There IS a way to know what's on the test.Have you noticed that the quizzes have large chunks of material taken directly from the worksheets you just finished?
How to do well on any chemistry, physics, or math test:
1. Hard work: During homework check, carefully mark which questions you got wrong. 2. Hard work: Ask someone* who 'gets it' for help. 3. Hard work: Do and re-do that question until it is easy for you. Try it again the next day and make sure it's still easy to solve. 4. Easy: Go relax and wait for test day. Wednesday, September 24, 2014 You can use this data for tonight's graph. Tonight's homework, on paper to hand in, do all of the steps below (we did much of it in class already). 1) Make a table of ten good points for aluminum volume and mass 2) Make a table of ten good points for iron volume and mass 3) In Pencil, on a single large graph that fills most of a page: a. number your Y-axis so that it spreads out your mass values b. number your X-axis so that it spreads out your volume values c. put a title above your graph that is similar to the question you wrote at the top of your data sheet in lab d. in pencil, with a symbol such as a triangle or star, mark ten data points of mass and volume for Aluminum. Use data from your group and from the class data sheet. e. in pencil, with a different symbol, mark ten data points of mass and volume for Aluminum. Use data from your group and from the class data sheet. 4) Don’t connect the points. We will never connect the points in chemistry. Instead use a clear ruler to draw a best fit line that includes the origin (because zero grams should have zero volume) and has an even amount of data points on either side of it. 5) For each substance: a. Label the lines with the substance names. b. On separate paper or below the graph calculate the slope of each line. c. Write a “For Every…” sentence (see your notes from today). d. Write in math terms “1 =…” expression based on your sentence from 7. You can use this data for the graph. Tuesday, September 23, 2014 Notes here. We collected data to tell whether mass and volume of a substance are related in a consistent way. Homework: None. Monday, September 22, 2014 Lab reports for the mass change lab were due today. We used paper rulers with an imaginary unit (The Peppy) to measure a rectangle. There were two take-home points to the lesson: 1) the last digit in any measurement is the estimated digit. example: in 3.209, the 9 is estimated. 2) always read a ruler or other measuring device by estimating how far between the lines you are. the most estimations that we can reliably eyeball in this manner are 10 imaginary divisions. example: if a ruler has a line at 1.1 and a line at 1.2, you can read it to the hundreths: 1.14 would be possible. example: if a ruler has a line at 3 and the next line at 6, the best you can read it to is 5 but not to 5.2 for example. Homework tonight is the unicycle sheet. Friday, September 19, 2014 The quiz today is worth ten points. You should have memorized all your notes, especially the symbols for the 34 elements (see a list BELOW under the September 12 entry).
