How can we test these? • Eating chocolate causes zits. • Shaving make hair grow back more. • Drinking coffee will stunt your growth. • The full moon makes people restless. • Reading in dim light damages a person’s eyes.
Scientific Method • Process used by scientists (everyone/anyone) to determine a solution. • “Method” means there is a consistent way of doing something • To determine a solution you must have a problem.
Steps of the Scientific Method • Hypothesis • Data 1. State the problem 2. Gather information about the problem 3. Form a hypothesis Suggested solution to the problem 4. Design/conduct an experiment 5. Gather/analyze data information from an experiment 6. Form conclusion based on data and determine whether hypothesis was correct or incorrect with support data
Experimental Process: Terms of recognition What is an experiment? • An experiment is a test between two or more “groups” • Series of ordered (numbered) steps to test a hypothesis • Terms: 1. Experimental Group • group used to test the hypothesis (changes) 2. Control Group • group which is given “normal” conditions (no change) 3. Variable • the thing that is different between the experimental and control groups – independent and dependent
Which plant is the control group and which plant is the experimental group? Experimental Control
What are the variables for the experimental group? • Independent Variable – changes • sunlight • Dependent Variable – result of the change and what is being measured • Height of the plant • Color of the plant • Etc.
*A THEORY IS A WELL TESTED HYPOTHESIS THAT IS BELIEVED AND ACCEPTED BY SCIENTISTS
Problem A suggested solution to the problem Gathering
