Work-Energy Theorem Applied to a Cart Pulled Down a Track
In this activity, students will analyze the relationship between the maximum speed of a cart pulled by a falling mass and the work done by gravity. Students will measure the speed of the cart, calculate the work in each trial, make a graph of speed vs. work, and determine an equation which will ...https://education.ti.com/en/activity/detail/workenergy-theorem-applied-to-a-cart-pulled-down-a-track
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
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
DC Circuit Analysis
Shows three examples of the use of nodal analysis to solve linear circuits. The first two examples use the solve() command to solve a set of linear equations for circuit. The third example shows how to write the equations in matrix form and use simult() to solve them.https://education.ti.com/en/activity/detail/dc-circuit-analysis
Fourier Series
Shows how to compute and graph the complex Fourier Series coefficients for a square wave.https://education.ti.com/en/activity/detail/fourier-series
Vectors
Describes how to use the TI-89 for coordinate system transformations, vector algebra, and vector component transformations. The functions rec2cyl(), cyl2rec(), rec2sph(), and sph2rec() are created in this chapter for vector component transformations and are used in Chapters 10 and 11.https://education.ti.com/en/activity/detail/vectors
Sampling Distributions
Students studies the distribution of sample proportions with a simulation. They find small sample size leads to skewed distribution and as the sample size increases, the distribution becomes more normal.https://education.ti.com/en/activity/detail/sampling-distributions
