Hot or Cold?

DRY ICE!!!! It's so cold that it burns when you hold it for any length of time. We put it in soppy water and bubbles just started erupting, almost like a volcano except the lava was the bubbles. Once the bubbles popped it didn't become liquid, but dispersed into that white mist you sometimes see during a rock band concert. Then we put the dry ice into a tank and blew bubbles over it. As the bubbles floated down, right before it reached the bottom, it floated up in mid air, kind of bounced up and down and then just hung there, floating in the air, not moving up or down. It was so cool! :) Another thing we did was put the dry ice in a big basin filled with water and liquid soap. We used a cloth and ran it on top of the bowl like a cover and a big bubble that covered the entire opening of the container was formed. The gas from the ic began to expand the soap buble and the buble began to creep over the sides of the basin so that it looked like a giant mushroom or domw. Then it popped and all of a sudden theres was all this mist in the air and a whole bunch of laughter. ^_^

Powers of Ten

I suggest everyone watch the powers of ten video because it's so cool! :P it goes from a picture of a man on a picnic and every ten seconds, the window expands all the way up to the 10 to the power of 26. At this point, we are way past our own milky way and into the universe where you can see other galaxies that look like tiny far away starts. Then we zoom all the way into the 10th to the -16th power. We get all the way into the nucleus of an atom that is one of billions that make up our body's DNA. We also watched the Simpson version too and that was pretty cool because they showed the aliens :)

The Periodic Table

The periodic table. It's looks intimidating at first, but once you get to know its properties and the way it is put together. Trying to put together our own periodic table really helped me o understand it better and also understand where each element is placed and why. In some places there were elements that dont seem to belong there and I wonder why it was put there. I think the organization of the table is great though because reading left to right, the atomic mass increases, and top to bottom, the number of spokes, or varseles, increase. Working on the Periodic table has somewhat allowed me to grasp the concept of the elements better, and hopefully as the year goes on, I can improve even more.

Elements and Compounds Lab

Playing with first is always fun, but it was even cooler when we put the steel wool in the flame of the candle. Sparks flew and at the end, there were silverish blue balls that had formed on the steel wool.
