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.

The heart-breaking addendum to the Chernoybl accident is that thousands of children were and are still affected by the fallout. Here are the results of an international organization that strives to help these children.

An illustrated tutorial describing the structure and function of the chloroplast organelle in a plant cell. [0:37]

Students focus on the three interconnected choices global society faces as Earth's climate continues to change -- suffer, adapt, and mitigate -- to analyze and predict current and future impacts to Earth's systems. Using videos excerpted from NOVA: Decoding the Weather Machine, students explore ways that adaptation and mitigation strategies can work at various levels to minimize suffering and then develop an evidence-based action plan for their local community

This site provides a complete biography of Christian Doppler (1803-1853 CE), founder of the Doppler principle of sound waves. Includes quotes from Doppler and those who knew him, as well as an outline of his scientific achievements.

In UCM, the net force called Fc is equal to mv2/r and is directed toward the center. This is demonstrated by an object that is suspended by a string and is moving in a circular path which makes a conical pendulum. In this experiment, you will measure the tension and the length of the string to show that net force Fc = mv2/r.

From The Physics Classroom. Uses easy- to-understand language to discuss how circular motion principles apply to the motion of satellites. Describes the tangential velocity and centripetal acceleration of a satellite. Includes many diagrams and a Check Your Understanding section.

This site features a circulatory system internet workshop focused on diseases and healthy living. Students and teachers will benefit from the resources linked to this site.

Sal Khan introduces the circulatory system function and the structure and function of the heart. [14:53]

College-level online course highlighting the fundamentals of ecology. Course topics include coevolution of the biosphere, geosphere, atmosphere, and hydrosphere; photosynthesis and respiration; and the carbon, nitrogen, and water cycles. Other topics include energy flow through the biosphere and changes in ecosystems. This course features selected lecture notes, assignments with solutions, projects and examples, and exams with solutions.

In the animal kingdom, there are seven living classes in the phylum Vertebrata. The Palomar College shares detailed information on each of these classes. Includes examples and photos as well as a follow-up quiz.

This lesson will introduce the systematic classification of matter used in chemistry, defining the terms heterogeneous, homogeneous, pure substance, mixture, compound, element and providing examples.

This video [0:25] adapted from KTOO takes a look at Earth's warming and cooling cycles and the current atypical trend of warming that is impacting the glaciers in Alaska's Inside Passage.

This resource provides solutions to global warming issues and problems, with specific information pertaining to the Pacific Northwest.

Read what a cloud is and how to identify three different types. Includes audio narration in English and Turkish with text in English.

This interactive resource adapted from the National Park Service describes the different kinds of sediments that make up coastlines, with a focus on the variety in color, size, and sorting.

This interactive resource adapted from the National Park Service describes the many forces that affect shorelines, including tides, weathering, erosion, and deposition. Includes background reading handout and discussion questions.

Students will learn the basic constructs of a video game using the Scratch interface. Students use Scratch to learn about algorithms and event-driven programming. Object-oriented concepts are introduced through the use of sprites and the stage. Students use critical thinking and creativity to complete and enhance Hungry Mouse, a game that they develop using Scratch.

Estimated time required: 2 class periods.

Technology required for this lesson: Design Software, Laptop/Desktop.
