In this virtual science lab, students learn how a pH scale works and how to calibrate a pH meter.

This virtual lab activity where students perform the method of successive dilutions using HCl, NaOH, a pH meter, and universal indicator solution to help understand the logarithmic nature of the pH scale.

Test the pH of everyday liquids such as coffee, spit, and soap to determine whether each is acidic, basic, or neutral. Investigate how adding more of a liquid or diluting with water affects pH.

Review examples of macro and micro pH scales of a variety of substances available in a drop down menu. Create a solution to measure.

A video tutorial introducing the pH scale as a representation of the concentration of protons. [4:45]

Students investigate the pH level of household substances by testing a variety of common compounds. Substances are tested with pH strips and placed on the continuum of the pH scale range of 1 to 14. After testing a solution, the student...

[Free Registration/Login Required] Arrange the items shown next to their corresponding pH value on the scale.

Discover where solutions fall on the pH scale using this detailed pH chart.

This lesson focuses on acids and alkalis including acidic and alkaline solutions, neutral solutions, indicators and the pH scale, the colors for litmus paper, and a link to a test.

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

[Free Registration/Login may be required to access all resource tools.] Definition of pH and the strength of acids and bases. How to use the pH scale and why pH is important to living things.

This lesson will introduce the concept of pH, acids and bases. It is 3 of 3 in the series titled "pH Scale."

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...

This lesson focuses chemical reactions using acidic and alkaline solutions, the pH scale which measures the acidity or alkalinity of a solution, and how to use a pH meter. A link to an assessment is also provided.

This is a great source of chemistry experiments and information dealing with pH. Learning objectives are provided to explain the basis for each activity. Japanese and Chinese versions are also provided.

In this lesson on exploring acids and bases, students will explore the pH scale and how is it related to acids and bases by learning key vocabulary terms and visuals related to the chemical process of neutralization.

Try putting different liquids into a virtual pH tester to find out whether they are acids or bases.

STEM Earth Science lesson in which students learn about measuring and determining the PH of a substance and the impact of acid rain on the environment due to changes of PH.

Students will add acidity to a healthy lake to see what happens to plants and animals in this interactive activity adapted from EcoKids.

Draw a graph of any function and see graphs of its derivative and integral. Don't forget to use the magnify/demagnify controls on the y-axis to adjust the scale.

[Free Registration/Login Required] Arrange the household items so that their pH corresponds to the scale.

How acidic is your water? "In this experiment, you will measure the pH of natural water located near your home or school."

Acting as an overview from the General Chemistry Virtual Textbook, this site acts as one in a series of slides on acid-base systems. This particular slide deals with coordinating pH graphs.

In this activity, students determine the pH of liquid samples. They get familiar with the pH scale, create graphs comparing pH levels, and compare data displayed as a scatter plot, a boxplot, a histogram, and a bar graph.
