A video and laboratory investigation are highlights to this lesson on acidification of ocean water due to increased atmospheric carbon dioxide. Using bromothymol blue (BTB) as an indicator, pupils analyze the amount of carbon dioxide...

Explore the range of pH using an assortment of household liquids. Scholars create their own pH indicators from cabbage and determine the pH of several liquids. To further their exploration, individuals use the same liquids to create...

Eighth graders explain the difference between acids, bases and neutral solutions. In this chemistry lesson, 8th graders describe the properties of each. They determine the pH of an unknown solution using the indicator paper and pH scale.

Students investigate acids, bases,and pH. They test the acidity and basicity of various household items using litmus paper. Using their results, they rank the substances according to pH and identify the contributing chemical on the label.

Students experiment to determine the difference between an acid and a base. They study the concept of adding a buffering agent to make an acid more basic. They study the pH scale.

Students examine the pH scale. They research common products and determine their pH level. They create their own pH scale and place their products in the appropriate place.

Students investigate acids, bases, and pH, and related this knowledge to the problem of acid deposition.

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

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

Students test unknown solutions for pH levels to determine which organism can live in each environment. They name three substances that they think are acids. Students determine a solution is an acid or base. They define the term pH.

Students explore pH levels of different substances. In this lesson about pH, students work together in three to four groups to test substances. moving between three different stations performing tests on the substances to determine...

Young scholars participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors...

Here's proof that small-scale labs lead to big-time learning. Introduce acid-base interactions to middle school scientists through a microscale chemistry lab. Pupils combine a variety of solutions and use indicators to obtain approximate...

Students apply the scientific method and safety rules to aquatic pH. They test unknown solutions for pH levels.

Ninth graders complete an experiment to determine the pH values of a variety of common household substances. They use red cabbage to find the indicator colors of the pH range. They complete a data table that includes a prediction and...

Students discuss places they have been where the air seemed hard to breathe. They discuss if they could "see" the humidity or smell. Students discuss ways this might relate to the fish in the aquarium. The teacher introduces pH and how...

Students investigate the pH of various solutions with indicators. In this acids, bases and indicators lesson plan, students use a variety of indicators to test solutions for their pH. Students determine which indicators are the best to...
