For five days, we observed the changes in three boiled eggs that were kept in different liquids (variables) - coffee, vinegar and Coca Cola.

This week I really enjoyed doing the egg experiment! Ms. Batlaw set up a cup of vinegar, coke and coffee. On Monday, Ms. Batlaw put hard a boiled egg in the vinegar, coke, and coffee. Starting from Tuesday, we observed what would happen to the egg. I noticed that the egg in the coke cracked. The egg in the vinegar’s shell dissolved into the vinegar. The egg in the coffee didn’t get affected at all.
One of my questions was, will the egg in the vinegar be able to bounce? The answer is yes! Evangelina tested it out, and it actually BOUNCED! We were all very surprised. The reason I had a question like that was because Shabiya shared with us that someone told her the egg in the vinegar would bounce.
I wasn’t expecting the egg in the coke to crack. On Friday, we checked the eggs. The egg in the coke is cracking everywhere! I bet it thinks it’s cracking up a good joke! But now it’s cracking too much. For some reason, there is white powder on the top of the egg, which is on the surface.
As I said before, the coffee isn’t affecting the egg. We are not too sure why. The only difference is that there are now 6 dead flies floating around. That probably means that flies like the smell of coffee. The egg in the vinegar’s shell dissolved into some sort of brown peelie thing. The brown thing feels really weird and slimy. EEW! Uck. It stuck to my hand once.
Well, that's what happened this week, for the EGG EXPERIMENT! Grade 5 is going on really well to me!
View life from the lens of a 10 year old, and it will bring much humour and joy. That sums up my experience with my grade 5 students at ISS.
