Jeopardy (saved in groups)

Tuesday, February 4, 2014The potato chip was invented in 1853 by George Crum. Crum was a Native American/African American chef at the Moon Lake Lodge resort in Saratoga Springs, New York, USA. French fries were popular at the restaurant and one day a diner complained that the fries were too thick. Although Crum made a thinner batch, the customer was still unsatisfied. Crum finally made fries that were too thin to eat with a fork, hoping to annoy the extremely fussy customer. The customer, surprisingly enough, was happy - and potato chips were invented!

Wednesday, February 5, 2014Lonnie G. Johnson (1949- ), was born in Mobile, Alabama. He always loved creating and experimenting. At the age of 18, he built a remote-controlled robot, "Linex," and won a national award for his invention. The robot was made from junkyard scraps. He attended Tuskegee Institute, where he earned a B.S. degree in Mechanical Engineering in 1972 and a M.S. degree in Nuclear Engineering in 1974.After college he joined the Air Force and later went to work for NASA, where he earned many awards, including award-winning work for the Galileo Jupiter probe and the Mars Observer project. One of his great achievements was the Johnson Tube. Of all his inventions, he is most noted for the Super Soaker water toy.In 1982, Lonnie did not mean to invent the powerful water toy, but was tinkering around when a homemade nozzle at his bathroom sink shot a spray of water, and viola! The Super Soaker was born!

What is a line of symmetry?

• A line on which a figure can be folded so that both sides match.– Maryland Content Standard 2.E.2 – Identify and describe

symmetry in geometric figures or pictures. (Up to four lines of symmetry)

To be a line of symmetry, the shape must have two halves that match exactly.

When you trace a heart onto a piece of folded paper, and then cut it out, the two half hearts make a whole heart.

The two halves are symmetrical.

Which of these flags have a line of symmetry?

Thursday, February 6, 2014Garrett MorganBorn: 1877Safety Hood, Traffic Light. Morgan's first well-known invention was the safety hood, a forerunner of the gas mask. When 32 workers in Cleveland, Ohio, were trapped during a tunnel collapse in 1916, Morgan and several volunteers using the masks were able to reach the trapped men and rescue several survivors. In 1923, Morgan patented his best-known invention, the three-way traffic signal, based on signs that signaled stop and go. He sold his patent rights to General Electric, which developed an electrical version.Died: 1963
