Is your Experiment 8th Grade Science Project Ready?
Try this for your 8th grade middle school
experiment.
WHAT Beverages stain your teeth the most?
Call a local dentist to ask if you can get
some teeth from them. (Of course already washed and
sanitized,
You should set your question for your science
project and determine now which beverage will stain teeth the
most in the same amount of time.
Get together 4 glasses. In one glass
place coffee in another place grape juice (the purple colored
stuff - not white grade juice!). In the 3rd glass place
tomato juice and in the last use a soda pop.
Now put a tooth in each glass and let it sit
overnight.
The next morning drain each liquid and remove
each tooth to a paper towel. Pat each one dry and place
them next to each other for observation. Note any
discolorations either blotchy coloring or full staining.
Which beverage was worse for the teeth?
Did any clean them better than they were when you started the
experiment.
You can even ask your dentist if it is
possible to cut the teeth in half to see how far the staining
may have gone into the teeth from a side view.
Make sure to graph your findings.
See High School Science Project for an
experiment using these same type of teeth to see which product
cleans them better
