Atmospheric Processes: Conduction

Atmospheric Processes: Conduction

Rating

After participating in this activity, students will be able to explain the process of conduction using a molecular model and explain that different materials conduct at different rates. They will also be able to identify air as a poor heat conductor (an insulator). The instructor guide contains detailed background material, learning goals, alignment to national standards, grade level/time, details on materials and preparation, procedure, assessment ideas, and modifications for alternative learners

Atmospheric Processes: Radiation

Atmospheric Processes: Radiation

Rating

In this activity, students investigate how different surfaces absorb heat and apply their experience with the surfaces to interpret real-world situations. From this information, they come to understand that the physical characteristics of a surface have a powerful effect on the way that surface absorbs and releases heat from the sun and that radiation of heat occurs without the involvement of a physical object. The student guide provides an overall description of the activity, a list of materials, the procedure, and observations and questions. The instructor guide contains detailed background material, learning goals, alignment to national standards, grade level/time, details on materials and preparation, procedure, assessment ideas, and modifications for alternative learners.

Body Control Center

Body Control Center

Rating

The amount of monitoring and adjusting that goes on in the human body at any given time is astounding. In this interactive feature every change in activity requires you to make adjustments in respiration or heart rate or energy delivery, and an adjustment to one system often changes the balance in some other system. See if you can do as good a job maintaining the harmony in this virtual body as your nervous system does in you.
