5th Grade Science Projects

5th grade science projects can include seeing which brand of soda will decay a previously lost tooth the most. To do this experiment, you will need several different brands of soda, some teeth that you have lost recently, a few small dishes or cups, and a pen and paper to make a chart to record your findings.

I recommend these printable science project plans for K-12 for hundreds of great project blueprints and this step-by-step guide for doing an award winning science fair project. Also be sure to check out these fun science kits as a fast, simple way to get started on your science experiment.

Materials Needed:

Several different brands of soda
Some fallen out teeth (set a few teeth aside when they fall out rather than putting them under your pillow for the tooth fairy)
A few small dishes or cups
Chart to record your findings

Tooth Decay and Soda
Experiment: Which soda decays fallen out teeth the most?
Category: Chemistry
Ages: Elementary, Middle School

To begin, you can set up the various bowls or cups and place a tooth in each one. Next, add a different brand of pop to each bowl or cup. Be sure to label each one so you know what brand of pop is in it. Place them in an out-of-the-way place where they will not be disturbed and check them each day to see if there is any decay starting. Once you see some decay beginning, you can mark it on your chart and then see which one gets the most decay.
