The pH scale

Did you know strong bases can feel slippery and slimy? Lesson allows scholars to practice using the pH scale to identify acids and bases and their strengths. By changing the concentration of an acid and a base, they create the entire...

Most things naturally strive for balance, and acids and bases are no exception. Neutralization of acids and bases allows scholars to explore the color changes associated with the pH scale. After this exploration, pupils neutralize two...

Students review properties of materials and define what pH tells them about matter.  In this pH levels lesson, students determine whether materials are acids or bases using indicator substances.

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Once I told a chemistry joke, but there was no reaction. A STEM lesson plan using the inquiry method covers the topics of acids and bases. Young chemists find the pH of substances; measure and classify substances; design a question and...

Students investigate about acids, bases, and pH and relate this information to the problem of acid deposition. They use pH paper, students test common household substances to determine whether they are acidic, basic, or neutral. Pupils...

Fourth graders compare the color of cabbage water when acids and bases are mixed in. In 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...

What is pH and how is it measured? What happens when acids and bases mix? In an extensive 5E experiment and lesson, young chemists create their own pH paper, test the pH levels of several substances, evaluate their results, develop and...

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...

Sixth graders correctly identify items as acids or bases by using a pH test, list the common properties of acids and bases and explain the pH scale.
