Students collected data on how often we should brush our teeth daily, and recorded their responses. Then, we researched healthy teeth and revisited our data. We concluded that we should be brushing our teeth at least 2-3 times each day.
We discussed how to keep our teeth clean using a toothbrush and toothpaste during a classroom experiment. We learned that if you don't use toothpaste when brushing you may leave behind bacteria that could lead to staining our teeth.
We really enjoy experiments in first grade!
