Final answer:
The 7 S's in order for a scientific investigation are making observations, asking a question, forming a hypothesis, setting up a controlled experiment, collecting and analyzing data, drawing conclusions, and communicating results. Each step is necessary to ensure a logical and systematic approach to understanding the world and testing hypotheses.
Step-by-step explanation:
The 7 S's in order for a scientific investigation are as follows:
- Making Observations: It all begins with making observations. This is when scientists use their senses to gather information about the world around them.
- Asking a Question: After making observations, scientists often generate questions based on their observations. These questions help guide their investigation and focus their research.
- Forming a Hypothesis: A hypothesis is a possible explanation or answer to the question being investigated. It is based on prior knowledge and observations.
- Setting up a Controlled Experiment: A controlled experiment is used to test the hypothesis. It involves manipulating an independent variable and measuring the effects on a dependent variable, while keeping all other variables constant.
- Collecting and Analyzing Data: During the experiment, data is collected and recorded. This data is then analyzed to determine patterns, trends, and relationships.
- Drawing Conclusions: Using the analyzed data, scientists draw conclusions about the hypothesis. They determine whether the data supports or refutes the hypothesis.
- Communicating Results: Lastly, scientists communicate their findings to the scientific community and the general public through publications, presentations, or other forms of sharing.
Each step is necessary for an investigation because they help ensure a logical and systematic approach to understanding the world and testing hypotheses. For example, making observations provides the initial information needed to formulate a question, and setting up a controlled experiment allows for the rigorous testing of a hypothesis.
