My Favorite Thing About My Family Is…

My favorite thing about my family is how supportive they are.  They are always close by to cheer me on.  If it’s late and I’m struggling with math, my mom will try to help me out, but not give me the answer.  When I’m sad, my sister cracks a joke to make me feel better.  My dad Skypes us sometimes to see how we’re doing which always puts a smile on my face.  My two cats love to hop in my bed and get petted, it makes them happy which makes me happy.

Robert Boyle

Robert Boyle is most known for making modern chemistry and being a modern chemist.  He was born 1627 in Lismore Castle, which is in Ireland.  He was taught French, Greek, and Latin when he was eight years old.  He also studied Galileo’s works.  He went to the “Invisible College” (A private college most people didn’t know about) when he was seventeen years old.  He devoted his whole life to the scientific method.  He didn’t believe in the Greek’s view on the four elements water, fire, earth, and air. He was also known for Boyle’s law, according to Wikipedia.org, “The absolute pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system”.  This helped people understand the human breathing system which contributed to scuba diving.  He wrote a popular book called “The Skeptical Chemist” in 1661.  He is my favorite person this week because when I drink from the straw I know he was the one who figured out how a vacuum works.

Blaise Pascal

Blaise Pascal was born in 1623,  in Auvergne, France.  In 1642 he started working on calculating machines to help his father (who was a tax collector) more accurately and efficiently do addition and subtraction.  He is one of the two people who made a calculating machine.  Even though Pascal’s machine was invented twenty years after the first one, he gets credit because he was the one who shared his work.  He was also a mathematician, physicist, inventor, and writer.  He is most known for creating Pascal’s Law.  As Wikipedia.org states ” Pascal’s Law is a principle in fluid mechanics that states that a pressure change occurring anywhere in a confined incompressible fluid is transmitted throughout the fluid such that the same change occurs everywhere”.  I will kind of explain it.  Say you have a dam, behind it is a lake filled with water, that lake puts an amount of pressure on the dam wall.  If you remove all the water from the lake except a paper thin wall the same depth the lake was, it will put the exact same amount of pressure as that full lake did.  His work helped people at his time understand pressure and water.  Later on his work led to use in car design and hydraulic brakes were invented.  He is my favorite inventor because I feel the pressure in my ears when I swim to the bottom of a pool and now I know he explained why.

My Talent

One of my talents is that I make fruit dishes for my mom, either it is a funny face or just a pretty design, but when we make some for ourselves it doesn’t look as pretty.  I am really good at combining nutrition and food art.

I can also sprint around 10 mph which is pretty fast.  I can outrun just about anybody.  Not only am I fast, but I can maneuver quickly to confuse people in games of tag.

I can make historically accurate looking airplanes in a video game called Minecraft, which is pretty hard to do!  I can also make replicas out of Legos.

I can sew some basic , but fashionable collars for my two little kittens, Rocket and Soxs.   They look awesome and they are comfortable to wear, so that the kittens don’t try to take them off or overheat in the Florida summers.

Those are my talents, so I hope you liked reading this and getting to know me better.

Johannes Kepler

Johannes Kepler was born 1571 in Weil Der Statd (Which was in the Holy Roman Empire).  When he was six his mom took him to see a comet and that’s what made him interested in astronomy.  He was also a mathematician.  His first book established his reputation and his skills in astronomy.  Then he started working with Tycho Brahe, Tycho was also an astronomer.  They worked together for around a year before Tycho died, then Kepler became his successor.  Kepler is now known for his three laws of planetary motion.  First is that planets have eliptical orbits around their sun, second is that a planet’s speed increases when it nears the sun and decelerates when it is farther from the sun (According to Britanica.com/kids, ” Kepler’s second law of planetary motion…a line between the sun and the planet sweeps equal areas in equal times”).   Third is “The square of an orbital period is proportinal to the semi-major axis of its orbit” or basically that if you know how long it takes the planet to orbit, then you can figure out it’s distance from it’s sun.   Kepler sent his books to important astronomers like Galileo.  He died in 1630 but his works are still remembered today.  He impacted history by inspiring Newton and creating a new way to do math which is calculus.

 

Pet Lizards

I will be talking on how to care for a bearded dragon.

First, a bearded dragon needs a sandy habitat, like it’s natural desert environment.  They are omnivores so they enjoy insects like meal worms as well as fresh greens such as lettuce.  They are very friendly animals and won’t ever bite you.  They also need a heat lamp to bask in because they are cold-blooded.  They live 15-20 years and make a great companion.  They originated in Australia and usually are a sandy color but have been selectively bred to be orange, red and yellow apart from their natural sandy color.

 

 

The Four Inventions I Learned About This Week

The Newspaper:  The newspaper is a way of showing news using a printing press.  The first newspaper was made in 1605 in Germany.  It was made because people had to spread news by carving words into blocks of stone.  Newspapers became popular because it was easier and less expensive to make then using blocks of stone.  It is not as popular now because of the internet.

The Telescope:  In the 1300’s, the first eyeglasses were made in Italy.  By the 1600’s, the Dutch were making lenses.  Hans Lippershey invented the telescope in 1608.  It was made so people could see into the sky and look at planets and stars.  It was very popular because we could see cosmic objects we couldn’t see with the naked eye which benefited people by improving our concept of astronomy.

William Gilbert:  Peregrinus did his first study of magnetism in 1269.  His work was mostly forgotten.  In 1581 Robert Norman discovered a magnetic dip (which is an angle made from Earth’s magnetic lines).  His studies intrigued William Gilbert.  Gilbert studied magnetic declination, which is the difference of true and magnetic north.  His studies made people interested and led to the discovery of electrical current.  Von Guericke then studied electrical currents which led to a whole new age of discovery.

Compound Microscope:  Lense making spread to the low countries (Belgium, Netherlands and Luxemburg) in the 1500’s from Italy.  Compound microscopes use multiple lenses to produce magnification.  Compound microscopes can generate 1000+ times the magnification than a naked eye.  It is not known who the inventor is but some suspect Zacharias Janssen.  You can use the compound microscope to see things that are so tiny you can’t see with the naked eye.

My favorite invention is the newspaper because it led to the internet and that’s what im using to write this essay!

 

Alpacas

An alpaca (Vicugna pacos) is a domesticated South American camelid.   It is related to a llama and looks like a small llama.  A camelid is a even-toed animal, camels, llamas and alpacas all fit in this group.   Alpacas live in herds on the Andes and in Ecuador and Chile.  Alpacas are bred for the fiber in their hair unlike llamas which are bred to be work animals. Alpaca fiber is used in  blankets, gloves, hats and scarves.

The Back Staff

The back staff is a naval instrument that helps people pin-point where the sun is in the sky using the sun’s shadow.  It was made around 1585 by John Davis, he was a master mariner but he didn’t like having to use other tools were you had to look at the sun and damage your eyes.  Davis then problem solved and created a tool that could do the job.  The back staff is made so you don’t have to look into the sun, you put your back to the sun.  It is my favorite invention because me and my mom were lost at sea we could have used a back staff to find shore.
