1. Based on data collected, graph and calculate average speed using distance and time. WARM-UP Student Objective Tell me about the motion of the object for each part of the graph. *See next slide

2. Speed Graph Time A Steady, fast, away B Speeding up, away C Stead, medium, away D Stopped E Steady, medium, closer

3. - Describing and Measuring Motion Calculating Speed If you know the distance an object travels in a certain amount of time, you can calculate the speed of the object. Speed = distance ÷ time

4. Calculate the speed of each animal after one minute (60 sec.) has elapsed. RabbitSpeed = D/T Speed = 1000m / 60sec Speed is _______ TortoiseSpeed = D/T Speed = ______m / 60sec Speed is _______ CheetahSpeed = D/T Speed = ______m / ____sec Speed is _______ 4 200060 16.67 m/s 0.07 m/s 33.33 m/s

5. Calculate each snowmobile’s speed and predict the winner. Then race them to see if you were right! http://sunshine.chpc.utah.edu/Labs/ForceAndMotion/act1/lab.ht m

6. How Fast Can You Get Your Shuttle to the Spaceship? You will now complete a online graphing activity to see how fast you can race through space to the mother ship!! Can you make it in time? Spend 5 minutes trying to make the trip to the mother ship as fast as you can Read the directions carefully and away you go! Answer the questions on your worksheet. Distance Time Graph Activity 6

7. Answer the following question on your notebook paper. (Distance in miles, time in hours) 1.How many miles away was the shuttle from the spaceship at the beginning of the trip? 2.How far away was your shuttle from the spaceship 10 hours into the trip? 3.How far away was your shuttle from the spaceship 20 hours into the trip? 4.How far away was your shuttle from the spaceship 25 hours into the trip? 5.Where in your trip were you traveling the fastest? How do you know?? 6.Where in the trip were you traveling the slowest? How do you know?? How Fast Can You Get Your Shuttle to the Spaceship?

8. Extension How did the various objects in space affect the speed of your shuttle? Do you think you were traveling at a constant speed in your shuttle? Why or why not? Be prepared to share your responses with the class. 8

9. Conclusion: Which animal is the has the fastest speed? Animal A. 10 miles in 2 hours B. 50 miles in 25 hours C. 15 miles in 5 hours
