Scientific knowledge is

Dynamic and subject to change

All scientific discoveries result from following the scientific method.

FALSE

Scientific conclusions reached today through careful study will most certainly stand for all time.

FALSE

Scientists accept the notion of obtaining absolute truth and do not accept uncertainty as a part of nature.

FALSE

Science is unlike any other fields of study in that one can be 100% certain of scientific conclusions

False

Scientists can be absolutely certain that a theory is true if they can collect enough evidence to support it.

False

There are no generally accepted ethical principles in the conduct of science.

False

There is a fixed set of steps that scientists always follow.

False

when people know how scientists go about their work, they are less likely to react thoughtfully and more likely to reject them out of hand or accept them uncritically

False

One safeguard against undetected bias in an area of study is

Have many investigators or groups working on the same project.

A scientist's creative imagination depends in part on

His or her prior knowledge and past experiences

Scientific evidence can be biased in how the data is interpreted.

TRUE

True scientific ventures do not allow social aspects to influence experimentation and analysis of results.

TRUE

If a theory is challenged by new evidence, what would occur?

The theory could be altered

One way of describing scientific theories and scientific laws is that:

Theories explain and laws describe

Science assumes that the universe, as its name implies, is a vast single system in which the basic rules everywhere are the same.

True

Scientists believe that knowledge gained by studying one part of the universe can lead to understanding other parts of the universe.

True

Scientists reject the notion of attaining absolute truth and accept some uncertainty as part of nature.

True

Scientists assume that there is a way to secure absolute truth

True. This is to have some sort of explanation for things that happen.

When faced with a claim that something is true, scientists respond by asking

What evidence supports it?

Which of the following is not an aspect of the nature of Science?

a. The goal of science is to discover the laws of nature B. Science is a blend of logic and imagination c. Scientific knowledge is subject to change d. The world is understandable e. Science is a complex social activity

The most fundamental value of a scientific theory is its ability to

explain and predict

Science is truly objective and does not reflect social values or beliefs

false

Scientists must be unbiased and participate in social and political causes.

false

Scientists who view the exact same evidence should reach identical solutions.

false

you must follow the steps of the scientific method if you want to practice good science.

false

A scientific theory is valid as long as new evidence continues to support it

true

As a social activity, science inevitably reflects social values and viewpoints

true

No matter how well one theory explains one set of observations, it is possible that another theory may fit as well or better, or may fit a still wider range of observations

true

funding agencies have direct influence on the direction the scientific studies take

true

what is the average acceleration of an object whose velocity changes from 18 m/s to 10 m/s in 2.0 seconds?

-4 m/s/s

A vacationing family travels east in their car for 4 hours at an average speed of 50 mph, stops and visits a museum for 4 hours, and then travels west 2 more hours at an average speed of 40 mph. The magnitude of their velocity the whole trip was

12 mph average velocity=displacement/time v=120miles/10hours= 12 mph

What is the average acceleration of an object whose velocity changes from 10 m/s to 18 m/s in 4.0 seconds?`

2 m/s/s

A scientific law is

A statement describing a natural event

A scientific claim is a claim that is capable of

Being proven false

Scientists use their creativity when...

Designing their experiments

Children should start learning about scientific studies and the nature of science as soon as they enter school

True

Creativity is an important ingredient in the scientific process.

True

Which of the following is a scientific claim?

a.The muncie walmart burned down yesterday b. all animals that live in water have gills c. all cows have three legs D. A scientific claim something that has the possibility of being proven false.

A scientific hypothesis can be defined as

an educated guess or explanation

there are many matters that cannot usefully be examined in a scientific way

true. Not everything can be usefully examined scientifically
