Many students are squeamish about spiders. But when you spray spider webs with a water mister, they are easy to see and gorgeous, and just about anyone can get caught up in exploring them! After this activity, students will probably notice and appreciate spider webs everywhere, including when they return home. They will also probably be more careful to avoid knocking webs down while walking around. In this activity, students notice spider webs as they walk. When students arrive at an exploration site, pairs search for different kinds of webs in the area, mist them with water, then regroup to discuss their observations and think about how different types of webs help spiders catch different kinds of prey. Students learn about different web types, then return to the field to use a key to identify different kinds of webs. They also make explanations about how the structures of the webs they find function to catch prey.

This activity is designed to be a follow-up to the Spider Exploration activity, and to be done with students who are excited about and interested in spider webs. It’s meant for instructors who want to help their students learn how to conduct a more formal and structured investigation. Students compare quantity of spider webs in two different plant communities. The basic structure of this investigation is pre-planned, but students discuss and plan how to make it a fair test with the least amount of bias as possible. Students also analyze their data, make explanations from their findings, discuss possible inaccuracies of their results, and reflect on science practices and investigation design.
