Seventh graders investigate acids and bases. In this acids and bases lesson plan, 7th graders use household items such as coffee, lemons and soap to define acids and bases. They observe a demonstration to show how indicators determine if...

In this pH worksheet, students are given information and directions as to how to calculate the pH of solutions. They use their calculators to find the pH of given solutions and apply what they learned about identifying acids and bases.

In this acids and bases worksheet, learners 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...

Young scholars investigate the strength of acids and bases experimentally. They answer the question, "How can pH be used to determine possible product tampering?" by testing acids and bases with litmus paper.

Students investigate foods that are indicators, and acids and bases. In this food chemistry lesson plan, students test household products with litmus paper and with food indicators. They use blackberry, onion and red cabbage indicators...

Eighth graders explain the difference between acids, bases and neutral solutions. For this chemistry lesson, 8th graders describe the properties of each. They determine the pH of an unknown solution using the indicator paper and pH scale.

In this water equilibria worksheet, students calculate the pH of solutions, they fill in a table with the type of acid or base given a compound and it's concentration and they calculate approximate solubilities for salts.

In this acid and base instructional activity, students use cabbage juice as an indicator to test the pH of various solutions. Students complete a table with the solution name, the color red and blue litmus paper turns, the color the...

In this salts and buffers worksheet, students answer five questions about the acids and bases that form salts as well as the equations for a buffer system.

In this chemistry worksheet, students answer short answer and true and false questions about acids, bases, atoms, elements, and more. Students complete 20 questions.

Students observe a demonstration in which a bottle containing a colorless solution is mixed, turns blue, then becomes colorless again. They record observations, form and discuss hypotheses, and draw a conclusion based on the evidence.

Students examine the observed world, molecular world, and the symbolic world of chemistry. They observe a demonstration of the conductivity of solutions, describe the properties of acids and bases, and predict the outcome of solution...

Students investigate pH levels in bodies of water and experiment with acid/base reactions. In this water and pH lesson, students observe changes in pH levels of a sample solution and observe a Bronsted-Lowry reaction. Students...

Students observe an electrolytic titration using a conductivity tester. In this titration lesson, students observe a solution of acid conducting electricity using the conductivity apparatus. They observe the acid solution being titrated...

In this problem solving worksheet, students calculate the base to 8 specific numbers. Students solve 3 base addition problems and draw a picture to illustrate each one.

In this base five worksheet, students complete a base five multiplication table and a base five addition table. Tables contain the first nine digits in base five (1-14). This two page worksheet contains 162 problems.

In this exponent worksheet, learners solve exponent problems containing positive and negative bases.  They multiply integers.  This four-page worksheet contains 27 problems.  Answers are provided on the last page.

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...

The first two pages provide a chart to complete with results of a lab test using different solutions and indicators. The data analysis questions will help your students understand the concentrations of the solutions and how they affect...

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...

Sure, your learners know water is made up of two molecules, but watching them separate helps the class see the construction like never before. This resource provides directions on how to build a simple electrolysis device using a...
