Scientific Method etc.

The Scientific Method is

• a series of questions you ask to solve a problem

• a series of steps you follow to answer a question

• a question you develop to answer a question

• observations inferences and trends in data

A tree is a living thing because

• t has mass and takes up space

• it requires energy and cannot reproduce

• it has cells and can grow and develop

• It has mass and responds to a stimulus

To formulate a hypothesis you should

• make prediction based upon research

• make a detailed materials list

• make a guess at what will happen

• make a data table of our results

A hypothesis is a prediction about what may happen in an experiment. In forming your hypothesis, you must identify the variables in what you want to discover. Which statement below best describes the truth about the independent and dependent variables?

• The independent variable in an experiment is the outcome of the experiment, while the dependent variable is what you are testing.

• The independent variable is the factor in the experiment that is being tested, while the dependent variable is the results of the experiment.

• The independent variable is the factors in the experiment that are kept the same in the experiment, while the dependent variables are the factors that you change.
