For five days, we observed the changes in three boiled eggs that were kept in different liquids (variables) - coffee, vinegar and Coca Cola.
MACKAYLA 'S BLOG POST -
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!
This week, we decided to look for new strategies to add and subtract five digit numbers. Students selected their own strategies from a list offered to them, and inquired into it.
Once they had taught themselves the new strategy, they applied it to solve problems.
Now that they were experts, it was time to teach the strategy to some one.....and learn a new one!
SHABIYA: I taught Victoria adding by BREAKING NUMBERS APART strategy and she taught me about splitting. She understands very well this strategy because her strategy is also about place value.
ANNISAA: I taught Evangelina how to break apart numbers into place value. She understand it well and I make her try to do 1 million, She got it right!
KEITARO: I taught David the Jump Number Line. I can understand the strategy easily. Jump number line can be used to add and subtract numbers. Its best for small numbers - you can make jumps of ten. But in bigger numbers we should make jumps of 100 or a 1000.
EVANGELINA: I taught Annisaa adding by Compensation Method and she understands it well. Annisaa taught me how to break numbers apart into place value. It was easy for me because I feel that I am very good at place value.
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.
