Kitchen Chemists Egg-speriments: The Bouncy Egg

Course Summary

Neurodivergent friendly! Turn ordinary eggs into bouncy science! Over two days, students will observe how vinegar reacts with eggshells, turning them into flexible eggs without a shell. Predict, experiment, and have some fun with chemistry!

Course Description

In Eggs-periments: The Bouncy Egg Lab, students explore chemical reactions using one of the most familiar ingredients in the kitchen: the egg. On day one, students will make predictions and set up their eggs in vinegar to see the shell dissolve over time. On day two, they will observe the transformation, explore the egg’s new flexible membrane, and test how it behaves in fun, hands-on ways. This course teaches basic chemistry concepts like acid-base reactions, physical vs chemical changes, and structure and strength. It encourages prediction, careful observation, and discussion.

Syllabus

Day 1: Egg Setup & Reaction Start Predict what will happen when eggs meet vinegar Place eggs in cups/jars and cover with vinegar Observe bubbles forming (reaction of acid on calcium carbonate) Record predictions & observations Wrap up: set eggs aside to soak overnight Day 2: Observe & Explore Examine eggs after soaking (shell dissolved, membrane intact) Observe texture, flexibility, and bounce Optional tests: gently bounce, roll, or measure size Discuss what happened chemically: vinegar (acid) + eggshell (calcium carbonate) → gas + membrane

Supplies

Raw eggs (1 per student) Small clear cups or jars (1 per egg) White vinegar Spoon Paper towels Optional: small weights or straws for bouncing/testing
