• What are the tools that scientists use to gather

information/evidence?

BEHAVIOR EXPECTATIONS

If there are pieces of equipment or a computer at the station, follow directions and treat items with respect

Stay on task – you will receive one warning ONLY

LAB EQUIPMENT - WHAT YOU NEED TO DO

THERE ARE 5 EQUIPMENT STATIONS

LAB TOOLS AND EQUIPMENT STATIONS

Some equipment you will be working with:

STATIONS PAGES/INSTRUCTIONS FOR EACH TABLE – READ

THE INSTRUCTIONS FIRST!!

Thermometer – 2 slides

Graduated cylinder – 2 slides

Triple beam – 3 slides

Meter stick - 1 slide

Digital scale – 1

EQUIPMENT TIPS:

Read the water line in the graduated cylinder at the

meniscus

Once you have used either scale, take the items off or

the scale and put it back to zero.

You can take the thermometers out of the beakers in

order to read the temperature (in Celsius)

Lab Safety sections: The information is at each station,

read both the station pages and your response page in

order to complete the work.

THE THERMOMETERThermometers are very fragile and must be handled with care. Read the following rules for the proper use of a thermometer.

1. Never "shake down" a thermometer to reset it.

2. Never use a thermometer to stir a liquid.

3. Never allow a thermometer to touch the bottom of a container that is being heated.

Read the following directions for using and reading a thermometer.

1. Place the bulb end of the thermometer into the object with an unknown temperature.

2. Wait several minutes for the thermometer to adjust to the temperature of the object.

3. Without removing the thermometer from the object, note the number nearest the top of the column of liquid in the thermometer.

Answer the following questions on the worksheet provided.

1. What are the temperatures shown by these thermometers?

At this station you will notice two beakers that are labeled “A” and “B”. Use your thermometer correctly to complete the following:

2. What is the temperature of Beaker A?

3. What is the temperature of Beaker B?

4. Why must you read the temperature without removing the

thermometer from the liquid?

5.Why should the thermometer never be used to stir a

liquid?

PART II: THE GRADUATED CYLINDER

Read the following directions for using and reading a

graduated cylinder:

1. The cylinder should be on a flat surface.

2. Look at the cylinder from the side at eye level. The top

of the liquid should be at eye level. The view of the

surface of the liquid will be curved. This curved surface is

called the “meniscus”.

3. Read the graduated cylinder at the bottom of the

meniscus.

TO COMPLETE THE LAB

Complete EVERY station – they do not need to be

completed in order - Neatness counts

After this lab is completed, there is a quiz that covers

lab safety and basic lab tools and skills.

If you finish the lab in class, turn in the page next class

– you can use this activity to help you study.
