An article reviewing how energy flows in a cell including metabolic pathways.

Gross. What is that in the toilet? But maybe it's not just gross. Did you know there are bacteria that digest organic waste and create electrons? What if there was a way to collect those electrons to power a circuit? In this science fair...

In this activity, students learn how engineers use solar energy to heat buildings by investigating the thermal storage properties of some common materials: sand, salt, water and shredded paper. Students then evaluate the usefulness of...

This unit provides students the opportunity to explore methods engineers have devised for harnessing sunlight to generate power. Students will initially explore heat transfer and heat storage through the construction, testing, and...

Students will participate in a laboratory investigation that models the production of silicon. The activity investigates the sources, uses, properties, and importance in the fields of photovoltaics (solar cells/renewable energy) of silicon.

A series of animated illustrations show how a polymer electrolyte membrane fuel cell works. PEM fuel cells are the most common type used in flex-fuel vehicles.

In this interactive activity adapted from the Exploratorium, students will explore how our cells harvest energy from food.

The advantages and disadvantages of hydrogen fuel cell technology as a source for energy production are outlined. There is still much to be done in research and development before this energy source can be marketed widely.

Solar cells provide a clean way of making electricity directly from sunlight. In this project you will build a simple circuit and experimental setup to investigate whether the power output of a solar cell changes with ambient temperature.

The lesson will first explore the concept of current in electrical circuits. Current will be defined as the flow of electrons. Photovoltaic (PV) cell properties will then be introduced. This will lead to the principle of "Conservation of...

Explains oxidative phosphorylation, which is the fourth step of cellular respiration, and produces the most of the energy in cellular respiration.

Chapter 22 of a report on the energy industry in Texas. It looks at hydrogen as an energy source, its history, and uses. The economic impact of the hydrogen energy sector in Texas is described, the consumption of hydrogen, methods of...

A great page for all around biochemistry and background information. Includes the molecular structure and most of the information relevant to its role in living cells.

Four science projects in which students learn how solar energy works and how thermal energy is transferred and utlized in a solar air heater, a solar water heater, a solar hot dog cooker, and a solar cell.

[Free Registration/Login Required] An informational text about solar cells being made of plastic. A question sheet is available to help students build skills in reading comprehension.

Learn all about cell membranes in this game. Build a plasma membrane and learn about the membrane's functions. Identify the parts of a membrane, and learn how diffusion, transport, and osmosis work in cells. Includes a worksheet that can...

In this activity, students explore how an electrochemical cell works. They use a Voltage Sensor to measure the electrical energy produced when the distance between the electrodes is varied. They also determine the factors that affect the...

In this activity, students' will use fruits and vegetables to make an electrochemical cell and develop an understanding of how an electrochemical cell works. They will use a voltage sensor to determine which fruits and vegetables produce...

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to electrochemistry. In particular, this site explores a range of topics related to batteries and fuel cells.

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...
