At all points in its history, a significant proportion of the population of the United States had been born in other countries and regions. This being the case, American history can never be understood by just looking within its borders. The culture and politics of the US have always been profoundly shaped by the material and emotional ties many of its residents have had to the places where they were born. This map will allow you to begin to explore those connections at the basic level of demographic statistics.

Data set and map pertaining to foreign direct investment for all countries. This series shows net inflows (new investment inflows less disinvestment) in the reporting economy from foreign investors. Data are in current U.S. dollars. The World Bank specifies foreign direct investment as a World

In this activity, students study gas laws at a molecular level. They vary the volume of a container at constant temperature to see how pressure changes (Boyle's Law), change the temperature of a container at constant pressure to see how the volume changes with temperature (Charles’s Law), and experiment with heating a gas in a closed container to discover how pressure changes with temperature (Gay Lussac's Law). They also discover the relationship between the number of gas molecules and gas volume (Avogadro's Law). Finally, students use their knowledge of gas laws to model a heated soda can collapsing as it is plunged into ice water.

The Geniverse software is being developed as part of a five-year research project funded by the National Science Foundation. Still in its early stages, a Beta version of the software is currently being piloted in six schools throughout New England. We invite you to try the current Beta version, keeping in mind that you may encounter errors or pages that are not fully functional. If you encounter any problem, it may help to refresh or reload the web page.

Students will organize various stem items, make observations regarding those items such as their color, size, etc and then graph their observations.

Explore how the Earth's atmosphere affects the energy balance between incoming and outgoing radiation. Using an interactive model, adjust realistic parameters such as how many clouds are present or how much carbon dioxide is in the air, and watch how these factors affect the global temperature.

Data set and map pertaining to health expenditure per capita for all countries . The World Bank specifies health expenditure as a World Development Indicator (WDI) -- the statistical benchmark that helps measure the progress of development.

Being able to control the movement of electrons is fundamental for making all electronic devices work. Discover how electric and magnetic fields can be used to move electrons around. Begin by exploring the relationship between electric forces and charges with vectors. Then, learn about electron fields. Finally, test your knowledge in a fun "Electron Shooting" game!

Map of Africa coded by the number of underweight children per square kilometer. It is thus a measure of the absolute density of hungry individuals, a combination of hunger and population density.

Map of Asia color coded by infant mortality rate broken down by nation or subnational units (akin to US states or Canadian provinces). Shows the international differences, but also shows the (less substantial) differences within nations. The categories for the color coding have been changed slightly from the international standards to better fit the situation in Asia.

Map of Europe color coded by infant mortality rate broken down by nation or subnational units (akin to US states or Canadian provinces). Shows the international differences, but also shows the (less substantial) differences within nations. The categories for the color coding have been changed from the international standards to differentiate among the universally low infant mortality rates across Europe.

Data source updated on quarterly basis to assess Australia's national balance of good and services, credits, and debits.

Provides statistical information pertaining to homicides, rapes, robberies, and assaults committed by intimates.

Students will discover their personal political leanings through a website and express their opinion on their perceived accuracy of those findings

The microscopic world is full of phenomena very different from what we see in everyday life. Some of those phenomena can only be explained using quantum mechanics. This activity introduces basic quantum mechanics concepts about electrons that are essential to understanding modern and future technology, especially nanotechnology. Start by exploring probability distribution, then discover the behavior of electrons with a series of simulations.

Students will analyze data from the "State of the Bay" reports from the Chesapeake Bay Foundation while reviewing and completing the scientific method. The final assessment is a mission for students to create a persuasive speech or advertisement that will call for action to make changes that will positively impact the watershed with reasons why change is important. 

In this activity, students are split into groups and assigned different ocean regions. These include the Arabian Sea, Equatorial Pacific, North Atantic, and Southern Ocean. Each group uses Google Earth to view NASA satellite chlorophyll imagery and the cruise track of data collected as part of the U.S. Joint Global Ocean Flux Study. At three locations along each cruise track, chlorophyll-temperature-depth (CTD) and bottle data collected as part of the study can be downloaded. Students work with the data to identify oceanographic features as a function of depth and then make simple calculations.

Data set and map pertaining to labor force participation rates for women in all countries. The World Bank specifies female labor force participation as a World Development Indicator (WDI) -- the statistical benchmark that helps measure the progress of development.

Data set and map pertaining to total labor force participation rates for all countries. The World Bank specifies labor force participation as a World Development Indicator (WDI) -- the statistical benchmark that helps measure the progress of development.

Isaac Newton's famous thought experiment about what would happen if you launched a cannon from a mountaintop at a high velocity comes to life with an interactive computer model. You are charged with the task of launching a satellite into space. Control the angle and speed at which the satellite is launched, and see the results to gain a basic understanding of escape velocity.
