Cloud Catching

Grade Level: 6-8

Introduction: Not surprisingly, scientists who study the cloud forest are interested in the clouds that are constantly covering the landscape.  Yet how can one capture a cloud to learn more about it?  Biologist Greg Goldsmith created a “cloud collector” in an attempt to do just that. Students will examine Goldsmith’s cloud collector to better understand his design and will contemplate the challenges inherent in “catching” a cloud.  Students will then follow the design process to design their own cloud catchers.  Students will also work with peers to discuss strengths and limitations of their designs. 

Objectives: Students will be able to: (1) design a product to address a problem, (2) anticipate and explain limitations of products.

National Science Standards: Design a solution or product (E); evaluate completed technological designs or products (E); communicate the process of technological design (E); understandings about scientific inquiry (A); understandings about science and technology (E); science and technology in society (F); science as a human endeavor (G).
