Lab Reports
Chemistry lab:
title
purpose
procedure
observations
determine if chemical or physical change; if chemical state evidence
Creek analysis
data measured and overall quality calculations
flow rate data and calculations
Measurement/Density
Title
Purpose
Procedure
Data collected: Table from prediction activity
mass and volume measurements for metals and water
Data analysis: density calculations, averages for class (for metals), %
error for metals and for the water (you should have 5 total), standard
deviation for water, the known value of water is 1.00 g/mL
Bar graph for the metal densities and line graph for water.
Conclusion statement should include an accuracy statement and a precision
statement.
Blood Spatter
Title
Purpose
Background information (see links for information on blood spatter)
Identify variables
procedure (remember we made changes to # 5 and 6)
data table with height, diameter, description, and diagram of blood spatter.
line graph
prediction of unknown height
% error (your prediction is the experimental value and the actual height is
the accepted value).
Conclusion should include an accuracy statement
Candy lab
Title
purpose
predictions
procedure
data table
calcuated % and degrees for each color
graphs: bar, scattered plote and pie graphs
conclusion statement: do results support your predictions?
conclusion
Rocket lab:
Rough design and the final design (on graph paper, neatly drawn using
straight edges).
Data collected: times, angles
Data analysis (calculations): Average time, average angle, determine height
using the tangent of the average angle.
Motion lab:
Purpose
Procedure: part 1,2,and 3
data collected (preferably in data tables): Part 1: times for each walk
Part 2, three times for each trial
Part 3: lengths and three times (for each length)
Calculations/graphs: part 1- average speed: 10/time, line graph for each
person
part 2: 4 average times, 4 average speeds, 4 final speeds, 4 acclerations
part 3: 4 average times, 4 gravities, average gravity, s.d for gravity, %
error
conclusions: Possible sources of error, accuracy and precision statements.
Astronaut Bob lab:
Purpose
Identify variables
procedure
data collected mass and times
data analysis: average time and line graph of time vs. mass
determine astronaut bob's mass
When given actual mass,determine % error
Conclusion: accuracy statement.
