Calculating the necessary energy to recycle aluminum from aluminum oxide which was a question on the 2015 AP Chemistry exam. [6:16]

Khan Academy learning modules include a Community space where users can ask questions and seek help from community members. Educators should consult with their Technology administrators to determine the use of Khan Academy learning modules in their classroom. Please review materials from external sites before sharing with students.

In this video adapted from Alaska Sea Grant, discover why multiple tsunamis resulted from the Great Alaska Earthquake of 1964.

This simple demonstration helps students understand the concept of conduction. Site includes background information, images, and lesson plans outlining the demonstration of conduction.

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Discuss the importance of electrons in the transfer of energy in living systems
Explain how ATP is used by cells as an energy source

By the end of this section, you will be able to do the following:

Explain metabolic pathways and describe the two major types
Discuss how chemical reactions play a role in energy transfer

In the following video, Paul Andersen explains how energy can neither be created nor destroyed but may be transferred. Energy comes in many forms. [4:09]

In the following video Paul Andersen explains how energy can be transferred from warmer objects to colder objects through heat. Temperature is a measure of the average kinetic energy of the particles in a substance. When two objects are in contact collisions between the particles will transfer energy from the warmer object in the form of heat. [5:05]

In the following video Paul Andersen explains how heating is the transfer of energy (heat) from a warmer object to a cooler object. Heat can be transferred through conduction, convection and radiation. At the microscopic level conduction results from the collision of particles and therefore the transfer of kinetic energy. [3:32]

An example of how ice can cause energy to transfer and reduce the temperature of water. [11:23]

This article continues an examination of each of the seven essential principles of climate literacy on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 2 covers the complex interactions among the components of the Earth system. The author discusses the scientific concepts underlying the interactions and expands the discussion with diagrams, photos, and online resources.

This video segment adapted from the Atmospheric Radiation Program explains the differences in the formation of tropical convective cloud systems over islands and over the ocean.

The author explains heat transfer and how it applies to living in extremely cold environments.

Slideshow that looks at energy flow in an ecosystem. Explains what an ecosystem is, how energy flows through it, the producers and consumers of energy, and food chains. Links to a video about plastic debris in the ocean.

In this video produced by ThinkTV, explore the effects of land masses on local climate conditions, and learn about regional impacts of land-atmosphere interactions.

This unit provides the framework for conducting an “engineering design field day” that combines 6 hands-on engineering activities into a culminating school (or multi-school) competition. The activities are a mix of design and problem-solving projects inspired by real-world engineering challenges: kite making, sail cars, tall towers, strong towers and a ball and tools obstacle course. The assortment of events engage children who have varied interests and cover a range of disciplines such as aerospace, mechanical and civil engineering. An optional math test—for each of grades 1-6—is provided as an alternative activity to incorporate into the field day event. Of course, the 6 activities in this unit also are suitable to conduct as standalone activities that are unaffiliated with a big event.

Students learn to apply the principles and concepts associated with energy and the transfer of energy in an engineering context by designing and making musical instruments. They choose from a variety of provided supplies to make instruments capable of producing three different tones. After completing their designs, students explain the energy transfer mechanism in detail and describe how they could make their instruments better.
