31
Which statement about science is accurate?
Answer:
It is constantly changing
Science evolves as new discoveries and evidence emerge. Unlike rigid belief systems, it adapts to updated knowledge. This openness ensures growth and accuracy over time.
32
The study of Earth’s structure and processes is called
Answer:
Geology
Geology investigates the Earth’s crust, rocks, and processes like earthquakes and volcanoes. It provides insight into Earth’s history and resources. Unlike astronomy, it focuses specifically on our planet.
33
Biology includes the study of
Answer:
Living things
Biology explores organisms, from microbes to humans, and their ecosystems. It examines structures, functions, growth, and evolution. Unlike geology or astronomy, its focus is life.
34
Chemistry mainly focuses on
Answer:
Atoms and molecules
Chemistry studies the composition, structure, and interactions of matter at the atomic and molecular level. While energy and matter overlap with physics, chemistry zooms into atomic interactions.
35
Who made major contributions during the Scientific Revolution?
Answer:
Isaac Newton
Isaac Newton’s laws of motion and gravitation revolutionized science. His work unified celestial and terrestrial physics. Unlike philosophers or artists, Newton’s work reshaped modern scientific thinking.
36
The application of scientific knowledge for practical use is called
Answer:
Technology
Technology applies scientific discoveries to create tools, devices, and systems. It bridges the gap between theory and practice. While engineering uses technology, the broader concept is technology itself.
37
A scientific law
Answer:
Describes a pattern in nature
Scientific laws summarize consistent natural patterns, often expressed mathematically. Unlike theories, laws do not explain why phenomena occur but state what happens. They are based on repeated observations.
38
In an experiment, the factor deliberately changed by the scientist is the
Answer:
Independent variable
The independent variable is manipulated to test its effect on the dependent variable. Controlled variables remain unchanged to ensure fairness. This distinction helps identify cause-and-effect relationships.
39
Data refers to
Answer:
Information collected during an experiment
Data includes recorded observations, measurements, or facts gathered through experiments. It forms the foundation for analysis and conclusions. Unlike opinions or guesses, data is evidence-based.
40
Controlled experiments are designed to test
Answer:
Only one variable at a time
A controlled experiment isolates a single independent variable to determine its effect. All other factors are kept constant. This ensures reliable results and reduces confusion caused by multiple influences.
