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

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.

[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.

In this life science classroom activity, students will use cooperative learning and whole class discussions to be introduced to the concept of energy flow through organisms, and understand the basic processes of photosynthesis and...

An interactive module where students describe, compare, contrast and explain the relationship between photosynthesis and cellular respiration.

[Free Registration/Login may be required to access all resource tools.] The cell membrane is semi-permeable. Sometimes molecules need the help of special transport proteins or an input of energy to help them move across it. When an input...

Described is a simple low cost home-made device that converts the radio wave energy from a mobile phone signal into electricity to light an LED. No battery or complex circuitry is required. The device can form the basis of a range of...

[Free Registration/Login may be required to access all resource tools.] Looks at how atmospheric circulation cells affect the climate of regions.

[Free Registration/Login may be required to access all resource tools.] Describes how regional differences in solar radiation create global wind belts.

In this module students learn more about oxidation-reductions and how to balance these reactions and perform stoichiometric calculations on these specific reactions. Students also explore electrolysis, galvanic cells, reduction...

Kids learn about solar energy and how this renewable power can help the environment. Teach students about solar cells and using the sun for heat.

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 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...

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....

[Free Registration/Login may be required to access all resource tools.] How does the food you eat provide energy? Through the process of cellular respiration, the energy in food is changed into energy that can be used by the body's...

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.

Learn about the process of cellular respiration in the human body.

[Free Registration/Login may be required to access all resource tools.] Definition of cellular respiration and its overall chemical equation. The energy changes that occur during cellular respiration, including in photosynthesis.

[Free Registration/Login may be required to access all resource tools.] Sometimes cells need to obtain energy from sugar, but there is no oxygen present to complete cellular respiration. In this situation, cellular respiration can be...

Discover the five characteristics that all living things have in common.

[Free Registration/Login may be required to access all resource tools.] Why do you need air to live? Of course if you didn't breathe, you couldn't survive. You need the gas oxygen to perform cellular respiration to get energy from your...

Work samples, phenomena, assessment templates, and videos that directly address standard MS-LS1-7: food and chemical reactions.

[Free Registration/Login may be required to access all resource tools.] Definition of a biochemical reaction, the different types and the importance of enzymes in biochemical reactions.

Read about Hans Krebs' childhood and how it influenced his interest in science. Read about the importance of mentors in his life as he did research in chemistry.
