1
+ Day 1 – Calculating Speed Mr. Lambert Integrated Science 1A Trimester 2, 2014

2
+ Bell Ringer In your own words, explain the meaning of 100 mi/h and 45 m/s Does running twice as far take twice as much time? Make a pile in your group with your finished Scientific Method Scenarios Homework

3
+ Agenda 1. Bell Ringer 2. Learning Targets 3. Average speed 4. Lab activity 5. Practice problems 6. Exit Slip

4
+ Learning Targets On your Bell Ringer Sheet, write the following: We will use measurements of distance and time to calculate average speed.

5
+ What is speed? What does 60 mph mean? If I travel 50 miles in 1 hour, what is my speed? What about 100 miles in 2 hours?

6
+ What is the relationship between distance, time, and speed?

7

8
+ Units Meters per second (m/s) Miles per hour (mi/h or mph) Kilometers per hour (km/h)

9
+ Lab activity Copy the following table Ramp height (cm) Distance (m)Time (s)Speed (m/s) 51 101 151

10
+ Lab activity Model Measure out 1m after end of ramp 1m

11
+ Lab Activity Wrap-up Compare the ramp height and speed. What pattern do you observe? What is the independent & dependent variable?

12
+ Whiteboards

13
+ Calculating average speed NASCAR fans love race day when they get a chance to cheer on their favorite team! If a driver was able to travel 600 miles in 3 hours, what was his average speed?

14
+ The fastest car on Earth, a British-made Thrust SSC, would win every NASCAR race in America. If it takes 0.5 hours (30 minutes) to travel 380 miles, what is its speed?

15
+ Calculating average speed The fastest train on Earth, the TGV from France, can travel at faster speeds than trains in the United States. During a speed test, the train traveled 800 miles in 2.5 hours. What is its speed?

16
+ Spirit of Australia, a hydroplane boat, made speed records by traveling 239 miles in 0.75 hours (45 minutes). What is its record- breaking speed?

17
+ Calculating distance & time Calculate the distance that you would travel if you drove for: a) 3 hours at 20 mph b) 8 hours at 60 mph c) 2 hours at 80 mph d) 3 hours at 90 mph

18
+ How long does it take to travel: a) 120 miles at 40 mph b) 300 miles at 50 mph c) 240 miles at 60 mph d) 280 miles at 70 mph

19
+ Learning Targets How did we do? I can use measurements of distance and time to calculate average speed.

20
+ Exit Slip A car travels 300 miles in 5 hours. Calculate the average speed of the car. How long does it take for the car to travel 82 miles?
