As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth of...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

High schoolers conduct an experiment using the reaction of hydrogen and oxygen. After pairs balance the chemical equation for making water, they mix different ratios of hydrogen and oxygen in a chemical reaction. Classmates...

Here is a short, but well-rounded review of redox reactions. Chemistry apprentices identify the type of reaction, write half-reaction equations, balance equations, and assign oxidation numbers. Being brief, this would make a purposeful...

If you need a homework assignment for your chemistry class, add this one to the possibilities. This assignment is composed of six questions including the identification of oxidizing and reducing agents, recognizing different redox...

Use demonstrations to enlighten learners on oxygen's role in combustion. Use potatoes and hydrogen peroxide to increase oxygen concentration in a jar, then stick a glowing splint and a burning wad of steel wool into the newly formed...

In this chemical reactions activity, students are given the reactants of equations and must complete each equation by writing the products and balancing the equation. They must also identify the type of reaction.

This presentation is about air. What makes it unique is that, in addition to simply providing information about the components of air and the action of air pressure, it  includes a series of four experiments that bring these...

As the title suggests, this is a simply summary of fossil fuels. There are no questions to answer or problems to solve, just notes about fossil fuels. The notes cover how fossil fuels are formed, how we extract it, what humans use it...

A list of word reactions are given. Your class should write balanced equations, along with giving the reaction type and physical states.

In this history of heating worksheet, students read about the different ways of heating rooms over time. They answer three critical thinking questions about conduction, convection and heating.

For this pressure worksheet, students create an environment in a bottle to produce a cloud using a lit match and water. They study the effects of changing the pressure inside the bottle on the environment within the jug.

Learners discuss the benefits and problems associated with fire. They discuss the role that fire plays in maintaining healthy ecosystems. Students brainstorm ways that fire can be harmful, such as damaging homes, communities, and...

A pumpkin and a candle are all you need to help teach your students about what keep a flame going, and what factors lead to its going out. A lot of rich discussion should result from this fun activity. A great addition to a science...

Young scholars design parts for a scale-model, internal combustion engine using software.  In this engine lesson plan students work in groups to assemble an internal combustion engine. 

Students investigate the art and science of pyrotechnics.  In this chemistry and computer lesson, students learn about the chemical basis of fire and structure of fireworks.  Students then apply their knowledge in...

In this alkane reactions worksheet, students define combustion and write the balanced equations for the combustion reactions. Students write the structural formulas of the products including all possible isomers and their percent...

In this chemistry worksheet, students determine the number of water molecules is a given volume of water. Students determine the empirical formula for given compounds from the percentage mass of elements. This worksheet has 20 problems...

In this chemistry learning exercise, students write the balanced equation for the formation of one mole of fat from its elements under standard conditions. Then they write the balanced equation of the combustion of this fat. Students use...

In this balancing equations worksheet, students determine the type of reaction and write the balanced equation. Students read the word description and write the symbol of each element using the periodic table.

Students investigate coal samples and analyze its drying loss under controlled conditions. They establish the loss in mass of a sample when heated under controlled conditions of temperature.

In this lesson plan, students learn about the components of air and the chemical reactions that release carbon dioxide into the atmosphere and explore the connection between carbon dioxide, climate change, and environmental health.
