The Scientific Method OBM Science Mr. Magner

Good Morning! In your notebook, create (or continue) a page for “Scientific Method” NOTES. Draw your own, then answer the following: According to this diagram, what is the difference between the experimental group and the control group? What DATA is collected, and what observations can we make? Are there any conclusion that we can make?

Experimental Group Control Group

The Scientific Method Scientific problem Hypothesis Test Observe Conclude Theory Your Job: Create ONE page of notes which define the steps of the scientific method. Know the difference between types of variables (independent v. dependent). Completed notes may be used on your first quiz! Incomplete notes may not!

Computer Procedures: Please write down your computer number from the sheet posted in the back. This is your assigned computer. Some will have to share. If there are any issues with the computer, please notify your teacher immediately. Tuck Plugs back in / Plug back in when finished.

How Do We Use Science Every Day?

We must collect information, or DATA in any way possible We must collect information, or DATA in any way possible. What are our five senses? Are there more? What tools do we need?

Science? Engineering? Problem Solving.

“Facts are not science - as the dictionary is not literature” Write this down. What does it mean?

Scientific Problem A problem which can be tested. Information about the problem is collected (data) based on the senses of sight, smell, touch, taste, or sound or some other measurable quantity. It is used to define the problem.

The Aral Sea was once an important fishery and tourism spot. (Click for Video). What led to the decline of the sea?

Hypothesis A tentative explanation for a phenomenon, used as a basis for further investigation “IF – THEN” Statement

Experimentation Procedure that is carried out according to specific guidelines and is repeatable. Independent Variables are factors that can be changed Dependent Variables cannot, but are affected by the independent variable.

Variables What variables might affect the weather that we are having today? Click on the link above to watch a brief video about variables in science. What are the three types?

Variables in Science What does this Graph Show? What Changes on each axis of the graph?  Year

Would you be the first to test out a New Parachute Prototype Would you be the first to test out a New Parachute Prototype? What factors might an engineer consider before they strap you in and push you out of the plane?

Types of Variables Independent Variable - Someone's age might be an independent variable. Other factors (such as what they eat, how much they go to school, What they weigh) aren't going to change a person's age.

Dependent Variables Dependent Variable -A dependent variable is affected by another, typically the independent variable in the equation. The output or outcome of variation is being affected. What are the variables in this picture?

The Control Control– Control variable is the one element that is not changed throughout an experiment. because its unchanging state This allows the student to study the relationship between the other variables, to compare results, and to help refine experiments. Why might we NEED a Control in An experiment? Come up with an Example.

Observations Report and record precise and accurate data. At this step you are simply stating what happened, NOT WHY. New Horizon’s Mission: To observe the far Reaches of our Solar system Pluto when I was 12! What we know now!

Conclusion A statement about the validity the hypothesis, supported with data from the tests that were conducted. Good conclusions state whether or not the hypothesis was valid. What observed data, measurements, or experimental proof supports your conclusion?

THEORY Formulate the simplest general rule that organizes the three main ingredients – hypothesis, prediction, experimental outcome – into a theory.

Prediction You must produce 1 page of notes. Cornell Notes need to include a summary and 4 review questions. Prediction
