Whether in the UK or the US, the mass of the copper in a copper alloy penny can be determined. If you are in the US, note that on the lab sheet, a penny is identified as a "1p piece." The penny is dissolved by young chemists in nitric...

How do scientists determine when a solution is fully saturated? Scholars address the topic as they observe patterns of precipitation in various concentrations of ions. Using a well plate, pipette, and common chemicals, they collect data...

In this chemistry review worksheet, students identify chemical changes, isotopes, ions, and chemical bonds. This worksheet has 32 multiple choice questions.

Using simple materials, an informative lesson demonstrates the Law of Conservation of Matter and explains how to balance chemical equations. Young chemists perform experiments, analyze reactions, and balance chemical equations...

The molecular properties of water are the focus of this chemistry-based assignment. Multiple-choice, true-or-false, matching, and fill-in-the-chart style questions query assignees about the forces that hold the water molecule together,...

Students study how to write chemical fomulas by reviewing the combinations atoms form into compounds. They write a procedure to test various substances and name the compounds and write formulas. As they construct models for formulas and...

In this chemical bonds instructional activity, learners review the different types of bonds, Lewis dot structures, ions, and molecule shapes. This instructional activity has 10 matching, 17 multiple choice, and 3 drawing questions.

Students engage in a lesson which includes flame tests and the construction of a simple diffraction spectrograph with which to measure sodium ion emissions. They use the Bragg equation to compute the wavelength of the line spectra produced.

In this solubility equilibria worksheet, students solve five problems. They calculate concentrations of ions at equilibrium, they determine the effects of adding compounds to a saturated solution and they determine if compounds are more...

In this acid and base activity, students use seven steps to calculate concentrations of ions in acidic and basic solutions. They also determine the type of acid or base.

In this pH worksheet, students answer ten questions about acids and bases as well as pH. They determine the pH given concentrations of ions in a solution. they also describe various types of acids and bases.

Into each life some rain must fall, but how can that change rocks? Young geologists' understanding of weathering and erosion increases throughout the activities. The lesson includes five short activities to be completed...

In this chemistry worksheet, students identify 3 different chemical compounds, 3 identify biochemical products, 4 identify terms, and 2 identify atomic symbols.

Students define the term acid rain, and the causes of acid rain. They locate regions where acid rain is most affected, and what can students deduce from maps of geology and soils in New York State. Students answer the questions why are...

Learners test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...

Students work together to test water samples for pollutants. They design data tables to collect and record their observations. They complete discussion questions to end the lesson.

In this chemistry worksheet, students write the balanced equation for the reaction and rearrange the potassium expression to solve for x. Then they determine how many grams of silver chromatic can dissolve in a specified amount of sodium...

In this solubility worksheet, learners calculate the final concentrations of the ions involved in a chemical mixture. Students calculate the solubility of different compounds. This worksheet has 13 problems to solve.

In this acid-base reaction learning exercise, students calculate the ion concentration and pH for 6 solutions, graph titration results for 11 reactions and use Henderson-Hasselbach equations for three problems.

In this acids and bases worksheet, high schoolers read about the differences between acids and bases and then complete a table comparing the characteristics of both. Then students determine if the given statements describe an acid, base,...

In this activity, learners review the definitions of acids, bases, and salts. They also describe the differences between acids and alkalis and define neutralization. This activity has two short answers and one problem to solve.

In this acids and bases worksheet, students determine the pH and pOH for a given solution. Students determine the conjugate acids for the given species. Students calculate which solution will have a higher pH. This worksheet has 16...
