Dive into cave weathering and erosion! Caves are hollow spaces underneath the earth’s surface with openings large enough for a person to enter. Many caves form in a karst environment, a type of landscape made of rocks like limestone, or dolomite, that slowly dissolve in the presence of water with a slightly acidic tinge. There are several different types of caves, and they are named by how they are formed. The most common type of cave is a solutional cave, a cave formed by the chemical reaction of water with limestone bedrock. While chemical weathering gets things started, caves continue to develop over time through ongoing physical and chemical weathering, as well as erosion.

Today’s podcast focuses on the field of meteorology and the forces that create weather patterns and natural phenomenon like rain, thunder, and lightning. The kids discuss and explain how the weather is predicted and how it affects our everyday lives. Weather changes can be caused by temperature shifts that affect our atmosphere and cause the air to move differently. A meteorologist is someone who studies and predicts weather patterns and helps us understand what is going on in our atmosphere.

Today’s Walking Classroom podcast discusses hot springs and geysers, two related types of hydrothermal activity found in areas near volcanoes. Hydrothermal comes from two Greek words, hydro meaning water and therme meaning heat. Hot springs form when water that has risen to the surface of the earth collects in heated pools while geysers shoot fountains of water and steam into the air. Hydrothermal activity occurs all over the world, but is observed mostly in Iceland, New Zealand, and Yellowstone National Park.

Today’s Walking Classroom podcast focuses on the circulatory system. The circulatory system is made up of the heart, blood vessels, and blood. They all work together to deliver oxygen to the cells of your body and dispose of carbon dioxide waste. The heart is divided into four chambers, and each chamber has a special job.

Today’s Walking Classroom podcast focuses on the body’s defense shields, which are sometimes a bit slimy. The human body protects us through various defense systems and communicates various health conditions. Earwax, mucus, and sweat are among some of the defense systems that help keep us healthy and safe. Some things we normally think are gross can actually be important; it is valuable to appreciate the purpose in everything.

Today’s Walking Classroom podcast discusses America’s great humanitarian, Clara Barton.
