Goldenrod and Horsetail in their Natural Habitats

This shows different species of plants that grow in Iowa ditches, forestry areas, and places that aren’t typically disturbed by humans. Students will make comparisons of horsetail and goldenrod in different habitats. 

• Why do these two plants tend to flourish in roadside ditches more than other plants?

• As you looked at the pictures, what similarities and differences did you notice between the two plants?
• Do these two plants serve the same purpose?

Students could:

• Compare and contrast different plant features and habitats. 
• Research to learn differences between horsetail and goldenrod. They can consider 
  • Why horsetail is hollow inside? 
  • Are any of the plants invasive (meaning they spread very easily and can take over areas)?
  • Why does goldenrod have blooms/flowers and horsetail doesn’t?
  • How do the plants spread?
• Determine if these plants grow in the same habitats or different in Iowa? Nationally? Worldwide?
• Compare these plants with other plants in the area.
