Today, we finished practicing SI conversions, took a field trip to the Gulf of Mexico (at least to its water!) and watched a video regarding relative velocity and motion (and some previews of inertia/force/momentum studies to come)
I discussed the content of the exam on Wednesday; it will be short - probably 1/2 to 2/3 of the class period, and you will be using your understandings of density, measurement, and graphing primarily. There will be a small amount of motion - related content on the exam.
You will need to review how to divide by fractions, use units in problem solving, and convert using S.I. prefixes. You will need to understand what density is and how it governs interactions between matter with different densities. You will need to understand the metric system (S.I.) and its advantages. You will need to understand how to measure something accurately (correctly) and precisely (using the smallest units available and not rounding unnecessarily). You will need to understand how to set up a graph as well as how to get information from it (slope of line of best fit - and what does it mean, etc.).
To review:
Re-try homework assigned from the textbook. When we have gone over these answers, did you make corrections or just pitch your paper in the trash?
Review notes we took in class - they should be on this webpage too.
Review how to divide by fractions.
Look back through this webpage to refresh your mind of activities we did to help you learn/master density.
You may use a calculator on this test. You must supply this yourself; I only have a couple to loan and although I try to make sample problems easy to work in your head or on paper, you will have to measure a real object and working with that number may involve calculator necessity.
Weekend homework: Study, have a fun weekend, and finish the optional assignment (due Tuesday).
