Scientific Method Quiz

Emma and Eric are in the park observing the behavior of birds. What is the first step they should take in the scientific method?

• Draw a conclusion

• Form a hypothesis

• Make an observation

• Conduct an experiment

Answer explanation

The first step in the scientific method is to make an observation. This involves noticing and describing phenomena, which leads to questions and further investigation.

Emma and Lincoln are conducting a science project. What is a hypothesis?

• A type of experiment

• A prediction based on observations

• A final conclusion

• A measurement tool

Answer explanation

A hypothesis is a prediction based on observations that can be tested through experiments. It is not a final conclusion, a type of experiment, or a measurement tool.

Emma and Eric are conducting an experiment. Which of the following is true about their experiment?

• They always prove a hypothesis to be correct

• They must be done once to get the right answer

• They test the hypothesis

• They are the last step in the scientific method

Answer explanation

Experiments are designed to test hypotheses, allowing scientists to gather evidence and draw conclusions. They do not prove hypotheses correct, must be repeated for reliability, and are not the final step in the scientific method.

During a science fair project, why is it important for Avery to record the results of her experiment?

• To change her hypothesis

• To share the results with others

• To skip other steps

• To avoid making a conclusion

Answer explanation

Recording results is crucial to share findings with others, allowing for verification and further research. This transparency enhances scientific understanding and collaboration, making 'to share the results with others' the correct choice.

Eric and Emma conducted an experiment in their school lab. The experiment they performed is an example of a:

• Lab experiment

• Field experiment

• Natural experiment

• A strange experiment

Answer explanation

The video experiment is conducted in a controlled environment, typical of a lab experiment. This allows for manipulation of variables and precise measurement, distinguishing it from field or natural experiments.

Eric and Akuach conducted an experiment to observe the effects of sunlight on plant growth. The video information above is an example of a:

• Lab experiment

• Field experiment

• Natural experiment

• A strange experiment

Answer explanation

The video describes a situation where variables are not manipulated by the researcher, making it a natural experiment. This type of experiment observes real-world conditions without intervention, unlike lab or field experiments.

Emma and Eric conducted an experiment in their school lab. The video information above is an example of a:

• Lab experiment

• Field experiment

• Natural experiment

• A strange experiment

Answer explanation

The video describes a field experiment, as it involves observing subjects in their natural environment while manipulating certain variables, distinguishing it from lab or natural experiments.

How do scientists like Ehiemua and Emma share their research? Check all that are true to get the mark for this question

• Journals

• Media

• Conferences

• Singing

• Creating an experiment

Answer explanation

Scientists share their research primarily through journals, media, and conferences. Journals publish detailed studies, media helps reach a broader audience, and conferences allow for direct interaction and discussion among researchers.

Eric and Violet conducted an experiment to test a new plant fertilizer. Making sure their experiment gets the same results over and over is an example of

• boring

• validity

• reliabilitity

• controlled variable

Answer explanation

Reliability refers to the consistency of results in an experiment. If an experiment yields the same results repeatedly, it demonstrates high reliability, making it the correct choice over validity or other options.

Eunice and Eric are conducting an experiment in their science class. What is a good way for them to increase the validity of their experiment?

• Be very careful while you are doing the experiment

• Do the experiment more than once or increase the amount of samples used

• change the question

• Reword the hypothesis

Answer explanation

To increase the validity of an experiment, repeating it or using more samples helps ensure that results are reliable and not due to chance. This approach strengthens the findings compared to just being careful or changing wording.
