Objective
By the end of this lesson, you will be able to turn an egg shell transparent using a combination of energy drink, coke, white wine vinegar, baking soda, and salt.
Materials and Prep
Materials needed:
- Energy drink
- Coke
- White wine vinegar
- Baking soda
- Salt
- Egg
Things to know before the lesson: Make sure to have adult supervision when handling certain materials.
Activities
Start by carefully removing the egg from its shell and placing the shell in a bowl. Rinse the shell with water and let it dry.
Prepare different solutions using the energy drink, coke, white wine vinegar, baking soda, and salt. Place each solution in a separate container.
Submerge the egg shell in each solution for a specific period of time and observe any changes that occur.
Compare the transparency of the egg shell after being exposed to each solution. Note down your observations and any differences you see.
Talking Points
"The acidic nature of the solutions reacts with the calcium carbonate in the egg shell, causing it to become transparent."
"The energy drink and coke contain phosphoric acid which helps dissolve the shell."
"White wine vinegar is a mild acid that can also break down the shell."
"Baking soda and salt can be used to neutralize the acidity of the solutions after the experiment."
