1. Aim: How to plot or graph data Dow Now: What are the steps to the Scientific Method. HOMEWORK: ON SEPARATE SHEET OF PAPER OF DATA FROM THE BACK PAGE OF THE WORKSHEET. IN A SENTENCE EXPLAIN THE RELATIONSHIP BETWEEN VOLUME AND PRESSURE. (IS IT A DIRECT OR INDIRECT RELATIONSHIP? WHY?)

2. What is the Scientific Method? “The Road to Knowledge” The Scientific Method is a method of procedure scientist use consisting in observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses. It is a way to ask and answer scientific questions by making observations and doing experiments It is a dynamic process; meaning, there is no definite order to the steps in the scientific method. Scientist jump from one step to another when testing a hypothesis, even formulating a new one.

3. Steps to the Scientific Method Making observations Coming up with a hypothesis and testing it. A hypothesis involves developing an idea or set of ideas that might explain our observations Collect and analyze data. Check results in experiment against your hypothesis: “Do your results agree with your hypothesis?” Start over if you need to.

5. Graphing and Analyzing Data Identify dependent and independent variables Dependent variable – the variable that is being observed during an experiment. Independent variable – the variable that is being changed during an experiment Labeling the graph Title the graph Label the y-axis (dependent variable) and x-axis (independent variable) Direct relationship; “as one variable increases, the other variable increases” or “as one variable decreases, the other variable decreases” Indirect or inverse relationship; “as one variable increases, the other variable decreases” or “as one variable decreases, the other variable increases”
