Activity 2: A Tool for Inquiry
CBL Motion Detector
What can I expect to get out of doing this activity?
|The Calculator-Based Laboratory system and the ultrasonic
motion detector as a sensor provides you with a unique opportunity to observe
the graphing of motion while it is happening.
You will explore the results on a real-time distance-time graph while walking at different speeds and directions.
In this activity you will explore the capacity of the CBL system to visualize:
We assume you got the CBL and Sonic Ranger to work!!
As we stated the CBL can be picky. We are going VERY slowly through this technical setup. If you still have difficulties please call the Texas Instruments CBL HOTLINE (1-800-TICARES).
In this activity we are going to extend only slightly the capacity of the CBL interface. There is plenty of time to work with the CBL. The goal of this second activity is simple:
|60 minutes for continued work with the CBL system.|
|There is no reading assignment for this activity. If you wish you can read more about MOTIONRT in Exploring Physics and Math with the CBL System. WARNING: this material is in Activity 2: (pages 17-19) displacement plots, but the book calls the program DISTANCERT, not MOTIONRT.|
