SCIENTIFIC METHOD A WAY TO SOLVE A PROBLEM
SCIENTIFIC METHOD SERIES OF STEPS THAT A SCIENTIST WILL USE TO SOLVE A PROBLEM.
STEPS OF SCIENTIFIC METHOD 1.DETERMINE THE PROBLEM– WHAT ARE YOU STUDYING? 2.GATHER INFORMATION – USE SENSES, RESEARCH MATERIALS 3.FORM A HYPOTHESIS – MAKE AN EDUCATED GUESS
SCIENTIFIC METHOD 4.EXPERIMENT – TEST HYPOTHESIS— CONTROLLED EXPERIMENT. 5.RECORD & ANALYZE– COLLECT DATA 6.CONCLUSION – IS HYPOTHESIS CORRECT OR NOT?
CONTROLLED EXPERIMENT AN EXPERIMENT IN WHICH ALL CONDITIONS ARE THE SAME EXCEPT FOR THE ONE BEING TESTED.
VARIABLES INDEPENDENT VARIABLE – FACTOR BEING TESTED IN THE EXPERIMENT (X –AXIS) DEPENDENT VARIABLE– RESULTS FROM CHANGE (Y-AXIS)
CONTROL-- STANDARD FOR COMPARISON GROUP GIVEN NO TREATMENT CONSTANTS PARTS OF THE EXPERIMENT THAT ARE KEPT THE SAME EX: LIGHT, WATER, SOIL, PLANT
LACK OF VIT. A IN DIET WILL CAUSE LIVER CANCER IN RATS GROUP A – CONTROL GROUP RATS (12) WATER AIR LIGHT REGULAR DIET GROUP B- EXPERIMENTAL GROUP RATS (12) WATER AIR LIGHT DIET LACKS VIT. A
ANALYZE RESULTS DO THE RESULTS SUPPORT THE HYPOTHESIS? WHAT TO DO NEXT?
Controls and Constants
The scientific method is an organized way to solve a problem
