Curated OER
A Salty Experiment
Students study salty and fresh waters. In this harbor estuary lesson students complete a lab activity on salinity and describe what happened.
Curated OER
The Floating Golf Ball
Fourth graders discuss density. In this floating golf ball lesson students complete a lab activity on density while working in groups.
Curated OER
Water Density Boundaries
Students create observable layers in water that represent a separation based upon density differences. They model density boundaries using differences in temperature and salinity. They, in groups, perform a meaningful experiment...
Curated OER
Water Density and Stability Lab
Students observe how different water densities and salinity control the depth at which different water masses occur. Submarines are used as a case study. This is a well-designed with an excellent worksheet.
Curated OER
Exploring Marine Objects
Students identify the sources of water on Earth. In this life science lesson, students list the different plants and animals that live in the ocean. They explore marine objects in the lab and draw them.
Curated OER
Water Quality Monitoring
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...
Curated OER
Learning Lesson: Salt 'n Lighter
Students participate in a demonstration showing that as salinity increases density increases as well. They also examine the different densities of air. They discuss the amount of water displaced by large ships.
Curated OER
Tracking the Salt Front
Students manipulate Hudson River salt front data from October 2004 -
September 2005 to locate the high and low points of the salt front for each month, They determine the range for each month, determine the modal range for each month,...
Curated OER
Locating the Salt Front
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...
Curated OER
Where Do Fish Live in the Hudson?
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.
Curated OER
Fish Communities in the Hudson
Students use tables of fish collection data to draw conclusions about where fish live in the Hudson Estuary. Given available data they interpret organized observations and measurements and recognize simple patterns, sequences, and...
Curated OER
Environmental Differences
Students observe and conduct an experiment to see whether differences in salinity (the environment) have an affect on the hatching rate and survival of brine shrimp.
Curated OER
NOAA Research Project
Young scholars research any topic relating to the National Oceanic and Atmospheric Administration (NOAA) research cruise that Mrs. Richards be participating in.
Curated OER
Water World
Students explore the various steps of the water cycle. They identify the three steps in the water cycle and how they are related. Students describe three ways to conserve water. Students explore the origin of the water source that...
