Crystal experiments 1/31/16

This week I started to discover crystals. The Experiments we were doing were all about trying to discover the unknown crystal. On the piece of paper we had salt, sugar, MSG, and Epsom salt. I was looking at all of the different crystals and trying to find differences and similarities. Salt and sugar both looked like little cubes. Then, I was given an unknown crystal and was trying to figure out what it was. It looked a lot like Epsom salt, But it only had clear crystals. Epsom had clear and white crystals. It couldn't be MSG because MSG was like tiny little shreds. Salt and sugar were much to small to be the unknown crystal. Then, instead of observing them, we crushed them to see if that was another way to find out. The Epsom and the unknown both were crushed into a fine powder, but were still different colors. Will we ever find the identity of the unknown?

S&EP: SP4:Analyzing and interpreting data
I used a worksheet to keep track of my data. We had several different worksheets to draw my data upon. I had a lot of data.

Summary: This week I learned about cold and warm fronts, why the warm air rises, and about high and low pressure systems. If there is a high pressure system and a warm front, you can expect a clear, sunny day. If there is a low pressure system and a cold front you can expect a cold cloudy ( possibly rainy) day.

SP4: Analyzing and interpreting data

This week we were doing an activity where we would gather data from a website. Like if the sheet said to turn on the drifting balloon setting and then watch the balloon move throughout the day, you would do it. If it said gather the wind direction and temperatures on the four corners of the screen, you would do it.
