Brief, but brilliant, this little animation investigates the properties of fire. From its color and recipe, to the shape of a flame, find out what you always wanted to know about fire. This makes an enlightening addition to your physical...

In session one, demonstrate for your class how a flame eventually goes out when enclosed in a jar in order to teach that oxygen is required for combustion. In session two, class members then burn sugar in a spoon to observe how it...

The details of a combustion reaction are described in this detailed video. Fantastic graphics and narration are included.

Accomplished chemistry learners set up a calorimeter and measure the energy released by various alcohols: methanol, ethanol, and either propanol or butanol. Lab masters will first need to design their own tables for recording data....

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...

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 general...

Don't just use this as an extra credit assignment! The two scenarios on this handout give microbiology hopefuls an opportunity to practice critical-thinking skills. They apply their knowledge of cellular respiration and the products of...

In this observation worksheet, scientists observe a burning candle and answer eight post-lab questions. Topics include the phase changes occurring during the observations, the role each part of the candle plays in the chemical reaction,...

A variety of topics including reaction rates, combustion reactions, periodic trends, and ionization reactions are included in this exam. Test takers also practice calculating empirical and molecular formulas of compounds.

Ladies and gentlemen, start your engines! Explore the cumbustion reactions driving the world's automobiles and the chemical solutions used to keep their engines cool with this fun instructional video.

A teenaged Jack Spangler demonstrates how reducing air pressure in a bottle can pull a boiled egg inside. Then dad does a similar demonstration using liquid nitrogen to reduce the air pressure. Even though the result is the same, the...

What's a fire and how does it burn? The narrator in this video describes the details of how fire is created. It is a great video to show during your science lesson.

Instruct your chemistry stars on the five different classes of chemical reactions with text, computer animation, and narrative. This video is short and to the point. Embed it into your PowerPoint or SmartBoard presentation when teaching...

In this formulas and equations worksheet, chemistry apprentices write the chemical formulas given the names. They calculate percent composition, balance equations, and calculate the mass of a substance present in a fertilizer. This is a...

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...

For an introductory physical class, you can use these vivid activities to introduce learners to chemical reactions. Spontaneous combustion, melting and burning, tarnishing and rusting all are evidence that a chemical reaction has...

If you know how to employ the exothermic reaction between hydrogen gas and oxygen gas to make a miniature rocket, then this worksheet is a fabulous lab sheet for your chemistry charges. First, they observe a spark in pure oxygen and one...

This PowerPoint presentation is sure to support your lesson on chemical reactions. Colorful diagrams and pictures, solubility tables and rules, clever animations and diagrams make teaching these concepts a cinch! Your chemistry...

Future scientists are introduced to the chemical consequences of burning fossil fuels, learning that fossil fuel combustion leads to the formation of oxides of three nonmetals: carbon, nitrogen, and sulfur, all of which end up in the...

National Chemistry Olympiad tests are released after their use each year, since they cannot use them again for this event. The result: outstanding comprehensive assessment resources for general chemistry classes! This 2005 version covers...

In this chemical reactions learning exercise, 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.

In this reactions worksheet, young scholars complete the given reactions by writing the products. Students do examples of composition, decomposition, single replacement, double replacement, and combustion reactions. This worksheet has 54...

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 concepts to...
