened was we talked about what we should take pictures of and compromised. The chalenges were getting all the pictures we needed in the time we had.
