Forensics Case 4 - Flipping Coins: Density as a characteristic property
In this activity, students identify counterfeit coins based on the characteristic property of density. They model data using a linear equation, interpret the slope and intercept values from a linear model, and identify a characteristic property of a substance.https://education.ti.com/en/activity/detail/forensics-case-4brflipping-coins-density-as-a-characteristic-property
Steppin' Out
Students will use the Data/Graphs Wizard tool to graph data and determine a line that best fits your data and use the Data/Graphs Wizard tool to identify the relationship between stride length and height.https://education.ti.com/en/activity/detail/steppin-out
Forensics Case 14—Hot Air, Cold Body: Using Newton's Law of Cooling to Determine Time of Death
Students create a temperature versus time graph for cooling and become familiar with Newton's Law of Cooling. They use the cooling-rate equation to estimate time of death of the victim.https://education.ti.com/en/activity/detail/forensics-case-14hot-air-cold-body-using-newtons-law-of-cooling-to-determine-time-of-death
Graphing Motion: Instantaneous and Average Speed (Follow up activity: Scalar and Vector Quantities)
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
Blackbody Radiation
This program will produce the blackbody radiation curve for one or two objects when the student inputs the temperature(s) in kelvin. The program will also display on the curve the peak frequency and wavelength when one object is selected.https://education.ti.com/en/activity/detail/blackbody-radiation

Vernier - Heart Rate and Body Position
In this activity, students will use a Heart Rate Monitor to measure their heart rate while sitting, lying down, and standing. They will analyze the data collected to determine the effect of body position on heart rate.https://education.ti.com/en/activity/detail/vernier--heart-rate-and-body-position
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
