Looking for a fun graphing radical functions activity? Students collect data that follows a radical curve, fit a radical equation to the data, and analyze its features.

Read my graphing radical functions activity blog post for more information on this activity.

There is also an EDITABLE version of this activity: EDITABLE Radical Functions Graphing Discovery Activity

The purpose of this activity is to introduce or reinforce the shape of a graph of a radical function using the formula for the theoretical period of a pendulum. It also serves to give a real world example of radical functions.

Required materials include string and weights of equal mass (could be borrowed from a science teacher or use something like batteries).
