Acids & Bases: What's the Solution?

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...

Getting back to the beginning of the unit, learners use reactions with red cabbage juice to determine if solutions are acidic, neutral, or basic. This is a straightforward and classic investigation, but what you will appreciate is the...

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.

An acid/base indicator that's made of blended red cabbage and water is used to demonstrate the various reactions that an acid/base solution goes through when some carbon dioxide gas is added. The best way to add the carbon dioxide is to...

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...

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...

Learners 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 solution...

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...
