A Reason to Tweet

Snowtweets Project from the University of Waterloo provides a way for people interested in snow measurements to quickly broadcast their own snow depth measurements to the web. These data are then picked up by the Snowtweets database and mapped in near real time. The project uses the micro-blogging site Twitter as its data broadcasting scheme.

Participants can use a data visualization tool called Snowbird that allows them to explore the reported snow depths around the globe. The viewer shows where the reports are located and how much snow there is at each reported site.

How can you participate in Snowtweets?

1. Register for a free Twitter account at www.twitter.com.

2. Measure the snow depth where you live, work, or play.

3. Use your Twitter account to tweet the information to the project.

Maps for Science

As students investigate such national and global issues as climate change, water shortages, deforestation, endangered species, or shifting tectonic plates, online thematic maps can connect the issues to locations. Often these maps provide supporting data. Here are some sources of thematic maps that can be useful in the science classroom.

The Map Guide
Here is a collection of dozens of links to online maps of all types — physical, political, historical, and weather — from all parts of the globe.

Earth Pulse
In its coverage of conservation themes, National Geographic.com offers related maps showing impacts on oceans, climate, mineral resources, and terrestrial ecoregions.

Geologic Maps
To enable all of us to read geologic maps, the U.S. Geologic Survey published this easy-to-understand online guide.

Astronomy for Kids
The sky as seen from Indianapolis, Indiana, is mapped weekly at this site. Find a tool in the resources section to create your own map by your latitude and longitude or a nearby city name.

AAAS Atlas of Population and Environment
Along with extensive text on the impact of human populations on ecosystems and natural resources, the online atlas contains maps illustrating land use, population density, biodiversity, and more. With free registration you can create a personal copy of the atlas.

How Do Seasonal Temperature Patterns Vary Among Different Regions of the World?
Hands-on experience with recording temperature data on contour and dot maps is available to classrooms using the GLOBE Program.
