DENSITY LAB
Density is considered to be the amount of mass packed into a given space. If more mass
is packed into a space, then the mass becomes denser. Density is calculated by using the
formula: DENSITY = mass ÷ volume. Fill in the objects in the data table below. Use
your knowledge of measurement to see which one has the most “stuff” packed into a
given space.
**REMEMBER, RESTATE THE QUESTION, BE DETAILED, AND USE COMPLETE SENTENCES**.
PRE-LAB INFORMATION
1. Identify the independent variable (IV).
2. Identify the dependent variable (DV).
3. Write a hypothesis for this experiment.

POST-LAB QUESTIONS --- (USE DATA!)
**REMEMBER, RESTATE THE QUESTION, BE DETAILED, AND USE COMPLETE SENTENCES**.
1. Place the items of the experiment in order from least dense to most dense.
2. Identify three conditions that should be kept constant in this experiment.
3. Explain whether the results of the experiment support or do not support your
hypothesis. Use specific data to justify your answer.
4. Describe 2 possible errors in the way the experiment was set up or performed.
5. Based upon the data, which of the objects is the closest to being able to float AND
how do you know? Explain clearly and in detail.
