In this video segment from Nature, scientific experiments test how ravens think.
The Grand Challenge
This lesson introduces the MRI Safety Grand Challenge question. Students are asked to write journal responses to the question and brainstorm what information they will need to answer the question. The ideas are shared with the class and recorded. Students then watch a video interview with a real life researcher to gain a professional perspective on MRI safety and brainstorm any additional ideas. The associated activity provides students the opportunity to visualize magnetic fields.
Students learn about the advantages and disadvantages of the greenhouse effect. They construct their own miniature greenhouses and explore how their designs take advantage of heat transfer processes to create controlled environments. They record and graph measurements, comparing the greenhouse indoor and outdoor temperatures over time. Students are also introduced to global issues such as greenhouse gas emissions and their relationship to global warming.
Demos and activities in this lesson are intended to illustrate the basic concepts of energy science -- work, force, energy, power etc. and the relationships among them. The "lecture" portion of the lesson includes many demonstrations to keep students engaged, yet has high expectations for the students to perform energy related calculations and convert units as required. A homework assignment and quiz are used to reinforce and assess these basic engineering science concepts.
Pattern Blocks - a Virtual Manipulative
Use six common geometric shapes to build patterns and solve problems.
Using this virtual manipulative you may:
-Add a block to the workspace
-Rotate a block
-Change the color of a block
-Remove a block
-Clone a block
-Clear the workspace
There are more instructions to the right of the manipulative. Activities can be found above the workspace.
Social and Political Structures of Early Modern Europe - European Civilization from the Renaissance
An introduction to European history from around 1500 to the present. The central question that the course addresses is how and why Europe-- a small, relatively poor, and politically fragmented place-- became the motor of globalization and a world civilization in its won right. Put differently how did �western� become an adjective that, for better and often for worse, stands in place of �modern.� Our approach will be broadly cultural, i.e. it approaches politics, economics, social life,
How the Arctic Ecosystem Might Change
In this video segment adapted from the National Film Board of Canada, learn why the unique Arctic ecosystem may be replaced if global warming continues to melt sea ice.

Hurricane Erin from MODIS: September 5, 2001
Terra-MODIS is one of many satellites that NASA has that helps us here on the ground. Keeping track of Hurricane Erin, the instrument MODIS gives us a birds-eye view.
