The Scientific Method Unit 1
Objectives
What is the Scientific Method? The Scientific Method is the steps and principles that guide scientific questioning and discovery. The Scientific Method provides a standard for scientific discovery. Not all science follows the Scientific Method
Questioning Step 1: Questioning Develop a question that can be tested or investigated for better understanding.
Observation and Research Step 2: Observation and Research Observation – Using your senses to gather information about the world. Your senses are touch, taste, smell, hearing, and sight. Tools, such as a ruler, can also be used to help in observation. Research – Using resources to gain a better understanding of the world around you.
Step 3: Develop a hypothesis Based on observation and, develop a hypothesis by predicting a possible outcome for the question that can be tested or investigated.
Experiment and Investigate Step 4: Experiment and Investigate Experiment – an organized procedure to study something under controlled conditions with variables present Investigate – to examine, study, or inquire in an organized manner, variables not present.
Collect and Analyze Data Step 5: Collecting and Analyzing Data How do scientists collect information? Observing Measuring Types of Data Quantitative – numeric, measurable data Qualitative – descriptive data Organizing Data Graphing Modeling
Drawing Conclusion and Inferences Step 6: Drawing Conclusions and Inferences When drawing a conclusion, you are drawing an inference from collected data. Your conclusion will accept or reject your hypothesis.
Communicating Results Step 7: Communicating Your Results Communicating your results is important in a scientific community. Support your conclusion and be prepared to answer questions and admit experimental/investigational flaws.
