Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

A table of the physical properties of metals and non-metals opens this high-school chemistry handout. Also covered are the chemical properties of metals and non-metals, reactivity, and fossil fuels. There are no specific questions to...

Do you have mole problems? If so, call Avogadro at 602-2140. The lesson starts with pupils working independently to solve for molar mass of ionic compounds. Then they learn to solve for percent composition and later perform an...

Why was Sir Newton so important to the field of science? Pupils discuss his contributions, specifically his Third Law, as they learn about gravity and the center of mass. They work multiple problems to ensure their understanding and...

Students investigate polynomials. In this algebra instructional activity, students solve problems dealing with multiplication of polynomials by using the distributive property and the FOIL method. Students...

A cookie recipe is displayed as an example of proportional relationships, a clever way to introduce your chemists to stoichiometry! The steps of stoichiometry are listed, molar volume is explained, and then several stoichiometry problems...

Experiment with mass and density as scholars figure out what makes things float or sink. First, they watch a podcast introducing these concepts. Be sure to use the comprehension question to test their understanding. Young scientists...

Introduction your class to famous astronomers with a presentation that also covers Newton's Laws of Gravitation, Kepler's Laws of Planetary Motion, both uniform and nonuniform gravitational fields, and how to calculate the gravitational...

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Junior chemists discover how to calculate excess reactants, handle limiting reactants, and determine percent yield. After background information is provided, step-by-step examples are solved. You can use this detailed slide show to teach...

What do animated videos have to do with mathematics? Using operations of complex numbers and their representations on the complex plane, high schoolers observe how mathematics could be used to move animations. The lesson...

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Of course, there might be a correlation! Young mathematicians investigate several different data sets, create scatter plots, and determine any correlation. They consider whether a causation exists between any of the variables in question.

In this titration learning exercise, students determine the number of moles of an ion present in given solutions. Students calculate the relative formula mass and the concentrations of ions for solutions. This learning exercise has seven...

In this equilibria worksheet, high schoolers answer 5 multi-step questions which pertain to equilibrium expressions and concentrations.

This four-page handout would work great as a reading guide or note-taking resource for teens learning about ATP, photosynthesis, the key scientists in the realm of photosynthesis, and more. It is designed to accompany a certain textbook,...

How are kids supposed to know what to study for that cellular respiration test? With a study guide or reading guide like the one found here. With three pages of questions important to the understanding of respiration and the processes...

Students design and construct a paper rocket that can be launched with a drinking straw. They participate in a lecture and read an article about rocketry and how Newton's Third Law applies to rocket launches. Each student constructs...

In this equilibrium worksheet, students calculate the equilibrium concentrations for given compounds. This worksheet has four problems to solve.

AP biologists aspire to respire with this worksheet. In it, they write short answers to 26 questions about cellular respiration. Topics addressed include the Kreb's cycle, fermentation, and more. Written as a chapter reading...
