Mattel and Toy Safety Bus 250 Prof. J. Reece Amanda Wagoner November 18‚ 2013 Mattel and Toy Safety Mattel is an American based toy manufacture that was founded in 1945 by Harold "Matt" Matson and Elliot Handler. The company has been headquartered in El Segundo‚ California since it first opened. However‚ in 2007 the toy manufacture faced hard times when they had to do multiple recalls on their children’s playthings due to unsafe parts and hazardous materials (such as lead paint) the company faced

Electron Gun - Effects of a Magnetic Field Purpose: The objective of this experiment is to study the motion of an electron in a magnetic field and to establish (show/verify) a relationship between the magnetic strength and the distance the electrons are deflected. Theory and Procedure: The electron gun is an instrument that consists of an electron source (which emits electrons and focus the stream into a beam)‚ a magnetic coil (which uses a voltage to create a magnetic field that deflects the beam

charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT. A magnetic field perpendicular to the deflecting electric field is produced using a pair of bar magnets. The position of the magnets is adjusted so as to cancel the deflection of the electrons. The knowledge of the deflecting potential and the magnet field

Kathryn Bigelow‚ director of The Hurt Locker could have never imagined her movie winning six academy awards. While the opinion from the audience played a role in these winnings‚ the technical aspect of the movie all the way down to the first shot of the movie‚ played the biggest role in this achievement. Bigelow used things such as moving camera shots‚ camera angles‚ lighting‚ and the use of long shots to create a realistic feel throughout the movie. Throughout the movie it appears that most of

“Toy Story” Movies have been a big hit for many years. Billions of dollars have been spent by people just to watch these fascinating moving pictures. “Toy Story” ‚ which came out in 1995‚ is an excellent example of one of these movies that appeared in theaters. It is an animated representation of what toys do when no one is in the room watching them. Woody‚ the cowboy‚ is Andy’s favorite toy and the leader of all the other toys. On Andy’s sixth birthday his parents got him a Buzz Lightyear doll

kinds of toys that little girls receive give messages about feminine traits such as; dolls‚ dress ups and fairies. The kinds of toys that little boys receive give messages about masculinity for example; cars‚ trucks and building blocks. Infant toys tend to be the same for both boys and girls. These toys are mostly multicolored‚ make noise‚ play a song‚ light up or roll around. However from ages one to four children’s toys begin to send distinct messages about gender roles. Girl’s toys start to
