What Happened to the Egg?
Kentucky’s Early Childhood Standards
3 and 4 year olds Science
Standard 1: Demonstrates scientific ways of thinking and working (with wonder and curiosity)
Benchmark 1.1: Explores features of environment through manipulation
Vocabulary: feathers, flight, beak, egg Materials: uncooked egg, white vinegar, clear jar, marker, chart paper
- Wash egg with soap and water. Pass the egg around for the children to feel. – Remind them the egg is uncooked and to be very careful or the shell will crack!
- Ask them to describe the shell--how it feels, smells, looks, etc.
- Place the egg in the clear jar.
- Cover the egg with vinegar.
- Have the children predict what will happen to the egg in the vinegar. Chart their answers.
- Place the jar where the children can see it but instruct them to not touch or move the jar.
- In about 24 hours, you will be able to see through the egg (the vinegar will disintegrate the eggshell) and you will be able to pick up the egg.
- Allow the children to feel the egg. How does it feel now? Remind them to be careful. The egg will pop if squeezed too much.
- Review the predictions of what the children thought would happen to the egg. Did any of the children predict correctly?
