Well a while ago I promised to have Azia and Jaxom guest blog to show off their science projects.. well I have been a bit busy. I have been helping put something together that my loom knitting friends will love.. ahh you have to wait till tommorrow! So Here is Azia’s report!
Eggciting Science: bouncing eggs!
I found out that if I soaked eggs in vinegar they would bounce so I decided to make my experiment about that!
Problem:If I dropped four eggs that have been soaked in vinegar for different amounts of time from the same heights which egg will bounce the most before breaking?
Hypothesis: The egg that is soaked in the vinegar longest will bounce the most before breaking because it was in the vinegar the longest.
Method: I will soak three eggs in vinegar for 2, 4 and 6 days then I will drop each of the eggs from various heights and see how many times each egg bounces before it breaks. Result…

Egg |
Dropped from 9 inches | Dropped from 36 inches | Dropped from 6 feet | Dropped from 12 feet |
| 2 Day Egg | 3x no damage | 3x no damage | 3x no damage | 3x no damage |
| 4 Day Egg | 3x no damage | 3x no damage | 3x no damage | Membrane broke on second drop |
| 6 Day Egg | 3x no damage | 3x no damage | 3x no damage | Egg broke on second drop |
My experiment was to see if I dropped three eggs that have been soaked in vinegar for different amounts of time from the same heights which egg will bounce the most before breaking? I thought that the egg that was in the vinegar longest would be strongest because it was in the vinegar the longest. I decided this because I thought that the vinegar would make the egg stronger, and so it wouldn’t break when I dropped it. I placed three hard boiled eggs in glasses filled with vinegar.
The first egg was in the vinegar for 6 days, the second egg was in the vinegar for 4 days and the third egg was in the vinegar for 2 days. I did some research and found out that the vinegar would make the egg shell dissolve because there is a chemical reaction between the vinegar and the calcium in the egg shell. After soaking the eggs in the vinegar, I took them out and dropped them from various heights.
My results are in this chart.

Egg |
Dropped from 9 inches | Dropped from 36 inches | Dropped from 6 feet | Dropped from 12 feet |
| 2 Day Egg | 3x no damage | 3x no damage | 3x no damage | 3x no damage |
| 4 Day Egg | 3x no damage | 3x no damage | 3x no damage | Membrane broke on second drop |
| 6 Day Egg | 3x no damage | 3x no damage | 3x no damage | Egg broke on second drop |
My hypothesis was wrong because the egg that was soaked in the vinegar for two days never broke; the egg that was in for six days broke at the highest height. I think it’s because all of the shell did not dissolve on the two day egg and because all of the shell dissolved on the 6 day egg.
Stay tuned for some exciting news tommorrow!! Well if you late owls check in you might catch it before everyone else!
