What does a biologist study?

Living things (plants, animals, humans, microorganisms)

100

What does chemistry focus on?

The study of substances, their properties, and how they change (matter, atoms, molecules)

100

What does a physicist study?

Forces, energy, motion, and the fundamental laws of nature

100

What is Earth & Environmental Science about?

The study of Earth’s systems and environment (rocks, weather, ecosystems, pollution)

200

Name one living thing a biologist might observe in nature.

Examples: birds, insects, trees, fish, mammals

200

Name a common chemical change you see at school or home.

Examples: vinegar reacting with baking soda, rust forming on metal, cooking an egg

200

Name one force you feel every day.

Gravity (also acceptable: friction, push, pull)

200

Name something a geologist studies.

Rocks, minerals, volcanoes, Earth’s structure

300

What is the process called when plants make their own food using sunlight?

Photosynthesis

300

What are atoms?

The basic building blocks of all matter; tiny particles that make up elements and substances

300

What causes a ball to fall to the ground when dropped?

Gravity

300

What do we call the layer of air around Earth?

The atmosphere

400

True or false: Bacteria are living things.

True

400

What happens when vinegar is mixed with baking soda?

A chemical reaction occurs producing carbon dioxide gas (bubbles/fizzing)

400

True or false: Sound is a form of energy.

True

400

True or false: Recycling helps protect the environment.

True

500

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.

500

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.

500

Describe how energy is transferred when you kick a soccer ball.

Your foot transfers kinetic energy to the ball, causing it to move.

500

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.
