Nutrient Presentation
It will be your job to teach the class about your assigned nutrient. Research the nutrient and
create a PowerPoint or Prezi with the following information:
• Title page
o Nutrient name
o Nutrient chemical abbreviation
o Group member names
• Subsequent pages that cover:
o Effect on plant growth
o Deficiency symptoms
o 2 pictures showing plants with the deficiency
o Toxicity symptoms (if applicable)
o Sources (APA or MLA format)
Your presentation will not be graded on length. It will be graded on:
• Completeness and accuracy of information
• Appearance of slides
• Presentation style
• Proper citations
During your classmates’ presentations, use the chart on the following pages to record the
required information.
