Directions:
• To find the equation and power or magnification, use the Microscope Reference photos .
• Answer the questions to the best of your ability within this lab.
• There is a Nutrient Identification Index in the back of this packet, to help determine the deficiencies.
• Complete the various required components of the lab, and reference your google spreadsheet additionally, to note the
recorded pHs, the date they were recorded, and any adjustments or fluctuations that occurred when the data was collected.
• Understanding the relationship between pH and nutrients will help guide your answer to the first Think About It question
section (page 6).
Sample A:
You will need to refer to your data collection sheet.
To calculate the power of magnification, multiply the power of the ocular lens by the power of the objective you are using.
• Write your equation here: ______________________ ________________________
• What is the power of magnification you are using?_______________________
• Describe the nutrient deficiency: What are you seeing on the plant sample? Write using complete sentences.
__________________________________________________________________________________________
__________________________________________________________________________________________
• How does looking at the deficiency compare to the healthier portions of the plant sample? Note differences between healthy
portions and deficient portions of the sample. Write using complete sentences.
