Eighth graders are given a linear equation and instructed to find a second linear equation in order to make a system of equations that fits different criteria related to its possible solutions. Aligns with 8.EE.C.8.

In this activity, students collect information about the stops made, time taken, and distance covered by a train on one of Amtrak's routes. They find a mathematical model that can best track the train. Students understand concepts...

In this activity, students explore linear equation models for real-life situations. They learn to find a linear equation when two pairs of related points are on a line.

In this activity, students investigate how a spring stretches when different weights pull on it. They relate the stretch of the spring directly to the weight and vice-versa.

In this task, students are shown a table of U.S. population data between 1982 and 1988 and are asked to explore whether linear functions would be appropriate to model relationships within the data. Aligns with F-LE.B.5 and F-LE.A.1.b.

The operation of bimetallic strips is explained and illustrated. The principle of thermal expansion is related to their operation. A link to applications of bimetallic strips is provided.

Students determine how the temperature of water affects the dissolving time of a sugar cube. They create, interpret and analyze graphs of data, find an equation of the line of best fit, and relate slope to rate of change.

Students compare the heating rates of wet sand and dry sand and study the effect of evaporation on heating rates. They create, interpret and analyze graphs of data. They also relate slope to rate of change.

This activity introduces students to Activity Center. In this activity, students will explore change in the context of cellular telephone charges. Students will create a scatter plot showing that the rate per minute for a "pay as you go"...
