For this pH worksheet, high schoolers determine how indicators work and what the pH scale is used for. Students learn what happens when non-metals burn in air and metal oxides dissolve in water. This worksheet has 10 problems to solve.

Eighth graders study the concepts of acids, bases, salts and neutralization. They discuss steam adoption program, acid rain and other ecological implications. They use indicators to obtain pH values of household chemicals and to...

Students conduct a pH probe of various household products including both bases and acids. In groups, they use litmus paper to test such liquids as amonia, vinegar, and detergent to discover which are acids and which are bases. Finally,...

Young scholars recognize and use chemical indicators in the lab, recognize the need for safety while doing chemical experiments and understand the need for following precise directions.

For this buffer solution worksheet, high schoolers experiment with the addition of different solutions to a buffer solution and observe the changes in pH using a pH probe. Students describe the differences between adding pure water and...

Ninth graders complete an experiment to determine the pH values of a variety of common household substances. They use red cabbage to find the indicator colors of the pH range. They complete a data table that includes a prediction and...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Upcoming chemists use chemical reactions to determine relative pH in two different acids. This is a terrific lesson for middle schoolers that can stand alone as a practice in precision and lab skills, or as part of the unit on chemical...

High schoolers investigate the pH of solutions and they learn how to use different types of indicators. In this pH lesson plan, students test various solutions with pH paper and determine if they are acidic, basic or neutral. They also...

Middle schoolers test various liquids and identify as acids or bases. In this chemistry and pH instructional activity, the students use purple cabbage indicator to test a variety of teacher-provided substances, then bring in liquids from...

Seventh graders explore how milk spoils over time. In this biology lesson plan, 7th graders discover how pH changes as microorganisms enter the food and multiply. They explain the benefits of pasteurization process.

In this acids and bases worksheet, students identify the strengths of acids and  bases and indicate the concentration of hydronium and hydroxide ions. They determine if given chemical formulas are acids or bases, they find...

In this environmental lesson young scholars complete a series of multiple choice and short answer questions on animal populations, cell structure and chromosomes.

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Tenth graders distinguish between acids and bases. In this pH instructional activity, 10th graders view a PowerPoint and discuss the characteristics of an acid and a base. They investigate natural substances to determine the pH level of...

Learners experiment to determine the positive and negative impacts of human activities on environmental change. They examine how physical and biological processes such as decomposition affect soil characteristics while looking at the pH...

Young scholars study descriptions of indicators and the way they are used to identify acids and bases. They use this information to determine if unknown solutions are acids or bases.

Create a little scientific magic within your classroom! Learners mix powders and liquids and identify chemical reactions. Based on the reactions, individuals determine the identity of various powders.

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.

Students try to cure an upset stomach. In this acids and bases in the body lesson plan, students create a upset stomach with a vinegar and water solution, then use antacids and home remedies to attempt to restore pH balance to the mixture.

Students test pH of water before and after it travels through different substrates (igneous pebbles and limestone) to detemine how soluble materials can affect groundwater. They answer questions such as: What happended to the pH of the...

You won't get a stomachache doing an investigative experiment. Pupils simulate the effect of antacids on stomach acid. Obviously, they won't be using real stomach acid; diluted hydrochloric acid serves this purpose.

How does temperature affect lipase activity? Young scholars conduct an experiment to collect data on the interaction of lipase at different temperatures. They add lipase to a solution of milk, sodium carbonate, and phenolphthalein and...

If you don't want to drink red cabbage juice, here's another use for it—a decoder! Using vinegar and ammonia-based window cleaning liquids as invisible inks, scholars create designs in the second lesson of the series. Red cabbage juice...
