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.
