Students build on their existing air quality knowledge and a description of a data set to each develop a hypothesis around how and why air pollutants vary on a daily and seasonal basis. Then they are guided by a worksheet through an Excel-based analysis of the data. This includes entering formulas to calculate statistics and creating plots of the data. As students complete each phase of the analysis, reflection questions guide their understanding of what new information the analysis reveals. At activity end, students evaluate their original hypotheses and “put all of the pieces together.” The activity includes one carbon dioxide worksheet/data set and one ozone worksheet/data set; providing students and/or instructors with a content option. The activity also serves as a good standalone introduction to using Excel.
Piecewise linear functions are presented with examples and definitions. See how piecewise functions are applied to real-world situations through an example with income taxes.
A solution is presented to a student-submitted problem. The problem involves graphing and finding the solution set to a system of inequalities.
The mathematics resource assesses students on linear relations. The activity has problems with graphing and analyzing linear relations. Some of the topics included are variation, scatter plots and linear relationships. The worksheet has problems, challenge activities, and an extension activity.
In this interactive, students use logic and mathematical skill to place animals at the correct points on a Cartesian graph representing the cardinal directions. Then, they use the Pythagorean theorem to determine the distances between points. The riddles in the interactive, including one requiring an understanding of rate, have randomized values so that students can place points at different locations and calculate different distances. The activity provides a review of concepts related to determining the distances between points on a Cartesian graph using the Pythagorean theorem and a response sheet to help students work with the interactive.
