President Barack Obama rode a bicycle at the White House Science Fair on April 22. But it wasn’t an ordinary bike. As he pedaled, the President stayed in place, while the energy from his pedaling powered a water filtration (过滤) system. He was testing an invention created by a team of 14 students from Northeast High School, in Oakland Park, Florida.

Payton Karr, 16, and Kiona Elliot, 18, attended the fair as representatives of the project.“We were hoping President Obama would ride the bike, but we didn’t actually expect him to,” Payton told TFK. “ It really meant a lot.” Kiona agreed. “It was pretty awesome to see the invention, which was invented by a group of 14 high school students and one teacher, along with the help of community members, got the interest of the leader of our nation,” she said.

The project was an idea that came about after one of the Northeast students, Kalie Hoke, visited Haiti after the terrible 2010 earthquake and saw how difficult it was to find clean water. The students invented a portable(便携的), bicycle-powered emergency water filtration system, which can provide 20-30 people with drinking water in a 15-hour period. The teens hope their invention will one day be used by relief organizations like the Red Cross. “ They can take it to places after natural disasters so that water can be clean for the people there,” said Payton.

Payton and Kiona were among the 100 students from more than 40 states invited to the third annual White House Science Fair, in Washington, D.C., which is also attended by leaders in science and education. President Obama started the event in 2010 to stimulate students interested in STEM (Science, Technology, Engineering, Maths).“Well, if you’re a young person and you produce the best experiment or design, you ought to be recognized for that achievement,” Obama said when he first announced the fair.

President Obama praised the projects during a speech to attendees after the fair. “The science fair projects of today could become the products and businesses of tomorrow,” he said. “If you’re inventing things in the third grade, what are you going to do by the time you get to college?”

Abraham Lincoln was born in Kentucky on February 12, 1809. When he was a small boy, his family moved to Indiana. Here, his mother taught him to read and write. Lincoln had very little formal education, but he became one of the best-educated men of the Great West.

When Lincoln was a young man, his family moved to the new state of Illinois. Lincoln had to make a living at an early age, but in his spare time he studied law. He soon became one of the best-known lawyers in the state capital at Springfield, Illinois. It was here that Lincoln became famous for his debates with Stephen A. Douglas on the problem of slavery (奴隶制度).

In 1860, Lincoln was elected President of the United States. He was the candidate of the new Republican Party. This party is against the creation of new slave states. Soon after his election, some of the Southern states quit from the Union and set up the Confederate States of America(美利坚联盟国). This action resulted in the terrible Civil War which lasted from 1861 to 1865.

On January 1,1863, during the war, Lincoln published his famous Emancipation Proclamation(解放宣言). In this file, Lincoln announced that all the slaves were to be free from that day. In 1865, after the war ended, another file was added to end the slavery everywhere in the United States. Early in 1865, the Civil War came to an end with the defeat of the South by the North. 

Only a few days after the end of the War, Lincoln was shot by an actor named John Wilkes Booth. The President died on April 14, 1865. In his death, the world lost one of the greatest men of all time.
