Math
Today, we worked on “fractions of.” If your number is 21, 3/7 of that is 9. Take that problem and let me walk you through it. You know 7 goes into 21 equally 3 times so 1/7 equals 3. So 3 (the amount of 1/7)x3 (the number of sevenths) is 9 and there's your answer. We also had a unit 5 quiz. We needed to know how to make decimals into percents and percents into decimals. We also needed to know what every sector to a circle graph should add up to. That is 100%. I'm excited to see my grade. I hope it's an A+.

L.A.
Today, we chose our Nobel Peace Prize Winner that we'll be working on. I'm doing Kim Dae-jung because he won by his work for democracy and human rights in South Korea and East Asia. He was pretty related to MLK's way of winning. He won by fighting for human rights like Martin fought for negro rights. Those are the qualities I'm sure they're looking for in contestants.

Science
Today, we started (and finished) our lab on rocks. We tested to see which rocks bubbled when touched by vinegar. My study group was composed of Vraj, Zach, and me. The rocks we chose were Obsidian, Marble, Gneiss, Granite, and Limestone. Turns out only Limestone bubbles. This was an interesting lab. I got to wear safety goggles! The vinegar was just horrible. Although I didn't try, I could smell the vinegars stench. We also filled out a table of the rocks characteristics.
