National Geographic has really useful interactives in many areas of science, but one in particular I love to use is "Forces of Nature." This is useful for Earth or weather science. This online "lab" takes a close look at tornados, earthquakes, hurricanes and volcanoes. 1. Science Standard -- Good for grades K-8. Standard E -- Earth and Space Science. 4.5 Describe the weather commonly found in Wisconsin in terms of clouds, temperature, humidity, and forms of precipitation, and the changes that occur over time, including seasonal changes E.8.3 Using the science themes during the process of investigation, describe climate, weather, ocean currents, soil movements and changes in the forces acting on the earth 2. Integration -- Use in conjuction with a current event surrounding weather or earth activity. Case studies section on the website shows facts and information about actual natural disasters in history. 3. This interactive is easily adaptable to any age group or audience. Higher level students may maneuver through the site independently while younger students or non-readers can watch as the teacher or another student sets off an earthquake. The only drawback is that there is no audio.
