eggs with solution for a kids' dental health experiment

This fun dental health science experiment will use eggs to emphasize the effects of different beverage choices on our teeth to your kids. If you have a hard time getting your child to brush their teeth, this concept will help to teach them the importance of brushing.

From preschool and beyond, this activity will surely be a hit when it comes to encouraging your children to take great care of their teeth from this point forward.

 

The Egg Scrubbing Science Experiment

Before you begin the experiment, start by talking to your child about what good oral hygiene habits look like, and how important it is to brush their teeth every day. Explain how certain foods, drinks, and activities can leave teeth with stains and damage. It’s also a great time to discuss how drinking acidic beverages can erode the outside of the teeth, specifically referring to the enamel.

Create a hypothesis and ask your child to come up with a few types of drinks that they think might be harmful to their teeth, and what kind of drinks are best for their teeth.

Step 1: Gather Your Materials

This simple experiment doesn’t require a lot of expensive supplies, making it cost-effective on many levels. In fact, you will likely have most of the materials already in your home.

The materials you will need to complete this dental health teeth experiment include:

  • 1 cup of soda or soft drink (a brown soda such as root beer or cola)
  • 1 cup of vinegar
  • 5 plastic cups or jars
  • 1 cup of fruit juice (lemonade, orange juice or apple juice)
  • 1 cup of water
  • 1-4 toothbrushes
  • Baking soda or toothpaste
  • 4 hard-boiled eggs
  • Paper towel
  • 4 egg holders, optional

Step 2: Start the Experiment

  1. Start by first hard-boiling your eggs to prevent any drops of accidents.
  2. Once cooled, let your child place the hard-boiled eggs into the plastic cups or jars.
  3. Allow your child to begin pouring the different liquids over the egg until they are completely submerged.
  4. Create an index card or chart that is color-coated to show which liquids are in which containers.  This will help everyone in remembering which liquid was in which container as the experiment progresses.
  5. Leave the plastic cups and plates to soak overnight.

Tip: If you leave the eggs soaking in the liquid for too long, the egg shells may start to dissolve. While this may be a great experiment in itself, it’s not what you want to focus upon for this experiment.

Step 3: Observe and Explore

Ask your child to check the eggs the next day. You may need to pour the liquid out of the cup to see how each egg has been affected. Most likely, the egg in the cola has been stained by the liquid overnight. One at a time, remove the eggs from the liquid and place it in an egg holder. Encourage your child to observe and discuss what the liquids have done to each egg and how the colors of the shells now vary.

Encouraging Great Oral Health With Your Findings

Set up the toothbrushes, water, and toothpaste or baking soda. Give your child a toothbrush and water first, and begin to scrub the shell of the egg. You will likely discover that dark-colored liquids are unable to be removed from the shell without the use of toothpaste or baking soda.

 

Things To Take Away From This Experiment

There are two main things you want your child to take away from this type of experiment.

ONE. The citric and phosphoric acid contained in soda has significant potential to erode tooth enamel. In fact, findings show that soda is 10 times more erosive than fruit juice in the first few minutes after drinking it.

TWO. The second takeaway, and the more obvious takeaway to your child, is that it takes more than just a few quick swipes of the toothbrush to clean their teeth properly. Set up a two-minute timer while your child brushes the egg to represent the time they should be taking to brush their teeth twice a day.
