Grade 3 students, can you explain the process of sublimation? Use these pictures to help yourself remember the process and leave your thoughts in the comment section.
Last week Grade 3 experimented with Coke and Mentos. 3SS students used their DoInk skills to create animations of the chemical reaction. Enjoy!
Making Fizzy Drinks On Wednesday 17 of April, 3SS made Fizzy Drinks, and it looked so good when we started to make it. We poured orange juice in it and we also put sugar powder. We made the Fizzy Drinks independently and when everyone was finished mixing the sugar powder and the Fizz powder together, Ms. Skrtic came around the tables, again, to give us orange juice to pour in the sugar powder and the Fizz powder. But you don’t need to pour everything in the cup. When Ms. Skrtic gave the orange juice, we mixed it , Ms. Skrtic said we had to mix very well. When we where done mixing the Fizzy drink, we tasted it, but not every experiment needs to taste, but this one, you would be glad to taste it, because it taste HORRIBLE! it was salty. Then few minutes later, some people came up with freezing it, and then lots of people wanted to freeze there’s. It seriously taste salty. The next day, we took a look at our frozen weird taste fizzy drink, when we tasted it again, it still taste horrible. We threw it in the bin and went to the bathroom to clean our hands and clean their mouth so they take that weird salty taste out of their tongue. Most of us decided to never make that weird drink again. - Sofie

Yesterday we did another experiment on which liquid evaporates faster, alcohol or water. We taped a pencil on the cup, then we dipped one strip of paper towel in water and another in alcohol. We carefully put the wet paper towels on the edge of the ruler and balanced it on the pencil. After we waited for a while the alcohol evaporated faster and the paper towel was nearly dry. - Sarina
The experiment we did yesterday was alcohol vs. water in evaporating. I liked working with my partner and I also liked looking, smelling and touching. My favorite part was when the ruler fell down because the alcohol had evaporated first. - Mark
Today in class we did some Chocolate Crispies. When we were finished making it we ate it. There are 8 steps of how to make it. We used some materials to make it. We decided how solid can turn into liquid. The solid can turn into liquid by melting. And liquid can turn into gas by evaporating.
Thanks to a great inquiry question from a visitor to our blog, 3SS decided to find out what would happen if we placed another egg in coke instead of vinegar, which was an experiment we conducted a few weeks ago that you can revisit here. We kept the egg in the coke for about 5 days. We predicted that the same thing would happen to the egg since coke is an acidic drink. We found the color of the egg changed, just like the color of your teeth would change after drinking a lot of coke.
First in our egg and vinegar experiment we put the egg in a bowl and then we poured the vinegar and left it for 4 days. Then we looked at it and the shell became softer and softer and the shell floated away. In this experiment we found out that the egg shell is like a tooth. If we put acidic things on our tooth the same thing will happen to our tooth. So drink less acidic drinks and more water.
This past week, 3SS conducted an experiment with an egg and vinegar. The short video below demonstrates part of our set up. Thanks to Ryan for doing the filming! Why do you think 3SS would conduct such an experiment and what do you think will happen? Remember we are currently in the middle of our Unit of Inquiry on Making Healthy Choices. Check back in the next few days when a Student Blogger explains what happened.
