Match the following instruments with their uses in measuring atmospheric conditions.

• Measuring temperature

• Using a barometer

• Measuring humidity

• Using a gas analyzer

• Testing levels of gases

• Using a thermometer

• Measuring atmospheric pressure

• Using a hygrometer

Scarlett and Noah are discussing climate change in their science class. Their teacher asks, "Which of the following is a greenhouse gas?"

• Oxygen

• Nitrogen

• Water Vapor

• Helium

Emily and Aarav are studying the early Earth for their science project. They learned that a certain gas was present in large amounts in the early atmosphere. Which gas was it?

• Oxygen

• Nitrogen

• Carbon dioxide

• Helium

Emily and Mia are learning about the early Earth in their science class. They are curious to know what form of water was present in the early atmosphere. Can you help them find the answer?

• Ice

• Liquid water

• Water vapor

• Snow

During a science fair, Evie asked her team, "Which of the following was NOT a component of the early atmosphere?"

• Water vapor

• Carbon dioxide

• Oxygen

• Ammonia

Match the following environmental changes with their effects on oxygen levels in the atmosphere.

• Reduction in trees leading to lower oxygen production

• Increase in plant life

• Less respiration leading to higher oxygen levels

• Deforestation

• More water covering land reducing plant growth

• Decrease in animal population

• More photosynthesis leading to higher oxygen levels

• Increase in ocean levels

Emily is conducting an experiment in her school lab to understand plant growth. What is required for photosynthesis to occur?

• Light

• Darkness

• Heat

• Cold

Ella is growing plants in her backyard garden to learn about plant growth. Light plays a role in the process of photosynthesis by providing (a)   .

• energy
• carbon
• nitrogen
• oxygen

(a)   is released in respiration along with carbon dioxide and water.

• Oxygen

• Carbon Dioxide

• Water

• Glucose

During a science class experiment, Scarlett observed that the main gas released during respiration is (a)  

• Oxygen

• Carbon Dioxide

• Nitrogen

• Hydrogen
