 #1 Ask a question. Observation: Inference: A guess Description of about an object or something you can outcome based on see, smell, touch, your observations taste, hear I ' You can make many NOT an opinion! (must inferences from a be objective) single observation Example: Example: - The ground is wet. - It rained. - Someone was watering the plants. #2 - Conduct background research. Our observations > questions > research defining a purpose Purpose = a statement that clearly shows what question you are trying to answer #3 - Construct a hypothesis. Hypothesis: A testable prediction based on observations that describes a cause and effect relationship between variables Format for a Hypothesis: ''If (IV) then (DV) " IV = Independent variable = Cause DV = Dependent variable = Effect #4 - Test the hypothesis in an experiment. Materials What will you need to conduct the experiment? - Include amounts - Include brands, if important - Be as specific as possible! Write as a bulleted list  #5 - ANALYZE THE DATA.

Make an explicit statement about whether your hypothesis was supported or rejected by your data - Data may/may not support your prediction - Do not change your hypothesis Describe any real world applications/uses for the information learned from the investigation.
