5.Activity 2 (Part 1)

Review Activity 1 Steps to Handle Unknown Substances

• Assume they are hazardous• Do not get close to the unknown

substances• Notify adult, Police/Fire Department• Call “Hazmat” Team. It …

• Observes and tests from distance• Wears protective clothing• Protects eyes• Avoids inhaling fumes/gases• Avoids contact with the skin• Takes samples to test and identify substances• Disposes of unknown substances at an

appropriate site

Think about Activity 1…

How useful is to follow these steps when you are handling chemicals at home, out in another building, or in labs? Explain.

Activity 2: Types of HazardsObjective

Students will be able to:• Identify the hazards associated with the

use of chemicals.

Purpose

Students will apply their new knowledge to:

• Handle hazardous substances safely in different situations and environments.

Homework

1. Add the science words (Pre-Lab) with your definitions to the Glossary.

2. Work on Science Fair project

Activity 2: Types of Hazards

• Set up Activity 2 (p. A6)

• PRE-LAB: corrosive, toxic, flammable, biohazard, oxidizer, radioactive

• Paste Data Table to Journal (provided by teacher)

• Read Introduction p. A6
