Students are introduced to the calculator as a graphing tool and distinguish between average speed and instantaneous speed.https://education.ti.com/en/activity/detail/graphing-motion-instantaneous-and-average-speed-follow-up-activity-scalar-and-vector-quantities
Who Started It All? The Spread Of Disease
Students predict the spread of disease to be exponential. They then do a hands on "sharing of bodily fluids" and see the actual data and compare these results to the projected model. You actually see the number of infected after each sharing to see the shift of the model easier. Written to be c...https://education.ti.com/en/activity/detail/who-started-it-all--the-spread-of-disease
Centripetal Acceleration
To observe the centripetal acceleration of an object in uniform circular motion. Relate the changes in velocity and radius to the centripetal acceleration.https://education.ti.com/en/activity/detail/centripetal-acceleration
Circular Motion
In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you will measure the tension and the length of the string to ...https://education.ti.com/en/activity/detail/circular-motion_1
