Well, after many technology issue and tears (from me), most of our toothpaste commercials are complete! Why toothpaste commercials, you may wonder? Well, besides being interesting and engaging, it was a great opportunity to teach many skills. First, we experimented with commercial toothpastes. We used the scientific method to test the PH levels, starch levels, and abrasiveness of various toothpastes. Students also learned skills such as advertising techniques, writing skills, public speaking skills, and teamwork. This unit also gave my students the opportunity to learn to use new technology such as video cameras and video editing software. Here are some of our final products! Enjoy!
