| Lesson Topic: explain that genetic engineering may help to solve the global demand for food by improving the quality and productivity of farmed animals and crop plants, using the examples of GM salmon, herbicide resistance in soybean and insect resistance in cotto |
Learning Objective/s:
- Describe how genetic engineering can increase food production in animals and crops.
- Explain the mechanisms behind GM salmon growth, herbicide‑resistant soybean, and insect‑resistant cotton.
- Evaluate the environmental and socio‑economic implications of GM crops.
- Compare GM technology with conventional breeding and emerging tools such as CRISPR.
|
Materials Needed:
- Projector and screen
- PowerPoint presentation with diagrams
- Printed case‑study handouts (salmon, soybean, cotton)
- Whiteboard and markers
- Exit‑ticket slips
- Short video clip on GM salmon (optional)
|
Introduction:
Start with a quick poll: how many students have heard of genetically modified foods? Connect this to prior learning on DNA and gene expression, then explain that today they will explore how genetic engineering can help meet global food demand. Success criteria: students will describe three GM examples, explain their benefits, and discuss potential risks.
|
Lesson Structure:
- Do‑now (5’) – Students answer the poll question on sticky notes.
- Mini‑lecture (15’) – Overview of global food challenges and introduction to GM technology using slides.
- Guided analysis (20’) – In groups, examine case‑study handouts (salmon, soybean, cotton) and fill a comparison chart.
- Whole‑class discussion (10’) – Groups share findings; teacher highlights key mechanisms and benefits.
- Ethical debate (10’) – Prompt students to consider risks; record arguments on the board.
- Exit ticket (5’) – Write one benefit and one concern for any GM example studied.
|
Conclusion:
Recap that GM organisms can boost productivity but must be evaluated for safety and ethics. Students complete an exit ticket stating one advantage and one remaining question. Homework: read a short article on CRISPR in agriculture and prepare a brief reflection.
