Forward Plan for Sciences: Planet Earth - Aerobic Respiration

Desired Outcome: I can contribute to the design of an investigation to show the effects of different factors on the rate of aerobic respiration and explain my findings.

Subject: Sciences Level: Fourth Level (Scottish Curriculum)

Topic: Aerobic Respiration

Duration: 4-6 weeks

Week 1: Introduction to Aerobic Respiration - Introduce the concept of aerobic respiration and its importance in living organisms. - Discuss the role of oxygen in aerobic respiration. - Explore the chemical equation for aerobic respiration. - Conduct a class discussion on the factors that may affect the rate of aerobic respiration.

Week 2: Factors Affecting Aerobic Respiration - Investigate the impact of temperature on the rate of aerobic respiration. - Design and conduct an experiment to measure the rate of aerobic respiration at different temperatures. - Collect and analyze data to identify any patterns or trends. - Discuss the findings and draw conclusions about the effect of temperature on aerobic respiration.

Week 3: Factors Affecting Aerobic Respiration (Continued) - Investigate the impact of substrate concentration on the rate of aerobic respiration. - Design and conduct an experiment to measure the rate of aerobic respiration using different substrate concentrations. - Collect and analyze data to identify any patterns or trends. - Discuss the findings and draw conclusions about the effect of substrate concentration on aerobic respiration.

Week 4: Factors Affecting Aerobic Respiration (Continued) - Investigate the impact of pH on the rate of aerobic respiration. - Design and conduct an experiment to measure the rate of aerobic respiration at different pH levels. - Collect and analyze data to identify any patterns or trends. - Discuss the findings and draw conclusions about the effect of pH on aerobic respiration.

Week 5: Factors Affecting Aerobic Respiration (Continued) - Investigate the impact of enzyme concentration on the rate of aerobic respiration. - Design and conduct an experiment to measure the rate of aerobic respiration using different enzyme concentrations. - Collect and analyze data to identify any patterns or trends. - Discuss the findings and draw conclusions about the effect of enzyme concentration on aerobic respiration.

Week 6: Presentation and Reflection - Students present their findings from the investigations conducted. - Reflect on the overall understanding of the factors affecting the rate of aerobic respiration. - Discuss the importance of aerobic respiration in living organisms and its relevance to the environment. - Encourage students to think critically and propose further investigations or research topics related to aerobic respiration.

Assessment: - Ongoing formative assessment through class discussions, group work, and individual participation. - Summative assessment through the presentation of findings and reflections. - Optional written assessment to evaluate students’ understanding of the factors affecting the rate of aerobic respiration.

Resources: - Textbooks, online resources, and scientific journals for background information. - Laboratory equipment and materials for conducting experiments. - Data collection tools such as thermometers, pH meters, and enzyme solutions.

Note: This forward plan is designed to meet the desired outcome of contributing to the design of an investigation to show the effects of different factors on the rate of aerobic respiration. Teachers may modify the plan based on their specific classroom needs and available resources.
