One of my classes that I teach is life science. These are some of my student's cell projects...they just amazed me. One of the requirements was they do these without parent help(except if they had to get supplies.). I encouraged them to use what they had...one of them made a cake cell, one used toothpaste in her project, my own daughter made a duct tape cell. All but one of the projects were for sure student done...one of them, I don't know for sure. The questions about why the student made the grade they did tipped me off to maybe some special interest from a parent involved in the project. But, I could be wrong!!!
