What determines how many species live in a given place? Or how many individuals of the species can live somewhere? The research that provided answers to these questions was set in motion by the key experiments of ecologists Robert Paine and James Estes. Their research demonstrates just how fundamental keystone species and trophic cascades are in understanding ecology.

Climb aboard the Cyclops, a microscopic research vessel, and investigate an amazing hidden world on which all living things depend. The Cyclops houses a team of scientists known as the Micronauts and guides them through their discoveries of biological classification, diversity, and ecology. In this clip, the Micronauts explore the process of photosynthesis. They conduct experiments using paramecium by observing the green algae cells within its body. Through their experiments, they realize the in the presence of light, the green cells generate oxygen and food molecules. Part 2 of the Microscopic Monsters Series.
Chemistry is the science of interacting particles and the various states of matter. Developing a better understanding of the atomic model through experiments with gases, scientists discovered the Ideal Gas Law, developed phase diagrams, and learned about the properties of supercritical fluids. Today's chemists are exploring new ways to control the interactions of atoms, with the goal of making better hydrogen-powered cars and new technologies for the long-term, underground storage of carbon dioxide to reduce greenhouse warming. Part of the series Chemistry: Challenges And Solutions.
Observe changes to electrostatic force as you play with the distance between charges and charge amounts at both macro and atomic scales.

Students will learn how light is measured. Visual diagrams and hands-on experiments help students understand how light works. Important terminology includes wave, electromagnetic spectrum, wavelength, energy, reflection, lens, and prism.
Presents general information about the scientific method and identifies its steps. Gives simple examples of how it is used in daily life and restates the steps several times.
Host Lisa Van Pay meets with NSF-funded scientists Yang-Shao Horn and Yogi Surendranath at the Massachusetts Institute of Technology as they take on the hydrogen energy challenge.
Shows the combustion of magnesium, a thermite reaction to form iron, and the chemical reactions of sodium and potassium with water.
Play with John’s foot and arm to explore when he gets a zap!
Observe changes to the equation and wire as you play with the resistivity, length, and area sliders.
Build sandwiches, then investigate molecules to explore reactants products and leftovers. Note this sim does not yet have a Keyboard Shortcuts dialog, and simple descriptions are in progress.
Uses practical examples to help students understand and use the components of the scientific method. Concepts and terminology: hypothesis, experiment, measuring, data, analysis, and conclusion.
What is electricity and how is it made? What kinds are there? What are circuits and switches? Is electricity dangerous? Answers these questions with easy-to-duplicate experiments.
Demonstrates how to observe and record scientific observations. Concepts and terminology: observation, data, recording, data table, tools, safety, measuring, and graphs.
Dr. Ronald Evans reviews how cell receptors called PPARs regulate body weight by controlling fat burning or storage. Part of the 2004 Howard Hughes Holiday Lecture Series.
In this episode, host Alex Dainis takes viewers on a tour of her lab. She points out important equipment and tools and explains their purpose in the conducting scientific experiments.
Meet a food scientist who overcame his fear of chemistry, and now conducts experiments with vegetables. Part of the "Career Connections" series.
Demonstrates the production and collection of hydrogen in a chemistry lab, and testing of its purity. Also shows and explains other chemical reactions related to this element.
Dr. Ronald Evans describes how fat communicates with muscle and how diet and exercise influence that relationship. Part of the 2004 Howard Hughes Holiday Lecture Series.
Think all squash balls bounce the same? Think again! Two MIT scientists look into what makes things bounce better than others. Ready for some physics? Part of the "Science Out Loud" series.
