What is the difference between chemistry and green chemistry? The first lesson plan of the 24-part green chemistry series introduces scholars to its 12 principles. The tendency is toward nontoxic materials and sustainability.

Colorful chromium is captivating! Science sleuths solve a series of puzzles using an interactive resource. Individuals relate the oxidation states of chromium to the colors produced when the compound is placed in acidic or basic solutions.

More than 80,000 scholars earned college credit for Chemistry with the AP exam in 2015. The College Board released the free-response questions covering topics, including moles, that often confuse scholars. They also released example...

Don't waste all that carbon dioxide. Scholars first produce carbon dioxide by mixing baking soda and vinegar. They measure the masses of the reactants and products to verify the law of conservation of mass. As a culminating activity,...

The cycle of energy is important to many different systems on Earth. Scholars use questioning and observation to investigate the differences between renewable and non-renewable resources and how they relate to global changes. They...

Bring out some bubbly! Individuals perform the classic baking soda and vinegar experiment with a twist. Learners add a drop of dish detergent to make the bubbles last longer. They vary the amount of baking soda and vinegar in an effort...

Things are getting a little slippery in an inquiry-based lesson studying precipitates. Learners use soap and Alka-Seltzer tablets to create different mixtures with water. They then study the properties of the mixtures including their...

Finally, a photosynthesis activity that outshines the rest! Young biologists perform an experiment that allows them to observe photosynthesis through the production of oxygen. The lesson, part of the K20 series, also includes a study of...

In this solutions worksheet, students balance chemical equations, classify reactions by the type of reaction it represents, and review the solubility rules. Students practice working out double displacement, neutralization, and dilution...

Students investigate activation energy through endothermic and exothermic reactions. In this activation energy lesson plan, students conduct 2 experiments, one is an endothermic reaction and the other is an exothermic reaction. Students...

High schoolers define several vocabulary terms related to chemicals and toxicology. Students calculate chemical concentrations in water and explain the toxicological principles that govern safety of substances. High schoolers conduct an...

Students connect rock and mineral formation with the changes rocks and minerals undergo at the earth's surface. They observe changes produced by weathering and relating these observations to chemical processes such as oxidation,...

Students investigate energy. In this Physics instructional activity, students explore different sources of energy: heat, nuclear, and chemical. Students sing an electricity song.

For this gas law worksheet, students review the Idea Gas Law equation and practice applying the equation to chemical reactions. Students write the balanced reaction, determine the limiting reagent, moles produced, and volume of gas...

In this ester worksheet, students mix organic acids with alcohols to produced esters and identify the products by the chemical reaction and the scent given off after the reaction occurs.

In this general chemistry worksheet students complete a series of multiple choice and short answer questions on elements, chemical properties and various chemical reactions.

Learners find moles and molecules used when a candle burns. In this moles and molecules lesson plan, students calculate the initial mass of a candle and the mass of a candle after it burns for 3 minutes. They calculate the mass lost when...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

In this ketones and aldehydes worksheet, students name four compounds given their structures, they write the formulas for four compounds, they draw the structures given four compound names and they complete five chemical reactions.

In this alkenes and alkynes worksheet, students name six structures using the IUPAC naming systems and they draw three organic molecules. They also answer a question about a chemical reaction using the Markovnikov rule.

In this stoichiometry worksheet, students are given four chemical reactions and they find quantities of products made, limiting reactants, excess reactants, and percent yield of products.

In this stoichiometry worksheet, students use four balanced equations to calculate mole of products made, moles of reactants needed for chemical reactions to proceed and mass of reactants needed to produce products.
