For this percent of iron in lawnsand worksheet, learners perform a titration of lawnsand using potassium manganate(VII) solution and determine the number of moles of iron in the sample. Students use the number of moles to find the mass...

Students will review a semesters worth of material on this final chemistry review. Information ranges from naming isotopes to pH and molarity.

In this chemistry Olympiad worksheet, students solve sixty multiple choice questions on a variety of chemistry topics from finding molarity of solutions to calculating products of reactions. Students are given graphs, equations, reaction...

High schoolers are able to draw a diagram of the light reactions and briefly describe what is occurring throughout the process. They are able to explain where each reactant/product in the photosynthesis equation comes from/goes during...

In this acid-base worksheet, students write balanced chemical equations given the reactants for 18 reactions. If no reaction occurs, they write N.R. They also rank acids and bases in increasing order.

If you need a variety of questions for reactions and rate calculations, this resource is for you. Inspire your students to manipulate values and equations to fit the questions. The word problems are quite involved and require young...

We know about the light spectrum, the age spectrum, and sound spectrum, but do chemical reactions also occur on a spectrum? Young scientists experiment with partial reactions on a spectrum and observe the color changes. Then, they...

Starting with definitions and terms related to how electricity flows, these slides assist in understanding of displacement reactions. Some typical displacement reactions that occur with a flow of electricity through a solution are...

This review sheet will be very useful to test your pupils' understanding of battery structure and redox reactions.  The questions ask for equations to be balanced and for the traditional equipment setups to be drawn and labeled....

Here is a laboratory exercise in which chemistry masters conduct an oxidation reaction to change ethanol into ethanal. They compare the original alcohol to the resulting aldehyde by forming a precipitate. This activity is aimed at...

It's the law—every action requires a reaction, no matter how small. Pupils experience two demonstrations of Newton's third law of motion as it relates to thrust in the 10th segment of a 22-part unit on flight. Using their mathematical...

Scientific studies show the older we get, the more acidic we become. The activity extensively teaches high schoolers about acids and bases. By the end of the 14th installment of 36, they can define and explain three concepts of...

These summary slides will be helpful to your class while studying the reactions of bases. The basic reasons for writing the equations of ionization are explained, and some details about the formulas used to balance equations are given.

Thirty-seven slides thoroughly shed light upon the four classes of matter: elements, compounds, mixtures, and solutions. Also covered are chemical symbols, molecules, and chemical equations. The colors and fonts chosen for the...

A single page provides you with lecture notes for your lesson on hydrolysis. Introduce your chemistry class to Bronsted-Lowry theory by explaining the hydrolysis of acidic cations and basic anions. Show them how the resulting pH can be...

Chemistry and earth science meet in a instructional activity on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They...

Lead your class in this exciting activity to learn more about motion and its importance. Pupils learn about a centripetal and why it is required to maintain a constant speed in a circulating moving mass. They apply the equation for...

Four balanced chemical equations are presented for your pupils to analyze. They identify limiting reagents and use dimensional analysis to compute products. This practical worksheet is one that you will want to keep in your repertoire to...

Students determine the rate law for a chemical reaction. They use graphical techniques in the analysis of experimental data.

High schoolers research and evaluate chemical reaction demonstrations that are found on the web. they work in small groups to choose a demonstration that fits a particular category of reaction and then perform the demonstration for the...

In this stoichiometry worksheet, learners calculate balance the chemical equations and then calculate the moles needed to complete or activate the chemical reaction. Students also calculate the volume or grams needed for each chemical...

Young scholars conduct an experiment in which they react sodium bicarbonate with hydrochloric acid to determine the molar ration between the two reactants. Students must write correct formula and a balanced chemical equation and explain...

Students conduct an experiment in which a solution of copper(II) sulfate is added to iron filings. They write and balance the equation for the reaction that occurs and calculate the amount of iron that reacted and the percent yield of...
