This document provides instructions for students to create a foldable to record data from plant cards, with plant height on the x-axis and petal length on the y-axis, in order to graph and analyze examples of hybridization between different plant and animal species. Examples of hybrids mentioned include mules, beefalo, and broccoflower. Students are asked to identify how many species are represented on the graph and whether any hybrids are present.

9. Foldable
 Hold paper horizontally in front of you
 Fold left edge to the center and crease
 Fold right edge to the center and
crease

11. Collecting Data
 On your paper, create a table to
record plant height, petal length, petal
color, hair on stem.
 Collect data using the plant cards
 Create a coordinate graph with plant
height as the x-axis and petal length
as the y-axis
