-
Purpose: State the goal - what you want to achieve.
-
Hypothesis: Make an educated guess about the outcome of the experiment.
-
Materials: A list of the items you used.
-
Diagram: A drawing or photograph of the lab apparatus. Label each piece of equipment in the diagram, using a ruler to draw straight lines.
-
Procedure: What you did - a list of numbered steps that you followed.
-
Data: All the measurements and observations you made, displayed in neat tables.
-
qualitative data - any observations (color changes, release of heat, etc.)
-
quantitative data - any measurements you made. Be sure to include the units (g, mL, etc). Record data to the correct number of significant figures.

Data Analysis: Equations, calculations, graphs - work you did with the data
Show the word equations for any formula you use, and then show a sample calculation of the problem.
Graphs:
- Title ("y versus x")
- Label both the x- and the y-axis with the variable and its units.
- Draw the line of best fit. (DO NOT CONNECT THE DOTS)
- Write the equation of the line of best fit on the graph.
-
Conclusion:
- State the result or outcome of the experiment
- State the % error, if there is one.
c. Address the
hypothesis - was it valid or invalid?
d.
Explain possible sources of error.
e. Suggest improvements to the experiment.
IX. Discussion: List five things you learned from the experiment.
