Learners determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...

Students illustrate the molecular nature of matter and show that chemical change involves alteration of molecules.

For this electrochemistry worksheet, students balance 10 chemical equations and complete 28 additional questions about electrochemical cells.

In this reactions worksheet, students learn how to solve stoichiometric problems based on the mole ratios of a balanced equation. Then students complete 7 problems.

In this thermochemical equations worksheet, students read about and practice writing equations for thermochemical reactions. They also sketch enthalpy diagrams of the equations if applicable.

In this chemical equations worksheet, high schoolers are given 37 word equations and they complete each by filling in the product or reactant that is missing using words.

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

In this oxidation-reduction reactions worksheet, high schoolers read about reactions where elements gain and lose electrons. When elements gain electrons they are reduced and when the lose electrons the elements are oxidized. They are...

Students investigate oxidation and reduction reactions. For this oxidation and reduction lesson plan, students construct an electroplating device and perform an oxidation/ reduction reaction. Students describe the chemical changes that...

In this limestone reactions worksheet, students read about the various types of limestone reactions and complete a diagram of deposits in a cave. They answer two questions about limestone reactions.

For this formula for magnesium oxide worksheet, students perform an oxidation reaction between magnesium and the oxygen in the air to produce magnesium oxide. Using the known masses of the magnesium and the end product, students find the...

In this neutralization reaction learning exercise, students read about how neutralization reactions are double replacement reactions in water. They complete five questions about neutralization reactions including completing five...

Seventh graders investigate the fermentation process and the chemical changes that take place. In this fermentation lesson plan, 7th graders mix extracted apple juice with yeast and sugar water and observe the reaction over the course of...

Students investigate which metal is best to use as storage material in hydrogen cars. In this chemistry lesson, students differentiate endothermic and exothermic reactions. They write a reflection paragraph about what they learned in the...

In this chemistry interactive quiz, students answer 15 multiple choice questions on chemical bonding, enthalpy and Lewis structures.

In this organic reactions worksheet, students are given descriptions of the seven types of reaction of organic compounds. They then answer six questions about these reactions.

In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...

In this stoichiometry worksheet, students interpret a chemical equation, determine number of moles produced or mass of product, and solve for the limiting reactant for reactions. This worksheet has 25 problems to solve.

Students create a battery using pennies. In this galvanic reactions lesson plan, students use pennies, a washer, salt water, wires, tape and a paper towel to create a battery. They use a voltmeter to record the voltage in their battery...

Students quantify the relationship between temperature, energy and heat and define an endothermic reaction. They measure the energy change caused by dissolving one mole of ammonium nitrate in water.

Students identify the factors that influence reaction rates. For this chemistry lesson, students design an experiment to test one factor they identified. They perform the experiment and share the results to the entire class.

In this limestone worksheet, students name three sources of calcium carbonate, write the chemical formula, and determine the three elements found in calcium carbonate. This worksheet has 7 short answer and 3 problems to solve.

Eighth graders distinguish between physical and chemical change. In this chemistry lesson plan, 8th graders observe a series of demonstrations showing physical and chemical changes. They identify the signs that a chemical reaction took...
