Science in the community- (Unit #1 Albert Einstein)

EINSTEIN BONUS: Go Geo-caching around Cedar City.

In our unit on Einstein and relativity, we are learning how modern day GPS uses the theory of relativity because gravity curves space and time which results in orbiting clocks ticking slightly faster on Earth.

“General relativity predicts that time will appear to run slow under stronger gravitational pull which means the clocks on board the satellites will therefore seem to run faster than a clock on Earth. Furthermore, special relativity predicts that because the satellites’ clocks are moving relative to a clock on Earth, they will appear to run slower. The whole GPS network has to make allowances for these effects.”

Yay for cool science! So go with your family and teach them about all you are learning in class.

Where in the world is Mrs. Westwood’s Science Class? (Unit #1 Albert Einstein)

“The important thing is to never stop questioning.”

During our first unit, we will be highlighting Albert Einstein and working in the fields of physics, energy, and technology. Albert Einstein is the father of modern physics. He came up with the world’s most famous equation E=mc2 (Energy = mass X the speed of light squared) which gave birth to the atomic bomb. He provided evidence that molecules and atoms exist through Brownian motion.

He basically re-wrote the law of gravity, which had been unchallenged since Isaac Newton. His theory of relativity has changed the way we think about space and time. He showed that matter causes space to curve, which produces gravity.

Example of the theory of relativity used today: GPS

In class we will be learning about how to use coordinates and GPS. We will also used Google Earth in class and pin-point our exact location.
