Science Class
In Mrs. Demers science class we are doing a lot of fun science labs. The labs are based on chemical changes. For our last class we got a balloon full of 2 scoops of baking soda. Then we filled up a plastic water bottle with 18 scoops of vinegar. When we were ready we put the balloon on the bottle. Then we dumped the baking soda in the vinegar. After that the vinegar got all bubley and the balloon started to blow up. The balloon got really big, we thought it was going to pop but it didn’t. At the end the vinegar wasn’t bubbly anymore. But at the bottom of the bottle was some weird white paste. The paste was called “sodium acetate” and is evidence of a chemical change. The gas bubbles are evidence of a chemical change too. We do a lot of fun science labs in Mrs.Demers class. This was only one of them.
