How many times have you seen a huricane or tornado warning?   Early warnings of danger save lives.   That is the main purpose of radar, to provide an early warning so that people can react appropriately to changing situations. 

What is radar?  Radar is the use of radio waves that are transmitted and reflected in order to determine the location of objects that are out of sight. 

Where did radar come from?   Radar (radio detection and ranging) is a result of experiments from as far back as the 1880s and include research from many nations around the world.   The United States Navy began seriously experimenting with radar in the 1930s at the U.S. Navy Research Laboratory right here in Washington, D.C.

Join this virtual program to learn more about this critical invention and observe a guided demonstration that illustrates radio-wave reflection.   This program will be facilitated by museum educator, Mike Galloway.

STEAM Saturdays is a series of two-hour demonstrations held on the second Saturdays of every month.  Topics are generally related to science, technology, engineering, arts, and mathematics, or "STEAM".

Occasionally, the program may be held on a different day to coincide with special observances.  Check our website for the most updated listing.
