Watch how the winds of a large Arctic cyclone broke up the thinning sea ice cover of the Arctic Ocean in early August 2012. The storm likely contributed to the ice cap's shrinking to the smallest recorded extent in the...

Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again,...

From the South Pole to Greenland, from Alaska’s glaciers to Svalbard, NASA’s Operation IceBridge covered the icy regions of our planet in 2017 with a record seven separate field campaigns. The mission of IceBridge, NASA’s...

We've learned a few separation techniques, so how about one more? Chromatography separates components of a mixture by virtue of their differing polarities, and thin layer chromatography, or TLC, is an invaluable technique that is used...

In this section, I talk about the properties of water, and what makes it unique. I talk about hydrogen bonds that result from the polar nature of water and why ice floats.



I also deal with diffusion and go into the 3 factors...

The plasma membrane is responsible for maintaining a balance. In this section, I talk about both the structure and the function of the plasma membrane. I deal with the components of the plasma membrane and their functions.

The Guardian reports that a study by the Chinese Academy of Sciences has found that recent human activity has shifted the Earth’s axis by an unprecedented margin.

Polar bears live near the North Pole, a frigid region covered by white ice and snow. The bears are protected by their thick, white fur. But what makes a polar bear’s fur white? In this episode of Earth Rangers, an expert on polar bears...

Exam Review Convert a polar point to rectangular form

Learn how to convert points between rectangular and polar. Rectangular points measure the horizontal and vertical distance away from the origin whereas polar coordinates measure the direct distance and angle in standard position from the...

Convert polar coordinates to rectangular coordinates

We learned about ideal gases, as well as kinetic molecular theory, which explains the laws that govern ideal gases. But some of the postulates of this theory won't always hold true. When a gas is highly pressurized and/or very cold, it...

Cartesian and polar coordinates are introduced and how to switch from one to the other is derived. The concept of angular displacement and arc length are demonstrated. Circumference is shown to be an arc length.

This live-action video program is about the word adapt. The program is designed to reinforce and support a student's comprehension and retention of the word adapt through use of video footage, photographs, diagrams and colorful, animated...

This live-action video program is about the word Climate. The program is designed to reinforce and support a student's comprehension and retention of the word Climate through use of video footage, photographs, diagrams and colorful,...

Of all the far-flung worlds explored by NASA, the most important may be our own....<b<br/>r/>

Learn how to represent polar points in multiple ways. Recall that angles that are coterminal are exactly the same. So, we can represent polar points in multiple way by representing its coterminal angles. One of the closest coterminal...

This program begins by explaining how scientists have learned that Earth’s climate has changed many times over billions of years and that Earth’s climate is...

Why are habitats important? Live-Action footage of animals and colorful animation help students discover the answer. This program takes viewers around the world to explore the tundra, desert, grasslands, forests and waterways of the...

Ionic Bond, Covalent Bond, James Bond, so many bonds! What dictates which kind of bond will form? Electronegativity values, of course. Let's go through each type and what they're all about.

Weather forecasting requires observation. Beyond the things we can see, hear and sense, meteorologists need detailed data to observe distant weather, whether that is distant along the ground, or distant up into the sky. Weather...

Learn what intermolecular forces are, the three most common types and the differences between them. An intermolecular force is simply an attractive force between neighbouring molecules. There are three common types of intermolecular...

We each have between 30 and 40 trillion cells in our body. With each cell containing our DNA, special cell machinery and the nutrients to keep our cells and us alive. But you may not have given much thought for the special protective...
