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:

How can you organize Data? • CHARTS • GRAPHS

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.
