Dry Ice!

Playing with dry ice is always fun, and this experience was just that. (Of course you always need your safety gear.) We were able to watch a solid change into a gas. It's skipped the phase of a liquid! What we had to do was take dry ice and put it into water. After doing this we watched it dissolve into a gas. I took some bubble solution and made a bubble over the top of the bowl that the water and dry ice was in. That made the gas from the dry ice trapped underneath the bubble. Because it was trapped it slowly blew the bubble up and we watch the gas move around inside of it. They showed us that the gas takes up space, because it's matter.Then all of a sudden… Pop! We watched all the gas is excape into the classroom. Fun stuff!

Changing phases of matter: Jello!

All last week we looked at how cooling or heating things can change matter into solids, liquids or gases. Last week we looked at jello. First we looked at the powdered that makes jelly. We decided that Jell-O was a solid even though we can be bored easily and makes a heap which means that it's still a solid. Then we took it and we put it into boiling water we watched the powder dissolve. After dissolving it turned yellow. We place the yellow liquid into the freezer to let it cool. When we cooled it, it became a solid known as Jell-O. We touched it and felt it to find all the properties it had. Properties such as color, shape, texture, size, and temperature.

Then we took the Jell-O and put it back into a beaker and warmed it up with the hot plate. We found that the Jell-O turned back into a liquid just as it was before!
