Welcome to your Digital Portfolio at Riverside Secondary. Riverside provides a unique and innovative digital culture for all of their students to learn in. We are a 1:1 school which means each and every student and staff member uses a device to enhance teaching and learning, and most importantly, help prepare our students with tools and skills to be successful in the future. In order to ensure the success of the 1:1 program we have put in place a variety of support systems.
Our school uses Edublogs to document and showcase your learning and experiences at Riverside. You will use your blog to post work and assignments for classes, to post about your learning and experiences in your portfolio, and write reflections based on the Core Competencies.
Coquitlam Open Learning – Applications of Digital Literacy 10
Riverside is fortunate to be able to offer our grade 9’s a course credit for their work in the development of digital literacy skills. The course is called Applications of Digital Literacy and will be a grade 10 credit given to all our grade 9 students. In their classes, students will be required to demonstrate the ability to efficiently and effectively navigate digital technologies while behaving ethically, responsibly and protecting personal security and privacy.
Please take a look at Riverside’s Digital Literacies model.
A digital footprint is the collection of all the traces you leave in electronic environments as you use or move through them. Some is content you actively volunteer—like your Facebook profile. Other material is passive—the cookies a site stores in your browser, the content your district collects about your use of their equipment, etc. All this data can be aggregated to build a profile of you and your behavior.
Never post anything that you might find embarrassing later.
Be careful with the pictures you post on your public profiles. Remember others will see them and judge you based on their content.
Change the privacy settings on your social networking sites so that only your Friends can see your information
Do not disclose your personal address, phone number, passwords. Bank card numbers…etc even in private messages. There is always the possibility of somebody hacking into your account and finding them.
Do not post things to bully, hurt, blackmail, insult, or afflict any kind of harm on others
Always keep in mind that once information has been posted online, it can be almost impossible to remove because of archiving and file sharing. Even though you deactivate your accounts, the information may still be retrieved by others.
Besides we have other intelligent advanced creatures?
The first point of Fermi’s paradox, the scale problem, is an order of magnitude estimate: the Milky Way has about 250 billion (2.5 x 1011) stars, and the observable universe has 700 boundary (7 x 1022). Even though intelligent life appears in a planet around these stars with a small probability, there should be a considerable amount of civilization in the Milky Way alone. This is also in line with the principle of mediocrity, that is, the earth is not special, just a typical planet, with the same laws and phenomena as other stars. The Drake formula can support this argument.
The Drake equation is:
N = the number of civilizations in our galaxy with which communication might be possible (i.e. which are on our current past light cone);
fp = the fraction of those stars that have planets
ne = the average number of planets that can potentially support life per star that has planets
fl = the fraction of planets that could support life that actually develop life at some point
fi = the fraction of planets with life that actually go on to develop intelligent life (civilizations)
fc = the fraction of civilizations that develop a technology that releases detectable signs of their existence into space
L = the length of time for which such civilizations release detectable signals into space
Question: There are so many aliens that may exist why we didn’t see it?
The second point of Fermi’s paradox is the answer to the scale view:
considering the ability of intelligent life to overcome resource scarcity and the tendency to expand outward, any higher civilization is likely to find new resources and open up their star system. Then there is the galaxies involved in the neighborhood. Because after the birth of the universe 13.7 billion years ago, we did not find tangible and reliable evidence of the existence of other intelligent life in the earth or other parts of the observable universe; we can think that intelligent life is very rare, or our general behavior towards intelligent life. The understanding is wrong.
A Type II civilization—also called a stellar civilization—can harness the total energy of its planet’s parent star (the most popular hypothetical concept being the Dyson sphere—a device which would encompass the entire star and transfer its energy to the planet(s)).
A Dyson sphere is a hypothetical megastructure that completely encompasses a star and captures a large percentage of its power output. The concept is a thought experiment that attempts to explain how a spacefaring civilization would meet its energy requirements once those requirements exceed what can be generated from the home planet’s resources alone. Only a tiny fraction of a star’s energy emissions reach the surface of any orbiting planet. Building structures encircling a star would enable a civilization to harvest far more energy.
Question: 1.Now we are not found A Dyson sphere in the sun (stellar). So has them a Type I civilization ?
2.They are not in the Milky Way, so they can use the entire galaxy no need the sun?
Allan Hills 77005 (also known as Allan Hills A77005, ALHA77005, ALH77005 and ALH-77005 is a Martian meteorite that was found in the Allan Hills of Antarctica in 1977 by a Japanese National Institute of Polar Research mission team. Like other members of the group of SNCs (shergottite, nakhlite, chassignite), ALH-77005 is thought to be from Mars.In March 2019, researchers reported the possibility of biosignatures in this Martian meteorite based on its microtexture and morphology as detected with optical microscopy and FTIR-ATR microscopy, and on the detection of mineralized organic compounds, suggesting that microbial life could have existed on the planet Mars.
Allen Hills meteorite 84001 ( often abbreviated as ALH 84001 ), and transliterated as Alan Hills 84001, is an American Antarctic Search for Meteorites (ANSMET) The group discovered a meteorite on December 27, 1984 in the Allen Hills of Antarctica. Like other meteorites in the SNC group , ALH 84001 is also considered to be from Mars. In 1996, the meteorite was on the headlines of global news, when scientists announced that the meteorite might contain evidence of tiny fossils of Martian bacteria.
3.Wisdom creatures are self-destructive
In a short period of time before or after the development of radio or space flight technology, technological civilization may or may not self-destruct. Possible extinctions include nuclear warfare, biological weapons or accidental viral infections, nanotechnological catastrophe, irrational physics experiments, artificial intelligence that is out of control, Malthus disasters after the deterioration of the Earth’s biosphere, resource depletion or energy depletion, especially fossil energy Depletion leads to a retreat into a non-technical civilization. Such topics are discussed in both novels and mainstream scientific theories. Some people think that the end of mankind may come faster than expected. In 1966, Carl Sagan and Iosif Shklovsky proposed that technological civilization would either be self-destructive in the process of developing interstellar communications for a century, or master its own destiny and continue to survive for hundreds of millions of years. Self-destruction can also be examined from the point of view of thermodynamics: life is an ordered system that can maintain itself and fight against disorder; but “external transmission” or interstellar communication may be a turning point in the system becoming unstable and self-destructive. .
4.Alien civilization exists, but…
Due to the order of magnitude…
The time between civilizations is too far away to be easily accessible
Alien civilization has discovered human beings, but the signal sent back has not yet reached the earth.
Earth people have not noticed that the signal is a product of alien civilization.
The signals sent by the Earth have inadvertently destroyed the alien civilization.
Due to technical reasons…
Civilized technology may never effectively transcend galaxies
The way humans look for extraterrestrial life is not correct, so they have not seen it.
Technical civilization generally goes through technical singularities. Since then, human interaction with the singularity has not been possible, or meaningless.
Extraterrestrial technical phenomena are too close to natural phenomena to distinguish them.
Humans have identified many planets that can live. Other living conditions have been created. So the possibility of aliens is actually very large. Furthermore， if it is just us that look like waste lot of space. Aliens may exist, and large filtering theories may exist at the same time. This reminds me of the age of dinosaurs that lived on Earth earlier.
