Density of Liquids Lab
Title/Name: 5 Points
-Same format as last lab
Introduction: 20 Points
-Background
- A lot of you were confused about density, talk about how objects can be identified by their density and how every substance has a specified density
- What is water?
- Include its Biological Importance
- Why is the density of water so important?
- What is Glycerin?
- What is it?
- What is it used for?
- What is Canola Oil
- What is it?
- What is it used for?
-Purpose
- Measure the densities of three unknown liquids
- Identifying the unknown liquids based on density
-Hypothesis
- Clear statement about what you believe will happen (Your Theory)
Methods and Materials: 20 Points
-Procedures explained clearly in paragraph form
- DO NOT GIVE ME A LIST OF PROCEDURE STEPS
-Materials included in the aforementioned paragraph
- DO NOT GIVE ME A LIST OF MATERIALS
Results: 20 Points
-Include Table 1: Data for Liquids from page 2
-INCLUDE ACTUAL NUMBER CALCULATIONS FOR DENSITY
- Use proper units:
- Mass=grams
- Volume=milliliters
- Density=grams/milliliter
-Include Table 2: Predicted and Actual Density Column Results
- Predicted Order of Liquids
- Actual Order of Liquids
-Include PERCENT ERROR CALCULATIONS
- For Liquid A
- For Liquid B
- For Liquid C
Discussion: 20 points
-Explain your Results, this is the WHY portion of the lab
- Explain WHY the density column looked the way it did
-Why might have the results not coincided with your data and calculations?
- What are some possible sources of error?
-Is your percent error high or low?
- Did your errors cause you to predict incorrectly?
-What could you do in future experiments to limit error?
-Accept or Reject Hypothesis
-Conclusion
- What did you learn about from this lab?
