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 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...

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

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...

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.

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...

Students 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. In this general science instructional activity, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.
