You have just completed thorough observations using various techniques in an effort to determine what is causing the symptoms of the unhealthy plant. Do you have any ideas about what is actually affecting the plant? In this portion of the investigation, you will have the opportunity to experiment to find out.
1. Together as a team, use your data and list 3 different hypotheses regarding what is causing the plants to appear unhealthy. Write on spaces below. Be prepared to discuss your hypotheses in a class discussion.
2. Design an experiment that will test one hypothesis. Write a description of your experimental design and list the materials you will need to perform your experiment. Be prepared to discuss your ideas in a class discussion.
You must get your plan and materials approved by the teacher before you can begin your experiment.
4. Make sure that you write very detailed descriptions of your experiment and devise a data table form to record all your data. You will be writing up this experiment in your lab book and accuracy, detail, and thoroughness will be very important.
