22
The "Father of Chemistry" is
Answer:
Antoine Lavoisier
Lavoisier revolutionized chemistry with discoveries like the role of oxygen in combustion. He introduced precise measurements and the law of conservation of mass. His work established modern chemistry foundations.
23
Observation means
Answer:
Using senses to gather information
Observations rely on sight, sound, touch, taste, or instruments to collect data. They form the first step of scientific inquiry. Careful observation reduces bias and guides experimentation.
24
A measured quantity always includes
Answer:
A number and a unit
Measurements combine numerical values with units (e.g., 5 meters). Units provide meaning and allow comparison. Without units, numbers alone would lack context.
25
Science benefits society by
Answer:
Solving practical problems
Science provides solutions to challenges in health, technology, environment, and communication. It improves living standards by applying knowledge. Far from limiting progress, it drives innovation.
26
The study of stars, planets, and space is called
Answer:
Astronomy
Astronomy examines celestial objects and cosmic phenomena. It uses observation, physics, and mathematics to understand the universe. Unlike meteorology, it focuses on space beyond Earth.
27
Scientific knowledge is considered dependable because it is
Answer:
Based on observation and experimentation
Science relies on evidence gathered through observation and controlled experiments. This systematic approach separates it from beliefs or hearsay. Reproducibility adds further credibility.
28
Repeating experiments is important to
Answer:
Confirm results
Repetition ensures reliability and consistency of findings. If results are reproducible, they are considered scientifically valid. This practice reduces errors and strengthens conclusions.
29
A scientist who studies plants is known as a
Answer:
Botanist
Botany is the branch of biology that focuses on plants, including their structure, physiology, and ecology. Botanists contribute to agriculture, medicine, and environmental studies.
30
Scientists primarily share findings through
Answer:
