1. Are we there yet? I'm so fast that last night I turned off the light switch in my hotel room and was in bed before the room was dark. Muhammad Ali

2. Learning Goals Students will be able to: 1)Algebraically manipulate the equation To solve for an unknown variable. © 2014, Simplify Science Select LLC

3. What we already know… The slope of a distance v. time graph gives you the speed. Speed can be calculated using the formula: © 2014, Simplify Science Select LLC

4. What we learned in the lab… Distance can be predicted given the speed and time Your brain does these calculations when catching, avoiding, crashed, and navigating traffic © 2014, Simplify Science Select LLC

5. Using a D v. T Graph You can obtain distance and time information as well as speed from the graph.

6. Finding Distance Find the time and draw a line straight up to the slope then across to distance

7. Finding Time Find the distance and draw a line straight across to the slope then down to time

8. Developing A-1 What would be an appropriate title for this graph?

9. Proficient A-2 What time will the object reach 80 m?

10. Mastery A-3 How far does the object travel (STANDARD UNITS) in half an hour?

11. Algebra Sometimes you are interested in distance or time not speed. Algebra makes your life easier No need to memorize multiple equations.

12. Rearranging the Equation Start with your equation s = d / t Multiply both sides by ‘t’st = d (distance) Divide both sides by st = d/s (time)

13. Fundamental B-1 Why does algebra make your life EASIER in this class?

14. Developing B-2 Write the 3 different versions of the speed equation and describe when you would use each.

15. Proficient B-3 How far will a baseball traveling 35 m/s travel in 4.8 seconds?

16. Mastery B-4 How long (in standard units) will it take a car traveling 60 miles per hour to travel 15,000 m?
