Honors Wrinkle Builder 8/26/13 You must label each of the following as either an observation or a hypothesis: Hedgehogs sleep during the day. If hedgehogs sleep during the day then hedgehogs must be awake during the night.

General Wrinkle Builder 8/26/13 Hedgehogs sleep during the day. Is this an example of a hypothesis or an observation?

THE SCIENTIFIC METHOD Make an observation. Form a hypothesis. Make a prediction. Experiment. Collect and analyze data. Draw conclusions.

OBSERVATION The act of perceiving a natural occurrence. Ex. Hedgehogs sleep during the day.

HYPOTHESIS A proposed explanation for the way a particular aspect of the natural world functions (an educated guess). Ex. If hedgehogs sleep during the day then hedgehogs must be awake during the night. IF & THEN STATEMENT

PREDICTION A statement that forecasts what would happen in a test situation if the hypothesis were true. WHAT WOULD THE PREDICTION BE???

EXPERIMENT Used to test a hypothesis and the prediction. HOW WOULD YOU CONDUCT THE EXPERIMENT??? Control? Experimental? Independent variable? Dependent variable?

CONTROL V. EXPERIMENTAL Control group- is the standard for comparison. (does not receive the independent variable. Experimental group- receives the independent variable.

INDEPENDENT V. DEPENDENT Independent variable- is the variable that is changed or manipulated. Dependent variable- the variable that is observed or measured. (also called responding)

COLLECT & ANALYZE Collect information taken from the experiment and organize it. HOW CAN WE ORGANIZE OUR DATA?

CONCLUSION The hypothesis is either accepted or rejected. Construct a theory! A THEORY IS HIGHLY TESTED!!!

MAKING AN INFERENCE A conclusion made on the basis of facts and previous knowledge rather than on direct observations. So what is the difference between an inference and an observation?
