Snow on Sea Ice
Students examine different samples of ice and predict the amount of snow that has fallen in a given year. Using a calculator, they graph the various thicknesses. They analyze the graphs to determine the relationship between the snow and...
Curated OER
Secret Agents of Dissolved Oxygen
Students determine the changes in different types of water in a sealed container over time. They investigate how to measure dissolved oxygen, temperature, and carbon dioxide with calculator or computer probe-ware. Students determine the...
Curated OER
Testing for Conductivity
Students test the conductivity of selected liquids and solids. They test the circuit by touching the two free ends of the wires together and add salt little by little recording the data after each addition. Finally, students predict...
Curated OER
Currents: Bad for Divers; Good for Corals
Young scholars describe, compare, and contrast major forces that drive ocean currents. They discuss the general effects of topography on current velocity. They discuss how velocity affects the ability
Curated OER
This Old Tubeworm
Young scholars explain the process and significance of chemosynthesis. They develop their own graphic based on data of a biological community. They estimate the age of a given species as well.
Curated OER
Tracking the Salt Front
Young scholars 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...
