Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

Acid-base indicators are an essential part of any chemistry classroom. Individuals explore the color-changing feature of the important indicators in a vibrant hands-on activity. Using serial dilution, learners create solutions ranging...

How does a change in pH affect the ocean ecosystem? Scholars explore the idea by making an acid-base indicator in part seven of the 10-installment Discover Your Changing World series. First, they explore impacts of carbon dioxide in...

Students study the differences between an acid and a base.  In this pH lesson students view a demonstration then test chemicals in groups.

Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

How do people determine if something is acidic or basic? Learners make their own acid-base indicators using red cabbage and then determine the acidity and alkalinity of different substances. First, they test substances of known pH and...

Students explore the use of acid and base pH indicators. The teacher saturates an indicator sponge with congo red solution. Afterwards, the sponge is placed in a blue base solution. Students observe that the blue sponge actually turns...

Pupils puzzled over pH? Incorporate an interactive resource that teaches through games! Chemistry scholars use reasoning to solve puzzles that focus on determining the pH based upon hydrogen ion concentration.

Feeling a little neutral about your pH and pOH teaching strategy? Perk it up with engaging puzzles! Young scientists relate ion concentration to pH and pOH, as well as the dissociation constant for water. The resource is available as an...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

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...

The University of the State of New York has designed a series of exams to be given to high schoolers. This chemistry exam is one of the most comprehensive and well-written that you will ever find. It consists of 84 questions in a variety...

Fourth graders compare the color of cabbage water when acids and bases are mixed in. For this acids and bases lesson plan, 4th graders use cabbage water and mix in acids and bases that the teacher prepares before hand. They observe the...

In this pH instructional activity, learners describe acids and alkalis. They also determine whether substances are strongly acidic or alkaline. To determine the pH of given substances, learners use the color of universal indicator paper....

In this pH worksheet, students experiment with dilutions of acidic solutions to test for the pH using cabbage as an indicator. They then test a variety of substances for pH. On day two of the lab, they test conductivity of solutions and...

Students identify the differences between acids and bases. In this acids and bases lesson plan, students identify and distinguish between acids and bases. They use household products to test the ph levels. They test the ph levels by...

Young scholars explore what chemical indicators are and use pH paper to determine if something is alkaline or basic.  In this pH lesson students manufacture their own soap.

Students set up and run the experiments they designed in the lesson, 'Population Growth in Yeasts,' using simple yeast-molasses cultures in test tubes. They demonstrate understanding that several environmental factors can contribute to...

As to be expected from the American Chemical Society Olympiad Examinations Task Force, this 60-question test tops the charts in terms of excellence. It consists entirely of multiple choice questions designed to assess a year's worth 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...

After demonstrating the use of cabbage juice as a pH indicator, have your class experiment with their own breath, exhaling into the indicator, to show that carbon dioxide is acidic. As learners work, they also watch a video about coral...

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.

Investigating pH is intriguing, especially with these activities designed for an introductory chemistry or physical science class. Pupils use litmus paper to distinguish acids and bases and then make indicators from food products....

Using cabbage juice as a pH indicator, future scientists explore the effect of increasing carbon dioxide on the pH of the ocean and relate it to the health of coral reefs. Ideal for an earth or environmental sciences course, this lesson...
