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 study acidic and alkaline balance. In this acid and pH levels lesson, students read information about pH, the formation of acid rain and its impact on environments. Students then complete an experiment to learn about the...

Students test the pH of soil samples they collected from the field trip. In this chemistry lesson, students differentiate acids and bases. They write a lab report about the experiment.

Sixth graders describe the physical and chemical properties of acids. In this chemistry lesson, 6th graders test the acidity of different solutions. They identify acids and bases using the pH scale.

Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...

Students explore the Earth's crust by researching pH levels and acidity. In this environmental safety lesson, students identify the pros and cons of acidity within soil and how it affects plants. Students collaborate in a pH level...
