As part of our Dental Health Unit students will become little scientist to discover what happens to our teeth when we eat different types of food/drinks. Students will conduct the experiment and document their discoveries along the way. There "EGGsperiment" will be displayed on a display board, two file folders glued together. Here is a sample of what the display will look like.
To begin the EGGspirement students will be told that we are going to use an egg as a pretend tooth and we will talk about why an egg makes a good tooth substitute (outer shell is like the enamel of our tooth). We will then brainstorm different types of food/juices that might stain or have an affect on our teeth. Each "team" (a group of 4 students) will choose which food/drink they would like to complete the experiment with. They will then write their question ex: Is soda bad for teeth? or Will soda stain my teeth? Each students will write their own hypothesis in step 2 ex: Mark thinks that soda is bad for teeth and can stain them. Sarah thinks that soda is good for teeth and will not stain them etc... Students will then get a hard boiled egg (1/team) and a cup with the liquid of their choice (1/team). Students will submerse their egg in the liquid overnight. The next day students will document their findings and attempt to clean their egg by brushing it with a toothbrush and toothpaste. (Don't forget to take a picture of this for the display board) Students will put their egg back into their liquid for one more night and return tomorrow to document their experiment. As a team, students will write a conclusion to their experiment detailing their findings.
(I will have one group choose to experiment with vinegar. The kids are amazed by what happens with this liquid!)
