Flux can be view as the rate at which "stuff" passes through a surface. Imagine a next placed in a river and imagine the water that is flowing directly across the net in a unit of time--this is flux (and it would depend on the orientation of the net, the shape of the net, and the speed and direction of the current). It is an important idea throughout physics and is key for understanding Stokes' theorem and the divergence theorem.

Diffusion is the net movement of particles from areas of high concentration (number of particles per unit area) to low concentration. In this activity, students use a molecular dynamics model to view the behavior of diffusion in gases and liquids.

Students examine CERES radiation data to understand how the Earth's tilt causes seasonal differences in incoming solar energy, and to explore how clouds, deserts and ice modulate the reflection of energy from the Sun. The investigation is conducted using the My NASA Data Live Access Server. This resource is part of the poster, Earth's Energy Budget, which describes the role of incoming solar radiation and the gases in the atmosphere and clouds in maintaining the Earth's temperature. The role of atmospheric becomes CO² in climate change and the environments of nearby planets are compared. along with career profiles of energy budget "detectives." A student crossword and matching game test vocabulary understanding.

Focusing on air, water, land and life, this video describes how these components are connected in the Earth system through the flow of energy, cycles of water and biogeochemistry. Methods of studying the Earth system, ranging from field observations to analysis of satellite images are discussed. This video is one of the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.

Students are given an engineering challenge: A nearby hospital has just installed a new magnetic resonance imaging facility that has the capacity to make 3D images of the brain and other body parts by exposing patients to a strong magnetic field. The hospital wishes for its entire staff to have a clear understanding of the risks involved in working near a strong magnetic field and a basic understanding of why those risks occur. Your task is to develop a presentation or pamphlet explaining the risks, the physics behind those risks, and the safety precautions to be taken by all staff members. This 10-lesson/4-activity unit was designed to provide hands-on activities to teach end-of-year electricity and magnetism topics to a first-year accelerated or AP physics class. Students learn about and then apply the following science concepts to solve the challenge: magnetic force, magnetic moments and torque, the Biot-Savart law, Ampere's law and Faraday's law. This module is built around the Legacy Cycle, a format that incorporates findings from educational research on how people best learn.
