How to use it
Students are invited to do an experiment which enables them to explore factors that affect photosynthesis. They will measure how other factors can affect photosynthesis. Students are provided with a handout on the procedure for measuring the rate of photosynthesis and on the steps they have to follow in the experiment. The handout contains introductory information and questions teachers can ask before the experiment. Students complete a CER (claim, evidence, reasoning) for their observations showing the relationship between sodium bicarbonate and rate of photosynthesis. Lab report guidelines are included if they want to assign a lab report, but it is not necessary for the activity.
• Possible difficulties for the students
Students who have poor knowledge of English can have problems with understanding the content.
