Phosphate Analysis
One method of measuring the phosphate concentration is by using a Colorimeter. This instrument measures the amount of light transmitted through a sample at a given wavelength. The amount of light absorbed is mathematically related to the concentration of the solution.https://education.ti.com/en/activity/detail/phosphate-analysis
Solving Equilibrium Problems
In this activity, the students will use the Calculator application to determine the unknown species (x) using known initial concentrations, the change in concentration, and a given value for the equilibrium constant (K). The student will use the following functions: the Calculator Application the...https://education.ti.com/en/activity/detail/solving-equilibrium-problems

Designing Hot and Cold Packs
Purpose: To calculate the molar enthalpy of dissolving for three ionic solids, and to use this information to design a cold pack. In this experiment you will measure the heat changes which occur from various salts dissolving in water, and then you will use this information to design a hot pack an...https://education.ti.com/en/activity/detail/designing-hot-and-cold-packs
How Long Ago Did You Have A Mole?
A great activity for mole day (10 / 23) or with radioactive decay! In this activity, students will predict when a 'mole of a substance' was presence. Based upon radioactive decay rate of a substance, the initial amount found, and the mole concept students will create a graph and interpolate wit...https://education.ti.com/en/activity/detail/how-long-ago-did-you-have-a-mole
Absorption and Radiation
Different surfaces absorb and radiate radiation at different rates. In this activity you will analyze the absorption and radiation rates of two surfaces by monitoring the temperature changes of each of them.https://education.ti.com/en/activity/detail/absorption-and-radiation
Equipotentials and Electric Fields
In this activity, students explore the concept of equipotentials around point charges. Students use the simulation to plot equipotentials and observe the patterns near a single positive charge, near two positive charges, and near a positive and a negative charge. Students also explore the relat...https://education.ti.com/en/activity/detail/equipotentials-and-electric-fields
Cells Never Lie
A forensics activity which deals with the idea of alcohol poisoning. Based on a Vernier Biology Lab on cell distruction in alcohol and Chemistry's Beer's Law.https://education.ti.com/en/activity/detail/cells-never-lie
Who Started it All?
Students look at the spread of disease and predict the model for that spread. Data is taken at the end of each "sharing" and the exponential model predicted is found to be faulty. The logistic model is then explore. Since we have the list of contacts and the data per contact we can trace it ba...https://education.ti.com/en/activity/detail/who-started-it-all
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
Calculator Pattern Pizzles
This lesson will allow young children to explore number patterns and relationships while introducing the calculator at the same time.https://education.ti.com/en/activity/detail/calculator-pattern-pizzles
Meet my friend the calculator
This activity/lesson introduces the students to calculators and how to use them to find numbers 1 - 20.https://education.ti.com/en/activity/detail/meet-my-friend-the-calculator
Graphs and Fractions
Have students draw squares on graph paper and half some of the squares on the outside. Number all the squares and continue numbering with the halfs. Students are then instructed to create their own ratios such as: 4 halves to eight wholes of odd numbers etc. Encourage student's to be creative by ...https://education.ti.com/en/activity/detail/graphs-and-fractions
Surface Area of Cylinder Song
Here's a silly song that I use with my classes to help them remember how to find the surface area of cylinders. My students actually suggested that I submit this!https://education.ti.com/en/activity/detail/surface-area-of-cylinder-song
Conics in Geometry
This lesson has students construct 3 conic sections through geometric definitions. Using the CABRI™ Geometry II application for the TI-89, students construct a parabola, an ellipse, and a hyperbola. (Topics - geometric shapes.https://education.ti.com/en/activity/detail/conics-in-geometry
Going in Circles - Inscribed Angles
This lesson has students discover properties of inscribed angles in a circle. Students use the Geometer's Sketchpad application for the TI-89 to construct a circle and an inscribed angle. (Topic - circles)https://education.ti.com/en/activity/detail/going-in-circles--inscribed-angles
Creating piece wise functions using CBR system
In this lesson, students will use the CBR ranger to model walking distance over time. They will walk away from the sensor, back towards the sensor and finally away from the sensor over an interval of 10 seconds. The result should be 3 lines. They will then use algebra skills to get the three eq...https://education.ti.com/en/activity/detail/creating-piece-wise-functions-using-cbr-system
