My girls love Easter! They love all the pretty colors and they love the dyed boiled eggs. Okay they just like boiled eggs, adding the color makes them pretty to look at before they eat them.
While dying eggs my preschooler asked me what I was using and why couldn’t I just use regular hot water. So I decided to show her why, which leads to this preschool science experiment.
Our Science Experiment Tools
- Hard boiled eggs
- Small cups to hold eggs
- Food coloring
- 2 cups hot water
- 1/5 cup of hot vinegar
- 1 cup room temperature vinegar
- Add just the hot vinegar to one cup with some food coloring of your choice
- Add hot water to one cup and food color of your choice
- Add hot water and room temperature vinegar and food coloring to another cup 50:50 ratio
- Add water and vinegar and food coloring to another cup both room temperature 50:50 ratio
- Wait 2 minutes then check on them.
- After 5 minutes take out the eggs and discuss the results.
While doing this preschool science experiment I let my preschooler touch the outside of each cup. During this she was able to tell the difference between room temperature and hot. We talked a little more about ways to protect our hands when handling hot items. (Then the conversation led to Fire Safety which led to us talking about water and that led to movies. We got off subject !) We finally talked about which eggs, if any, would come out the colors that we choose and why.
We came to the conclusion that the heat really matters when coloring eggs, and that just plain water, whether hot or room temperature will only stain an egg. She thinks that we should leave the egg in the hot water longer next time.
After we ate the eggs and saved the shells for a project we noticed that the egg colored in hot water only still had its color two weeks later. The one done in vinegar and water still has their color the other two have lost their color or its starting to fade away more.
