Curated OER
Acid-Base Indicators
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...
Curated OER
Acids and Alkalis
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...
Curated OER
Acids and Bases
In this acid and base worksheet, students test 13 different substances to determine their pH, the type of acid or base it is, the color the universal indicator turns, the color red litmus paper turns and the color blue litmus paper turns.
Curated OER
Acid(s)-Base(s) Detective
Students investigate acids, bases, indicators and universal indicators. For this acid and base lesson plan, students test 6 samples with litmus paper and determine if they are acids or bases. They separate out 7 samples using litmus...

Middle School Chemistry: P H and Color Change
Students see a demonstration of a color change using universal pH indicator and then change the concentrations of an acid and a base using a universal indicator to test the pH of the resulting solutions. Through an animation, they see...

Bbc: Gcse Bitesize: Types of Chemical Reactions
Bases are substances that can react with acids and neutralize them. Alkalis are bases that are soluble in water. The pH scale measures how acidic or alkaline a substance is. Substances with a pH lower than 7 are acidic, those with a pH...
