Exploring Science Concepts

What is the scientific method?

• A method used only in chemistry experiments.

• A random guessing technique for solving problems.

• A way to memorize scientific facts without understanding.

• The scientific method is a systematic approach to inquiry that involves observation, hypothesis formulation, experimentation, and conclusion.

Name three states of matter.

• solid, liquid, gas

• mist

• plasma

• vapor

What is the role of a hypothesis in an experiment?

• The hypothesis serves as a summary of the experiment's results.

• The role of a hypothesis in an experiment is to provide a testable prediction that guides the research.

• A hypothesis is an irrelevant statement that does not guide the research.

• A hypothesis is a final conclusion drawn from the experiment.

Define photosynthesis in simple terms.

• Photosynthesis is how plants make their food using sunlight.

• Photosynthesis is the way plants absorb water from the soil.

• Photosynthesis is how animals digest food using sunlight.

• Photosynthesis is the process of plants breathing oxygen.

What are the basic units of life?

• Tissues

• Atoms

• Cells

• Molecules

Explain the difference between a plant cell and an animal cell.

• Plant cells have a nucleus, while animal cells do not.

• Both plant and animal cells contain chloroplasts for photosynthesis.

• The main differences are that plant cells have a cell wall, chloroplasts, and large vacuoles, whereas animal cells have only a cell membrane, no chloroplasts, and smaller vacuoles.

• Animal cells have a cell wall, while plant cells do not.

What is the function of the heart in the human body?

• To produce hormones for growth.

• The function of the heart is to pump blood throughout the body.

• To filter toxins from the blood.

• To digest food in the stomach.

Describe the water cycle.

• The water cycle is the process of water being stored underground.

• The water cycle is a one-time process of water storage.

• The water cycle is the continuous movement of water through evaporation, condensation, precipitation, and collection.

• The water cycle only involves rainfall and rivers.

What is an ecosystem?

• An ecosystem is a community of living organisms and their physical environment interacting as a system.

• A collection of plants in a garden.

• A group of people living in a city.

• A type of weather pattern.

Why is biodiversity important?

• Biodiversity is only important for aesthetic purposes.

• Biodiversity is important for ecosystem health, stability, and human well-being.

• Biodiversity is irrelevant to agricultural productivity.

• Biodiversity has no impact on climate change.
