Students study salty and fresh waters.  In this harbor estuary lesson students complete a lab activity on salinity and describe what happened. 

Learners are introduced to the various methods of measuring water quality. In groups, they test various water samples using the different methods, writing them down for pH, oxygen, salinity, and nitrate levels. They use their data to...

Students use Hudson River salinity data to create a line graph that shows the location of the salt front, and use math skills to explore how this location varies over time. They use the graph to estimate the location of the salt front...

Students view a video and then complete lab exercises to help them explain marine communities and animals in them.

Students explore the environmental factors that influence where fish live and determine the makeup of fish communities in the Hudson. They interpret guided observations and measurements to assess patterns, sequences and relationships.

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Students study natural habitats, aquatic life, renewable and non-renewable resources. They discuss conservation efforts for sea otters and desert toad in this units.
