In Science during our Week 2 and Week 3 Newsletters we have been learning all about Matter. I have been so excited for this lab — and I know the kids were excited also. On Thursday we learned about Physical and Chemical Reactions … Which led us perfectly into our Lab Day on Friday!!

The picture at the top was of all of our Diet Coke and Mentos — and the geyser tube that Mrs. Tinch was so kind to let us borrow. I already have one of my very own ordered from Amazon!! This gadget made our experiment fantastic!! If you would like to order your own, the link is here.
This is our video of the Diet Coke and Mentos experiment. Note my gracefulness getting out of the spray! One of my kiddos said I was like the Matrix with my moves. Ha!! 🙂

The picture at the bottom was of one of our 2 lab tables that were set up for our Exploding Baggie Experiment. Each class was divided into 4 to 5 groups. Each group had to place 1 and 1/2 tablespoons onto a small piece of paper towel then fold it into a little packet. Then students measured 1/2 cup of water and 1/4 cup of vinegar and put these both into a small sandwich bag. Afterward, we went outside and placed our small paper towel into our bag. We had to carefully shake it and zip our bag up all the way. Students threw them onto the ground, and waited for the pop of the bag. What happened was the baking soda and the vinegar had a chemical reaction and built up a gas. The gas would fill the bag – then the bag would pop open. This lab was a tad disappointing to some — if the instructions weren’t followed to a T, and if the bag wasn’t sealed all the way then the bag didn’t pop. I’m including the links to these labs from Pinterest, and I’m also going to include a lab that I’m curious about. It may be in the plans for next year 🙂
The link for the Exploding Baggies is here.
The link for our Diet Coke and Mentos experiment is here. After we completed the experiment, I found out from an “expert” that the Sam’s Choice Diet Coke is the best to use for the experiment. I will try that out next time!!
The link to the lab that I’m curious about is located here. If I had a balloon – I would be testing it out right now!! 🙂
