What You'll Need:
- Glass jar with lid
- Get started by boiling the egg and letting it cool.
- Invite your child to place the hard-boiled egg in a small glass jar. Discuss with your child how the egg is no longer raw, but that through heating, the egg is now solid, changing its original matter.
- Now your child can pour plain vinegar over the egg and cover with a lid or a piece of plastic wrap. Position the jar in a location where your tot can come back and observe the changes the egg goes through.
- Allow the egg to sit in the vinegar for three days. The vinegar interacts the the calcium carbonate, changing the composition of the egg shell and the hard-boiled egg.
- After three days, remove the egg and gently rinse with water. Check out the changes the egg has gone through and invite your tot to give it a gentle bounce on the counter. The acid from the vinegar interacts with the calcium carbonate, causing the changes to the egg and creating an incredible bouncing hard-boiled egg.
