Density of solids and liquids
STARTING QUESTIONHow can I predict whether a solid or liquid will
sink or float when I add it to water?
TestsLook at the data table and listen to teacher’s
verbal instructions and write a summary here
Procedure for Solids
1. Measure the length, width, and height of each of
the solid objects in cm. Record in data table.
2. Calculate volume of solids using formula:
Volume=length x width x height
Record this in data table.
3. Mass each solid on balance in grams. Record.
4. Fill a 250 ml beaker with 100 ml water.
5. Separately, drop each solid in water. Record
whether it sinks or floats.
Procedure for Liquids
1. Zero a graduated cylinder on a balance.
2. Pour in 10 ml of first liquid. Record mass in your
data table.
3. Measure 100ml of water in a 250 ml beaker.
4. Pour liquid into water.
5. Wash out graduated cylinder and repeat steps
1-4 for each liquid. Use the same beaker of
water for each trial.
6. Record whether it sinks or floats in data table.
7. Clean up your lab materials and station.

Sink or Float?
• Before lab, make predictions on the side
whether you think it will sink or float.
