41
A testable prediction made before conducting an experiment is called a
Answer:
Hypothesis
A hypothesis is a tentative statement predicting what might happen in an experiment. It is testable and forms the basis for investigation. If supported by evidence, it can lead to theories or laws.
42
Which of the following is NOT part of the scientific method?
Answer:
Ignoring results
The scientific method values accuracy and evidence, so results must always be considered. Ignoring outcomes undermines reliability. Observing, hypothesizing, and experimenting are essential steps in the process.
43
A well-tested explanation for a wide range of observations is called a
Answer:
Theory
In science, a theory is a comprehensive explanation supported by significant evidence. It explains patterns and predicts outcomes. Unlike a hypothesis, which is a testable guess, a theory has been repeatedly validated.
44
The process of asking questions and testing ideas is known as
Answer:
Scientific method
The scientific method is a structured approach involving observation, hypothesis, experimentation, and conclusion. It ensures reliability and reduces bias in results. Unlike guesswork, it relies on evidence and logical reasoning.
45
The study of living organisms belongs to
Answer:
Biology
Biology is the branch of science devoted to studying living organisms, their structures, processes, and interactions. It covers everything from microscopic cells to entire ecosystems. Unlike geology or astronomy, biology is focused on life.
46
The branch of science that deals with matter and energy is
Answer:
Physics
Physics studies the fundamental principles of matter, energy, motion, and forces. It explains natural laws governing the universe, from tiny particles to cosmic systems. Chemistry and biology focus on matter and life, but physics emphasizes energy and interactions.
47
Who is called the "Father of Modern Science"?
Answer:
Galileo Galilei
Galileo is often regarded as the "Father of Modern Science" for his pioneering work in experimentation, observation, and mathematics. He challenged traditional views and introduced evidence-based methods. His contributions laid the foundation for modern scientific inquiry.
48
The primary aim of science is to
Answer:
Explain natural phenomena
Science focuses on understanding the underlying reasons behind natural events and processes. While technology and inventions may result from science, the main goal is explanation. By explaining phenomena, science provides a foundation for further advancements.
49
The word "science" comes from a Latin term meaning
Answer:
Knowledge
The Latin word _scientia_ means "knowledge." This reflects the core purpose of science: to build knowledge about the natural world. Over centuries, the meaning expanded to systematic and evidence-based learning.
50
Science is best described as
Answer:
Systematic study of the natural world
Science is not just about gathering facts or building tools; it involves a structured process of studying the natural world. It relies on observation, experimentation, and reasoning. This systematic approach helps in understanding patterns, causes, and relationships in nature.
