16 Amazing Science Experiments with Eggs to Sneak Education

Are your backyard chickens going gangbusters with egg production? Summer is a great time to bust out the eggs and learn a little science!

We’ve done quite a few of these projects already but I’m always shocked to learn about all the amazing things you can do with eggs. Check out this awesome list of science activities that all ages of kids (and adults too) will enjoy!

These 16 egg experiments are fun to anytime of the year, but they’re great for summer learning, as summer boredom busters, or even during the spring – think Easter egg-citement!

Our favorite easy science experiment using eggs is the naked egg experiment. Using items you probably already have at home, it’s easy to make a shell-less egg your kids can touch and hold. And the best part about this experiment is that it’s to easy, anyone can do it!

The Naked Egg Experiment

Did you know that backyard chickens sometimes lay eggs without shells? It’s true. We don’t find then on our homestead all that often, but occasionally we do.

Naked Egg Experiment Supplies:

To do the naked egg experiment, you only need three things:

  • an egg
  • wide mouth glass or a jar
  • plain white vinegar

How to do the Naked Egg Experiment:

Day 1: Have your kids carefully put an egg in the jar and pour enough vinegar in the jar to completely cover the egg. You should notice that little gas bubbles (carbon dioxide) appear right away in the jar. Place the jar in safe spot and leave it alone for 24 hours.

If more than one child wants to do this experiment, I recommend giving each child their own egg and jar.

Day 2: The next day, take a look at the jar. You should see a foamy scum like substance in the jar. This is eggshell dissolving! Very carefully, pour the old vinegar out. You might want to take the egg out of the jar to see how soft it is and compare it to how it felt the day before. Put the egg back in the jar and pour fresh vinegar to cover. One more, place the jar in safe spot and leave it alone for 24 more hours.

Day 3: After 48 hours, the eggshell should be dissolved! Carefully pour off the vinegar and take out the egg. If the eggshell is gone, you’re done! If it’s not quite dissolved, cover it with fresh vinegar again and check on it one more time. Be careful with this naked egg! It’s very easy to break.

You’ve now created your own naked egg – just like the eggs you sometimes find in the chicken coop! How cool is that?

The Science Behind the Naked Egg Experiment:

Why does this happen? Well, eggshells are made of calcium carbonate and vinegar is an acid. When the acid in the vinegar comes into contact with the eggs, it dissolves the calcium carbonate – leaving only the egg covered in a thin membrane behind.

  1. I love science experiments that the kids and I can do together. Thanks for so many great ideas just in time for Easter!

  2. Our chickens are giving us lots of eggs right now, so this post inspires me to bring them to the school room for some science fun. These activities look awesome!

  3. I love this list. We’ve been doing some experiments with eggs and you’ve got a few here that we haven’t done yet. We should really try the walking on egg experiment!
