Please get your science notebook from off the table before we start class. Seat down in your seat and turn to the warm-up section (back of book). On the first line write: August 11 – Animal Tracks

Observations Any information collected with the senses. Quantitative – measureable or countable 3 meters long 4 marbles 50 kilograms 35 degrees Celsius Qualitative – describable, not measureable red flowers smells like fresh baked cookies Tastes bitter The skill of describing scientific events

Inference Conclusions based on observations. The process of drawing a conclusion from given evidence. Practice: Observations: I hear people screaming I smell cotton candy, popcorn, and hamburgers I see a lot of people Inference = ?

Look at these two sets of animal tracks. List 3 OBSERVATIONS Warm-Up August 11 Look at these two sets of animal tracks. List 3 OBSERVATIONS (What do you see? (Write it down next to the heading.) August 11 – Animal Tracks Observations: 1) 2) 3) Inference: Make an INFERENCE (What do you think happened? Write it down.)

Now what do you think happened? (Write it down.) Make 3 OBSERVATIONS Make an INFERENCE

Now what do you think happened? Did your revise (change) your original inference? How did seeing the whole image change your mind? How does this activity relate to what a real scientist does in an experiment?

Standards S6CS8. Students will investigate the characteristics of scientific knowledge and how it is achieved. S6CS9. Students will investigate the features of the process (procedure) of scientific inquiry.

The Scientific Method The scientific method is the only scientific way accepted to back up a theory or idea. This is the method on which all research projects should be based. The Scientific Method is used by researchers to support or disprove a theory.

PHEOC The Scientific Method The Scientific Method involves 5 steps: Problem Hypothesis Experiment Observation Conclusion (Result) PHEOC

The Scientific Method Problem- You ask a question about what you observe.

The Scientific Method Hypothesis- You predict what you think the answer to your question might be.

The Scientific Method Experiment- You figure out a way to test whether the hypothesis is correct. The outcome must be measurable. Record and analyze data.

Controlled Variable: Something that you don’t change. Dependent Variable: Something that you measure. Independent Variable: The object you experiment with.

The Scientific Method Observe - You do the experiment using the method you came up with and record the results.

The Scientific Method Conclusion- You state whether your prediction was confirmed or not and try to explain your results.

Scientific Method Review Closing: Scientific Method Review See if you can identify the steps of the Scientific Method in the following scenarios. Work with your lab group. Don’t yell out the answer; raise you hand instead.

Scenario 1 Peter loves music.  He believes that he does his homework better and faster when he listens to music.  His parents say that music is distracting when studying.   What is the problem? Create an hypothesis. How would you test your hypothesis?

Scenario 2 The Johnson family has decided to try to save electricity (and money at the same time). They were told that they could replace their regular light bulbs with special fluorescent bulbs that use less energy.  They wonder if it is really worth doing. What is the problem? Create an hypothesis. How would you test your hypothesis?

Scenario 3 Kelly and Jack are playing in the park. Jack rolls a marble down the small playground slide. Kelly rolls a marble down the large playground slide at the same time. They noticed that Kelly’s marble reached the ground first. They rolled the marbles again and noticed that the same thing happened. What is the problem? Hypothesis? How would you test your hypothesis? What would by your Controlled Variable? (What you would keep the same? What would be your Dependent Variable? (What would you measure?) Why does one marble roll faster than the other one? Roll both marbles down the slide at the same time. Size of the marbles, same slide, roll at the same time. The time the marbles reached the ground.
