Step 1: Observation Collect with 5 senses Describes specific Events Examples: (from class) ********** Inference: based on 5 senses and previous experiences Examples (from class)

Step 3: Hypothesis “ Educated Guess” Best if written as an: “IF ” “THEN” statement Ex: IF I study my homework, THEN I will pass the test. Ex: IF I shake the solution, THEN the color will change.

Step 4: Experiment Step by step instructions To TEST something unknown.

Parts of Experiment: Subject: person/thing being tested example: Procedure: detailed steps. Repeatable example: Constant :NEVER change. Same in all. example: Control: Used for comparison. The “Norm” example:

Variables in the EXPERIMENT Independent The ONE thing that is changed in the experimental set-up. example: Dependent The thing that is MEASURED in the experiment. example:

Step 5: Gather Data The observations, facts, information gathered from running the experiment. “State it, but DO NOT explain it”

Types of Data: Quantitative Numbers Usually require the use of tools Examples : Qualitative Observations How it: smells tastes looks feels sounds Examples :

Step 6: Conclusion “Wrap it up” Explain results Check to see if the hypothesis is correct. Includes RESEARCH ! Mentions problems/mistakes Step 7: Verify Must always retest the data. To double-check to see if experiment is VALID.
