1. Scientific Method A blueprint for experiment success.

2. What is the scientific method? It is a simple method scientists use to conduct an investigation. It is a way to ask & answer scientific questions by asking questions & conducting experiments.

3. I. Question/Problem Ask a question about something observed. –Why? –How? –What? Question to be solved. –Must be about something measurable.

4. II. Hypothesis Educated guess about how things work. Prediction Use If, then statements –If ____ [I do this], then _____ [this will happen] Focus on one variable only.

5. III. Experiment Tests your hypothesis. Is it accepted (right) or rejected (wrong) ? Change only one variable at a time. Use a control or control group ( A group that has nothing done to it. Standard used for comparison in an experiment.) In order for results to be valid, conduct several tests.

6. IV. Conclusion Summary of your experiment. After your experiment, analyze your data to see if your hypothesis was accepted or rejected. If hypothesis is rejected, g ive possible reasons for the difference between your hypothesis and the experimental results.

7. Materials What are materials? –Any supplies you need to do to conduct an experiment

8. Procedures What are procedures? –Are a list of steps that scientists must use to conduct an experiment.

9. Data Collection Data collection- is process of collecting data and recording it to later analyze

10. Analyzing What does analyzing mean? –This is when you look over data that you have recorded and try and come up with answers from those numbers or observations.

11. Experimental Design Experimental Design- is the design of any information- gathering exercises where variation is present, whether under the full control of the experimenter or not.
