1. LAB SAFETY

Welcome to Chemistry. The first order of business is to familiarize yourself with the lab room you will be working in. This safety activity will review rules you are familiar with and introduce you to new ones rules which are unique to Chemistry. At the culmination of this lab, you and your parent/guardian will read and sign a safety contact. You will be held responsible for performing and behaving in a safe manor throughout the year. You will be required to pass the safety quiz before performing any other labs.

PRE-LAB QUESTIONS

1. Set up your lab notebook as specified by your teacher. 2. What is the purpose of this lab activity?

OBJECTIVE

1. Familiarize yourself with safety equipment in the classroom. 2. Review safety rules. 3. Conduct safety orientation activities 4. Formulate safety rules

MATERIAL

7 stations with posted questions

PROCEDURES

1. Start at the station where you are seated. Stations can be done in any order. 2. Stay with your lab table group. Read the question on the card. 3. Perform the activity as stated and record information on the data table. 4. When group is ready, switch to the next station.

STATION QUESTIONS/ACTIVITIES

1. What is the effect of acid on clothing? GOGGLES AND GLOVES ARE REQUIRED 2. What is the effect on acid on skin or eyes? GOGGLES AND GLOVES ARE REQUIRED 3. How do you safely light a Bunsen burner? GOGGLES REQUIRED 4. Can all these materials be used to run an experiment? 5. Why is this not a safety station? 6. What is wrong with this lab station? *7. Identify each piece of equipment. Give brief description of their use. Record.

CONCLUSION

1. Complete data table. 2. State at least one safety rule associated with each station (6 rules).

2. Classification of Matter

Introduction: There are many ways to classify or group matter. Chemists have agreed upon a general system of classification. After you become familiar with the terms you will examine different samples and classify them.

DO NOT OPEN VIALS

PRELAB

1. What is the purpose of this activity 2. Define the vocabulary words on the chart provided.

Procedures:

1. Working in lab groups as assigned by your teacher. 2. Exam the sample in the vials. Do not open the bottles. 3. In the chart provided, describe some physical characteristics (color, shape, phase...), then indicate the

state of matter as: S = solid, L = liquid, or G = gas. 4. Sort the substances into similar groups. (Example: all the elements .....). Conclusion: 1. Fill in the conclusion chart, by listing the substance in one of five groups.
