This chapter provides teachers with instructions to install a school weather station, and to build simple instruments to monitor weather conditions. Materials need to create a homemade weathervane include a two-liter soft drink bottle, a shallow... (View More) metal pie pan, a plastic drinking straw, and a compass. Building an anemometer requires plastic cups, soda straws, a pencil with an unused new eraser on the end, a paper punch, and a thumbtack. Thermometers and a rain gauge must be purchased. A data table is included for estimating windspeed using the anemometer. The chapter includes research ideas that allow students to validate their instruments and test the predictive capability of resources such as the Farmer's Almanac. This resource is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The resource includes background information, teaching tips and questions to guide student discussion. This is chapter 15 of Meteorology: An Educator's Resource for Inquiry-Based Learning for Grades 5-9. The guide includes a discussion of learning science, the use of inquiry in the classroom, instructions for making simple weather instruments, and more than 20 weather investigations ranging from teacher-centered to guided and open inquiry investigations.

In this activity, students quantitatively evaluate the accuracy of a classification and understand a simple difference/error matrix. Students sort birds into three possible classes based on each bird’s beak: carnivores (meat eaters), herbivores... (View More) (plant eaters), and omnivores (meat and plant eaters). Students compare their answers with a given set of validation data and generate a difference/error matrix. Students discuss how to improve their accuracy based on identifying specific mistakes they made as indicated by the difference/error matrix. The resource includes color diagrams of common birds, a data table, and four student activity sheets. The activity is part of the Land Cover/Biology chapter of the GLOBE Teacher's Guide, and is supported by Land Cover/Biology protocols. GLOBE (Global Learning and Observation to Benefit the Environment) is a worldwide, hands-on, K-12 school-based science education program. (View Less)
