It will cover all we’ve done this year, see your course outline for more details.
In addition to the tested units, you will also have DNA, RNA, and Protein Synthesis as well asa small amount of Recombinant DNA technology (use s-moodle if you can’t locate the items in your textbook)
Pork Bung and Stomach dissection; drawings due Feb 1st
Vitamin Presentations DUE/ready to present: Feb 1st and 3rd (a sample powerpoint presentation is now available at s-moodle, the password was given earlier, ask a friend or come see me if you’ve forgotten).
Students are asking how best to prepare for this midyear exam; although already discussed in class, s-moodle is the best place to go for powerpoints on all topics and the SUPERNOTES, pdf format, at the top of the page.
Support this review with something “active”, reading is not enough (flash cards, webs, flow charts, etc).
Grade 8’s ~ you can bring a cheat sheet into the Midyear Exam (See Mr Sommerfeld for more details; hint, use the Review Questions that came with the Course Outline for Science 8 in September).
The Midyear covers chapter 1, 2, 3, and 4.
Bring two pencils, your go card for identification, and an eraser. Calculators are also allowed.
Use the following diagram to guide your Activity 5.3 Ray Diagram:
Notice the incident ray, i, forms an angle to the Normal and is the same going in and coming out of the block. The little r stands for refraction.
Place the cleaned chitterlings into a large pot; cover with water and vinegar. Add bay leaves, onions, potatoes, green or red pepper, garlic, salt, and pepper. Bring to a boil; turn heat to low and simmer approximately 2 1/2 to 3 hours or until chitterlings are tender.

Chapter 6 is all about making predictions: what product will form? We can CLASSIFY reactions into six reaction types in chapter 6. Imagine that 😉
____________________________________________
Let’s look at what happens in the Find Out Activity, through video (so we don’t hurt the environment and each other):
Copper (ii) Chloride with an Iron nail (@ 2 mins)
with Magnesium
with Zinc
This is just one of six reactions we’ll learn about, called a Single Replacement Reaction (or SR for short), as explained by “this” guy:
And there are five more in this chapter!
Synthesis Reactions (2 reactants form a product: here it’s chlorine with sodium to make sodium chloride (table salt)!
Decomposition Reactions: Hydrogen Peroxide decomposes into water and oxygen (using Potassium Iodide as a catalyst, famously called “elephant toothpaste”)…
Double Replacement reactions: an example here of Lead Nitrate with Potassium Iodide –> predict the products!!
Neutralization reactions: ( we did this in Chapter 5 )
Quick demo out of Berkley
Everything you wanted to know about neutralization reactions and then some!!
and finally, Combustion reactions (we can do this one just before XMAS, anyone got some DAWN??!!) –> three more videos, just for fun…
