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
SPORTS
RELATED SCIENCE PROJECT
You can test to see if eating a power bar with lots
of protein or a power bar with lots of carbohydrates is more
effective at giving you more energy to complete an athletic
event.
First you probably want to use the
same person to test this theory because some people have more
stamina than others.
Plan to get up the next three
mornings and exercise for a bit. Only do this if you are
in good shape and exercise all the time. If you are not I
would not do it because it could cause injuries if you are not
stretched or are not use to exercise on a regular basis.
If you, however, exercise every
morning and want to test this try the first morning when you get
up eat a power bar that has more protein in it. Do your
normal exercise routine and see if you are able to exercise for
a longer period or at a faster pace.
The next morning eat a power bar
that has more carbohydrates in it and do the same. You do
your normal exercise routine and see if you are able to exercise
longer or faster.
The final day get up but don't eat
anything and do your normal exercise.
Did any of the books allow you to
feel like you has more energy or stamina. Did the day when
you did not have any nourishment before you exercised make you
stop exercising early?
For your future athletic events did you
determine which bar would be best for you? Maybe one
worked at giving you a lot of power early but provided no long
term energy power. Maybe one provided for a long lasting
even allowance of energy.
