Measuring Motion SE - Lecture Notes Assignment

Student Exploration: Measuring Motion Vocabulary: distance, speed Prior Knowledge Questions (Do these BEFORE using the Gizmo.) The speed of an animal is how fast it is moving. A speed of 6 m/s (meters per second) means that the animal moves a distance of 6 meters every second. 1. How would you measure the speed of an animal? _________________________________ _________________________________________________________________________ 2. What do you think are the fastest animals? _______________________________________ _________________________________________________________________________ Gizmo Warm-up You have been sent on an African safari by International Geography magazine. Your assignment is to find the fastest land animals in the world. Your only tool is a video camera. The safari is shown in the Measuring Motion Gizmo. 1. On the SAFARI ADVENTURE tab, wait for an animal to pass by. Press the record button ( ). Press stop ( ) when the animal has passed by. A. Which animal did you record? _________________ B. Was the animal walking or running? ____________ 2. Select the PLAYBACK tab. Practice using some of the different buttons on this tab:  Use the Play ( ) button to replay the simulation.  Click Rewind ( ) to go back to the beginning.  Click Advance frame (  Click Tools at upper left, and drag some arrows ( the positions of the animals at different times.  Use the Time slider to go to a specific time. ) to move forward exactly one second at a time. ) onto the recording to mark Get the Gizmo ready: Activity A: Who’s fastest?  Select the SAFARI ADVENTURE tab.  Remove all arrows from the screen.  A calculator is recommended for this activity. Question: Which animal is the fastest? 1. Form hypothesis: Watch the SAFARI ADVENTURE tab for a while. Based on your observations, which animals run the fastest? _____________________________________ 2. Measure: For each animal, measure distance traveled and time using any method you wish. Divide distance by time to calculate speed. Measure running animals only.

Analyze: What is the fastest animal/object? _______________ Slowest? _______________ 2019
