Q. Which of the following correctly compares a scientific investigation to a demonstration? An investigation is a process of answering a question; a demonstration shows how something happens. A demonstration is a process of answering a question; an investigation shows how something happens.
What is the difference between a science experiment and an investigation?
Investigation: A method of answering a question by observations , including modelling, researching and collecting data. ... Experiment: A controlled method of answer a question by forming a hypothesis, running fair tests by controlling only one variable at a time. Follows the scientific process.
How would you describe a scientific investigation?
A scientific investigation is a plan for asking questions and testing possible answers . A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.
What are 3 scientific investigations?
Scientists use three types of investigations to research and develop explanations for events in the nature: descriptive investigation, comparative investigation, and experimental investigation .
What are the four types of scientific investigations?

What is meant by the term experiment?
1 : a procedure carried out under controlled conditions in order to discover an unknown effect or law, to test or establish a hypothesis, or to illustrate a known law. 2 : the process of testing : experimentation. experiment.
How do you conduct a scientific investigation?
- Define a Question to Investigate. As scientists conduct their research, they make observations and collect data. ...
- Make Predictions. Based on their research and observations, scientists will often come up with a hypothesis. ...
- Gather Data. ...
- Analyze the Data. ...
- Draw Conclusions.
What is experiment scientific method?
In the scientific method, an experiment is an empirical procedure that arbitrates competing models or hypotheses . Researchers also use experimentation to test existing theories or new hypotheses to support or disprove them.
What are the key elements of scientific investigation?
It’s characterized by six key elements: questions, hypotheses, experiments, observations, analyses, and conclusions . These elements are interrelated steps, so they don’t always function in the same order.
What are types of investigation?
- Theft of Trade Secrets.
- Workplace Violence.
- Workers Compensation Claims.
- Integrity Checks.
- Security Evaluations.
- Undercover Operatives.
- Sexual Harassment.
- Secret Shoppers.
What is a comparative scientific investigation?
Comparative Investigation: Involve collecting data on different populations/organisms, under different conditions (ex. Times of year, locations), to make a comparison. Example – Using a hand lens to examine the color and texture of four different rocks.
What is scientific inquiry examples?
A statement outlining what you are trying to find out or a question to guide your investigation. Examples: • To determine how four fertilizers affect the growth rate of bean plants . How will four fertilizers affect the growth rate of bean plants?
What are the five types of scientific investigations?
Scientists use different methods of investigation in different circumstances. These methods include (in no particular order) fair testing, identifying and classifying, modelling, pattern seeking, and researching.
Which type of investigation is used to compare two subjects?
Comparative investigations involve collecting data on different organisms/objects/features, or collecting data under different conditions (e.g., times of year, temperatures, locations) to make a comparison.
What are the 7 steps in scientific investigation?

- Analyze the results and draw a conclusion. ...
- Present the findings.
What is the first step in making a scientific investigation?
The first step in the Scientific Method is to make objective observations . These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
What is scientific hypothesis?
scientific hypothesis, an idea that proposes a tentative explanation about a phenomenon or a narrow set of phenomena observed in the natural world . ... Depending on the results of scientific evaluation, a hypothesis typically is either rejected as false or accepted as true.
What makes research scientific?
Scientific research is the research performed by applying systematic and constructed scientific methods to obtain, analyze, and interpret data . ... Hypothesis should be clear, specific, and directly aim to answer the research question. A strong and testable hypothesis is the fundamental part of the scientific research.
What type of research is an experiment?
Experimental research is a study that strictly adheres to a scientific research design . It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared. Most importantly, experimental research is completed in a controlled environment.
Why is the scientific method important in doing experiments?
It provides an objective, standardized approach to conducting experiments and, in doing so, improves their results. By using a standardized approach in their investigations, scientists can feel confident that they will stick to the facts and limit the influence of personal, preconceived notions.
How do you differentiate the scientific method in philosophy and science?
Philosophy does this by using logical argumentation , while science utilizes empirical data. Philosophy’s explanations are grounded in arguments of principles, while science tries to explain based on experiment results, observable facts, and objective evidence.
What are examples of scientific method?
- Observation: My toaster doesn’t work.
- Question: Is something wrong with my electrical outlet?
- Hypothesis: If something is wrong with the outlet, my coffeemaker also won’t work when plugged into it.
- Experiment: I plug my coffeemaker into the outlet.
- Result: My coffeemaker works!
Is scientific inquiry and scientific method the same?
Scientific inquiry is different from the scientific method. The scientific method follows a linear step-by-step process in order to answer a question, while scientific inquiry does not follow a linear step-by-step process. Scientific inquiry helps you think outside the box to understand the natural world.
What is scientific inquiry?
Scientific inquiry refers to the diverse ways in which scientists study the natural world and propose explanations based on the evidence derived from their work .
What are the 2 types of scientific inquiry?
- The word Science is derived from Latin and means “to know”
- Inquiry is the search for information and explanation.
- There are two main types of scientific inquiry: discovery science and hypothesis-based science.
What is comparative experiment?
