To make a problem, ask a question. For example: What will happen when you soak an egg in vinegar? Now that we have a question, let's get started!
Step 1: Hypothesis
Step 2: What You Will Need: Prepare for the Experiment
For this experiment, you will need:
- A container that you don't mind getting dirty
- A raw egg
Step 3: Fill the Container: Set Up Your Experiment
Step 4: Submerge the Egg and Wait: Conduct Your Experiment
Step 5: Have Fun Playing With Your Egg: Observe
After the 24 hours (or your desired amount of time), you can take out the egg. If there is still some shell on it, you can carefully scrub it off with warm water. Then it should look like how it is depicted below. Now have fun bouncing and squishing your egg. You can also hold a light up to it for a cool glowing effect.
****WARNING**** If you bounce your egg from too high or are too rough with it, it WILL break. Even though it may feel kind of solid, it is still, um, eggy on the inside.
Step 6: Conclude
The vinegar contains acetic acid, which eats away the carbon and calcium molecules in the eggshell. The membrane, however is left undisturbed because it doesn't contain materials that the acid can attack. The bubbles you saw were carbon dioxide being released.
Thanks, everyone for viewing my Instructable. I hope you had fun making a jiggly, bouncy egg while learning how to use the scientific method!
