Students will use this model to experiment how changing the condition for photosynthesis affects the photosynthetic products.
Duration 50 Minutes |
Setting Laboratory or Classroom |
Grouping 2 students |
PTI Inquiry 1.1, 1.3, 2.1, 3.1, 3.2, 3.3, 3.7, 4.3, 5.2, 5.3, 5.9, 7.1, 7.2 |
Lesson Components | Time | Inquiry Skills | Tech. Used | Engage Level | Brief Description |
---|---|---|---|---|---|
Engage | 5 min | 1.1, 1.3, 2.1 | Blackboard, overhead, etc. | 2 | As a class, draw out a visual model of the photosynthetic process on the blackboard, etc. A series of probing questions (Appendix A) can be asked to the class to make sure that all relevant factors are included. |
Explore | 20 min | 2.1, 3.1, 3.2, 3.3, 3.7, 4.3 | Lab equipment specified in materials | 3 | Students will design an experiment to measure oxygen production from photosynthesis. Students will measure how much oxygen has been produced by the lab set up (high light vs. low/no light) over the specified time frame. Data will be collected, plotted on a graph, and compared among the class. |
Explain | 5 min | 4.3, 5.2, 5.3, 7.1, 7.2 | none | 3 | Students will work in pairs and answer a series of questions explaining what occurred during the experiment. (What gas was increasing, what was decreasing, etc?) |
Expand | 10 min | 5.9 | none | 2 | Students discuss what they think would happen in situations where other photosynthetic variables changed like temperature, carbon dioxide availability, etc.) |
Evaluate | 10 min | none | 1 |
Level of Student Engagement | ||||
---|---|---|---|---|
1 | Low | Listen to lecture, observe the teacher, individual reading, teacher demonstration, teacher-centered instruction | ||
2 | Medium | Raise questions, lecture with discussion, record data, make predictions, technology interaction with assistance | ||
3 | High | Hands-on activity or inquiry; critique others, draw conclusions, make connections, problem-solve, student-centered |
Please share your comments (e.g., strengths, areas for improvement, your implementation results if you taught the lesson in your class, and any modifications you made). Thanks!
