What are the different ways to test for pH? First, scholars explore the pH scale and a common way to test for acidity and alkalinity. Then, they learn about the importance of pH in food safety and why variance in pH could potentially...

Where did the pH scale come from? Take a deeper look at a most important measure of ion concentration using a simulated physical determination. Young chemists prepare a series of dilutions after determining a dilution factor for the...

Pupils learn how to control food spoilage by adjusting the food's pH. They see that one of the most dangerous bacteria can grow in food if people don't handle and store food properly. Using knowledge of the bacteria's preferred pH,...

Support your young scientists' knowledge of logarithms with a quick video lesson. The instruction first presents the relationship between a base-10 logarithm and an exponential equation. It then demonstrates how to use a calculator to...

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

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.

In this advanced simulation, students experiment with changing the ion ratios in solutions and thus the pH. The experiment can be viewed on a macroscopic or microscopic level, or customized.

In this simulation, students learn how changing the concentration of a solution affects the pH level.

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

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

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.

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.

Learn where acids and bases fall on the pH scale and the correlation between hydrogen and hydroxide ions. See many examples of how to calculate the pH of a substance. Also find links to the chemistry textbook and tutorials.

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

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.

Create shapes using colorful blocks, and explore the relationship between perimeter and area. CCSS.Math.Content.3.MD.C.7.a Find the area of a rectangle with whole-number side lengths by tiling it

Perform virtual lab experiments safely. Pour and mix specific amounts of various solutions on screen and observe changes in temperature and pH. Choose glassware and other tools (ie. bunsen burner, scale) to assist with virtual lab...
