What a web we weave. Pupils use yarn as the primary resource to create a web depicting the intricacies of a salt marsh ecosystem. They participate in a question and answer session, which leads to an in-depth facilitated discussion about the importance of ecosystems and how daily activities influence the natural order of our environment.

Instructional Ideas

• Allow students to predict the effect of construction or demolition on a food web and describe this as a full class discussion

Classroom Considerations

• Review basic knowledge of predator/prey relationships and food chains prior to beginning this activity

Pros

• Provides students with a great visualization of food webs and how they may be affected
• Household items may be recycled each year
• Easy to attain differentiation and modification

Cons

• None
