Lesson 4 - Scientific Inquiry Quiz

A student investigates how different light levels affect aquatic plants. She uses her sense of sight to record how the plants look each day. Based on the process of scientific inquiry explain her process for collecting information.

• She is engaging in scientific inquiry using her judgement based on what she knows about aquatic plants.

• She is engaging in scientific inquiry by recording visual observations of the aquatic plans in different levels of light.

• She is engaging in scientific inquiry by recording data on aquatic plants at light levels based on inferences.

• Since she is not using tolls like microscopes or thermometers, her data cannot be considered scientific.

What is the process called that scientists use to ask questions and investigate the natural world?

• Scientific method

• Natural research

• Hypothesis testing

• Scientific inquiry

A researcher wants to determine if water run off from farm fields sprayed with herbicides affects the hatching success of frog eggs in nearby ponds. What would be the correct order of his scientific approach.

• Hypothesis --> Conclusion --> Data --> Inferences

• Question --> Inferences --> Hypothesis --> Data

• Observation --> Hypothesis --> Inferences --> Conclusion

• Inferences --> Observations --> Conclusion --> Question

Which of the following is NOT a sense used by scientists to collect information about the natural world?

• Touch

• Taste

• Smell

• Intuition

Which of the following is an example of qualitative data?

• The temperature of the ocean is 28°C

• The turtle had a dark brown shell with yellow markings

• The shark traveled eighty six miles west

• The turtle moved 139 kilometers in one day

A datum refers to multiple observations, while datum is a single observation.

• True

• False

Why must scientists clearly record their procedures during an experiment?

• So other scientists can repeat the experiment

• So they can publish a book about it

• To make the experiment easier for beginners

• to keep the experiment secret

Which of the following best explains why scientific inquiry is considered a cyclical process?

• Scientist only follow a fixed sequence of steps

• Observations are always collected in a lab setting

• Each answer often leads to new questions and further investigations

• it ends once the initial question is answered

Students in Mrs. Pollocks Marine Science class wanted to conduct an experiment to see how varying hours of studying would affect test grades on their science midterm. What is the independent variable in this experiment (Lesson 2).

• Test grades

• The science midterm

• The students

• Hours spent studying

What is an inference?

• A direct observation

• A logical explanation based on past knowledge and experience

• A random guess

• A proven fact
