Students becoming scientists.
Our students at Marshville are very fortunate to have teachers taking an active role in teaching them scientific facts and principles. In our first grade classes the students have been studying the properties of solids, liquids and gases. The students have learned attributes of each of them throughout the unit. In an effort to make the unit even more interesting, each day from Monday-Friday the students were able to witness a very interesting activity that was taught by one of the first grade teachers.
On Monday, Mrs. Honeycutt showed the students an experiment that amazed them all. She placed bottle caps on 4 eggs and then placed a very large cinderblock on top of the eggs. Believe it or not, the eggs did not break. She then placed several large dictionaries on top of the cinderblock and it still did not break.
On Tuesday, Mrs. Honeycutt preformed an activity where she placed powdered Alka-Seltzer and water inside of a small film canister. When an Alka-Seltzer and water are mixed, it creates a gas inside the container which causes the top to blow off like a rocket. Sadly, this experiment was not a success. It was okay that it did not work because the children were then able to use their scientific knowledge to hypothesize what went wrong.
On Wednesday, Mrs. Jarman did an experiment where she immersed a cup that had a piece of paper towel in the bottom into water. She was able to explain to the students why the paper towel did not get wet even though the cup went into the water. Mrs. Honeycutt also redid her experiment with the Alka-Seltzer and it worked. We concluded that the type of Alka-Seltzer makes a difference in whether the gas will be activated and how fast. On Tuesday, Mrs. Honeycutt used a powder Alka-Seltzer and on Wednesday, she used the solid tablet.
On Thursday, Mrs. Fox did several experiments. She discussed the fact that two types of matter canâ€™t be in the same place at the same time. She took two water bottles and sealed them together with hard clay. One bottle had water in it and the other was empty. She showed the students how the water would stay in its original container even when it is turned upside down. She also did an oil and water activity. Lastly she did a sink and float activity with several items with which the kids were familiar.
On Friday, Ms. Middleton talked to the students about mixing a solid and a liquid could generate a gas. A Winter Mint Mentos was placed in a liter of Coke, and boy what an explosion! The students were amazed at what happened. The Winter Mint Mentos activated the carbonation in the Coke and caused it to create a gas. The gas then had no place to go once it filled the bottle and caused a waterfall of Coke.
This was a great week for the kids. The students had an opportunity to make predictions and rethink several reasons why some experiments ended the way that they did. We had a blast!
