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...

High schoolers discuss what the m in E=mc2 represent. They relate that mass in a chemical reaction is always conserved. Students convey that atoms rearrange themselves in chemical reactions to form different molecules and compounds.

Students predict the product of chemical reaction using the solubility rules. In this chemistry instructional activity, students balance ionic equation. They perform a lab to check if their predicted products are correct.

Students observe the chemical change that occurs when sodium iodide is dropped into a flask containing 30% hydrogen peroxide. They discuss how this exothermic reaction occurred as they study the chemical equation involved in the reaction.

Students use indicator paper to determine if substances are acidic, basic, or neutral. They test for Ph levels in them. They investigate the effect of oxygen on darkening fruit cut and exposed to the air. They observe vitamin C as an...

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...

Students investigate plant pigments in fruits and vegetables. For this plant pigments lesson plan, students observe the effects of pH changes on chlorophyll in one demonstration and they observe the effects pH changes on flavonoids in...

In this chemistry worksheet, students write in the correct equations in accordance to solving the word problems. The answers are on page 2.

In this thermochemistry instructional activity, learners calculate the enthalpy of vaporization as well as the write the thermochemical expression for the production of the chemical reaction.

Students define what a redox reaction is. In this chemistry lesson, students electroplate some wires in the lab. They research the application of electroplating in the real world.

In this water worksheet, students compare and contrast elements and compounds. Students define chemical symbols, chemical formulas, and chemical properties. This worksheet has 19 short answer questions.

Students recognize epoxy glue formation as two part polymerization (usually the curing agents act as co-monomers). They monitor the reaction by the changes in viscosity of the reacting mass, the temperature rise and fall, and the...

Although their name makes them sound dangerous or toxic, carboxylic acids are found throughout nature in things such as citric acid, vinegar, and even in your DNA. Through detailed readings, discussions, and answering questions...

Students design a battery, identify and label the anode, cathode, electron flow, ion flow, oxidation & reduction reactions, chemicals used including the location of each;and distinguish between anode materials with regard to energy...

A review of a full unit on energy and matter, this slide show starts with basic definitions of states of matter and their mass. It then develops the ideas of the forces that that matter can exert. Details about bonding within matter and...

Challenge young scientists to design their own experimental procedures. They write the procedure for properly preparing two grams of a water-insoluble ionic salt. To finish, they perform the experiment and collect data to prove their...

In chemistry, organic means something contains a carbon base. A helpful presentation starts by defining macromolecules as large organic carbon molecules. Scholars answer questions about each topic on the associated worksheet. It covers...

Students investigate the chemistry of coal. This lesson serves as a review of conservation of mass, simple reactions and equation balancing. During the lesson, students research chemical components of coal, as well as environmental...

Students research chemical components of coal, as well as environmental health impacts of mining and burning coal. They discuss conservation of mass as it relates to combustion of organic compounds.

In this chemistry overview worksheet, students review stoichiometry, states of matter, thermochemistry, gas laws, chemical bonding, molarity, chemical equilibria, and kinetics. This worksheet has 41 problems to solve.

In this chemistry worksheet, students complete 15 short answer questions and problems on empirical and molecular formula, naming and writing chemical formula of compounds.

Sixth graders observe the physical and chemical change that can occur in an acid and a base. In this acids and bases lesson plan, 6th graders use cabbage juice to identify, compare, and contrast acids and bases.

In this atoms learning exercise, students calculate the number of moles, molarity, grams, or formula units for 20 different problems.
