Learning Goal 10L
Learning Goal 10L: I can plan and implement safe investigative procedures, including developing hypotheses, selecting equipment, collecting data, organizing data, analyzing data, and communicating valid conclusions.
Learning Criteria
1. I can create testable hypotheses that "takes a stand" in a particular direction.
For example: If I was investigating the relationship between density and mass, I might create the following hypothesis: "I believe that copper samples with different masses will have the same density.
2. I can select equipment that is appropriate for the type of data that I wish to collect.
For example: If I was investigating the density of an irregularly shaped object, I would choose to use a graduated cylinder to measure the volume, and an electronic scale to measure the mass.
3. I can record data that is appropriate for my experiment. This includes measuring to the correct number of significant figures and always recording the appropriate units with my measurements.
For example: I always record the "known" digits of a measurement plus one "guess" digit and follow the values with a unit. i.e. 32.0 g.
4. I can organize data in a clear and easy to read format.
For example: I might organize the data from a density experiment as shown below.

5. I can analyze data by performing appropriate calculations and creating relevant graphs.
For example: I might represent the density of aluminum by creating a mass vs volume line graph.

6. I can develop and write logical, organized conclusions that summarize my experiment and state the relevance of my data.
For example: I might include the following information in the conclusion to my investigation: 1. Restated hypothesis or purpose 2. Brief summary of the procedure 3. Brief summary of the results 4. Interpretation of the results.
