Leaf cutter ants could be called the overachievers of the insect world. They are farmers, medicine makers, and green energy producers. With support from the National Science Foundation, bacteriologist Cameron Currie studies the complex evolutionary relationships between the ants, the fungi they cultivate and eat, and the bacteria that influence this symbiosis. At the University of Wisconsin-Madison, Currie works with the Great Lakes Bioenergy Research Center on campus to explore how the ants manage to degrade cellulose. Her goal is to discover new ways humans might break down biomass into biofuels. The bacteria component of the ant colony could also help scientists develop more effective antibiotics for human health and agriculture.

It started as a project for long term space survival, when NASA estimated that crews headed to or living on Mars would spend 80% of their waking hours farming. But, with support from the National Science Foundation, research into a leaf sensor that could “call in” with its vital statistics morphed into technology that can help farmers on this planet. The goal is to save water by directly measuring a plant’s moisture level.
Host Alex Dainis explains why leaves change colors during the fall. She examines the different colors of leaf pigments by using chromatography. In this experiment, viewers are able to see the various colors of pigments found in leaves.
Most people see a vegetable when they see a spinach leaf, but in this lab, they see the potential to create heart tissue. Students at Worcester Polytechnic Institute are training to be leaders in bioengineering, and they are thinking outside the box to develop practical, commercially viable technologies that fulfill critical unmet needs. Part of the "Science Nation" series.
Photosynthesis converts light energy from the sun into chemical energy stored in organic compounds, which are used to build the cells of producers and ultimately fuel ecosystems. After providing an overview of photosynthesis, a series of animations describe the inside of the cells of a leaf to explain how the reactions of photosynthesis happen.
One of the fifteen parts of the "Farm to Market" series. A vegetable can be the stem, leaf, root, or even the flower of a plant. Documents the growth, maturation, and harvest of several kinds of vegetables, highlighting their similarities and differences. Follows along as these foods are packaged for market.
Ten 10-minute programs explore temperate and tropical habitats and their abundant diversity of life. Tape one: compares temperate and tropical forests, their habitats, the effects of rain on them, and shows how size can generate great diversity. Tape two: uses butterflies to represent species diversity, compares how people relate to temperate and tropical environments, explores humans' impact on diversity, and investigates issues of threatened and endangered species.
Moko is an explorer. As he travels the world continent by continent, he makes many friends and discovers many natural phenomena which sometimes delight him, and other times scare him. Each animated episode recounts an adventure and takes an "original story" approach to explaining these natural phenomena. In this episode, Moko and Mei-Lei head off to the forest to pick some plants that can't be found anywhere else. Moko is following Mei-Lei's lead as she knows what to do. She picks a leaf and lets it float away, and Moko picks it up. All of a sudden, both his feet sink into the quicksand and he can't get free. Some fishermen come to his rescue and they pull him to safety. Moko and Mei-Lei head back towards the village thinking that the forest is jealous and possessive, since it clearly wanted to keep every leaf and every plant for itself.
Discusses how the activities and processes of cells affect our lives. Covers metabolism, diffusion, respiration, and cell growth and mitosis. Includes questions and a quiz.
1000-year-old Grandfather Tree shares his knowledge about rainforests' plant and animal life, destruction, and importance to world ecology. Voice of Ed Asner.
Students will explore the basic parts of a plant, including the stem, roots, and leaves. This video describes the functions of each of these plant parts using various illustrations. Important terminology includes taproot, fibrous root, stem, sap, nutrients, and leaf.
Explore the vastly different ecosystems of the rainforest and the jungle. This video discusses the diversity of their vegetation, animals, and insects. From the Kool Books series narrated by Hector Bonilla.
Learn about some of the bold and brilliant ideas researchers and conservationists have to rescue corals and coral reefs from disaster. Part of the "Coral Comeback" series.
In this episode, host Emily Graslie interviews Crystal Maier, Collections Manager of Insects at The Field Museum, about her research in New Zealand. She was searching for beetles that spend their entire lives underwater. Part of "The Brain Scoop" series.
In this footage, two citizen scientists are studying butterflies and conducting biological surveys of varied ecosystems in the Red Hills and Apalachicola National Forest. They document the wide diversity of butterflies in the region. Part of the "Roaming the Red Hills" series.
Madagascar has lost almost all of its forests, and the islands population is beginning to encroach on the pristine Makira Forest. Dr. Helen Crowley and her team set off to explore and record the biodiversity of this forest before environmental damage occurs. Segment of video from Wild Chronicles Series.
Is it possible to keep pests out of the environment without using pesticides and herbicides? In this episode, Joel and crew learn how environmentally friendly ways to protect yards and gardens from pests. Part of the Curiosity Quest Series.
Biological vectors carry and transmit diseases that affect plants, animals, and humans. This program focuses on diseases transmitted by mosquitoes and ticks. Students will learn how scientists use the information they gather to help control and prevent the transmission of vector-borne diseases around the world. Part of the "Real World Science" series.
The diversity of rotifers is stunning, and many different species are overviewed. Planktonic rotifers have special adaptations for open water life. Nematodes (roundworms) include a number of important human parasites, seldom seen but easily found. Tree moss, leaf litter, and compost piles swarm with nematodes.
Part of a series that features a wide variety of video footage, photographs, diagrams, graphics, and labels. For this particular video, students will focus on the different types of precipitation including snow, rain, sleet, hail, and freezing rain. Also discussed is the water cycle's role in dispersing perception throughout the world. Part of the Science Video Vocab series.
