1. The Scientific Method

2. Seven Steps of the Scientific Method
State the Problem
Collect Information
Hypothesis
Test the Hypothesis
Observe & collect data
Results
Conclusion

3. State the Problem What you want to know?
Ex: Which liquid will heat to 70° quicker water, molasses or jello?

4. Collect Information Gather as much information as possible.
Ex. We went to internet site to see which object would absorb heat faster

5. Hypothesis Educated guess/Prediction/What you think will happen
Ex. I think water will boil faster because its molecules are not as closely packed together.

6. Test the Hypothesis Experiment Our experiment
Place 3 different substances on the stove
Place a thermometer in each substance
Wait & observe temps at different times

7. Identify b) Depending variable Independent variable
• The variable that I change
Ex. Types of substances water, jello, molasses
b) Depending variable
• What your measuring/the measurement
Ex. Temperature of different substances
c) Control in the experiment
• Our comparison/item that gets no treatment
Ex. 3 samples that don’t get heated just leave them
d) Constants in the procedure
• Things that are kept the same
Ex. Same stove, same pot, same
size/amount of samples, same eye on
stove

8. Observe & Collect Data
Watch experiment and collect data in a chart *only your data

10. Conclusion Tell if your hypothesis was right or wrong
Ex. My hypothesis was right because water reached 70° first.
