Learn about one town's conflict over the issue of spraying pesticides to combat disease-carrying insects, in this video segment from Greater Boston.
In this video segment adapted from NOVA scienceNOW, scientists discuss a family of genes called FOXO that can significantly extend life span in worms—and in humans.
Our agricultural system is made up of interconnected resources. The availability of these resources affects how much food we can produce. In this module, you will explore the resources that make up our agricultural system in order to answer the question: can we feed the growing population? Food production is faced with an ever-growing number of challenges. Growing enough food depends on the availability of resources such as arable land, sunlight, rain, and organic matter. Throughout this activity, you will explore land uses and soil quality through graphs of land use and crop production. You will run experiments with computational models to compare the effect of different management strategies on the land. You will not be able to answer the module's framing question at the end of the module, but you will be able to describe how humans can maintain and replenish important resources to be able to produce food long into the future.
This is an interactive visualization of the Carbon Cycle, through short-term and long-term processes.
Interactive visualization that provides a basic overview of the Earth's carbon reservoirs and amount of carbon stored in each, CO2 transport among atmosphere, hydrosphere, geosphere, and biosphere, and a graph comparing global temp (deg C) and atmospheric CO2 levels (ppm) over the past 1000 years.
During this module, students take a virtual mobile lab drive with scientists to investigate and learn about atmospheric carbon gases, their sources, and impacts on air quality.
