Turn light source on to explore. Observe what happens in the observation window as you set up different combinations of light source and molecule. Note this simulation is the first to support our zoom and magnification feature, so zoom in for a closer look, if you need to.

Molecules form when individual atoms create bonds by sharing electrons. Understanding how atoms combine to make molecules allows scientists to predict many of the physical and chemical properties of substances. Since the outermost eight electrons are key to forming compounds, this unit shows how the Octet Rule provides a basis for predicting how atoms may gain, lose, or share electrons to fill the slots in their outer shells. A fundamental understanding of how electrons form bonds leads to the three-dimensional shapes of molecules and has implications in all aspects of chemistry. Part of the series Chemistry: Challenges And Solutions.
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.
Students will explore how molecular movement is related to temperature, and how temperature can be measured. Important terminology includes thermometer, thermal energy, kinetic energy, potential energy, energy conversion, molecules, and heat.
Introduces the concept that everything is made of matter, and examines the three states of matter. Defines and examines a range of solids, liquids, and gases. Uses graphics to show the effects of heat on atoms and molecules in solids. Summarizes each segment.
Diagram of a basic lipid bilayer. Design modalities for the image include braille with and without labels, print with and without labels in greyscale, color, and texture.

Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
Part of the "Inside the Living Cell" series. Illustrates the mechanisms of photosynthesis and cellular respiration. Introduces adenosine triphosphate, or ATP, the universal energy carrier molecules that supply energy-hungry reactions. Also outlines the structure and function of chloroplasts and mitochondria, energy transforming organelles. Overviews ATP and chemical energy, mitochondria, aerobic respiration, chloroplasts, and the reactions of photosynthesis.
The Magic School Bus is an award winning animated children’s television series based on the book series of the same title by Joanna Cole and Bruce Degen. It is notable for its use of celebrity talent and being both highly entertaining and educational. When Wanda's favorite singer, Molly Cule, comes to town, she chooses Ms. Frizzle's class to wash her famous car. The kids clean it from top to bottom, but when Molly insists they missed a spot, they shrink down to see the molecules that make up the car. Only then can they discover how to clean it down to the very last bit. But time is running out. They'll need a molecular miracle to get the car clean before Molly's concert begins.
Matter is made up of tiny particles called molecules. Host, Max Orbit, helps students learn all about the different properties, qualities, and characteristics of matter. He also discusses solids, liquids, and gases. Part of the "Way Cool Science" series.
Meet a chemist who owns his own business that develops synthetic DNA molecules designed to reprogram cells and help cure diseases. Hear the importance of writing, communication skills, and creativity to becoming a successful chemist. Part of the "Career Connections" series.
How can substances, such as water, exist in several dramatically different phases? Easy-to-understand examples illustrate how phase changes occur. Additional concepts and terminology include states of matter, particles, solid, liquid, gas, plasma, melting, freezing, vaporization, boiling, evaporation, condensation, and sublimation.
Carbon is the basis of all organic molecules. It is also one of the most abundant elements in the universe. This video segment illustrates the special characteristics of carbon that make it an essential ingredient for life.
Part of a series that features a wide variety of video footage, photographs, diagrams and colorful, animated graphics and labels. Begins with a simple definition of the term and concludes with a critical thinking question. For this particular video, students will focus on the phases of matter. Part of the Science Video Vocab Series.
The engine's job is to convert the energy in fuel to speed. With the application of scientific principles, NASCAR mechanics have discovered ways to quickly and efficiently get the race cars the speed they need to compete. Part of "The Science of Speed" series.
