Students investigate the causes of hypoxia, the characteristics of a watershed, and how the actions and management practices of people can both negatively and positively affect aquatic ecosystems.

Students take a virtual trip to a Catfish Aquaculture Pond and analyze soil bacteria to determine how many nitrogen cycle bacteria are present. They graph the number of colonies present and use data to determine ammonium levels in the soil.

Students are introduced to tree structure and use. They identify their special tree using all senses except sight. Students identify six different internal parts within a cross section of tree trunk (bark, phloem, xylem, cambium,...

Seventh graders design and conduct experiments to determine what environmental factors favor decomposition by soil microbes. They use chunks of carrot for the materials to be decomposed, and their experiments are carried out in plastic...

Young scholars perform experiments designed to grow plants and bacteria in a controlled environment.  In this ecosystems lesson students investigate varying conditions for growing plants and bacteria. 

Students determine what part of a plant they are eating when they eat different fruits and vegetables.

Second graders, using large colored poster board, explore photosynthesis and its effect on the food chain and survival of organisms.

Students work in groups to predict which condition produces more breaths per minute. Groups record their breathing rates during rest periods and periods of activity. They graph their results and make comparisons to their predictions.

Young scholars examine how global wind and water patterns aid in the spread of worldwide pollution. In groups, they read articles about the domino effect of pollution and create posters displaying its journey. On blank world maps,...

Students explore the basics of ecology. They discuss ecological succession, the water cycle and human impacts on the environment. Students explore the owls, succession, the human impact on the environment and complete the "Incredible...

In this oceans quiz worksheet, students complete a 10 question multiple choice quiz covering a variety of concepts related to the ocean.

Sixth graders investigate erosion. In this erosion lesson, 6th graders explore how farming changes the environment. Students construct an erosion model and research ways to protect the soil from excess mud generated by farming.

Students study ponds and wetland ecosystems and examine the food chains and webs in them.  In this aquatic ecosystems lesson students answer questions about the diversity of the flora and fauna in a pond. 

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 define the terms estuary and watershed. They conduct an experiment to determine the density differences between fresh and saltwater. They examine the salinity distribution of the Peconic Bay Estuary.

Students explore how the heart pumps blood through its valves. They observe fluid moving through a one-way valve and build a model of a valve. in addition, they explore biotechnology design.

Students build a soil erosion model to study the importance of soil conservation. They investigate how land forms from both constructive and destructive forces.
