An interactive applet and associated web page that demonstrate the concept of coplanar objects - those that lie in the same plane. The applet presents two planes. In one plane there are two rectangles that can be dragged around and which lie in the same plane always. The other is a rectangle that can be dragged but always lies in a plane orthogonal to the first. Applet can be enlarged to full screen size for use with a classroom projector.

This lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. Biomimicry involves solving human problems by mimicking natural solutions, and it works well because the solutions exist naturally. There are numerous examples of useful applications of biomimicry, and in this lesson we look at a few fun examples.

An interactive applet and associated web page that provide step-by-step instructions on how to copy a line segment using only a compass and straightedge. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector.

An interactive applet and associated web page that provide step-by-step instructions on how to divide a line segment into any number of equal parts, using only a compass and straightedge. The applet starts with a given line segment and ends with that segment divided into n parts. In the applet n=5, but the construction works for any n. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. The text on the page has printable step-by-step instructions.

This week, Stan Muller teaches you the basics of copyright in the United States. Copyright law is territorial, so we're going to cover the system we know the most about, and that's the US. Stan will talk about what kind of ideas can be copyrighted, who can get a copyright, and what protections the copyright grants. We'll also talk about the always contentious and seemingly ever-growing term of copyright. Stan will also teach you about the low bar for creativity, which means that original work doesn't have to be all that original, and he'll also touch on the problems with copyright in the modern world.

Copyright & Creativity for Ethical Digital Citizens is a full K-12 suite of resources for teaching copyright, fair use, public domain, and Creative Commons. They have free resources for educators, which include:
• in-class lesson plans
• plug-n-play lesson slides
• independent learning videos
• visual aids
• a professional development course for teachers
All resources were developed on a nonprofit basis with input from independent educators, academic copyright experts, and online civil liberties advocates.

Stan Muller teaches you a few things about copyright enforcement, and talks about the exceptions to copyright enforcement. While there are several, the one you've probably heard of is Fair Use, and it's a pretty tricky one. We'll try to explain it, and teach you just why fair use is so loosey goosey.

This lesson takes advantage of students' interest in music and audio sharing. Students investigate multiple perspectives in the music downloading debate and develop a persuasive argument for a classroom debate.

Students investigate how and why copyright law has changed over time, and apply this information to recent copyright issues, creating persuasive arguments based on the perspective of a particular group.

In our Avoiding Plagiarism module, we gave you tips for citing, quoting, and incorporating various sources into your writing projects. However, depending on what types of sources you use, you may also have to consider copyright and fair use laws. For example, if you want to use someone else's photo or song in one of your own projects, you'll need to make sure you have the legal right to do so. In this tutorial, you'll learn about the copyright protections that apply to work posted online, including images, text, videos, and more. You'll also learn about the rules that determine which of these resources you can use, and how you can use them.

DESCRIPTION
Copyright and fair use are crucial topics for educators. In today’s digital world, copyright and fair use are also directly relevant to activities that students engage in virtually every day. This short course aims to make these concepts clear and accessible to educators. Completing this course should give educators the background they need to feel comfortable teaching these concepts to students using Copyright and Creativity for Ethical Digital Citizens, our free suite of K-12 teaching resources.

OBJECTIVES
At the end of this course, you’ll be able to:

Understand the purpose of copyright and its basic rights.
Understand the limitations of copyright, including fair use.
Understand how to acquire and share media in lawful and ethical ways.
Be prepared to apply copyright and fair use to project-based learning situations, including knowing how to help students find creative work that is free and legal to re-use and share.

Corals are beautiful, diverse and complex structures. Nearly everyone knows about Coral Reefs, but do you know what they actually are...? Coral Reefs are vital animals that provide the foundation for the richest diversity in the ocean. Explore the important role that corals have for the oceans worldwide, and understand how our small choices can have a powerful impact on life in the ocean.

In this activity, student teams identify the locations of coral reefs around the world, examine infrared satellite images of the Earth, and research the impacts that are threatening the survival of coral reefs. Each team creates a short oral presentation describing the coral reef they have researched. Students then plot on a composite map the locations where coral bleaching is occurring. Student worksheets, a teacher guide, and assessment rubric are included. This activity is part of Coastal Areas: Coral Reefs in Hot Water, part of the lesson series, The Potential Consequences of Climate Variability and Change.
