Radioactive decay, pH, properties of elements, organic compounds, and stoichiometry are all touched upon through this practice chemistry exam. It always helps learners to take a practice test in preparation for the actual exam. This...

In this acid and base activity, students review the characteristics of acids and bases, how to calculate pH of a solution, and define a buffered solution. This activity has 16 multiple choice questions and 3 problems to solve.

Students explain the Chatelier's Principle. For this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

In this weak acid and base worksheet, students find the pH of solutions given the equilibrium constants for each of the weak acids and weak bases.

In this acids and bases activity, students answer 20 questions about acids, bases, neutralization reactions, buffers and molar solutions.

For this equilibrium worksheet, students solve nine problems related to acids, bases, buffers, ionization and calculations of pH.

Scholars learn about kinetics and buffers as they use qualitative and quantitative methods to understand enzyme rates and buffer capacity. The application of Beer's Law and spectrophotometry solidifies pupils' knowledge in the first of...

How does carbon dioxide affect the world's oceans? The final installment in a series of six lessons has pupils research ocean acidification, then conduct an experiment to witness the delicate balance that exists in our seas. Materials...

Students study La Chatelier's principle and identify how carbon dioxide may affect pH.  In this coral activity students complete a worksheet on pH and observe a lab.

For 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...

In this equilibrium worksheet, students answer thirty multiple choice problems including topics such as pH, analyzing titration curves, calculating molar concentrations and working with equilibrium constants.

In this acids and bases worksheet, students complete 32 fill in the blank and short answer questions on acidity or alkalinity. They color molecular diagram according to the key.

Simulated acid rain, a dilute sulfuric acid solution, needs to be prepared for this demonstration. After a condensed lecture on acid rain, you will apply the solution to a sample of granite and a sample of limestone. Your young...

In this chemistry worksheet, students take an exam that presents the concept of maintaining the ph balance. This can become a formal assessment.

You matter—unless you multiply yourself by the speed of light squared, then you energy! Scholars learn about matter, energy, the elements and so much more using an informative presentation. Completing the included worksheet creates a...

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

Students add the acid and base drop wise as the protein precipitates. If either are added too rapidly, students may miss detail or the protein may not have sufficient time to renature. Casein does not buffer the solution well when it is...

High schoolers study the pH scale and sources of acid precipitation.  In this acid rain lesson students complete a lab on acid rain then complete a handout.

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Use indirect measurements to monitor metabolic activity in plant cells. Scholars understand that cells with a higher metabolic rate have a higher concentration of catalase enzyme. They use this information to compare metabolic rates of...

In this health learning exercise, students identify various infectious diseases and explore the available options for stopping or preventing the spread of disease. They participate in a simulation experiment on how to measure and...

Tenth graders explore DNA using online tutorial. They perform their own DNA extraction from a clove of garlic and identify the key components of DNA.
