Authorized by the Older Americans Act, the program provides training for low-income, unemployed seniors. Participants also have access to employment assistance through American Job Centers. SCSEP participants gain work experience in a variety of community service activities at non-profit and public facilities, including schools, hospitals, day-care centers, and senior centers.
Lightning and Thunder. Lightning is the spark caused when electricity that has built up in a thunderhead discharges. One theory is that air in motion rubs particles of ice and rain moving downward against particles moving upward. As the particles rub together they become charged with static electricity.
A lot of theories has been discussed concerning causes and creation of thunder. In the third century BC, it was believed that thunder is caused due to collision of clouds. However, the most accepted theory was conceived in the 20th century. According to this theory, lightning causes thunder sound.
