Astronomy and the Future of our Earth
Should the Human race be worried in our Future?
In this video with Martin Rees talks about "Our Final Century" and discusses the immense worry of the future outside the bible belt and how we should rather look to academics for answers rather than our government for answers on how the Earth can be affected by astronomy in our future.
Researchers say that our sun will have a life of four and a half billion years and another 6 billion before fuel runs out and life is vaporized.
Rees states " It will not be humans that witness the end and experience it but creatures from us out of bacteria." Out of fifty years 100th of 100 millionths of the Earths age that the amount of carbon dioxide has immensely risen, radar transmissions such as radio waves from objects such as televisions and cell phones will effect our future. Due to metallic objects escaping into our orbits around our Earth and how extraterrestrials predict the final doom in six billion years. Also that post-human life is elsewhere that we are in the third universe and the fourth universe is out there somewhere.
Based on the article by Dr. Sten Odenwald, the article is a pattern of what economists, astronomers, and researchers have come up with explaining on what they believe will happen in our future.
This article supposedly is what they think what should happen to Earth and humans in our future. So by 15 million is predicted the end of eternity and that all humanity has been died out. By 100 million the universe is to remain hospitable to life. As these factors are pointed out it is also similar to what Rees has mentioned in his article.
Another mystery is how the Milky way will also hold the key to future life of the planet Earth. This article is a comparison to how Rees mentions our biological history.
" This galactic activity leaves radiation resulting in causing dangerous cosmic arrays. With higher rates of genetic mutations in our organisms interfering with their ability to repair damaged DNA. Researchers believe this destructive activity could lead to development of new species while terminating others." This is a cycle that never stops.
In conclusion, the pattern of how the Earth can be affected by our universe is looking back in history and also following important events such as the Ice Age, Dinosaurs, that is all extinct now but their bacteria is what allowed humanity to be created. This life cycle is never-ending. The universe remains a mystery to researchers as well as how the Earth will be affected in our future.

Volcanoism
Patterns-densely follows the west coast of the Americas. Sparsely, throughout the Pacific,Americas, continues down the Eastern side of Asia, very dense from Russia down to Japan, through Malaysia and Polynesia.
Observations- Islands arise as geothermal activity pushes material up from the inside of the Earth. Strings of volcanoes follow the tectonic plate boundaries.
Geography
There is greater geographic variation following the tectonic plate boundaries. There is an overall greater altitude near the north and south poles.
The interaction of the plates creates a variety of geographic features. Ocean trenches often follow land masses. This is because the area where oceanic plates are subducted beneath the continental plates usually.
Geochronology
Running all along the Mid-ocean ridge you can see that it has the youngest volcano because new oceanic plate is coming up.
Seismology- follows tectonic boundaries, the ring of fire has the greatest depth of earthquakes.
Pacific Plate
Volcanism follows the edges with great density. Island chains are evidence of tectonic movement and direction of movement,it is like a scar. i.e. Hawaii.
The plate generally seems to be rotating counter clockwise. The Pacific is diverging from the Nazca plate, causing emergence of young sea floor.
The boundary following the North America continent is transforming, creating the San Andreas fault and causing a lot of shallow seismographic activity. On the Asian side of the plate is subducting and creating the Java/Figi trenches. On this side there is alot of deep seismographic activity.

Bias group project
Sept 3, 1921. Mr. Lawrence Efeter Sr. purchased a new 1921 Cadillac from Hollywood Cadillac Co. for $3885.00. This was a gift for his son whom was a hot, rich guy from Santa Monica that just finished law school. Mr. Efter after practicing for 9 years decided to settle down.
May 28,1930 Mr. Lawrence Efeter Jr. purchased a wedding ring for $575.00at Broadway Diamond Company. He is no longer on the market “Shucks”.
To surprise his wife for a wedding gift on June 20, 1931 Mr. Efeter put a down payment of $450.00 on new house in Hollywood.
December 19, 1903, Lawrence Jr. celebrated a birthday so Mr. Efeter Sr. went down to California Toyland Co. and spent $83.20 on his birthday present. This was a memorable experience for Mr. Efeter.
Sept 7, 1921 Lawrence Jr. was trying to show off to his buddies and wrecked his car where he had to spend $288.76. Mr. Efeter Sr. was very disappointed when he had to spend his money on the repairs at Wilshire Auto Repair Service.
June 20, 1931 . On the same day Lawrence purchased his wedding ring he decided to invest in Walker & Walker and paid $700 to become a partner in the firm to secure his family’s future.
June 22,1926. Mr, Efeter Sr. pays University Club Florists $312.75 for flowers for the funeral services for his wife. Lawrence Jr. was very devastated for the loss of his mom he spent most of his income at the strip club.
December 1, 1927 Lawrence Jr. decided to purchase $750.00 on lingerie for the strippers he met as a payment for services. He purchased this lingerie at Anita’s Lingerie Salon which was the most expensive salon.
July 5, 1931, Lawrence Sr. got a call from the police stating his son was shot by his wife, come to find out she was upset with Jr. because she found out all the women he was sleeping with. Mr. Lawrence Sr. pays Hollywood Hospital $100 to get the bullet removed from his son.

Water Turbine
The created model I decided to use for our group project on the water turbine. This designs objectives is to explain how the turbine operates, observe its principles, and determine the speed of the turbine. The water turbine works based off the direct pressure of water moving against the wheel, which makes the wheel rotate. In this project the effects of the turbine include height, diameter, force, and momentum that produces its energy. Along with the other groups projects goes into more depth my project discusses a few important factors to coincide with the others projects as well
The following supplies that were used for this project are:
ballpoint pen tube
washtub
duct tape
hose
hammer
nail
newton scale
non-toxic water glue
notebook
washer
plastic cups (6-5oz.)
plastic plates (3-6" diameter)
plastic bowl
scissors
stop watch
wire coat hanger (16")
wire cutters
wood block (3x6x1 with a hole drilled through it)
string (50')
The definitions listed apply to the procedure of how the project works:
energy- capacity to do work
force- amount of energy exerted on an object
hydroelectricity- electricity generated by turbines that are powered by water
hypothesis- an educated guess based on scientific evidence and tested for accuracy using scientific methods
joule- a unit of work or energy equal to the work done by a force of one newton acting through a distance of one meter
newton- the unit of force in the meter-kilogram-second system equal to the force required to cause an acceleration of one meter per second per second to a mass of one kilogram
turbine- a machine in which the kinetic energy of water or gas is converted to mechanical energy as the fluid reacts to a series of paddles, vanes, etc. arranged in a wheel
variable- a part of a process that changes depending on the situation
vertical- perpendicular to the horizon
water wheel- a wheel driven by falling or moving water and used to power machinery
watt- work done at the rate of one joule per second
During the experiment tests were created to measure the speed of the turbine. In order to do this a speed measuring device was created. With the string of 50' the measurement of the amount of string from the string guide to the side of the washtub. Subtracting this amount from the original 50'. This is the number used to calculate the approximate speed of the turbine 600 inches - 12 inches = 588 inches.
Turbine Speed
To determine the speed of the turbine. Speed is the distance an object travels per unit of time (D/t). To calculate the approximate speed of the turbine, I divided the length of the string by the time ( seconds) it takes to rewind the string onto the collector. Three trials were repeated and the following are the average results of the turbine when placed with a hose (43 inches) under the faucet in the washtub.
Trial 1 15.84 seconds
Trial 2 16.00 seconds
Trial 3 14.41 seconds
Average speed of all 3 trials= 38.22 seconds
To hypothesize how the speed of the turbine is affected by raising the height and placed directly under the faucet and water pressure completely turned on with the washtub 3 feet under the sink.
Variable Effect
Trial 1 37.06 seconds
Trial 2 37.66 seconds
Trial 3 36.97 seconds
Average speed of all 3 trials = 15.79 seconds
Determining the watts the turbine generated I measured the length of string 588 inches.
Operated the turbine so the collector takes up the string. It took 17.56 seconds to rewind the string.
When connecting the newton scale to the mass (washer) and dragged it across the floor it took 0.5 newtons of force to move the mass.
The work done by the turbine I multiplied the force/ newtons(N) by the distance/meters(M) to find the mass traveled.294(joules)J.
The definition of the watt is the amount of work(J) divided by the time(seconds) it takes to do the work(J/sec.) To calculate how many watts of power the turbine can generate. Dividing the amount of work (J) by the time (seconds) that it took to rewind the string on the collector watts . The first trial was 7.69 watts and the second trial was 18.62 watts.
The difference of the heights in each trial were effected due to the fact that the greater the distance in height between the water in the bucket and the end of the hose, the greater the pressure will be. For example if a rock is dropped from high above will it hurt more than down below? The answer will be it will hurt more below because of the force. So there is greater force at the bottom of the hose.

Water Turbine Project
Topic: Forces and Newtons Laws
Understand and apply the relationship between force, mass and acceleration.
F=ma
Acceleration is applied through force. Mass is the turbine. The force acting upon it is the water flowing that causes acceleration. So the greater amount or weight of water on the mass, the greater the acceleration. Acceleration depends on force and the distance force moves the water.
Topic: Velocity and Momentum
Explain real life phenomonon in terms of v and m.
p=mv
The greater amount of water hitting the wheel the higher the speed and the faster it will move. The less quantity of water will decrease momentum. Velocity is the speed and direction applied to how the water will be hitting the turbine will give it a certain momentum depending on the mass. The velocity of the water hitting the blades which will create a certain momentum. The greater the mass will create less velocity due to their inverse relationship. A water turbine and how it works is an example of a real life phenomonon in terms of v and m.
Anita worked on a paper model of a fan with construction paper, paper cup, and nail ...The pictures posted will show examples. Over the weekend i will come up with another design to give us more ideas for our project.

Baloney Detection Kit & Harwood Model
In science, we always depend on experimental results, data, observation, measurements, and facts. The Harwood Model contains nine activities in which scientists engage throughout the scientific process. In science new ideas are considered and to rule out skepticism. In order to do this scientists are equipped with the Baloney Detection kit as a tool. This tool implies steps to avoid logical and rhetorical fallacies while the Harwood model implies a tool to provide framework for structured, guided, open inquiry lessons to explain the scientific process. The two models both use activities in a similar approach as far as asking questions to determine the difference between science and pseudoscience and to determine the range of probability between true and not true.

As a human being learning new paradigms .. What mode of skepticism are younger kids being taught when in the 21st century children are being introduced to a drug culture rather than embracing an opportunity to learn without this fictional epidemic?
2. Educator
How will education in its new paradigm teach and prepare young students to live and work in an increasingly complex and challanging dynamic global world.Will information seeking, analysis, ability to reason, problem-solving, teamwork,peer-teaching, crativity, resourcefullness, ability to adjust change be incorporated in the 21st century?
3. Scientist
How can we integrate Globalization, Humanization, and Futurization into our three dimensions of the universe: time, space, matter/energy and their relationship with holistic higher education. How can we expand its focus to that way students are equipped to operate both visual and virtual reality?
