Worksheet: Branches of Science – Science 7 Practice
We are given three branches of science:
-
Physical Science
-
Life Science
-
Earth Science
And we need to match each description and set of images to the correct branch.
---
Step-by-step Analysis:
####
Row 1:
Images:
- Beakers with colored liquids (chemistry lab)
- Atomic model (atom with nucleus and electrons)
- Newton’s cradle (demonstrates energy transfer)
- Magnetic field lines around a bar magnet
Description: *"the study of energy and matter."*
➡️ This clearly refers to
Physical Science, which includes physics and chemistry — both dealing with energy, matter, forces, and atomic structure.
✔ Answer: Physical Science
---
####
Row 2:
Images:
- A beetle (an insect)
- DNA double helix
Description: *"the study of living things."*
➡️ This is about organisms and genetics — topics in
Life Science, which includes biology, zoology, botany, etc.
✔ Answer: Life Science
---
####
Row 3:
Images:
- A landscape (like Grand Canyon)
- Earth from space
Description: *"the study of Earth and other objects in space."*
➡️ This involves geology, meteorology, astronomy, and planetary science — all part of
Earth Science.
✔ Answer: Earth Science
---
✔ Final Answer Table:
|
Branch |
Images & Description |
|---------------------|--------------------------|
|
Physical Science | The study of energy and matter. (Lab beakers, atom, Newton's cradle, magnet) |
|
Life Science | The study of living things. (Beetle, DNA) |
|
Earth Science | The study of Earth and other objects in space. (Landscape, Earth from space) |

🔍 Explanation Summary:
-
Physical Science: Studies non-living systems like atoms, energy, motion, and chemical reactions.
-
Life Science: Focuses on living organisms — their structure, function, growth, evolution, and interactions.
-
Earth Science: Deals with Earth’s systems, including geology, weather, climate, and space objects.
Each row matches the definition and images correctly.
✔ All answers are now filled and explained!
