A scientist working in the early 1900s came up with a hypothesis. Over the next
100 years, other scientists tested the hypothesis and found that it could make
predictions about numerous new situations time and time again. This hypothesis can
now rightfully be considered a ________________________
theory

An article that is undergoing ____________________ is
read carefully and checked by other scientists.
Peer review
![Page 12: Point of view that is personal rather than scientific bias.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649d6f5503460f94a50557/html5/thumbnails/12.jpg)
After a scientist publishes a paper, someone else finds evidence that the
paper’s hypothesis may not be correct. The scientist is unhappy, but studies
the new evidence anyway. The scientist is showing which scientific
attitude?
open-mindedness

The process by which organisms keep everything inside their
bodies within certain limits is called
homeostasis.

How does sharing ideas through peer-reviewed articles help
advance science?
Scientists reading the articles may come up with new questions to study.

Using a universal system of measurement is MOST important during which part of scientific methodology?a. asking questionsb. forming a hypothesisc. collecting datad. drawing conclusions
collecting data

A well-tested explanation that explains a lot of
observations is
a theory.

During a controlled experiment, a scientist isolates and tests
a single variable
![Page 21: Point of view that is personal rather than scientific bias.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649d6f5503460f94a50557/html5/thumbnails/21.jpg)
The work of scientists usually begins with
careful observations
![Page 22: Point of view that is personal rather than scientific bias.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649d6f5503460f94a50557/html5/thumbnails/22.jpg)
The basic unit of length in the metric system is the
meter

What are four scientific attitudes that help scientists generate new
ideas?
curiosity, skepticism, open-mindedness, and creativity
![Page 24: Point of view that is personal rather than scientific bias.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649d6f5503460f94a50557/html5/thumbnails/24.jpg)
What is a bias?A bias is a particular preference or point of view that is personal
rather than scientific.
![Page 25: Point of view that is personal rather than scientific bias.](https://reader036.fdocuments.in/reader036/viewer/2022062313/56649d6f5503460f94a50557/html5/thumbnails/25.jpg)
Can a theory change over time? Explain your answer.
A theory can change over time. No theory is considered absolute truth. As new evidence is
uncovered, a theory may be revised or replaced by a more useful explanation.

How does peer review improve the overall quality of a scientist’s
work?
When scientists have articles peer-reviewed, they will find out if there are any mistakes or oversights in their work. They can then fix these mistakes. Peer review also keeps scientists honest. Scientists cannot pass off false data or
make inaccurate conclusions because they know their work will be reviewed by experts.
