EQ: How do scientists obtain their knowledge?

Scientific Method

1.ObservationsWhat do you see that you could question?ex. Great white sharks can jump out of the water Water comes out of a faucet

2. Background Research What is already known about great whites What is known about how a faucet works

3. Questions What do you want to know?

4. Hypothesis What is my educated guess to my question? Written as an “if/ then” statement ex. If Great white sharks can jump out of

the water, then bull sharks can also jump out of the water.

If I open the faucet up all of the way, then a lot of water will come out.

5. Experiment a. Types of experiments 1) Qualitative- information collected is

not measurable 2) Quantitative- information collected is

measurable b. Experiment process 1) Materials

What is needed to perform the experiment? 2) Procedures

Should be written in a step by step manner

c. What is tested – Variables 1) independent- that being tested

2) dependent- the result 3) control

6. Data What information was collected? Table of organized information 7. Results A summary of the data in written format.

8. Conclusion How do your results from the experiment relate

to your hypothesis? Where do you think any errors occurred in

your experiment? What would you do differently when repeating

this experiment?

9. Application How could you use the information

from the experiment?
