Title • Date • U1-6
OHEC = • Observation • Hypothesis • Experiment • Conclude Let’s Break it down!
See something odd. Observation
Make an If…then… statement. Hypothesis
You must identify and control the variables. • If…I.V.…then…D.V.… • Independent variable - Cause • Dependent variable - Effect • You need two groups to compare results. • Control Group – does not get the I.V. • Experimental Group – gets the I.V. • Collect some data. Experiment
The only thing different between the control group and the experimental group should be the independent variable. • Use a large sample to get better results. Control the Variables
Line Graphs = Change over time. • Bar Graphs = Different Groups. Which one is best?
Look at the data to see if your hypothesis was correct. • Write about it. • Identify errors in controlling the variables. Conclusion
Observation • Some students do better on tests than others. • Hypothesis • If______________________________then ___________________________________. • Experiment • Control – • ______________________________ • Experimental – • ______________________________ Example
