It explained why things fall down and why the planets orbit around the Sun.]]> 2017-04-30 22:36:19 UTC https://padlet.com/marsha89/scientificbreaks/wish/169085757 marsha89 https://padlet.com/marsha89/scientificbreaks/wish/169086898 Michael Faraday discovered that when a wire carrying an electric current is placed next to a single magnetic pole, the wire will rotate.  Faraday's experiment created the first generator, the forerunner of the huge generators that produce our electricity.]]> 2017-04-30 22:50:04 UTC https://padlet.com/marsha89/scientificbreaks/wish/169086898 marsha89 https://padlet.com/marsha89/scientificbreaks/wish/169087223 Albert Einstein's complicated theory states that the speed of light always remains the same—186,000 miles/second (300,000 km/second) regardless of how fast someone or something is moving toward or away from it.]]> 2017-04-30 22:54:50 UTC https://padlet.com/marsha89/scientificbreaks/wish/169087223 marsha89 https://padlet.com/marsha89/scientificbreaks/wish/169089913 James Watson and Francis Crick found the double-helix structure of DNA. It’s made up of two strands that twist around each other and have an almost endless variety of chemical patterns that create instructions for the human body to follow. ]]> 2017-04-30 23:27:39 UTC https://padlet.com/marsha89/scientificbreaks/wish/169089913 marsha89 https://padlet.com/marsha89/scientificbreaks/wish/169090623 Wilhelm Roentgen discovered x-rays go right through some substances, like flesh and wood, but are stopped by others, such as bones and lead. This allows them to be used to see broken bones or explosives inside suitcases, which makes them useful for doctors and security officers.]]> 2017-04-30 23:36:08 UTC https://padlet.com/marsha89/scientificbreaks/wish/169090623 marsha89 https://padlet.com/marsha89/scientificbreaks/wish/169091224 Understanding relativity and its purpose.]]> 2017-04-30 23:44:10 UTC https://padlet.com/marsha89/scientificbreaks/wish/169091224
