Teaching Example/Non-Example
Performance Objective
Students will be able to identify the difference between
Poison Ivy from other types of foliage found outdoors in
woods, gardens and forests.
Audience
The intended audience is Fifth Graders. The lesson will be given
before students begin their Science project where students will
collect various types of plants and bugs. Students will need to have
an understanding and the ability to detect the poisonous ivy plant
from other types of vine like plants to avoid being exposed while in
the outdoors.
Student Measurement
Students will be asked to describe the identifying traits of poison
ivy. Students will also be given a quiz where students are given
pictures of varying types of ivy. Students will be asked to circle
the images of poison ivy.

smooth edges and slightly rounded
cut edges. The leaves are still
grouped in sets of three as the main
indicator of the type of plant.

Poison ivy in the Spring
The groupings of three leaves
together are an indicator that the
plant is poison ivy.
This is an example of poison ivy in
the fall. The leaves take on a mixture
of colors including green, reds and
yellows.
Oils are still very potent even in fall
and winter months.
Poison ivy can be found growing
in trees and along the ground as
a covering. What ever it grows
on, it will eventually kill as it
takes over the area.
