Nation Examination: Spain

Image
 Ole! Spain is on the Iberian Peninsula and is bordered by the Pyrenees Mountains & France, Portugal, the Mediterranean Sea, and the Atlantic Ocean.  Spain and Portugal share a lot of the same history. The people who had originally settled Spain spent thousands of years moving from hunting and gathering to farming and keeping livestock. Once they established permanent settlements, their world expanded by contact with the Phoenicians and Greeks. This was primarily along the Mediterranean coasts where a number of city states were set up.  During the same time period, the Celts decided to settle the rest of Spain where they lived a more nomadic life shepherding their sheep between the summer northern highlands and the winter central plateau.   Slowly Spain came under full control of the Roman Empire. They were called "Hesperia" and enjoyed the influence of Rome and its many building innovations such as bridges and aqueducts. When the Western Empire of Rome fell in the 5th ce

Here Comes the Sun - Solar Energy

 Meet the Sun:  This amazing sun is our closest star. It keeps us warm, gives us light and life. It is also the center of our solar system. The sun is a star that is closest to us. There are lots of stars - just look outside at night! The next closest stars are Alpha Centauri and Proxima Centauri. Each of these stars have a few planets too!  Proxima Centauri, has two planets: Proxima Centauri b and Proxima Centauri c (creative names - eh?) Neither of these planets can sustain our type of life but it is interesting to think of the number of stars out there - each with at least a few planets - maybe there is another planet with life on it too!  The sun is so important to us because it creates energy and gives us light and heat - but how exactly does it create this energy? Well - the sun is a ball of gas - quite literally - and in the center of its ball - it has all these chemical reactions that causes energy to escape through the surface of the sun. Like nuclear fusion - the sun has its

Titanic Trivia

--Opening The whole movie except the present day scenes and the opening and ending credits are two hours and 40 minutes long which was the exact time it took for the Titanic to sink. The collision scene with the iceberg lasted 37 seconds in the movie and in real life. While filming in Nova Scotia - somebody (the suspicion was an ex-employee) put a hallucinogenic (PCP or angel dust) into the clam chowder that was served to the cast and crew. People started doing crazy things - the director of photography led a conga line, another crew member started to demand to see a priest, the assistant director started taking to Cameron while talking into her walkie talkie - even though she was right in front of him! Cameron realized what happened and induced vomiting on himself. About 50 people went to the hospital but all were eventually fine. --Loading Scene The Swedish phrases that Sven and Olaf exchange during the card game translate into the following: Olaf: "Idiot!" Sven: "Shut

Doppler Effect

 The Doppler effect can be "felt" when a car drives past you. It sounds like it's getting louder - then it passes you and it sounds just different - you may have expected it to get softer - but it doesn't - the sound completely changes. The noise coming from the car never changed - and you never changed but the distance between the car and you changed. This is my favorite illustration - the car continues to emit its sound in the form of waves but depending on where the observer or person is standing - they are effected by either looooooong waves that don't come very often (aka low frequency) or short waves that come often (high frequency). This next illustration adds in the fact that if the object and the observer are stationary - then the wave lengths are not close together and not long wavelength - they are just right. But when the object moves closer to the observer - the waves are more bunched up so there is a smaller wavelength and a higher frequency (number

Dew Point

 My little guy and I were out for an early morning walk when he made the observation that the grass was wet but not the sidewalk. I told him that was "the dew" but he wanted to understand the topic more. So - here it is - the science "lesson" for the day on dew. Meet Dew: When an object (such as a plant) gets SO cold - it cools the air around it. Then the water that is in the air around the object turns from water vapor (a gas) to water (the liquid!) and settles on the object.  video about dew Want to calculate the dew point? That's the temperature an object needs to be in order for dew to form on it! You get the temperature of the air in Celsius (call that "T"); and get the relative humidity (call that "RH") and do this fancy approximation calculation and it will spit out the dew point (call that Td which is the temperature that an object needs to be in order for dew to form on it!) Td = T - ((100 - RH)/5.) ...are you like me and Fahrenheit
