Journal question

Journal Question

  • 03 Oct 2012, P. 26

  • How fast is an airplane traveling if it takes 2.5 hours to go from Minneapolis to New York (1200 miles).

  • Agenda

  • Measuring and recording speed data.

    • How fast do you walk/run 10 meters?


Journal question1

Journal Question

  • 04 Oct 2012, P. 27

  • A train is moving at 50 miles per hour.

    • How many miles did it travel in 2 hours?

    • The train needs to travels 500 miles. How long will it take to travel this distance?

    • Remember: Speed = Distance divided by time


Journal question2

Journal Question

  • 05 Oct 2012, P. 27

  • Wendy is riding her bicycle downhill at 15 miles per hour. What is her speed? What is her velocity?

  • How fast is Wendy going if she traveled 3 miles in a half of an hour?

  • Show your work.


Measuring speed

Measuring Speed

  • Make a table in your science notebook, P. 28.

  • You will be working in groups of 4.


Measuring speed1

Measuring Speed

  • Measure out 10 meters.

    • Mark start and end with a small piece of colored tape.

  • Start the timer.

    • Walk heel-to-toe for the entire distance.

    • Stop timer at the end.

  • Record your data.


Agenda

Agenda

  • Complete 10 meter walk and run (hallway right outside of our classroom).

  • Complete the directed reading assignment.

  • Begin graphing your walk and run data.


Journal question3

Journal Question

  • 08 Oct 2012, P. 29-30

  • Sharon wants to meet her friends for lunch on the far side of a lake at noon (12:00). She must travel 6 miles across the lake. If she leaves at 10:00 AM, how fast must she travel to make it to lunch on time?

    • Speed = Distance/Time


Vocabulary

Vocabulary

  • Speed – measurement of distance traveled in a period of time (mi/hr, m/s)

  • Velocity – speed with direction

  • Motion – a change in an object’s position over time relative to a reference point

  • Reference point – a non-moving or stationary object

  • Acceleration - measurement of how fast velocity changes (mi/hr2, m/s2)
