Photosynthesis Practical, Light Intensity (bubbles vs distance)

These resources were used to guide year 9 pupils through this Key Stage 4 Required Practical.
The experiment does not always work properly (in regards to approximating the intensity of the bubbles produced). Therefore, a sensible results table has been prepared, to share with the students.
Activities for the students were;
-design sensible experiment method
-revise different types of variables

• identify the inverse relationship between Light intensity and distance of lamp from the plant.
• correct the crossed-out data in table
• calculate averages of number of bubbles, use correct units.
• Make graph with correct X axis (light intensity or distance) and Y Axis (dependent, bubbles)
• analyse graph, is there correlation?
• explain graph, what is happening to cause bubbles?
