Dr. Forrester discusses how environmental process and characteristics affected the settlement of New Orleans and how the environmental disaster of Hurricane Katrina affected the area in 2005.

Dr. Forrester teaches the student about the following terms and physical features: sea level, elevation, bayou, plateau, levee, hurricane, Mississippi embayment, barrier islands, plains, wetlands, Mammoth Cave, and Jockey's Ridge.

Hurricane Katrina describes how geography affects climate and weather by examining Hurricane Katrina as an example.

Sea levels are rising. For many cities on the the eastern shores of the United States, the problem is existential. We take a look at how Miami and Atlantic City are tackling climate change, and the challenges they face under a skeptical...

What's The HIGHEST ALTITUDE Humans Can SURVIVE? Take away oxygen masks and pressurized suits and what is the highest limit of human survival?

Commercial airplanes typically fly between 32,000 feet and 38,000 feet, with the sweet spot being approximately 35,000 feet. One of the main reasons commercial airplanes fly so high is air resistance. You see, the higher you go above the...

Graphs shouldn't be scary! They're just data! And even though I have a masters degree in environmental studies, this graph, once it was explained to me, changed how I felt about the impacts we were having on the planet completely. Of...

This video explores five fun facts about Mount Everest.

Dive to the deepest point of the ocean with an astronaut, brave the high seas with an oceanographer, and meander through sparkling rivers with a hydrologist.

Sound Wave Experiments In this video, we are going to look at the factors that influence the speed of sound and how to measure it. We will look at sound waves in more detail in another video: Sound Waves Sound travels at about 340m/s in...

In this lesson, students will learn about positive and negative quantities in the real world through various examples. They will understand that positive numbers represent quantities above zero, while negative numbers represent...

In this video, the teacher explains how to graph square root functions by creating a T-chart. They demonstrate how to find the square root of perfect square numbers and plot the corresponding coordinates on a graph.

We just learned about the different types of rock deformation, so now let's get a closer look at some more specific structures. First we have faults, which can be normal, reverse, and strike-slip or reverse faults. We should also take a...

Hurricane Sandy was the deadliest of the 2012 hurricane season and is the second costliest hurricane in U.S. history! While many scientists will be studying ""Sandy"" for years to come, some researchers are focused instead on how to make...

Upon viewing the Forces in Fluids video series, students will be able to do the following: Define fluids as substances that can easily flow and readily change shape. Explain that fluids flow because particles can easily move past each...

Hurricane Sandy was the deadliest of the 2012 hurricane season and is the second costliest hurricane in U.S. history! (Only the damage from 2005's Hurricane Katrina cost more.) While many scientists will be studying "Sandy"...

At the Plum Island Sound estuary in northeastern Massachusetts, the marsh floods like clockwork. At high tide, you can pass over the mudflats into the grass in a boat. At low tide, the ocean waters recede, leaving behind fresh deposits...

Antarctic ice sheet melting could increase sea levels by over five meters by the year 3000 if current warming trends continue.

In this lesson, students will learn how positive and negative numbers are used to measure elevation above and below sea level. They will understand that sea level represents 0 elevation, and that both positive and negative elevations...

Of the five major classes of phylum Cnidaria, we have just one more to cover, and that's Anthozoa. These are "flower animals", or polyps that lack a medusa stage, such as anemones, corals, sea pens, and more. Let's take a look at these...

A team of researchers led by the University of Vermont and the U.S. Geological Survey have confirmed that the sea level in the Washington, DC region is rising faster than the rest of the East Coast, due not only to global warming but...
