Time, Tide, and Quahogs
Students read tide tables for Waquoit Bay as the simulate determining the best time to go clam digging for a Wampanoag clambake. They graph the tide tables while realizing that the tides a Waquoit Bay are one hour later than those at...
Curated OER
Density Stratification and Ocean Circulation
Students examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.
Curated OER
Future Conditional
Students examine how toxic pollutants affect environmental and human health. They define key terms, watch a video, and answer discussion questions.
Curated OER
DNA Extraction From a Variety of Tissue Samples
Students, working in cooperative groups, extract very impure samples of DNA from a number of tissue samples. They determine how the samples can be preserved and how they are similar.
Curated OER
Measuring Water Quality
Students 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...
Curated OER
Quick Freeze (Demonstration)
Students witness an demonstration in which a bottle of club soda will go from a liquid to a solid when it is opened and the carbon dioxide is allowed to escape. This will help them understand that the freezing point of a solution will...
Curated OER
Bouncing Popcorn
Third graders meet a teacher challenge to work like chemists. They investigate with baking soda, water, salt, sugar, vinegar, and sprite to move a popcorn kernel from the bottom of a cup to the top. They experiment with different...
Curated OER
Brine Shrimp Survival
Students develop an understanding of how growth and survival of an organism depends on physical conditions. They design an artificial environment in which brine shrimp can thrive. Students determine the optimum salinity for hatching of...
Curated OER
DNA Extraction Laboratory Experiment
Students will visualize how DNA is extracted from cells by performing a simple laboratory experiment. They will then use this knowledge to further understand how scientists are using DNA extraction to try to clone human cells, and to...
Curated OER
Using Magnetotactic Bacteria to Study Natural Selection
Students demonstrate that living organisms may possess incredible adaptations which enable them to survive. They observe bacteria that are able to orient themselves using the Earth's magnetic field and formulate a hypothesis as to how...
Curated OER
Conversions at Sea
Learners demonstrate problem solving skills. Students complete word problems requiring unit conversions. They convert both metric and standard units. Learners must determine necessary information to solve problems.
Curated OER
Current Interactions
Students design an experiment to see how wind, temperature, and salinity work together to influence ocean currents and present it in a report format. They explain to their classmates how experiment findings relate to ocean currents.
Curated OER
The Buoyancy Factor
Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...
Curated OER
What Is Sustainability
Students investigate the concept of how people are dependent upon natural resources and how they can apply them to be maximized in usefulness. The students are encouraged to develop an appreciation for the environment. They conduct a...
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
Learners 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
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...
