Lesson notes

Learning Objectives

Indicator: B8.2.1.1.1 - Explain the process of the carbon cycle.

By the end of the lesson, learners can:

Identify the four main processes in the carbon cycle (photosynthesis, respiration, burning, and decay) and describe what happens at each stage.
Draw and label a flow chart that traces the movement of carbon between the atmosphere, plants, animals, and the soil.
Explain, in their own words, how carbon is continuously circulated in nature and give two reasons why the carbon cycle is a repeated pattern.
Use simple diagrams or charts to sequence the stages of the carbon cycle in the correct order.
Communicate their understanding of the carbon cycle clearly to peers, using appropriate scientific terms such as carbon dioxide, glucose, and fossil fuels.

Content standard: B8.2.1.1 - Demonstrate understanding of the process of Carbon cycle as an example of repeated pattern of change in nature and how it relates to the environment
Indicator: B8.2.1.1.1 - Explain the process of the carbon cycle.
Suggested placement: Term 1, Week 5 (Week 5 of the year)
Our suggestion, laid out in curriculum order across three terms of twelve weeks. NaCCA does not fix the week, so follow your school's scheme of learning.

Exemplars (from the NaCCA curriculum)

1. Identify the carbon cycle from the internet, charts or pictures and write short notes on what happens at each stage.
2. Produce a flow chart to trace the process of the carbon cycle in nature.
3. Explain the process of the carbon cycle depicting processes such as
a) Photosynthesis
b) Respiration
c) Burning
d) Decay.
4. Compile information on the carbon cycle and give reasons why it is a repeated pattern e.g. it is because the carbon is circulated continuously in the environment.
