The concepts of weight and gravity were discussed, and the lack of relationship between horizontal speeds and the vertical speeds of falling objects were introduced.
Physical Science: January 2009 Archives
Newton's Laws of motion were reviewed, and Newton's Third Law was explained. Students were asked to classify the forms of friction as a force that opposes all motion.
Instruction was differentiated today, with the students attempting three distinct activities:
- Students went into the hallway to gather data for their "Gravity Racers" laboratory;
- Students were asked to complete a "Distance Time Graphing" activity
- Students were asked to list and define the chapter vocabulary on page 62. There will be a quiz on Friday for the Chapter vocabulary.
Solutions to the homework were presented.
Students read, and I covered the components, procedures, and expectations of the lab we will begin tomorrow.

We completed the following speed/graphing exercise:
Calculating Average Speed.xlsx
I had the students construct a foldable with the three kinds of speed: Average speed, Instantaneous speed, and Constant speed.
We then compared the slope of a line on a distance-time graph as a fast speed (large positive slope), a slow speed (small positive slope), or no speed (no slope - a straight line).
I asked the students to complete the questions (#1-6) on page 46 for a homework grade.

We reviewed the Factor-Label method of unit conversions (also called "Dimensional Analysis") and performed many practice examples including a few from the Speed WS 2.
Yesterday's Speed WS 1 was checked for correctness and the problems were worked on the board.
Students were presented with more speed formula exercises:

The steps for successfully converting from metric to imperial measures and vice versa were covered, as well.

Spring Semester Syllabi were distributed:P S Syllabus - Spring 2009.doc
The concepts of motion and frame of reference were introduced, as well as the speed formula.
Students were asked to complete the nine questions on Speed WS 1 (Speed WS 1.bmp), and put their answers on the Speed WS 1 Answer Sheet (Speed WS 1 Answer Form.xlsx ).
