During the last minute, practice making bubbles. • Students will blow a bubble and measure, then record the results in a data table. Pair up to measure the diameter of your bubble (in cm). Use the beaker tongs and a ruler.

  6. Create a Graph: • Using the graph paper provided, create a graph. Make sure the graph includes the following features and rules. • Title • X – Axis Label • Y – Axis Label • Intervals (make sure they are equal) • Key or legend
