This interactive site provides animations and activities in several areas of physiology. The images are simple, but clear. The accompanying text provides a good description of the process being shown.

A tutorial that looks at the connection between photosynthesis and cellular respiration.

A good biochemistry site that includes information about the structure of adenosine triphosphate and a description of the role that it plays in the cell.

A novel idea for converting solar energy to electrical energy. A brief discussion of solar energy collection in space via satellites.

[Free Registration/Login may be required to access all resource tools.] Energy is the ability to do work. In organisms, this can be physical work, like walking or jumping, or it can be the work used to carry out the chemical processes in...

This lesson focuses on what happens during cellular respiration including how energy is released as APT and why organisms need energy in that form. A link to a test is provided.

A great description of the global scale circulation and heat energy. Discusses a single-cell model, a three-cell model, jet streams and more.

Students test whether the color of a material affects how much heat it absorbs. Students will place an ice cube in a box made of colored paper (one box per color; white, yellow, red and black), which they will place in the sun. The...

Taking advantage of free energy can reduce our dependence on fossil fuels, which are harmful to our environment. In this science fair project, you will work with a solar panel, which is a collector of free energy, and investigate how...

Solar power is hot these days. Gleaming, black solar panels soak up rays on more and more rooftops of homes and businesses providing a clean, alternative source of heat and electricity. You might guess that different times of the day...

A basic explanation of how chloroplasts and mitochondrion produce energy within the cell. Various terms presented are explained in a clear and easily understandable manner.

Learn how food is broken down to produce energy for cells in the in the form of ATP in this interactive tutorial.

Students will learn about both POP Art and science in this pattern project. Working in conjunction with a science teacher in your school, students will view cells through a microscope and use visual diaries to create pattern templates....

In this unit, students explore a variety of phenomena to figure out, "Why do things sometimes get damaged when they hit each other?" Student questions about the factors that result in a shattered cell phone screen lead them to...

Discusses electric forces, electric fields, electric potential, and the role that electric potential plays in enabling materials to pass through a cell membrane.

Students learn about how cells fuel themselves by examining how carbon dioxide is produced by yeast cells when the cells feed on sugar. The carbon dioxide is detected through the use of a red cabbage indicator that reacts in the presence...

In the body, oxygen forms a vital role in the production of energy in most cells. Enda Butler tracks the surprisingly complex journey of oxygen through your body.

We've seen them for years on rooftops, atop highway warning signs, and elsewhere, but how many of us know how solar panels actually work? How do the photovoltaic cells that lie at the heart of them turn sunlight ("photo") into...

We encounter electrochemical cells in all facets of our everyday lives. Learn about the two types of electrochemical cells: galvanic, also called Voltaic, and electrolytic. Discusses the reactions that take place in cells, the formulas...

Students form expert engineering teams working for the (fictional) alternative energy consulting firm, Greenewables, Inc. Each team specializes in a form of renewable energy used to generate electrical power: passive solar, solar...

In this experiment, students observe what happens when a pan of soapy, colored water is heated. They will see that convection currents cause the fluid to rise and sink in a localized convection cell.

Article presents an in-depth overview of oxidative phosphorylation which provides most of the ready chemical energy (ATP) used by the cells in your body.

Frankenstein's electricity is out. In this activity, students help him find another source of energy using citrus fruit. Good for students who want to do their own projects or for class lessons.

A large part of engineering involves presenting products, concepts, and proposals to others in order to gain approval, funding, contracts, etc. The purpose of this activity is to fine-tune students' presentation skills while allowing...
