LAB REPORT• Homework for this week is to complete a
typed lab report for the lab done on Monday.
• This report is due this Friday March 9th and you will lose 10 points for each day late. See the rubric for how your report will be graded.
• Emailed projects/Flash Drives will NOT be accepted. Use the computer lab to print out your work.

PROCEDURE• 1. Using piece of tape mark off the following locations on
the floor or a tape: 0 meters 1 meter 2 meters 3 meters.
• 2. Place the car on the floor about 0.5 meters in front of the tape that is marked at 0 meters. Start the car and allow it to move toward the 0 meter mark.
• 3. When the front of the car reaches the 0 meter mark start your stopwatch. Then stop the stopwatch when the front of the car reaches the 1 meter mark. Record the time in the table below.
• 4. Repeat this procedure for 2 more trials.
![Page 6: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/6.jpg)
• 5. Calculate the average time and record in the table.
• 6. Calculate the average speed using the formula given in the background and record in the table.
• 7. Repeat the steps above but this time allow the car to move from the 0 meter mark to the 2 meter mark. Do this for three trials. Then do the same thing and allow the car to move from the 0 meter mark to the 3 meter mark and do this for three trials.

The Atticus Scale
When Harper Lee wrote her first and only novel, To Kill a Mockingbird in 1960, she had no idea that she was creating one of the most influential works of fiction in modern history and, in the character of Atticus Finch, one of the most moral literary heroes of all time.
The following is an adaptation of Lawrence Kohlberg's Six Levels of Moral Development based on the character of Atticus Finch. In everything that we do, whether it be handing our homework in on time, waiting to put our gum in a trash can instead of under a desk, helping a total stranger on the street, or taking a stand against bullying, we must ask ourselves what our reasons are for behaving the way we do. Only through personal reflection and analysis of these behaviors can we eventually progress to the height of moral development.

The Atticus ScaleLevel I: I Don't Want to Get in Trouble
Level II: I Want a Reward
Level III: I Want to Please Somebody
Level IV: I Follow the Rules
Level V: I am Considerate of Other People
Level VI: I Have a Personal Code of Behaviour and I Follow it (the Atticus Finch Level)

Topic: Distance-Time Graphs
![Page 22: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/22.jpg)
SPEEDa SCALAR quantity which refers to “how fast an object is moving”
VELOCITYa VECTOR which refers to “the rate at which an object changes its position”
![Page 23: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/23.jpg)
Distance-Time GRAPH
A graph that shows how position
depends on time
![Page 24: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/24.jpg)
The slope of a distance-time graph represents the velocity.
![Page 25: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/25.jpg)
Distance vs. Time Graphs
• Slope positive = constant speed moving
away from starting point
![Page 26: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/26.jpg)
Constant Speed:
• Speed that does not change!• Slope of graph will be the same
throughout.
![Page 27: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/27.jpg)
Distance vs. Time Graphs
• Slope 0 = not moving
![Page 28: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/28.jpg)
Distance vs. Time Graphs
• Slope negative = constant velocity
toward starting point
![Page 29: Do now](https://reader035.vdocuments.net/reader035/viewer/2022070421/56815ff8550346895dcef90d/html5/thumbnails/29.jpg)
Determining Slope of a Graph
• The slope of the graph is the change in the y-axis OVER/DIVIDED BY the change in the x-axis between two points on a graph. (Rise over Run!)
• D = Change• Slope = Dy OR Slope = Dx 12

• The starting point of movement will always be at y=0! • Between 0 and 6 seconds = ______________ velocity away from
starting point.• Between 6 and 11 s = ______________ velocity toward starting
point.• Between 11 and 12 s =______________ velocity away from

The starting point of movement will always be at y=0! - Between 0 and 6 seconds = Positive velocity away from
starting point.- Between 6 and 11 s = Negative velocity toward starting
point.- Between 11 and 12 s = Negative velocity away from
starting point.- Between 12 and 24 s = No velocity (stays at same position)- Between 24 and 28 s = negative velocity toward start- Between 28 and 33 s = pos. velocity away from start.

Matching Cards
• Take turns at matching pairs of cards. You may want to take a graph andfind a story that matches it. Alternatively, you may prefer to take a story andfind a graph that matches it.• Each time you do this, explain your thinking clearly and carefully. If youthink there is no suitable card that matches, write one of your own.• Place your cards side by side on your large sheet of paper, not on top ofone another, so that everyone can see them.• Write your reasons for the match on the cards or the poster just as we didwith the example in class. Give explanations for each line segment.• Make sure you leave plenty of space around the cards, as eventually youwill be adding another card to each matched pair.
