Arctic Climate Perspectives
This video, adapted from material provided by the ECHO partners, describes how global climate change is affecting Barrow, Alaska.
Rocket Me into Space
One of the exciting challenges for engineers is the idea of exploration. This lesson looks more closely at Spaceman Rohan, Spacewoman Tess, their daughter Maya, and their challenges with getting to space, setting up satellites, and exploring uncharted waters via a canoe. This lesson reinforces rockets as a vehicle that helps us explore outside the Earth's atmosphere (i.e., to move without air) by using the principles of Newton's third law of motion. Also, the ideas of thrust, control and weight
Tidal Streams in Massive X-ray Binary Systems: Neutron Star Close-up
A tiny neutron star orbits incessantly around a massive star with a diameter a million times larger than its own. The high luminosity of the massive star drives a strong wind from its surface. The neutron star crashes through this wind at over 300 kilometers per second. The gravity and X-ray luminosity of the neutron star act to disrupt the wind, producing an extended wake of dense gas trailing behind the neutron star. In this simulation, the tidal distortion of the primary star and the resultan

Writing exercise: A tidy neighbourhood
After this chapter you will be able to explain to a friend in a short note what happens in your area.
Algorithms for Sorting Arrays
It is often necessary to have elements of an array sorted into ascending or descending order. There are several approaches or algorithms available for sorting unordered arrays. Choosing an appropriate algorithm may depend upon the situation, however, some well-known algorithms are just more efficient than others.
Common Core Curriculum Maps
Common Core has released a free, First Edition of the K-12 Curriculum Maps in English Language Arts. The Maps are designed to help educators meet the expectations of the Common Core State Standards, which call for the standards to be “complemented by a well-developed, content-rich curriculum
How to Ace a Job Interview
This 2:11 minute video provides some insights into how to prepare for a job interview. It is built around doing your homework before going in for the interview.
Saving the Bald Eagle
The national bird, the Bald Eagle, is back in the lower 48 states after nearly disappearing in the 60's and 70's. Robert Mesta, a biologist with the U.S. Fish and Wildlife Service, explains what it takes to recover a species like the bald eagle, and demonstrates how math plays a critical role in the process.

Multiplication Rule (Probability "and")
The instructor, while using computer software, discusses the multiplication rule in probability. The instructor talks a little fast, so this video will be more helpful if a classroom teacher supplements this information with prior discussion. (03:24)
Review 2 - Computer Science 61A Fall 2007
Review 2. From CS 61A The Structure and Interpretation of Computer Programs - Fall 2007. Introduction to programming and computer science. This course exposes students to techniques of abstraction at several levels: (a) within a programming language, using higher-order functions, manifest types, data-directed programming, and message-passing; (b) between programming languages, using functional and rule-based languages as examples. It also relates these techniques to the practical problems of imp
