Carbon Cycle and Biodome Concepts

Miss Catherine introduces lesson 3.1, focusing on carbon in ecosystems. Students are tasked with understanding carbon's role in a biodome, particularly its decrease due to decomposer population changes. The lesson covers photosynthesis and cellular respiration, emphasizing carbon's importance in these processes. Students are encouraged to reflect on carbon's movement and its implications for biodome design.

What materials are suggested for students to have during the lesson?

• A calculator and ruler

• A pen or pencil and paper

• A textbook and highlighter

• A laptop and headphones

What is the main question posed by Dr. Brian Worry in his email?

• How to increase plant growth in the biodome?

• What happened to the carbon that used to be in the air of the biodome?

• Why did the decomposer population increase?

• How to improve the water cycle in the biodome?

Which process involves plants taking in carbon dioxide from the air?

• Fermentation

• Photosynthesis

• Decomposition

• Cellular respiration

What do plants produce during photosynthesis that is crucial for energy storage?

• Nitrogen compounds

• Energy storage molecules

• Oxygen molecules

• Water molecules

In cellular respiration, what is released back into the air?

• Hydrogen

• Carbon dioxide

• Oxygen

• Nitrogen

What was the effect of the decrease in decomposer population in the biodome?

• Increase in animal population

• Decrease in carbon dioxide in the air

• Decrease in water levels

• Increase in plant growth

Why is it important for the Eco nots to track carbon in their new biodome?

• To understand why the previous biodome collapsed

• To prevent plant overgrowth

• To reduce water usage

• To increase oxygen levels

What is the main focus of the last chapter of the unit?

• The role of sunlight in plant growth

• The water cycle in ecosystems

• The fate of carbon in the biodome

• The impact of human activities on ecosystems

What is the mystery that students are asked to reflect on?

• The increase in plant species

• The missing carbon in the biodome

• The rise in animal population

• The change in water levels

What should students do after reflecting on the missing carbon?

• Create a presentation

• Discuss with a partner

• Pause the video and answer a question

• Write a report
