Understanding Speed and Motion Through Practical Activities and Questions

DESCRIPTION

This journal entry explores concepts of speed and motion, providing engaging activities and thought-provoking questions. Students calculate the speed of an airplane traveling from Minneapolis to New York and analyze a train's journey distance and time. They measure their own walking and running speeds over 10 meters, promoting hands-on learning. Key vocabulary terms include speed, velocity, motion, and acceleration. Activities such as group measurements and graphing personal data allow students to understand motion's dynamics in everyday scenarios.

Presentation Transcript

  1. Speed and Motion

  2. 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?

  3. 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

  4. 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.

  5. Measuring Speed • Make a table in your science notebook, P. 28. • You will be working in groups of 4.

  6. 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.

  7. 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.

  8. 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

  9. 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)
