Station 1: Triple Beam Balance

Station Objective: Students will learn to accurately measure the mass of an object using a triple beam balance

Directions: Use the triple beam balance to determine the mass of each of the following objects. Every measurement should have 1 decimal place and be followed with a g symbolizing that the measurement was taken in grams.

A. Tongs

B.Test Tube Tongs

C.Crucible

D.Crucible Lid

E.Clay Triangle

F.Watch glass

G.Evaporating Dish

Place these items and their measurements in a data table.

Station 2: Measuring Volume

Station Objective: Students will learn to accurately measure the volume of a liquid using different equipment

Directions: Use the equipment provided to follow the directions in each of the steps below. Do NOT pour out the water until told to do so!!!!

A.Measure 1milliliter in the graduated pipette and squirt the water in the pipette into the 10mL graduated cylinder.

B.Fill the 100mL beaker up to the 80mL line with water from the tap.

Add the water from the graduated cylinder to the 100ml beaker.

C.Pour the water out of the beaker into the 100mL graduated cylinder. What do notice about the water in the graduated cylinder? Did it end up being more than, less than, or equal to 80mL? Which piece of equipment more accurately measures the volume of a liquid a beaker or a graduated cylinder?

D.Add 50mL of water from the tap to the Erlenmeyer flask.

E.Fill the volumetric flask to the line on the neck.

F.Add the Erlenmeyer Flask (D) and the volumetric Flask to a buret. Allow 5.5 ml to escape. How much water

remains in the buret?

Place the answers to this section in a data table labeled data table II.

Station 3: Setting Up a Water Bath

Station Objective: Students will learn to set up a water bath

Directions: Follow the steps below to set up a water bath. Leave the water bath set up until it is checked.

A.Attach rubber tubing to the Bunsen burner, then connect it to the gas jet. Do NOT turn on the gas jet!!!!

B.Attach the ring clamp to the ring stand.

C.Attach the test tube clamp to the ring stand above the ring clamp.

D.Place the wire gauze on the ring.

E.Put 300mL of water in a 400mL beaker.

F.Place the beaker on the gauze.

G.Put a test tube in the test tube clamp and lower it into the beaker of water.

H.Measure and record the temperature of the water in Celsius

I.Convert the Celsius temperature into a Kelvin temperature (record this value). (If you don’t know how to do this you may have to use a book for reference,)

J.Draw a picture of the water bath setup.
