Middle schoolers examine human impacts on the water cycle. They compare/contrast the permeability of various materials for the purpose of engineering landscape drainage systems, and answer discussion questions.

Learners are introduced to Delaware's waterways as precious resources used for drinking water, water for agricultural and industrial uses, recreational areas, and as habitats for wildlife. They are introduced to wastewater discharges,...

Learners compare roofing materials to determine which ones reduce rain runoff. In this rain runoff lesson plan, students use a milk carton, stickers, soil, and more to create this activity.

Students conduct an experiment to show how water gets contaminated through neighborhood runoffs.

Students investigate the impacts of major rainfall and subsequent runoff on turbidity in lakes. They, in groups, develop a presentation of their research and/or write a paper summarizing their investigation.

Students create a model of a salt marsh to discover the impact of pollution and human activities on water-based habitats including bays and the ocean. They recognize the relationship between natural and developed areas. Students impact...

Students explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...

Students examine factors affecting water quality. They test water in a local body of water to determine its quality. They collect data and continue monitoring the water monthly. They assess water quality in the home and on the farm.

Students are led through three activities to explore the effect of temperature fluctuations on the growth and survival of aquatic plants, clams, and shrimp eggs.

Students investigate how excess nutrients enter a body of water, and the harmful effects they have on aquatic organisms.

Students investigate the San Francisco Bay Estuarine Research Reserve and watershed. In this estuary and watershed lesson plan, students complete 4 activities to better understand estuarine systems. They include studying the San...
