Easter 3 Egg STEM Challenge
How to Make Marbled Easter Eggs
- Fill your baking sheet with shaving or whipped cream until it's about an inch thick, then smooth it out with a rubber spatula.
- Drip food coloring onto the cream. Don't be afraid to be generous with the colors — the more you use, the brighter your eggs will be.
- Use a toothpick to swirl and marble your food coloring droplets.
- Pick up a hard-boiled egg — put on rubber gloves first! — and roll it in the cream, coating it completely.
- Carefully place the egg onto a paper towel and let it dry for about 20 minutes.
- Wipe the remaining cream off with a clean paper towel to reveal your colorful marbled pattern.
Friendly reminder: If you plan to eat the dyed eggs, use whipped cream.
Your mission—if you choose to accept it—is to construct a parachute that will deliver an egg safely to the ground when dropped. No fancy materials allowed! You can only use familiar household items like plastic bags and string. Do you think you have what it takes to construct this gravity-defying wonder? Be careful: a sloppy parachute will result in a yolky mess!
The Raw Egg in Vinegar Experiment
Take a raw egg and place it in a jar or other container deep enough to submerge it the egg completely in liquid. Pour vinegar over the egg until it is covered. You will see bubbles forming on the egg's shell. Cover the jar and place it in the refrigerator for 24 hours. Carefully remove the egg from the jar using a a hard spoon and replace the vinegar in the jar. Place the egg back in the jar and cover it again. Put the jar back in the refrigerator, and wait another 24 hours. Take the egg out and rinse well. You will have a translucent egg with no shell, just a thin membrane.
The Hard-Boiled Egg in Vinegar Experiment
The egg in vinegar experiment can also be done with a hard-boiled egg. Boil an egg for 10-12 minutes until it is hard-boiled. Place the egg in a jar, cover it with vinegar, and cover the jar. Place in the refrigerator for 24 hours, then replace the vinegar. Let the egg sit in the new vinegar solution in the covered jar for at least 24 hours (may take a few days). After you take the egg out and rinse it off, you will find that the shell is dissolved, and that your egg bounces.
