Today in class we calculated the density of the gold bar and found that it was not gold Oh well Mr. Krabs will not be rich. We also calculated that if the bar was gold, it would need to weigh almost twice what it does. In addition we found that if the bar would be worth $508,800 using the current price of gold at $636 per ounce. After that we packed our suitcase and found that stuffing more thing in it, while keeping the volume the same increases the objects density. Next we looked at some video clips about aerogel and how it was used in the Stardust mission to catch pieces of a comet. Aerogel is the least dense solid we know of. It's 99.9% air. They describe aerogel as a glass sponge. I have a small piece of aerogel for students to look at. Finally we went over the upcoming density lab for Thursday and Friday. Students were informed of the safety cautions and we went over each page of the lab.

Calculating Volume Practice (Blue WS)
The homework for Thursday November 16, 2006 is to compete the Calculating Volume practice paper. It will be collected on Friday. This paper will help student review for the Volume quiz on Friday. Students can also prepare for the Volume quiz using my study guide page below. About half way down the page, are about four or five links that will help student review for the quiz.
Today in class I collected the Volume review paper.
Today in class we grew a dinosaur (period one), pirate (period 2), dog (period three) and we will grow a cat or teacher or brain in periods five and six. Students also practiced calculating volumes by using a math formula and by water displacement. We also looked at why 50 ml of water and 50 ml of rubbing alcohol don't add up to 100 ml of liquid. This has to do with the miscibility of fluids. We took 500 ml of wild rice (yikes) and mixed it with 500 ml of rigatoni and we got about 700 ml total. The molecules of alcohol are smaller than the molecules of water and they can fall between the water molecules just like the rice can fall between the rigatoni.

Review Independent Dependent Variables Quiz Monday
Sorry for the last two days. I have not been able to use the internet at school. Without prior warning the server was removed, which left me in the lurch on Thursday and Friday. The server was taken from the school to be backed up and replaced. Fro some teacher this would have little effect, but I use my website daily in class and the resources such as BrainPop are integrated into every lesson each day. Each day at lunch I upload a new homework message. I had created several pages to help my students review for the dependent and independent variable quiz on Monday and was unable to use them in class on Thursday or Friday.
The homework on Thursday night was a practice worksheet on finding volume. I collected that on Friday. The Homework for Friday was to review and prepare for the Experimental design quiz on Monday. The quiz will cover controls, variables, independent and dependent variables, control group and constants. My study guide pages below will help students prepare.

Those that did not finish the questions should do so this weekend and have it ready for Monday. Most of period six was used to take a class picture on Thursday so they are a little behind the other classes.
They tell me the server will be back sometime next week but it will be removed again when the new one comes in. Sorry for the disruption but I'm the last to know and the most effected, along with my students. Be prepared for intermittent service over the next few weeks.
