Hard to believe we have completed 4 weeks of chemistry. Great work guys!! I hope you are amazed at the intricacy with which our Heavenly Father made the earth. To think of the exactness of each atom and how they work together and make up everything around us. We should stand amazed and in awe of His awesome creation!!
HOMEWORK:
Monday: Complete pg 27 Suds Duds experiment (sent home plaster of paris)
Tuesday: Silly Putty-with the silly putty we made in class or some you have at home perform the following and record your results. (If your putty has been destroyed then do not worry about completing this DO NOT FEEL LIKE YOU MUST GO OUT AND BUY SILLY PUTTY)
1. Place in fridge for 10 minutes. Drop from 30 cm and record how high it bounces.
2. Place 6 inches from a light bulb for 5 minutes (remember keep away from fabric and carpet) Recheck bounce height.
Wednesday/Thursday: Research the source, composition and properties of asbestos.
1. What properties made it suitable for construction in the past?
2. How did these same properties cause asbestos to become a health hazard.
3. What is being done to eliminate the hazard?
4. What substances do they use nowadays to replace asbestos?
Class Re-Cap:
We began class by making silly putty. Another colloidal substance. We let it sit while we took the quiz, went over homework, and defined the last few groups of the periodic table. We also focused on the differences between metals and non-metals. We then experimented with our silly putty (which did not turn out very good-yet it still bounced but lacked the stretchability which is characteristic of silly putty). We pack alot into 1 hour and 15 minutes. My hope is that each student is seeing the magnificence of God's intricate creation.
The experiment on page 27 didn't go right for me. In fact, the results were flip-flopped than what the paper said was suppose to happen. I did it twice, both with the same results. Any idea what I'm doing wrong? I followed the instructions to a letter, and it still came out wrong.

Ha. That was fun. We are laughing right now cause we just spilled bubbles all over the table! The expiriment (page 27) didn't really work though. Both cups turned out the same, tons of bubbles!!! We are going to try it again.

For me, the "hard" cup had way bigger bubbles, and they were a different shape, but not much else. It WAS fun, though!

When I did it, it was pretty even between the two. (With the bubbles) I don't think the experiment was very clear on what you should see.
ReplyDeleteHey Guys-You would most likely see the results more dramatically with distilled water. I will explain in class but Harrison I would try this if you have any on hand. I will talk more about the concept in class. See you in a couple of days:)
