Understanding the Carbon Cycle

Miss Katherine introduces lesson 3.2 on matter and energy in ecosystems, focusing on a game involving carbon tracking. Students are encouraged to use paper and tokens to create a game board. The lesson revisits an investigation question about carbon changes in closed ecosystems, comparing the carbon cycle to the water cycle. The video emphasizes that Earth is a closed system, and human activities like burning fossil fuels impact the carbon cycle. Students are prompted to reflect on the investigation question regarding carbon distribution in ecosystems.

What additional materials are suggested for today's lesson?

• A textbook and a notebook

• A calculator and a ruler

• A computer with internet access

• A large sheet of paper and 30 small tokens

What can be used as game tokens in the activity?

• Only dice

• Only strips of paper

• Any small objects like dice or Monopoly houses

• Only Monopoly houses

What is not needed for today's lesson according to the teacher?

• A calculator

• Game tokens

• Access to Amplify online

• A large sheet of paper

What is the main focus of today's investigation question?

• How plants produce oxygen

• How water cycles in an ecosystem

• How carbon changes in a closed ecosystem

• How energy is transferred in food chains

How is the carbon cycle similar to the water cycle?

• Both involve the movement of gases only

• Both involve the movement and cycling of elements

• Both are unaffected by human activities

• Both occur only in the atmosphere

What human activity is mentioned as altering the carbon cycle?

• Using solar panels

• Recycling waste

• Burning fossil fuels

• Planting trees

Why is Earth considered a closed system?

• Because matter does not leave or enter from space

• Because it has no atmosphere

• Because it is the only planet with life

• Because it is flat

What happens to carbon if it increases in one part of a closed system?

• It turns into water

• It disappears

• It decreases somewhere else

• It remains unchanged

What is the purpose of the warm-up thinking question?

• To calculate energy transfer rates

• To memorize the periodic table

• To reflect on the carbon distribution in ecosystems

• To test knowledge on water cycles

What is the main theme of the lesson?

• The nitrogen cycle

• Photosynthesis

• The carbon cycle in ecosystems

• The water cycle
