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?id=F78E9383D2814AEC93DA71D28E9B642B
Exponential Growth Experiment
Students will work in pairs and will conduct a growth experiment. They will record their answers for 7 to 10 trials. They will make a scatterplot of their data and share their graphs with the class.https//education.ti.com/en/activity/detail?id=CF9BCB8D518B4F728F56882C291DB25D
Exploring Exponential Decay
Students will work in pairs and conduct an experiment with M&M's where they start with a cupful and continue to decrease the n umber of M&M's in their cup.https//education.ti.com/en/activity/detail?id=6303CEFBBBDA40D0BF22B1213D480766
Linear Equations and Their Graphs: Rate of Change
The mathematics goal of this activity is to deepen students' understanding of slope by solving two meaningful and relevant problems involving rate of change. In this activity, students utilize their understanding of patterns and algebraic rules to learn about slopes and y-intercepts. Further, t...https//education.ti.com/en/activity/detail?id=DC7EDCF64F564804B7730E61085B6BEA
Properties of Parallel Lines Cut by a Transversal
