There are some geological areas on the planet that scientists still don't understand. For most things it's pretty clear—combine a volcanic eruption a dash of erosion, and boom, you’ve got a striking cliff! But not all the features on...

Hank gives us a summary of the important facts about fracking: what it is, why we do it, and how it actually isn't all butterflies and cupcakes.

Wouldn’t it be cool to be able to point at a fossil and know that it’s the first, say, plant? Well... yeah! But it's not that easy! Scientists are always making new discoveries that throw all our old assumptions into...

Watch the first part of our Carbon Cycle videos, as part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

Prof. Mike Stephenson: When it comes to fracking, people don't know what's true or false.

Watch part 2 of the videos on the Carbon Cycle, as a part of environmental chemistry. Photosynthesis and respiration help carbon to be cycled in nature by using energy from the sun. As living things grow, they have to build up large...

The basic nuts and bolts of how things work is explained simply by exploring the natural world and human made inventions that we come in contact with. Cement is a common construction material. How is this hard, durable substance made?...

Upon viewing the The Rock Cycle video series, students will be able to do the following: Explain that rocks are non-living substances made up of one or more minerals. Understand that a mineral is a natural substance with a definite...
