Procedures

Station 1: Measuring the height of your teammates

1. Use the meter sticks to measure the height of everyone on your team; in meters

2. Use the conversion table to convert their heights from meters to kilometers, centimeters, and micrometers.

3. Record the data

4. Clean your station.

Station 2: Identifying the physical properties of matter

1. Tare the mass of the weighing tray #1 and measure the mass of substance #1.

2. Record the mass and the other physical properties listed (ie. color texture, hardness, and odor).

3. Place substance #1 in the appropriate vial.

4. Repeat steps 1-3 for the remaining substances.

5. Wash your hands and clean the workstation.

Station 3: Understanding density

Use the graduated cylinder to measure 10mL of liquid #1 and place it into the beaker.

Repeat step 1 for the reaming liquids.

1. Draw and label the picture of the liquids inside the beaker.

2. Discuss the relative densities of the liquids (rate them in the increasing order)

3. Pour the contents down the drain.

4. Clean your station in its entirety.

Station 4: Measuring the densities of liquids

Measure 10 mL of Liquid #1 in the respective beaker (remember to tare the mass of the beaker first).

1. Record the mass and volume of the liquid on the data table

2. Calculate and record the densities of the liquids using the following equation:

Density = mass/volume.

3. Pour the contents down the drain and clean the beaker for the next trail.

4. Repeat steps 1-4 for the remaining liquids.

Station 5: Chemical or Physical Change

1. Measure 1.0 grams of substance 1 in beaker number one (remember to tare the mass of the beaker).

2. Combine 10 mL of water with the substance and stir.

3. Make observations and determine if the substance underwent a chemical or physical change.

4. Repeat steps 1-3 for substance 2 in a separate beaker

5. Combine substance 1 and substance 2 together record observation

6. Clean up your area.

Station 6: Measuring the densities of objects

1. Measure the mass of object 1 and record the data in the table

2. Calculate the volume of the object, using the formula volume = length x width x height.

3. Calculate the volume of the object using the equation: Density =mass ( volume.

4. Repeat steps 1-3 for the remaining objects.

Station 7: Equipment (How things are measured)

1. Identify the laboratory equipment

2. Fill in the chart

Station 8: Measurement (following directions)

1. Follow the directions on the sheet to make a cup

2. Attach cup to paper

Station 1: Measuring the height of your teammates
