Begin with a discussion on how plants and animals obtain their food and energy. Highlight the differences in their methods and introduce the concept of cellular respiration as a key process in energy production.

Engage students with a thought-provoking question: How do cells use the food we eat to give us energy?

Explain the process of cellular respiration, emphasizing its role in providing energy to cells. Discuss how it occurs in the mitochondria and involves oxygen and glucose.

Use the 'Cellular Respiration' video to visually demonstrate how glucose and oxygen interact to produce energy, carbon dioxide, and water. This video provides a tangible example of cellular respiration in action.

Facilitate a discussion on the waste products of cellular respiration and how plants and animals manage them. Encourage students to think about the cycle of energy and matter in ecosystems.

Watch the 'Characteristics of Organisms' video to explore how different organisms meet their survival needs and how cellular respiration fits into their life processes.

Conduct a simple experiment to observe cellular respiration in action using yeast, sugar, and balloons. This activity helps students visualize the production of carbon dioxide as a byproduct.

Assign the 'Cellular Respiration' assessment to reinforce students' understanding of how glucose and oxygen are used to produce energy and waste products.

Use formative assessment techniques such as exit tickets or quick quizzes to gauge students' grasp of cellular respiration and its importance in energy production.

Have students reflect on what they learned about cellular respiration and its role in both plant and animal cells. Encourage them to write a short paragraph summarizing their understanding.

Administer the 'Review – Life on Earth' assessment to evaluate students' comprehension of cellular respiration and related life science concepts.

Encourage students to explore further by researching how cellular respiration varies among different organisms and environments.
