Can you use a solid to study fluid dynamics? You bet! Science scholars examine the process of fluidization with a video from an extensive physics playlist. The narrator demonstrates and explains how the uniform movement of air causes...

If you look close enough, sand can tell you a story. A video lesson describes the creation of sand over time. Scholars explore how different types of sand have come to be and the different materials found in a sample of sand.

Here's an unusual approach to ensuring the survival of a species! Introduce young biologists to the California grunion, a fish that mates on land rather than in the water. The video shows how grunion make use of time and the tide to...

On June 7, 1692, at 11:43 am, the Jamaican city of Port Royal sank into the harbor, killing more than 2,000 people. The video explains this disaster and others that were caused by liquefaction, describes the conditions required, and...

We find sand on beaches, sand dunes, timers, and in hydraulic fracturing, but what exactly is it? The video discusses the mineral that composes the majority of sand on the planet. It also explains how it forms and why it ends up near...

Get them thinking big about chemistry! Young chemists learn about the large and elaborate structures created through covalent bonding in the fourth of a six-part video series regarding elements, mixtures, and compounds. The video covers...

A hydrophobic substance (water hating substance) is added to differently colored sand which means that when the sand is dumped into a bowl of water, it doesn't get wet - at all! This is an impressive trick, and is easy to do. All you...

The goal of this video lesson is to relate physics principles to natural phenomena, while simultaneously incorporating the context of global and environmental issues. [47:36]

Learn how the different geological components that make up sand are formed. [2:28]

Sand, no matter how you use it, is pretty much the same just about anywhere you go. But why does sand almost always look the same? Much of the world's sand is made up of the same materials--tiny crystals of mineral quartz, which is made...

A scientist teaches students how to gather evidence and make scientific inferences about the beach just by looking at the sand. [9:23]

Geologist Dr. Jeff Warren shows how the beach is built and performs a "fizzy" experiment with beach sand to show evidence of its physical and chemical composition. [8:14]

Find out about Wisconsin's delicate freshwater estuary environments along Lake Superior. Includes ecosystems in the Apostle Islands in addition to the Flag, Cranberry, Bark, Sand, Rasberry, Lost Creek, Whittlesey Creek, Fish Creek,...

In this Dinosaur Train clip, Shiny and Don build a sand castle for Henry and Stella. When water destroys it, they learn that change is a natural part of life. [3:20]

Observe how rivers meander and how the water deposits rocks and pebbles on the inside of each curve. Watch kids use the scientific method to find out how rivers affect the earth's surface.
