Introduction to the intuition behind limits
This 7:38 video introduces limits used in calculus. A limit is the value of the expression as the expression approaches. This introduction gives examples that show that limits are not as simple as just evaluating a function. The video uses a narrator and a smart board.
TED Ed--How Folding Paper Can Get You to the Moon
Can folding a piece of paper 45 times get you to the moon? By seeing what happens when folding just one piece of paper, we see the unbelievable potential of exponential growth. This lesson will leave you wanting to grab a piece of paper to see how many times you can fold it! (3:49)
Anatomy of a Volcano (Interactive)
Volcanoes repeatedly remind people of Earth's potential for violence. Since 1700, volcanic eruptions have killed more than 250,000 people and devastated scores of communities. What causes these dramatic geologic displays? This interactive activity from NOVA Online provides a detailed look at the inner workings of one of the world's most dangerous volcanoes, Nyiragongo in the Democratic Republic of Congo.
Antarctic Food Web (Interactive Game)
This interactive game adapted from the Bigelow Laboratory for Ocean Sciences challenges players to build a food web, a complex model that shows how various food chains in an ecosystem are connected. Players must position the names of producers and consumers in the correct places in a diagram. The completed diagram reveals how energy flows through an Antarctic ecosystem and the relationships between predators and prey.
TED Ed--How Simple Ideas Lead to Scientific Discoveries
Adam Savage walks through two spectacular examples of profound scientific discoveries that came from simple, creative methods anyone could have followed -- Eratosthenes' calculation of the Earth's circumference around 200 BC and Hippolyte Fizeau's measurement of the speed of light in 1849. This is a great resource to help build background knowledge and to help make real world connections in the classroom. (7:32)
TED Ed--The Secret Life of Plankton
New videography techniques have opened up the oceans' microscopic ecosystem, revealing it to be both mesmerizingly beautiful and astoundingly complex. Marine biologist Tierney Thys teamed with Christian Sardet (CNRS/Tara Oceans), Noé Sardet and Sharif Mirshak to use footage from the Plankton Chronicles project to create a film designed to ignite wonder and curiosity about this hidden world that underpins our own food chain. (6:02)
Tale of the Shepherd Planets
A quote from the movie: "Until recently, the search for planets beyond our solar system was a matter of calculating the odds and laying out theories of solar system formation. Circumstantial evidence began to trickle in, a color shift in a stars light as a planet tugged on it, or a dipping in its light as a planet passed in front." (04:50)
TED Ed--Evolution of Animals in a Big City (Animal Adaptation)
Using newts, coyotes, and mice, Jason Munshi-South shows how animals develop genetic differences in evolution, even within an urban city. This is a great resource to help build background knowledge and would work well in conjunction with lesson/unit on animal adaptation. (5:16)
Undressing Extraordinary (1901)
Classic comedy or early horror? A sleepy traveller finds taking his clothes off more difficult than usual in this beautifully timed treat from British trick film pioneer W.R. Booth. Do you find it funny or unnerving? Contemporary opinion was apparently divided.

Nanoengineered Surfaces for Efficiency Enhancements in Energy and Water Thermal-fluid-surface interactions are ubiquitous in multiple industries including Energy, Water, Agriculture, Transportation, Electronics Cooling, Buildings, etc. Over the years, these systems have been designed for increasingly higher efficiency using incremental engineering approaches that utilize system-level design trade-offs. These system-level approaches are, however, bound by the fundamental constraint of the nature of the thermal-fluid-surface interactions, where the largest ineffici
