Water Quality Testing
This water quality project has been designed around a monthly sampling routine for the extent of the project scope. One of the sampling days involved three different classes, each class sampling a different station. This project measured several biotic / abiotic factors to determine the interre...https://education.ti.com/en/activity/detail/water-quality-testing
Fundamental Theorem of Algebra
Students generate random polynomials and observe the distribution of the zeros on the complex plane. From the distributions students are able to draw conclusions about the zeros, and therefore roots, of a polynomial in order to gain a better visual understanding of the Fundamental Theorem of Alge...https://education.ti.com/en/activity/detail/fundamental-theorem-of-algebra
Vernier - Exploring Magnetism
In this lesson, students will investigate the relationship between the orientation of the sensor and the strength of the magnetic field.https://education.ti.com/en/activity/detail/vernier--exploring-magnetism
Tool - Unit Conversion
In this lesson, students are introducted to the basics of how to effectively use this tool. This tool can be used alone, or you can copy/paste it into another TNS document.https://education.ti.com/en/activity/detail/tool--unit-conversion
Pendulum Swing – Part 1
Students use a motion detector (CBR) and pendulum (fishing float) to collect data for the motion of a pendulum. The quality of the data never ceases to amaze students and teachers. Students align practical knowledge, logic and familiarity with the various parameters to transform a basic trigono...https://education.ti.com/en/activity/detail/pendulum-swing--part-1
Like Moths Around a Flame
In this lesson, students examine data about moths and draw conclusions of how the environment impacts their populations.https://education.ti.com/en/activity/detail/like-moths-around-a-flame
Terminal Velocity
In this lesson, students will define terminal velocity and analyze the relationship between mass and terminal velocity.https://education.ti.com/en/activity/detail/terminal-velocity
The River of Life
In this lesson, students will calculate the volume of blood in their own bodies based on a linear regression.https://education.ti.com/en/activity/detail/the-river-of-life
Fill the Vase
Students interpret graphs of empirical data with respect to rate of change of the height of water in vases of different shapes that are being filled at a constant rate. Students are provided with a range of graphs and vases. For each graph they must reshape the vase in order to match the volume –...https://education.ti.com/en/activity/detail/fill-the-vase
Sweating Alcohol
In this lesson, students will measure and graph the rate at which room-temperature water and alcohol cool as they evaporate. Then, they will draw a conclusion about the rates at which polar and nonpolar liquids evaporate.https://education.ti.com/en/activity/detail/sweating-alcohol
Vectors Introduction
An introduction to vectors visually, conceptually and numerically. Students manipulate vectors to show addition (head to tail) and the parallelogram rule. Students use a column matrix to represent a vector and explore scalar multiples and the magnitude of a vector.https://education.ti.com/en/activity/detail/vectors-introduction
Cellular Respiration
In this activity, students will use a carbon dioxide gas sensor to measure the rate at which non-germinating and germinating peas undergo cellular respiration. Students also investigate the influence of temperature on the rate of cellular respiration.https://education.ti.com/en/activity/detail/cellular-respiration
Intermolecular Forces
In this lesson, students will first observe the changing charge cloud that surrounds a single polar molecule (HCl) and a single non-polar molecule (Cl2).https://education.ti.com/en/activity/detail/intermolecular-forces
