Dental Health FREEBIE!!!

Friday, December 30, 2011

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!)
