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.

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...

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

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.

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.

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.

The students will analyze the pH of four citrus fruits: lime, lemon, orange, and a grapefruit, and then they will analyze the pH of four different types of stain removers: Shout Advanced, Spray 'n Wash Max, Oxi Clean Laundry, and Clorox...
