Measuring Density Directly and Indirectly
Introduction: 20 Points
-
-
Background (1-1½ pages)
o What is Density?
 Formula D=m/v
 Talk about what density is
 Talk about what mass is
 Talk about what volume is
o Direct and Indirect Measurement
 Define Direct Measurement and discuss how it is used (in relation to this lab)
 Define Indirect Measurement and discuss how it is used (in relation to this lab)
o History of Density
 King Hiero
 Archemedies
 Gold Crown
Purpose (1-2 sentences)
o What is the purpose of this lab?
Hypothesis (1 sentence)
o What do you believe will happen (In statement form)
o DO NOT USE PRONOUNS (The hypothesis for this lab is…)
Methods and Materials: 20 Points
-
You should have TWO Procedures
o First procedure (sponge part)
 Include materials: sponge, ruler, electronic scale, scissors
 Describe the procedure in paragraph form. Remember, it should flow together like a
story, not a list of steps.
o Second procedure (metal objects)
 Include materials: metals (four different), electronic scale, graduated cylinder, water
 Materials and procedure should flow smoothly
Results: 20 Points

Quantitative Results (Part 1)
o The Data Table for the first procedure (page one) should be typed up and included
o The calculations for Volume should be included (either typed or neatly hand-written)
 The four steps should be shown:
 Define known and unknown quantities
 Write the correct formula
 Substitute the numbers (with units)
 Solve and round off answer
o The calculations for Density should be included (either typed or neatly hand-written)
 Follow the four steps of solving equations
Qualitative Results (Part 1)
o These are your results in words. Write a brief paragraph saying what is happening to mass, volume and
density as you continue to cut the sponge in half. Just say what is happening, not why it is happening
Quantitative Results (Part 2)
o The Data Table for the second procedure (page 3) should be typed up and included
o The calculations for volume should be included (either typed or neatly hand-written)
 Follow the four steps of solving equations
 Volume = final volume – initial volume
o Include Percent Error Calculations for each of the four metals
 Follow the four steps of solving equations
Qualitative Results (Part 2)
o These are your results in words. Write a brief paragraph stating the mass, volume and density of the four
metals. Just say what is happening, not why it is happening
Discussion: 20 points
-
Clear explanation that refers to data in part one
o Discuss why what happened to the sponge in the first part happened
o What does this tell you about density?
- Clear explanation that refers to the data in part two
o Did each of the metals have the same density? Why or why not?
- Percent Error
o Which metal(s) did you find to have error?
 What could be the reason for this error?
 What would you do differently next time to reduce error?
 Should the results from this lab be trusted? Why or why not?
Reference: 5 Points
-
Include a References page that is SEPARATE from the rest of the lab
Include IN-TEXT Citations ESPECIALLY in your Introduction
Use APA Format
DO NOT PLAGIARIZE (It will result in an automatic zero and an honor code violation)
Neatness/Grammar/Formatting: 10 Points
-
Use proper grammar
Double-Spaced, 12-point Times New Roman Font
Use proper lab report format
