Nature of Science Review

Zoe, Lily, and Avery are working on a school project about scientific research. They are discussing the scientific method. What is the scientific method according to their discussion?

• A method used by Zoe, Lily, and Avery to prove their theories

• A step-by-step process used by Zoe, Lily, and Avery to solve problems

• A technique used by Zoe, Lily, and Avery to collect data

• A systematic approach used by Zoe, Lily, and Avery to investigate natural phenomena, make observations, form hypotheses, conduct experiments, analyze data, and draw conclusions.

Michael is conducting a science experiment for his school project. He comes up with a statement that he believes will predict the outcome of his experiment. What is this statement called?

• A hypothesis is a proven fact that does not require any testing.

• A hypothesis is a conclusion drawn from personal opinion rather than scientific investigation.

• A hypothesis is a random guess with no basis in evidence.

• A hypothesis is a proposed explanation or prediction that can be tested through experimentation or observation.

Evelyn, Noah, and Benjamin are working on a science project. They are confused about the steps involved in experimental design. Can you help them understand the correct sequence?

• Identify the problem or question, Formulate a hypothesis, Design the experiment, Collect and analyze data, Draw conclusions, Communicate the results.

• Formulate multiple problems or questions, Design multiple experiments simultaneously, Mix up the data, Draw contradictory conclusions, Confuse everyone with the results.

• Identify the problem or question, Formulate a hypothesis, Conduct the experiment, Ignore the data, Make assumptions, Keep the results to yourself.

• Skip the problem or question, Guess the answer, Collect random data, Draw conclusions based on personal bias, Share the results with no context.

Samuel, Abigail, and Emma are conducting a scientific experiment for their school project. In this context, what does data analysis mean?

• The process of inspecting, cleaning, transforming, and modeling data to discover useful information, draw conclusions, and support decision-making.

• The process of visualizing data in scientific experiments

• The process of analyzing data from non-scientific experiments

• The process of collecting data for scientific experiments

In a school science fair, Benjamin, Liam, and Ava conducted an experiment and collected a lot of data. Why is it important for them to draw conclusions based on this data?

• Drawing conclusions based on data is not important because it is time-consuming and unnecessary.

• Drawing conclusions based on data is not important because it is subjective and unreliable.

• Drawing conclusions based on data is not important because it does not provide any useful insights.

• Drawing conclusions based on data is important because it allows them to make informed decisions and predictions about their experiment.

Noah, William, and Samuel are working on a science project. They are discussing the key components they need to follow for their project based on the scientific method. What are these key components?

• observation, hypothesis, experimentation, data analysis, conclusion, prediction

• observation, hypothesis, experimentation, data analysis, conclusion

• hypothesis, experimentation, data analysis, conclusion, observation

• observation, experimentation, data analysis, conclusion, hypothesis

Evelyn, Emma, and Sophia are working on a science project. How can they test their hypothesis?

• Through intuition and guesswork.

• Through speculation and assumption.

• Through experimentation and observation.

• Through ignoring evidence and making random conclusions.

Anika, Avery, and Ethan are conducting a research study for their psychology class. They need to choose an appropriate experimental design for their study. What are the different types of experimental designs they can consider?

• Correlational designs

• Pre-experimental designs, True experimental designs, Quasi-experimental designs, Factorial designs, Single-subject designs

• Observational designs

• Descriptive designs

Anika, Kai, and Michael are working on a scientific research project. They are discussing the common data analysis techniques they could use. What are some of the techniques they might consider?

• Descriptive statistics, inferential statistics, regression analysis, hypothesis testing, and data visualization.

• Cluster analysis, t-test, ANOVA

• Qualitative analysis, correlation analysis, time series analysis

• Experimental design, data mining, factor analysis

Olivia, Maya, and Rohan have just completed a scientific study on the effects of climate change on local wildlife. Why is it important for them to communicate the results of their study?

• To hide their findings from the public

• To prevent others from building upon their research

• To limit access to scientific knowledge

• To promote transparency, accountability, and the dissemination of knowledge.
