Scientific Method Practice Quiz Questions

1. A _________ group is used as a comparison to the group where things (variables) are changing.

In experimental research, a control group is used as a standard or comparison to the group where variables are being manipulated or changed. The control group is kept unchanged or unaffected by the variables being tested, allowing researchers to compare the effects of those variables on the experimental group. In this context, "Control" and "control" refer to the concept of a control group, while "Controlled" and "controlled" likely refer to the past tense or adjective form of the word, which is not relevant to the question.

3. What do you do to test a hypothesis?

Guess

Collect data

Create an experiment

Publish results

To test a hypothesis, creating an experiment is necessary. This involves designing a controlled procedure to manipulate and measure variables in order to gather data and determine whether the hypothesis is supported or not. By creating an experiment, researchers can systematically investigate the relationship between variables and draw conclusions based on the collected data. Guessing and collecting data are important steps in the scientific process, but they alone cannot effectively test a hypothesis without the implementation of a well-designed experiment. Publishing results comes after the experiment has been conducted and analyzed.

4. Which of these would be called results?

Wondering Why a Fruit Fly was Born

Counting Fruit Flies

Seeing Fruit Flies on an Apple

Number of Fruit Flies

The term "results" refers to a quantitative measure or count of something. In this context, "Number of Fruit Flies" is the only option that presents a numerical value, indicating the count of fruit flies. The other options discuss different aspects related to fruit flies but do not provide a specific count or measurement, making them unrelated to the term "results."

5. The analysis of data gathered during a particular experiment is necessary in order to...

Formulate a hypothesis

Develop a research pan for that experiment

Draw a valid conclusion for that experiment

The analysis of data gathered during a particular experiment is necessary in order to draw a valid conclusion for that experiment. By analyzing the data, researchers can identify patterns, trends, and relationships that exist within the data, allowing them to make informed decisions and draw meaningful conclusions about the experiment. Without analyzing the data, it would be difficult to determine the significance of the results and draw accurate conclusions.

6. Ten bean seedlings in one setup were grown in the dark, while ten seedlings in another setup were grown in sunlight. All other growth conditions were kept the same in both setups. The seedlings grown in the dark were white with long, slender stems. These seedlings soon died. The seedlings grown in the sunlight were green and healthy.Which hypothesis was most likely being tested in this investigation?

Plants grown in the dark cannot perform the process of respiration

Sunlight is necessary for the normal growth of bean plants

Light is necessary for the germination of bean seeds

Light is necessary for proper mineral absorption by plants

The most likely hypothesis being tested in this investigation is that sunlight is necessary for the normal growth of bean plants. This is supported by the observation that the seedlings grown in the dark were white with long, slender stems and soon died, while the seedlings grown in sunlight were green and healthy. This suggests that the absence of sunlight negatively affected the growth and survival of the bean seedlings.
