Scientific Method

Scientific Method

1. Making an Observation • Must know something is happening/going on • Sight, hearing, taste, touch, smell may be used to do this

2. Asking a Question • This focuses the purpose of the investigation

3. Forming a hypothesis • This step is done after observations and asking questions • Is a possible explanation or answer to a question • Must be testable

4. Testing the hypothesis • This helps to determine if hypothesis was good or bad • Will contain factors called variables • Information acquired during this step is known as data

5. Analyzing Results • This step is done after collecting and recording data. • Information may be made into charts, graphs, or reports in this step

6. Draw Conclusions • This is done at the end of an investigation • Results will either support, or NOT support the hypothesis • May decide to experiment again or form a NEW hypothesis

EXAMPLE: • Remember the steps: • Make an observation • Ask questions • Form a hypothesis • Test the hypothesis • Analyze results • Draw conclusions
