What occurs following a natural disaster? High schoolers research this question and others as they investigate natural succession after a disaster. First, as they differentiate between primary and secondary succession, they explain...

As part of a study of voting rights in the US, class members examine Constitutional amendments connected with voting and the role of the Electoral College in the election process.

Your parents were both in different countries. You were born in the US. Documents and application forms ask you to identify your racial or ethnic classification. Which box do you check? Class members collect documents...

Be at the top of the food chain when it comes to understanding marine ecosystems. The 21st installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates marine ecosystems, ocean zones, and food...

Class members use an air quality monitor to measure the amount of gas-phase pollutants emitted by different sources. Groups choose three different sources and make predictions about what the monitors will detect. Teams then expose...

Water is crucial to survival. Scholars gain an appreciation for water by reading about it, learning about its atomic properties, and investigating its properties through six stations in a lab activity.

Show your classes how different means can represent the same data. Individuals collect household size data and calculate the mean. Pupils learn how handling of the data influences the value of the mean. 

What did gender have to do with the survival rates of the Donner Party? Using comparative box plots, classes compare the ages of the survivors and nonsurvivors. Using the same method, individuals make conclusions about the...

Under pressure! The second lesson of the series introduces the class to blood pressure and the impact of high blood pressure on the cardiovascular system. It helps learners make the connection between blood pressure and how the heart...
