Viscosity Lab Writeup
This lab write up is due on Tuesday, Dec. 15th. It is
worth 50 points in the assessment/project
category of your grade (30%). For each day it is
late, I will deduct 5 points up to 25 pts.
This lab write up MUST be in your lab composition
book. If I see GIG’s or notes in your book, I will not
grade your lab.
You MUST add this lab to your table of contents at
the beginning of your book. I will be checking!
Title
Date Lab #3
Introduction (10 pts.)
This section is to be written in paragraph form and
needs to be 2 or more paragraphs.
This section includes background information, purpose
of lab, and scientific question.
You need to account for the independent and
dependent variables.
Hypothesis
(5 pts.)
This section needs to be written as an If… Then…
statement.
Do NOT use first person.
Materials (2.5 pts.)
This section should be written in sentence form and
name ALL the materials used.
The materials used include….
Methods (2.5 pts.)
This section includes the step-by-step procedures used.
Number the steps:
1.
2.
3.
The procedure should be thorough enough that someone
could repeat the experiments and get the same results.
Results (15 pts.)
This section includes all your data. For this lab, you should
include the data table from your worksheet with all
measurements of time for each of the fluids tested. Be
sure to label it with a title and include units! Find the
average times and rank the fluids according to their
viscosity.
Results contd.
This section also includes questions and answers.
Write out EACH question and underline it. Then
answer in a complete sentence.
Discussion/Conclusion and Error Analysis (15 pts.)
This is the most important part of your report, because
here, you show that you understand the experiment
beyond the simple level of completing it!
Your conclusion MUST CONTAIN YOUR SUPPORTING
DATA! Use actual data to explain your conclusion, and
tell why your data is significant with regards to viscosity
and volcanoes. Be sure to tie it all in with volcanoes.
This is where you give details of your observations and
explain why you think you got your results.
Discussion/Conclusion and Error Analysis contd.
Be sure tell the significance of your results.
Restate your original hypothesis and explain whether
your data supports your hypothesis or not. If not, then
explain why you think it doesn’t.
Explain possible experimental errors—factors that you
think may have affected your results.
