Artists are often particularly keen observers and precise recorders of the physical conditions of the natural world. As a result, paintings can be good resources for learning about ecology. Teachers can use this lesson to examine with students the interrelationship of geography, natural resources, and climate and their effects on daily life. It also addresses the roles students can take in caring for the environment. Students will look at paintings that represent cool temperate, warm temperate, and tropical climates.
In this lesson students will: Identify natural resources found in particular geographic areas; Discuss ways in which climate, natural resources, and geography affect daily life; Apply critical-thinking skills to consider the various choices artists have made in their representations of the natural world; Make personal connections to the theme by discussing ways they can be environmental stewards; Identify natural resources found in particular geographic areas; Discuss ways in which climate, natural resources, and geography affect daily life; Apply critical-thinking skills to consider the various choices artists have made in their representations of the natural world; Make personal connections to the theme by discussing ways they can be environmental stewards.
Modern China presents a dual image: a society transforming itself through economic development and social revolution; and the world’s largest and oldest bureaucratic state, coping with longstanding problems of economic and political management. Both images bear the indelible imprint of China’s historical experience, of its patterns of philosophy and religion, and of its social and political thought.
In this free Chinese studies online course, these themes are discussed to understand China in the modern world and as a great world civilization that developed along lines different from those of the Mediterranean.
This interactive activity for grades 8-12 features eight models that explore atomic arrangements for gases, solids, and liquids. Highlight an atom and view its trajectory to see how the motion differs in each of the three primary phases. As the lesson progresses, students observe and manipulate differences in attractions among atoms in each state and experiment with adding energy to produce state changes. More advanced students can explore models of latent heat and evaporative cooling. This item is part of the Concord Consortium, a nonprofit research and development organization dedicated to transforming education through technology.
In this activity, students will record a list of things they already know about hummingbirds and a list of things they would like to learn about hummingbirds. Then they will conduct research to find answers to their questions. Using their new knowledge, each student will make a hummingbird out of art supplies. Finally, using their hummingbirds as props, the students will play charades to test each other in their knowledge of the ruby-throated hummingbirds. The purpose of this activity is to provide students with information on ruby-throated hummingbirds, provide students with the opportunity to conduct research on hummingbirds in topic areas that interest them, and to provide students with opportunities to share their knowledge with other students. By completing this activity, students will gain knowledge about ruby-throated hummingbirds. They will also gain experience researching a topic of their choosing related to hummingbirds and communicating those results in several different formats.

A 14 week Introduction to Computer Science course.
This course is targeted to middle school grades 6-8 (ages 11-14 years). It is also written for teachers who may not have a Computer Science background, or who may be teaching an “Intro to Computer Science” course for the first time.
This course takes approximately 14 weeks to complete, spending about 1 week on each of the first 11 lessons, and 3 weeks for students to complete the final project at the end. Of course, teachers should feel free to customize the curriculum to meet individual school or district resources and timeframe.
This interactive site allows participants to learn about skeletal anatomy by viewing the bones of a human, chimpanzee, and baboon. The Comparative Anatomy section enables users to make direct comparisons of bones. The material is appropriate for science teacher education as it illustrates how careful observation leads one to wonder about the dizzying beauty of a planet that works by bringing us one different creature after another.
