Biology
What does a biologist study?
Living things (plants, animals, humans, microorganisms)
What does chemistry focus on?
The study of substances, their properties, and how they change (matter, atoms, molecules)
What does a physicist study?
Forces, energy, motion, and the fundamental laws of nature
What is Earth & Environmental Science about?
The study of Earth’s systems and environment (rocks, weather, ecosystems, pollution)
Name one living thing a biologist might observe in nature.
Examples: birds, insects, trees, fish, mammals
Name a common chemical change you see at school or home.
Examples: vinegar reacting with baking soda, rust forming on metal, cooking an egg
Name one force you feel every day.
Gravity (also acceptable: friction, push, pull)
Name something a geologist studies.
Rocks, minerals, volcanoes, Earth’s structure
What is the process called when plants make their own food using sunlight?
Photosynthesis
What are atoms?
The basic building blocks of all matter; tiny particles that make up elements and substances
What causes a ball to fall to the ground when dropped?
Gravity
What do we call the layer of air around Earth?
The atmosphere
True or false: Bacteria are living things.
True
What happens when vinegar is mixed with baking soda?
A chemical reaction occurs producing carbon dioxide gas (bubbles/fizzing)
True or false: Sound is a form of energy.
True
True or false: Recycling helps protect the environment.
True
Explain how humans and plants are connected in the oxygen and carbon dioxide cycle.
Humans breathe in oxygen and breathe out carbon dioxide, while plants take in carbon dioxide and release oxygen during photosynthesis, creating a cycle that supports life.
Explain why water can dissolve sugar but not oil.
Sugar is water-soluble because it is polar like water; oil is non-polar so it does not dissolve in water.
Describe how energy is transferred when you kick a soccer ball.
Your foot transfers kinetic energy to the ball, causing it to move.
Give one way humans can reduce pollution and explain how it helps the Earth.
Examples: Recycling reduces waste in landfills, planting trees helps absorb carbon dioxide, using public transport reduces air pollution.
