CHAPTER 1 INTRODUCING THE SCIENTIFIC METHOD Scientists solve problems using the scientific method It’s a step-by-step process that all scientists scientists try to follow Scientists start by finding out as much as possible possible about a problem Then they make a hypothesis hypothesis They test the hypothesis with an experiment Then they analyze the results or the data to see if the hypothesis was right If the experiment does not support the hypothesis they think about the problem again and develop a new hypothesis They then test that hypothesis with a new experiment If the experiment supports the hypothesis other scientists repeat the experiment to make sure that they get the same results If they do get the same 4
Scientific method ask question collect information make observations form a hypothesis record and analyze data draw conclusions conduct experiment develop new hypothesis try again experiment supports hypothesis experiment does not support hypothesis communicate results The scientific method is the process scientists follow to solve problems Scientists conduct experiments and carefully carefully record analyze and evaluate the data results the hypothesis is accepted as true until it can be proven false 5 VOCABULARY Scientists use the information they learn from testing many hypotheses Scientific theories are explanations for hypotheses to develop scientific why things work or scientific theories A theory how things happen
