Dissolving Eggshells Experiment
This awesome egg experiment is perfect for April! All you need are a few materials and a little patience (and possibly a strong nose haha) to get the experiment going. Your students will learn about chemical reactions, sensory input, and more as they are completely fascinated by what’s happening! As an added bonus, you can reuse the egg carton to plant seeds for another Spring or Earth Day activity, making this the perfect STEM activity this month. Check it out in action here:
Getting the Activity Started
Now that you know what dissolved eggshells look like, it’s your turn to complete the experiment with your preschool, kindergarten, or first-grade class. This can be a messy experiment with spilled vinegar or smashed eggs, so you can decide if you’d like to do it whole-group, with students observing, small-group, with one student in charge, or as individual experiments.
Materials to Dissolve the Shells
This experiment looks impressive but only needs a few items to pull it off. You’ll need white vinegar, eggs, and small dishes or cups to place the eggs in. That’s it!
A couple of notes:
- Make sure the containers are deep enough to cover the egg completely
- Place paper towels or a cookie sheet down in case of spilled vinegar
- Keep the door or windows open to help with the strong smell
Simple Steps and Patience for Spring STEM Activity for Kindergarten
Something that looks so AWESOME couldn’t possibly be easy, could it? It sure is! Here’s all it takes:
1. First, place a double layer of paper towels or cookie sheet down in case of a mess.
*Student Question Time* Using the free printable, you can have the students fill out the main question, “What happens to an egg in vinegar?” They can make their predictions before you begin.
2. Next, place a raw egg inside a plastic cup or bowl.
3. Then pour vinegar into the containers making sure the egg is completely covered. You can start talking about chemical reactions!
*Student Question Time* Ask the class, “Do you see the little bubbles forming around the egg What do you think is causing that?”
4. Now it’s time for a little bit of patience! It takes between 24-48 hours for the vinegar to dissolve the eggshells. Set your containers aside and check them occasionally.
5. You’ll know they’re ready to come out when a yellowish film covers the entire top of the container, and you can push on the egg and it feels squishy.
*Student Question Time* Ask the class, “What do you notice is different now than when we first put the eggs in the container?”
6. Take the eggs out and wipe them off with a damp paper towel to remove all the white film. Now it’s time for the fun part! Squeeze the egg to show your students how flexible they are without their eggshells! You can even bounce them on the table a little! *CAUTION* Don’t try to bounce them from too high like I did, or you’ll end up with a blooper and a big mess like this one:
