Lightning Strikes Thrice - Empire State Building

Description: Many people believe that lightning never strikes the same place twice but this video clearly shows that this is not true. A lightning rod consists of three main parts: a lightning rod at the top of a structure, a conducting wire, and a ground rod. This design allows electricity from the lightning strike to pass through directly to the ground without moving through the structure. This protects the structure and the people inside from possible fire and electrocution. This video shows that severe weather occurs in predictable ways and that humans must develop designs that can protect ourselves.

World Climographs

Description:  Climographs show the average temperature and precipitation in an area over the course of the year. Websites like climatecharts.net can be used to quickly identify patterns of climate around the world. Students can also ask causation questions related to the climate differences (e.g. How do mountains and wind patterns affect the climate in an area?, How do large bodies of water affect the climate in an area?)
