Shoulder Partner Turn and talk to your partner

Shoulder Partner…. Turn and talk to your partner. The partner closest to the door ask, “How do you win a race? ”. The partner closest to the window should answer! Then switch.

In a race… The same amount of distance around a track is covered. How do you win? You need to cover the same amount of distance as everyone else, in the shortest amount of time! The goal by the end of the day, can you identify the person or object who covers the most distance in the shortest amount of time!

AIM: Scientists will be able to calculate the velocity of cars, animals, and all sorts of moving things and read a graph to determine the fastest participant!

Who’s faster MAN or BEAST? http: //www. youtube. com/watch? v=gz. F 2_Ao. P BY 4

Calculating velocity lets us compare how things move, plan trips, and predict how things will travel. Let’s learn how to calculate speed.

What is the fastest animal in the world? Whiteboard practice

5 th place The Quarter horse, although very big, comes in 5 th place. In 3 seconds, the quarter horse ran distance of 57 meters north. What is its velocity? 19 m/s NORTH

4 th place: The Lion ran 105 meters west in 5 seconds. What is the velocity of a lion? 21 m/s west

3 rd place: The wildebeest comes in 3 rd place. He ran distance of 660 meters east in 30 seconds. What is the velocity of the wildebeest? 22 m/s east

2 nd place: An antelope is an extremely fast animal… It takes an antelope 10 seconds to run 260 meters. 26 m/s Why is this not a velocity?

1 st place: A cheetah ran 145 meters south in 5 seconds. What was its velocity? 29 m/s South

Distance vs. Time Graphs

Graphing Motion Shows motion of an object Distance on y-axis Time on x-axis Slope = steepness of a line Steeper slope = greater speed

Calculating Speed Slope = rise/run

1) What is the speed of the vehicle?

2) How far has the vehicle travelled after 1 second?

1) Which car is travelling the slowest?

2) How far has car #2 travelled in 2 hours?

3) What is the speed of car #2?

Guided Practice Graph #1 1) What is the speed represented in the graph?

Guided Practice Graph #2 1) Which speed is the fastest?

Guided Practice Graph #2 2) How fast is speed #1?

Guided Practice Graph #2 3) How fast is speed #3?

Guided Practice Graph #3 1) Which car is moving the fastest?

Guided Practice Graph #3 2) Which car is moving the slowest?

Guided Practice Graph #4 1) Which car is moving the fastest?

Guided Practice Graph #4 2) Which car is moving the slowest?
