READING LAB EQUIPMENT
RULE: Always read lab equipment one place value past the decimal value that you see!
EXAMPLE 1:
Ruler A: you can read to the tenths, so you estimate the hundredths
Length of nail when measured with Ruler A: _____4.35cm____5 is your guess digit______
Ruler B: you can read to the ones, so you estimate to the tenths
Length of nail when measured with Ruler B: _____4.4cm _____4 is your guess digit ___
EXAMPLE 2:
Ruler A:
40 cm
Ruler B:
50 cm
40 cm
41 cm
Ruler A: you can read to the ___tens_________, so you estimate to the ____ones__________
Length of the line when measured with Ruler A: _______48cm ________________________
Ruler B: you can read to the ___ones_________, so you estimate to the __tenths____________
Length of the line when measured with Ruler B: _______40.8cm _______________________

Station 4
A. MASS
1. Bring a pencil and a calculator to the table.
2. Predict the masses of each object in grams.
3. Use the electronic balance to determine the mass of each object. Record the mass in the data table below.

B: VOLUME
1. Take the empty cup. Using the cup, try to obtain 75mL of water from the sink.
2. Transfer the water to the graduated cylinder. How did you do? Record the results in the data table.
3. Try obtaining 200 mL of water from the sink and record results.

Station 5
1. There are three cups of water – one dyed blue, one dyed green and one dyed red – on the lab table. Transfer
each sample of liquid to the smallest graduated cylinder on the table that will hold all of the water.
2. Read the graduated cylinder. Record the volume of water in each cup in the data table. Then return the water
to the cup.
