The American tradition might date to President William Howard Taft in 1910, but it could have started in 1869. The seventh-inning stretch, when fans rise from their seats for a brief break after the top of that inning is complete, is as...

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.

Students determine the relationship between the stretch of a spring and the number of weights in a cup suspended from the spring. They find the Y-value of a function if the X-value is provided. They use technology to plot a set of...
