Hi All,
Hope you are enjoying your break. Remember that for Monday, January 5th, you have some homework to do (assigned way back in early December). You all hypothesized about two reactions:
1. Mentos and Diet Coke
and
2. Baking soda and vinegar
You should have the scientific method outlined through the results (data) step from our in-class observations.
For each reaction, you need to write up a good conclusion
AND
do a little research to determine if each was a chemical reaction or not.
In other words, was what happened chemical or simply a physical phenomenon. Explain why you say what you say, and cite at least one source that helped you to figure this out.
Happy New Year!

Getting Up To Date
Hey All,
Wanted to detail where we should be:
For today, 11/25, you should have completed the MythBusters scientific method outlines for the eye patch, rum as a cleaner, and cannonball through the ship myths.
Also for today, 11/25, you should have completed the Rocks reading and all of those questions (see previous blog entry).
For Monday, 12/1, please read the "Nuclear Chemistry" packet, highlight it, and be ready for further discussion.
Have a great Thanksgiving!

Rock Reminder
Hey All,
If you did not complete the rock reading and questions (see below on this blog), please complete it for Monday. Have great weekend!

Directions for MythBusting
PIRATE MYTHBUSTERS DIRECTIONS!!!!
For each myth being tested, please set up a new page IN YOUR SCIENCE NOTEBOOK to detail the steps of the scientific method:
* The Question (the myth):
* Hypothesis:
* Experiment Methodology (how did they do it?):
* Explanation of what happened in the Experiment (what happened when they did it?):
* The Data (the information gathered):
* The Conclusion (Was the myth busted or not? Was it a valid experiment? What future research, questions, or experiments stem from this experiment?):

ROCKS!
Hey All,
Thursday is Mythbusters Day, but Wednesday Rocks........
You have a handout about the rock cycle and types of rocks. Now pay attention. This assignment is about to look like one of Sheila's Math Assignment's......
Please answer the following questions by Monday, November 24th.

Page 910 - Reading Check - What is the law of conservation of matter?
Fig 27-3 - What processes cause the uneven surfaces of these majestic mountains?
Page 911 - Section Assessment #1-4
Page 916 - Fig 27-6 - Did the lava that formed these rocks cool quickly or slowly? EXPLAIN YOUR ANSWER.
Reading Check - What controls the grain size of an igneous rock?
Page 918 - Section Assessment #1-4 and Using Math
Page 919 - Fig 27-9 - What other conditions can cause metamorphic rocks to form?
Page 921 - Fig 27-11 - Explain why slate is used for patio and stepping stones and roofing shingles?
Page 922 - Section Assessment - #1-3
Page 923 - Fig 27-13 - How can these rock layers be used to sequence events in time, provided that the layers are not disturbed?
Page 927 - Reading Check - How do chemical sedimentary rocks form?
Page 928 - Problem Solving Think Critically (at the bottom)
Page 929 - Fig 27-17 - What types of organisms died and were buried to form this coal?

EMAIL SCIENCE GOALS AND QUIZ
Hi All,
Please email me your 3 science goals for the rest of the semester (through the end of January) by tomorrow (Friday, 11/14). These should be science content related - not behaviors. These should include what we have already been studying, as well as chemical composition and characteristics of minerals.
DON'T FORGET: Quiz on the chemical reactions sheet on Monday, 11/17.

Current Work
Hi All,
Great job preparing for your conferences last week. Wanted to remind you of where we stand as we move forward.....
Make sure that your Relevant Elements worksheet is completed (due yesterday).
For Wednesday, November 12th, read the reactions handout (both sides), and make marginal notes and/or highlight the important points. We will discuss this on Wednesday.
As we move forward, we will be looking more closely at chemical reactions. We will also be examining minerals, their chemistry, and their various characteristics.

Homework and Test
Hey All,
Sorry that I missed class yesterday. Hope you enjoyed others' presentations and the wacky British Chem Professors from Nottingham.
Don't forget that we have a test next Wednesday (10/29). Use the test review handout as a your study guide. We will have a thorough review in class next Monday.
Also, any missing homework needs to be handed in by next Thursday (10/30).

Loose Ends
Hey All,
What great inquisitiveness y'all show in class each day - thank you!
Want to make sure that we are on top of the work that is due or coming due soon:
For 10/16, you should have finished your alkali metal/halogen compound write ups (identifying one and describing its uses).
For Monday, 10/20, research and write an understandable paragraph on your chemistry term. If you do not remember yours, please email me.
Have a great weekend!
