Explore the sounds of birds from all over North America in this interactive graphic.

Stare at one color—but see another. You see color when receptor cells (called cones) in your eye’s retina are stimulated by light. There are three types of cones, and each is sensitive to a particular color range. If one or more of the three types of cones adapts to a stimulus because of long exposure, it responds less strongly than it normally would.

This task asks students to glean contextual information about bird eggs from a collection of measurements of said eggs organized in a scatter plot. In particular, students are asked to identify a correlation and use it to make interpolative predictions, and reason about the properties of specific eggs via the graphical presentation of the data.

This PE Game is one of many quick and easy physical education games that teachers can use in their own PE class. It's all about the best games for exercise, skills, activities, games, learning, fitness, and FUN. Simple school games in just minutes. This is a great 3-part progression that has basically 3 games in 1. It’s one of my favourites especially with Kindergartens. Gets players moving around and communicating/strategizing in different ways.

In this Nature video, learn about the extraordinary impact that birds have on the agriculture of a small Indian community.

The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and ideas for extension and support.

Examine how the horrors of the Civil War battlefield forced medicine in America to evolve from a crude practice to a profession grounded in science, in this video from The Good Stuff: Time Capsule.

In this lesson students learn how Birth of a Nation reflected and influenced racial attitudes, and they analyze and evaluate the efforts of the NAACP to prohibit showing of the film.

MIT researcher Deb Roy wanted to understand how his infant son learned language -- so he wired up his house with videocameras to catch every moment (with exceptions) of his son's life, then parsed 90,000 hours of home video to watch "gaaaa" slowly turn into "water." Astonishing, data-rich research with deep implications for how we learn. Deb Roy studies how children learn language, and designs machines that learn to communicate in human-like ways. On sabbatical from MIT Media Lab, he's working with the AI company Bluefin Labs. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 20-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.

The emergence of America as a world power at the end of the 19th century and its acquisition of overseas territories.

It is posed in the context of toppings on cookies ("biscuits" in the UK) and lends itself to multiple representations. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and downloadable handouts.

This task provides the most famous construction to bisect a given angle. It applies when the angle is not 180 degrees.
