HW#22a -- Thursday, March 8th

Your HW assignment for today is to write a four-paragraph essay about rubber and plastics. The first two paragraphs should have 3-5 sentences each, and should explain what rubber is, what natural sources we get rubber from, and the things we use rubber for. The last two paragraphs should explain what plastics are, how we make them, and the things we use plastics for.

One of the best sources for this assignment is wikipedia, which is a great starting place. It will certainly give you a good definition for "rubber" and "plastics." It should also show you how we get these substances, as well as how they are used to make things around the world!

Sorry, I was a little lit later uploading this than I had hoped (garden club meeting went later than I expected!):





////////////////////////////////////////////////

This assignment will be good practice for the test next week, as it has all three skills in it -- "identify reaction type," "find molar mass of chemical species involved in a reaction," and "use molar ratios to solve stoichiometry problems."

No HW for Wednesday -- instead, finish in-class assignment:

There is no new online assignment today. Instead, make sure that you finish the eight problems From class. Once they're complete, put them in your binder with your Feb. 29th and Mar. 1st notes. If you need to see them again (to get them down), here they are:

No new online work today... just finish in-class practice

These were the problems that we looked at in class; actually, I believe that 1st period saw some slightly different problems. If you were in 1st period, just make sure you've worked out at least FOUR problems total as practice. Have the work on your notes sheet, and store it in your binder so you can show me during a binder check.
