SCIENTIFIC METHOD LAB REPORT RUBRIC
1. Title (5 pts): “The Effect of (A) on (B)” Example: The Effect of Hydrogen Bonding on Water Cohesion
2. Introduction (10 pts)
a. Background Tell me what you already know about the main subject of the lab. Introduce the lab and explain why you are doing it and what you hope to learn. b. Hypothesis Your educated guess about your results. MUST be in “if/then” format
Example: If I increase the temperature of the reaction, then the reaction will go faster.
3. Materials and Methods (20 pts) a. Materials: List the materials used in the experiment. b. Methods: Describe the procedures in sufficient detail so that others can repeat your research. This must be a numbered, step by step list of exactly what you need to do!
4. Results (30 pts)
a. Dependent Variable: What are you measuring? This is your dependent variable. It could be temperature, time, volume, etc. Make sure you tell me what units you are measuring it in. Example: The dependent variable is the rate of the reaction, measured in seconds.
b. Independent Variable: What are you manipulating or changing? Include units! Example: The independent variable is the pH of the milk at integer values from pH 4.0 to pH 12.0.
c. Confounding variables (Constants) What things are you keeping the same throughout the experiment? Be thorough. Example: The same test tubes, water droppers, water, thermometers, water baths, beakers, test tube racks, gloves, and pH test strips are used for all parts of the experiment.
d. Replication: How many times did you repeat the experiment?
e. Controls: The control is what you are comparing your results to. Example: The water at pH 7.0 was the control. We compared our results to this control to see if substances were acids or bases.
f. Organize Data: Organize the collected data in a data table. Provide a title for your data table. Include units!
g. Data Analysis Present the data in a graph: independent variable (x-axis) vs. the dependent variable (y-axis) in the appropriate graph form (line vs. bar) with proper X and Y-axis labels, keys, and numerical scales.
5. Conclusions (30 pts) a. Discuss your results. Tell me what happened and why, and what this means. b. Discuss whether the hypothesis was supported or not supported (refuted) by the data. c. Relate your conclusions to the concepts learned in class. d. If the results are unexpected or contradictory, you should attempt to explain and point out possible avenues for further research, including possible sources of error.
6. Literature Cited (5 pts) Include all published works consulted in your research. List in bibliographic form. You must cite at least one source (for example: your textbook, your lab packet, or class notes) SCIENTIFIC METHOD LAB REPORT RUBRIC
