Fourth graders examine aquatic orgnaisms and how enviromental chages affect them. This factors include: temperature, Ph, oxygen, nutrients, and pollutants. They also explore habitat quality (erosion). Students compile data and create...

Students collect samples of rainfall, cloud condensation, and water that trickles through the soil. These samples are tested for pH, conductivity, and the presence of sulfates, nitrates, calcium, and magnesium.

Students are introduced to the concept of acids and bases and arouse curiosity about acids and bases in daily life. They are introduced to the measurement of soil pH. Pupils are introduced to the effect of soil pH on nutrient cycling...

A series of 25 multiple choice questions is presented to chemistry learners to review properties of acids and bases. A page of notes precedes the questions and contains information about the Arrhenius and Bronsted-Lowry definitions,...

This PowerPoint progresses slide-by-slide through all the facts you would want to deliver about acids, alkalis, salts, and the related lab tests. Each slide has one or two facts about a physical or chemical property or behavior. The...

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 experiment with household solutions and classify them as a base or acid.  In this exploratory lesson students complete a lab where they test products to see if they are an acid or a base. 

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,...

Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

In this acids, bases and buffers worksheet, students define terms, solve problems such as calculating the pH of solutions and the molarity of solutions and they write balanced equations of neutralization reactions.

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...

In this chemistry lab, students determine whether or not their saliva is acidic, basic, or neutral. After completing their test, they answer 6 analysis questions.

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...

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...

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...

Students combine different materials to create chemical reactions. For this chemical reaction lesson plan, students will combine different materials to create chemical reactions and define these results as acids or bases. They will 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...

For this acid and base worksheet, students calculate the pH of solutions, sketch a titration curve, write equations used to determine the pH of solutions and determine the location on a titration curve of a given molar solution.

In this acid and base learning exercise, students answer 7 questions about acidic and basic solutions such as the color each turns litmus paper, the pH values, the balanced equations for neutralization reactions and their pH and...

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 weak acid and base learning exercise, students find the pH of solutions given the equilibrium constants for each of the weak acids and weak bases.

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...
