1. WHAT IS THE SCIENTIFIC METHOD?

2. Scientific Method – Logical steps to solve a problem
Scientific Method – Logical steps to solve a problem. This may vary in the number of steps.

3. Solve a problem with Scientific Method and Design an experiment …
You own a trucking company and have to transport a series of gasses and need to determine which gases are flammable. (Air, Helium, Hydrogen, CO2)
Steps 1-3…what would they be?
Step 4- Design an experiment…
Step 5- What do we conclude, and how?

4. 1) State the Problem A question about science is asked through observations. Ex. Why did the dinosaurs go extinct 65 million years ago?

5. 2) Gather Information (research) Information about the problem is collected, usually through measurements.
Ex. Measure the amount of meteorite rock in 65 million year old rock layers – (Iridium – element found in meteors)

6. 3) Form a hypothesis. Ex. Gaia hypothesis
Gaia video

7. Ex. A giant meteorite crashed into the earth 65 million years ago

8.   4) Test the Hypothesis Conduct an experiment with a control and a variable
What is a control?
What is a variable?

9. Ex. Simulate the climate 65 million years ago.

10. 5) State a conclusion Determine whether or not a hypothesis is correct.
Ex. There is no proof that a meteorite was responsible, however, it is possible.

11. Theory – A hypothesis or series of hypotheses that are supported by the results of experiments and observations.

12. Ex. Big Bang – Creation of the Universe

13. Scientific law – An established theory.
Ex. Law of the conservation of energy
