Students calculate stoichiometrically the amount of carbon dioxide that would be emitted from burning a mole of varios alkanes that comprise fossile fuels. If the energy released from burning a mole of these alkanes is known, then the...

In this electrochemistry worksheet, students solve a variety of problems including identifying parts of oxidation and reduction reactions, writing balanced equations for galvanic cells, determining free energy and equilibrium constants...

High schoolers observe how a cell uses an enzyme to rid itself of a poisonous substance by experimenting with hydrogen peroxide, potatoes, liver and carrots. They record the temperature and changes of the hydrogen peroxide as other...

Students listen to an explanation of yeast cells and how they effect bread and beer. They discuss the ways alcohol affects the human body and participate in an indirect observation about cell respiration in yeast-molasses cultures.

Seventh graders explain the mechanism of digestion. In this biology lesson plan, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

In this diffusion through a membrane worksheet, students fill in the blanks to complete 27 statements about cell membranes, the movement of molecules across the cell membrane, concentration gradients and diffusion.

Middle schoolers build an apparatus to look at how yeast cells grow by converting food to energy. They observe yeast both with and without food and see how yeast produces carbon dioxide.

In this electrochemistry worksheet, students solve 9 problems such as identifying masses of metals produced at cathodes, determining the potential of a cell's electrode and writing cell reactions along with their potential.

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

In this living environment worksheet, students answer a variety of questions about living organisms, the processes they go through to make food and break down food, absorb nutrients, and release toxins. They explain homeostasis, they...

Seventh graders identify the different parts and functions of the cell. In this biology instructional activity, 7th graders make a labelled diagram of either a plant or animal cell. They write a story about it.

Students compare and contrast cellular respiration in yeast and plant and animal cells. After discovering the role of yeast in making beer and bread, they describe the short and long term effects of alcohol on the nervous and digestive...

Following detailed directions, teams collect the voltage and current outputs of a photovoltaic cell by adjusting the resistance. Using the collected data, they determine the highest power output. Implications for weather and a large...

Students explore how rechargeable batteries work by conducting a series of experiments. In this physics instructional activity, students discuss the benefits of using rechargeable batteries over disposable ones. They build their own...

Young scholars investigate the rate of photosynthesis using elodea leaves. In this photosynthesis lesson plan, students place elodea in a test tube filled with water. They include baking soda and place the test tube under a lamp. Young...

This exam touches upon every topic within the typical first year biology course.. A broad variety of question styles give high schoolers every opportunity to show what they know. Why start from scratch when a comprehensive final exam is...

The National Chemistry Olympiad exams are comprehensive tests covering an entire  year of chemistry concepts. You can use them as practice for competing in the challenge, or simply as a review, or as an actual final exam for your...

The 2006 version of the Regents High School Exam is just as thorough as the rest of them! Assess chemistry learners on an entire year's curriculum when they take this thirteen page test. 

In this biology activity, students complete a crossword puzzle with 17 questions about the processes involved in cellular respiration.

Seventh graders look up pictures of viruses or pictures of models of viruses. Using pipe cleaners, beads, Styrofoam or other available materials make models of these shapes. They then observe a demonstration to show the effect of Tobacco...

Students examine how fuel cells and combustion engines work. Using the internet, they research the positives and negatives of the various energy sources. In groups, they complete an experiment with a working fuel cell model and take a...

Students utilize Internet resources to uncover the pros and cons of two topics in alternative energy technology: photovoltaics and fuel cells. Students analyze the structure and function of each system to make observations about the...

Seventh graders use technology to review cell structure and function. In this cells less, 7th graders review the parts and functions of a cell, and use photography/video and PowerPoint to enhance their explorations.

Seventh graders explore the cell cycle. They view pictures of different stages of mitosis and explain why cells reproduce. They identify the five phases of mitosis: interphase, prophase, metaphase, anaphase, and telophase.
