STEM Resources Collection

This collection of STEM instructional resources focuses on all things Kentucky. Teachers and students have access to video and images from award-winning KET programs, with educational support materials developed in line with state academic standards. Topics include life sciences, geometry, and biology.

  • Inverse Square Law

    This animation, originally created for a KET Distance Learning physics course, explains the mathematical formula for the "Inverse Square Law" by demonstrating how the brightness of light changes with the distance from a source in one, two, and three dimensions. This animation can be viewed in segments or as a whole.

    Grades: 7-13+
  • Making Electricity at a Coal-Burning Plant

    Learn the process of how electricity is made at a coal-burning plant in this video clip.

    Grades: 6-12
  • Calcium for Horses

    Watch this animated segment from KET's Electronic Field Trip to a Horse Farm to learn why Kentucky is known as one of the best places to develop strong, fast horses. See a brief demonstration of a horse's digestive process to learn how naturally calcium-rich grass is broken down into carbohydrates, proteins, minerals, and vitamins, and how calcium is then absorbed into the bones.

    Grades: K-4
  • What Is a Watershed?

    Runoff from fields, lawns, and pavement could carry potentially harmful materials from our watersheds to our rivers. Even if you live, work, or play far from a river, your actions could have an impact on the quality of the water in the area. These effects could be felt far from the point of origin. This video from KET's Raindrops to Rivers shows how smaller watersheds flow into larger ones.

    Grades: 6-12
  • The Cumberland Gap Tunnel

    The Cumberland Gap once served as a major overland gateway to the west. Today, automobiles are the preferred method of travel through this break in the Appalachian Mountains. This KET video is an account of the Cumberland Gap tunnel, the engineering marvel that moved a road under a mountain.

    Grades: 6-12
  • Unique Species of Kentucky's Green River

    In this KET video from "Kentucky's Last Great Places", take a trip on the pristine Green River to find out why it has remained so clean despite the widespread pollution of the modern age. Scientists demonstrate how the health of the river can be measured by indicator species, such as mussels and crayfish, and showcase some of the global endemics-species that exist nowhere else-found in the Green River, such as the orangefin darter.

    Grades: 6-12
  • Vehicle Stopping Distance | Street Skills

    If you are traveling 20 mph, how far would your car go before stopping? This video, adapted from KET's Street Skills, explores the two parts of the stopping process: reaction time, how long it takes your brain to respond, and stopping distance, the distance traveled between putting on the brake and coming to a stop.

    Grades: 6-12
  • Urban Solutions to Water Pollution

    In this KET video segment from Louisville Life, learn how a rain garden in an urban community helps prevent storm water runoff from contaminating an urban watershed. Students describe how building a rain garden helps improve their community, prevents storm water runoff, and provides a personal sense of accomplishment and pride.

    Grades: 6-12
  • How The Ohio River Was Formed

    This video segment, adapted from Where the River Bends, a KET documentary, shows how climate change and glacier movement during the Ice Ages caused the now-vanished Teays River to move to the south and become the Deep Stage Ohio River. Listen to a local historian describe how the advance and retreat of the Wisconsin Glacier about 100,000 years ago caused the path of the Deep Stage Ohio River to change, creating the course of the modern Ohio River that impacted the growth and development of the region.

    Grades: 6-12
  • Indiana Bats of Carter Cave | Kentucky Life

    In this KET video segment from Kentucky Life, explore Bat Cave to find out how endangered Indiana bats are being protected. Learn about the efforts to help the endangered bats from naturalist Sam Plummer who explains why the bats are important and the role humans play in their habitat destruction and protection.

    Grades: 6-12
  • Points of Origin

    This animation from KET illustrates how an origin is used for positive and negative measurement along a straight line and on a flat plane. It also shows how an origin, latitude, and longitude identify locations on Earth and explores how measuring temperature differs from measuring height or weight.

    Grades: 4-8
  • Quantus

    Learn about the use of quantification, coordinates and basic foundations of model construction and animation using a computer.

    Grades: 6-12
  • Dragonflies in Kentucky | Kentucky Life

    In this KET video segment from Kentucky Life, learn about dragonflies and damselflies. See these beautiful insects in flight, and learn about their habitats from a biologist.

    Grades: 6-12
  • Restoration of the American Chestnut | Kentucky Life

    In this KET video segment from Kentucky Life, learn how a majestic old chestnut tree that miraculously survived the blight is being preserved, studied, and pollinated under the watchful eye of scientists. See the precise process the scientists use to control the pollination of the flowers in order to study the offspring for resistance to blight. Watch as the scientists return four months later to harvest the nuts.

    Grades: 6-12
  • Farm Solutions to Water Pollution

    Farming has always meant more than cultivating crops and raising animals. In this KET video from Common Ground and Cleaner Water, learn from a third generation farmer what it means to protect the land for future generations by caring about water quality on his farm and on his neighbors' farms down stream. See how building a containment pond helps prevent animal waste from polluting streams and helps fertilize crops.

    Grades: 6-12
  • Thank Goodness for Gravity

    The boy featured in this video has concerns about spinning through space on Earth until he is introduced to a Foucault pendulum. He learns that French scientist Jean Bernard Léon Foucault used his knowledge of pendulums to demonstrate Earth's rotation and how that movement is a steady, measurable motion rather than a dangerous one. KET adapted this video from the original produced by the Lexington Public Library in Lexington, Kentucky.

    Grades: 3-6
  • The Falls of the Ohio

    In this video from KET, stroll along the Falls of the Ohio River, one of the largest exposed fossil beds in the world. Imagine what this part of the Midwest looked like during the Devonian Period, 387 million years ago. Fossil evidence of corals and other marine organisms indicate the region was located in the tropics and was covered by a warm, shallow sea.

    Grades: 6-12
  • Pixels and Pigments

    Learn about pigments, the subtractive color model and how pixels depict color on a monitor according to numeric value.

    Grades: 6-12
  • Karst Topography and Mammoth Cave

    In this video from KET, take a trip into the depths of Mammoth Cave and ride an airplane to view sinkholes in the land above the Mammoth Cave system in Kentucky. Watch as an animation shows how both caverns and sinkholes are created by water seeping through and dissolving limestone. Discover that much of Earth's land surface is karst, similar to that in the Mammoth Cave region, and thus shares the water quality issues prevalent there.

    Grades: 6-12
  • American Chestnut Tree | Electronic Field Trip to the Forest

    See the devastating impact of blight on the American chestnut tree in this annotated slideshow adapted from KET's Electronic Field Trip to the Forest. Learn the scientific processes scientists use to identify the remaining trees, document their locations, and cross-pollinate them with other varieties of chestnut trees to create hybrids that are blight-resistant.
