Program Overview
The Great Explorations in Math and Science (GEMS) series includes more than 50 teacher's guides and handbooks for preschool through grade 10. About 35 of these are appropriate for middle school. The series also includes several assembly presenter's guides and exhibit guides. New guides and handbooks continue to be developed, and current titles are revised frequently. The series is designed to teach key science and mathematics concepts through activity-based learning. The time needed to complete GEMS units varies from about 2 to 10 class sessions.
Teacher's Guide
Recommended grade level:
6-8+.
Students explore the physical phenomenon of convection and generalize their findings to understand wind patterns in Convection: A Current Event. The teacher's guide introduces the concept of convection and then offers 3 sessions: "Observing Convection in Water," "Getting the Whole Picture," and "Convection and Wind." In the first session, students use food coloring to trace convection currents in water. In the second session, they apply their knowledge to guide an imaginary submarine through ocean currents generated near a hot volcanic vent. In the third session, the teacher presents 3 demonstrations to show that convection occurs in gases as well as in liquids, and students apply what they have learned to predict air flow in a room and wind patterns.
Each session in Convection: A Current Event requires 30 to 60 minutes and includes a materials list, preparation steps, and directions for activities and discussion. The guide also includes background information, summary outlines for each lesson, and reproducible data sheets.
