Today Mrs. Hahn's class earned extra science time. They chose to do some rocket fun. The first one that they watched was a tea bag "rocket". We took a tea bag and cut of the string and emptied out the tea. That left us with a cylinder of light weight paper. We lit the paper and watched what would happened. You can watch the video below. The flame created by burning the tea bag heated the air inside the cylinder. This made the air less dense and it rose above the cooler, more dense air. When the tea bag burned it left behind ash that was light enough that it did not need much force to lift it. It also had so little mass that it floated back down slowly. Then we took it out side. After much fixing, we finally got the water bottle rocket launcher working. We talked about how the air pressure was built up by the bicycle pump and it wanted to be released. By releasing the ring that held the bottle on to the launcher, the air pushed the bottle several yards into the air. Bonus, the kids got to see me and Will get soaking wet from the last rocket.

Today Ms.Lemmon's class got to enjoy extra science lab time for behaving well for the last quarter. Their class chose to see what happens when you add Mentos to soda. We also wanted to see if there was a difference between using a mint Mentos and a fruit flavored one. Once we decided that the mint Mentos did the best job, we wanted to find out what soda created the largest reaction. This one, I will keep secret and let you find out. Above is the soda that made the largest reaction and below is the soda with the smallest reaction. And just for fun, we wanted to see what 5 Mentos would look like in the secret soda. I came across this video on Sunday morning and I could not resist posting it. To say it is on the ridiculous side is an understatement, but I love me some NASA! I know this is not an exciting post, but the easiest way to log information for the staff meeting. I decided to use a Webcounter for my Weebly to help decided what best to spend my time doing. Here is the web site I used: But it is easy enough to google for free counters. I have one on my home page and on another page.
In regards to the Weebly. Super Easy. I have really found it helpful in finding safe sites for student internet research. I even dragged my laptop with me when I took a fifth grade class to the Media Computer lab. While they were doing research and needing another site or could not find information, I would locate a new website and then publish a new button. Super easy and keeps the kids from Googling anything not appropreate by accident. Opening wide for a little something sweet. This quarter Kindergarten is learning more about the 5 senses! This week we were discovering more about the sense of taste. 5 different kids (everyone got a chance) came up and were blind folded. They had to open their mouth up like a little bird to get ready to taste something either Salty, Sweet or (wait for it......) SOUR! Some of our brave friends were subjected to a small piece of lemon to experience sour. Then everyone was able to taste some. What brave folks! After tasting we then brainstormed other things that tasted sweet, salty and sour. |
