Objectives

To help students understand how to select, handle, use, store and dispose of pesticides

Essential Question

Why is it important to read pesticide labels?

Essential Understandings

Pesticides, while useful in controlling unwanted pests, pose a risk to humans, other animals and plants. They need to be used with caution, concern and care.

Background

A pesticide is any substance or mixture intended to prevent, repel, reduce or destroy infestation by plant, animal or microorganic pests. The term applies not only to insecticides, but also to herbicides, fungicides, rodenticides, disinfectants, sanitizers, repellents, biocides, and antifouling agents among others. In the United States, anti-defoliant and plant growth regulators are also classified as pesticides.

Most pesticides, though useful to society for their intended purpose, pose a risk of harm to humans, pets and the natural environment. Therefore, pesticides and their use are regulated in this country by the Environmental Protection Agency (EPA). Extensive testing for negative health and economic impacts must be conducted prior to application for EPA registration, which is required before any pesticide can be sold. This process takes several years and costs companies millions of dollars. Furthermore, by law, the EPA requires strict labeling of all pesticides.

Consumers have a responsibility to read pesticide labels carefully to insure safety and proper use against personal injury, environmental damage and loss, and liability prosecution. Failure to do so may result in unintended results.

Vocabulary

active ingredient-  the major component of the pesticide that produces the desired results

fungicide – a pesticide that controls plant diseases

herbicide – a pesticide that controls weeds and other undesirable plants

inert ingredient – the inactive materials in the pesticide that have no direct effect on the pest but make the pesticide easier to handle and apply

insecticide – a pesticide that controls insects

rodenticide – a pesticide that controls rodents

Challenge:  Become a pesticide professional!

ELA – A3. Reading Informational Texts

A3. Students read various informational texts, within a grade appropriate span of text complexity, making decisions about usefulness based on purpose, noting how the text structures affect the information presented.

Grade 7:

c. Draw conclusions about a text and its purpose, and support them with evidence from the text.

d. Make comparisons about information from several passages or articles from different texts.

Grade 8:

d. Draw conclusions about information from multiple texts and support them with evidence from the texts.

B. Writing

B3. Students write academic essays that state a clear position, supporting the position with relevant evidence. a. Summarize and paraphrase and/or explain information from reading, listening, or viewing.

SCI – B1. Skills and Traits of Scientific Inquiry

B1. Students plan, conduct, analyze data from, and communicate results of investigations, including simple experiments.

c. Use appropriate tools, metric units, and techniques to gather, analyze, and interpret data.

e. Use logic, critical reasoning and evidence to develop descriptions, explanations, predictions, and models.
