(this dastardly diversion from dog day doldrums devised by Mr. Timothy Bacon, refer your questions to tbacon@rialto.k12.ca.us[->0])

Introduction:
Summer vacation has long been associated with sleeping in, lazy days by the pool, hanging out with friends, learning the vocabulary of harmonic motion, constructing cheesy experiments, and graphing data. Summer 2012 will be no exception. First, I want you to read 3 pages on the internet (Step 1 in “Procedure” below). Then, I want you to print a worksheet from the internet (Step 2). You are to apply what you learned from reading by filling in the 29 boxes on the worksheet with as many correct answers as you can. Research on additional vocabulary may be required (for instance, what is an “independent variable”?) Next, I want you to apply what you learned from reading by constructing a simple experiment where you will carefully record measurements of length and time. You will also take a picture of you with your experiment (Step 19) You will then use your data to construct a graph (Step 21)

Lastly, you will answer questions about the results of your experiment, and put the pages of your completed report in the correct order. Since this is a summer project, you are to bring your completed report with you on the first day of school.

GRADING RUBRIC FOR THIS PROJECT: 100 points
a) At least 5 of the 7 pages turned in on time (first class meeting):7 points b) Report turned in complete (all 7 pages at the same time)7 points c) Data in Table 1 and Table 2 are unique, complete, and correct30 points d) The 12 questions on Page 1 and Page 2 are complete and correct:12 points e) The Graph on Page 3 has a title, labeled axes, and is plotted correctly:8 points f) The picture on Page 4 meets the requirements of Step 197 points g) The answers on the worksheet (Pages 5,6,7) are complete and correct29 points

Procedure:
1)Begin by reading 3 pages on the internet that I have selected for you. In particular, pay attention to the meaning of the following symbols – T, g, and l – and the definitions of the terms “acceleration of gravity”, “amplitude”, “length of a pendulum”, “period”, and “simple pendulum”

For this Wikipedia page, read 1, 6, 6.1, and 6.2 in the “Contents”: http://en.wikipedia.org/wiki/Pendulum 2)The link below takes you to a worksheet. At the top right is the “Printer Friendly Version”, click there and then print it. There are 29 boxes where answers should be recorded; you should be able to figure out most of the answers correctly; incorrect answers are – ½ point, missing answers are -1 point. For me, this worksheet prints as 3 pages; it is Pages 5, 6, and 7 of your project.

3)Gather the 9 items listed in a-i as follows (make every effort to borrow what you don’t have instead of spending money): a) about 10 foot of light string (thread, fishing line, dental floss, etc.) b) thumbtack or push-pin or tape with good adhesive, c) a few ounces of weight that can be tied/attached to the string (examples: car keys, Christmas tree ornament, padlock, anything compact and dense), d) tape measure, e) stopwatch that measures time to the nearest tenth of a second (0.1 sec) or hundredth of a second (0.01 sec); almost all cell phones have this as part of a tool or app, f) a chair or step-stool that is safe for you to stand on to touch a ceiling, g) scissors, h) camera (cell phone OK, but picture will have to forwarded to someone’s email account so it can be printed), i) graph paper (or you can plot your ordered pairs and print your graph at http://nces.ed.gov/nceskids/graphing/classic/ , select “line graph”)...
