The pH scale

Students explore acids, bases, and indicators. They use turmeric solution, phenolphthalein, and goldenrod paper to determine the acidity and basicity of a variety of common household substances. A worksheet is included to record test...

Fifth graders perform tests to identify acids and bases.  In this chemistry lesson, 5th graders identify common household substances as acids or bases using cabbage juice indicator strips.

In this acid and base chemistry worksheet, students solve 25 clues in a crossword puzzle based on the pH of common household solutions and common names of chemical compounds.

In this acids and bases worksheet, students are given a list of characteristics of either acids, bases or both acids and bases. They use the terms to complete a Venn diagram about acids and bases.

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Middle schoolers prepare a test solution whose color changes when an acid or a base is added. They determine whether various household substances are acids or bases and look for patterns in the results. Students determine how their test...

Watch as acids and bases put smiles on their faces. Young chemists learn the concept of acid-base titration firsthand in a microscale experiment. Working groups collaborate, titrate, then use their data to determine the concentration of...

Looking for a comprehensive plan for teaching acid-base chemistry? Science scholars discover acid-base interactions through a thoughtfully written unit. The resource is divided into paced activities and individual work designed to...

Students investigate acids, bases,and pH. They test the acidity and basicity of various household items using litmus paper. Using their results, they rank the substances according to pH and identify the contributing chemical on the label.

Acid rain, and how it affects the environment, is the focus of this Earth science lesson. During the study, learners evaluate measures to reduce acid rain, and design an investigation to demonstrate the conection between a hypothesis and...
