Science Project:

Soda and Teeth

3.7 based on 205 ratings

Materials:

  • 3 cans of different carbonated soft drinks
  • Water
  • 4 plastic cups
  • Masking tape
  • Pen
  • Scissors
  • 1 cup granulated limestone
  • 4 pH strips
  • Scale
  • 4 coffee filters
  • Measuring cups
  • Newspapers

Procedure

  1. Gather the necessary materials.
  2. Label three of the cups each with one of the different names of soft drinks being used. Label the fourth cup “Water.”
  3. Pour ½ cup of each of the soft drinks and the water into the appropriate cup.
  4. Test the pH of each of the liquids using pH strips. Record the information.
  5. Label the coffee filters with the four different liquids.
  6. Pour ¼ cup of granulated limestone into a coffee filter. Weigh the filter with the limestone. Record the weight.
  7. Put the appropriate coffee filter with ¼ cup limestone in the appropriate cup.
  8. Pour ¼ cup of the appropriate liquid in each cup.
  9. Set the cups in a safe place overnight.
  10. The next day, remove the filters of limestone from each cup and set them on some newspapers to dry completely. The drying process may take a couple of days.
  11. When the filters of limestone are complete dry, weigh each one again and record the weights.
  12. Subtract the final weight from the starting weight for each filter of limestone. Compare the weight of limestone to the pH levels to each of the liquids.
