Basic 8 Science Term 1 Week 4 Lesson Plan

Revise with learners on the previous lesson.

Concrete-resource task: Set out these resources for each group: Potted maize plant; Charcoal pieces; Printed carbon-cycle diagram. Learners observe and safely handle the specimens or apparatus, using them in the investigation or model below. Brainstorm learners to name different forms of carbon that they have encountered. Revise with learners to define key terms such as photosynthesis and respiration. Have learners discuss the role of carbon dioxide in the atmosphere.

Use peer discussion and effective questioning to find out from learners what they have learnt during the lesson.

Share learning indicators and introduce the lesson.

Concrete-resource task: Set out these resources for each group: Potted maize plant; Charcoal pieces; Printed carbon-cycle diagram. Learners observe and safely handle the specimens or apparatus, using them in the investigation or model below. Guide learners to explain the carbon cycle. The carbon cycle is the biological cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, and atmosphere of earth. Let learners identify the carbon cycle from charts or pictures and write short notes on what happens at each stage. Stage 1: Carbon enters the atmosphere as CO2. Stage 2: CO2 is absorbed by autotrophs such as green plants. Stage 3: Animals consume plants, thereby, incorporating carbon into their system. Stage 4: Animals and Plants die, their bodies decompose and carbon is reabsorbed back into the atmosphere.

Take feedback from learners and summarize the lesson.

Concrete-resource task: Set out these resources for each group: Potted maize plant; Charcoal pieces; Printed carbon-cycle diagram. Learners observe and safely handle the specimens or apparatus, using them in the investigation or model below. Explain the process of the carbon cycle depicting processes such as a) Photosynthesis b) Respiration c) Burning d) Decay Have learners 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 let learners identify the carbon cycle from charts or pictures and write short notes on what happens at each stage. Stage 1: Carbon enters the atmosphere as CO2. Stage 2: CO2 is absorbed by autotrophs such as green plants. stage 3: Animals consume plants, thereby, incorporating carbon into their system.
