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.

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...

Learners 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. Learners collaborate in a pH level...

The first STEM lesson in a group of 10 explores composting. After discussing how to make a better tomorrow, classes are challenged to track garbage in their communities, visit a local waste management facility, and conduct a survey...

Learners 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.

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

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Young scholars determine the density of different substances. In this physical science lesson, students rank them according to their density. They discover the relationship between volume and density.

Students perform several tests on liquids. For this general science lesson, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.
