Presentation transcript:

Observe, describe, and compare the motion of objects using speed. Based on data collected, graph and calculate average speed using distance and time. WARM-UP Student Objective Go to or to review speed vocab. (Room: mlkelly)

Kahoot! Go to internet, then kahoo.it Enter PIN Exit slip: Matching Vocabulary

In Each Group: 1.Walker: This person chooses what pace to walk at and stays in place for at least one interval 2. Timer: This person tells the walker when to start and stop, at 3 second intervals. - You need to keep pace with the walker so they can hear you. -Be sure data is recorded and human marker is standing next to the walker before saying start again. 1. Human Marker: Stand next to your walker at start & stay there until your group’s data has been recorded. 2. Data Recorder: Records data in the 1 st distance column. 3. Measurer: Measures from the human marker to the walker in meters (ex: 5.25 m) and tells this number to the data recorder.
