Question 1

Question

Question 3

A) Which statement about the purpose of the field of science is false? (1 point)

Science works to establish a collection of unchanging truths.

Useful predictions come from derived explanations of science.

Events of the natural world can be explained by science.

Science is used to investigate the natural world.

Question 4

A) Which statement represents a value judgement in science? (1 point)

Question 5

A) What does it mean for a hypothesis to have explanatory power? (1 point)

The hypothesis has no evidence to support it.

The hypothesis is testable.

The hypothesis has been tested many times and over a wide variety of conditions. The hypothesis has an independent and a dependent variable.

Question 6

A) Which of the following describes a hypothesis? (1 point)

It is based on beliefs or opinions.

Acceptance is guaranteed by the community.

It is testable through experimentation.

One trial is enough to show its validity.

Question 7

A) Why do scientists generate a hypothesis before conducting research? (1 point)

It provides a framework by which the collected data can be interpreted.

It helps decide which data should be ignored in their results.

It helps shape the parameters of the study by predicting a result.

It provides a result prior to experimentation around which the study can be performed. Question 8

A) What is the best way to refute a hypothesis? (1 point)

Ignore negative results that are obtained from experimentation.

Continually test and observe the phenomenon.

Prevent extensive experimentation that collects valid data.

Use only widely accepted theories as the foundations of them.

Question 9

A) Which describes a scientific theory? (1 point)

It is a statement that is always true.

It is an idea that can be revised or replaced.

It is the opening statement of an experiment.

It is the problem to be solved through experimentation.

Question 10

A) Which provides the basis for all scientific theories? (1 point)

They are general assumptions that show how systems function. They revolve around mathematical principles that can be proven true. They use large amounts of data collected over time.

They need to include observations from a single discipline.

Question 11

A) Why is it important for a scientific theory to be supported by multiple pieces of evidence? (1 point)

To increase the likelihood that it is accurate and reflects reality.

To ensure that it can be taught in schools

To make it simpler to understand and communicate the findings.

To prevent future experiments from discrediting it.

Question 12

A) What does a scientific theory have that a hypothesis does not? (1 point)

Reliable methods of experimentation

Predicted outcomes of future experiments

Limited support across multiple disciplines

Large amounts of evidence to support it

Question 13

A) Which statement describes a scientific theory compared to a scientific hypothesis? (1 point)

A hypothesis is an initial explanation while a theory is well-supported.

A hypothesis involves calculations, but a theory does not.

A theory is less specific than a hypothesis.

A theory is a guess while a hypothesis is a fact.

Question 14

A)

A scientist makes the following prediction:

This chemical will lower freezing points of certain liquids.

Extensive testing on various liquids supports the prediction. Over many years, multiple scientists repeat the experiment and get the same results. How has the categorization of this prediction changed?

(1 point)

The theory has become a prediction.

The theory has become a hypothesis.

The hypothesis has become a theory.

The prediction has become a hypothesis.
