Wonder: Why are planets in our solar system made of different material 

Obviously we don’t know the exact answer to the question, but we have a pretty good idea. Firstly when our solar system was being form their was these clouds called molecular clouds that were made of mainly hydrogen and dust. These clouds started to spin really fast, concentrating most of the material in the middle. These material started to form rocks and metal and started to warm up. This soon became the sun and when it was “born” it still collected more material. Then the ice, other rocks and other material started to form the inner planets like mars and earth. Eventually the sun had to get rid of the excess material so it released it in these this called solar winds and it push these material, gas and the atmosphere from the inner planets to the outer planets. These planets were mainly formed from the hydrogen and helium from the sun and the ice that couldn’t go to close to the sun or it would melt. The outer planets started to grow with the solar winds and the atmosphere which had hydrogen and helium into it and it had a higher gravitational pull with pull the materials out to them which also made them bigger then the inner planets. So that is one explanation to the question Why are planets in our solar system made of different material.

Biotechnology and Genetics Blog Post

ethans2016 on

Transgenic animals are when one animal carries a different gene from another animal.  This procedure has only really been done on mice and the first successful one was done on a mouse. There are three ways of producing transgenic animals, one is called DNA microinjection. This is when you transfer of a desired gene construct from a member of the same species or from a different species into the pronucleus of a reproductive cell. Then, you take the manipulated cell and transfer it to the recipient female after it is cultured in vitro. The second way is called Retrovirus-Mediated Gene transfer which is when retrovirus used as vectors to transfer genetic material into the host cell resulting in a chimera, then the chimeras are inbred for as many as 20 generations until homozygous. The final method is called Embryonic Stem Cell-Mediated Gene Transfer, this is when you isolate stem cells form embryos and the desired genes are inserted into these cells and then the cells that contain the desired DNA are incorporated into the host embryo. Some advancements are agriculturally, medical and industrial. Agriculturally, transgenic cows are made that produce more milk and milk with less lactose and cholesterol. Pigs that have more meat with them and sheep’s that grow more wool. Medically, products such as insulin, growth hormones and blood anti-clotting factors may soon be or are obtained from cows, sheep’s or goats. Industrially, two scientists at Nexia Biotechnologies in Canada spliced spider’s genes in cells of goats. The goats started producing milk along with silk strands. Those silk stands where used for creating light, tough, flexible materials in military uniforms, tennis rackets etc. Transgenic animals have changed the world by having the ability to have genes from one animal to another animal to in the case of cows produce more milk and in other cases helping advances medical studies and sciences and in many other different fields of study.

My Graduation Requirements

ethans2016 on

On your blog, you will do a post demonstrating your understanding of the requirements for graduation.
Replace the blank lines (with instructions) with the appropriate information.
You can use the PowerPoint and document I showed you earlier in the semester to find this information. It is in the password area of the blog.
Reminder: Course credits are only earned on classes that are Grade 10 level and up. You only earn credits if you pass the course.
• Title: My Graduation Plan
• Category: Planning 10

Fill in the info below, then copy and paste it into the body of your blog post:
1. Healthy Living
a. This year, I am playing hockey, soccer and baseball inside and out of school and I’m also in PE 10 to meet DPA requirements (150 mins/week of moderate to vigorous physical activity).
b. Next year, I will continue to play hockey, soccer and baseball and I will also take PE 11 to meet DPA requirements.
c. Other than physical activity, I will also need a concrete plan for healthy eating, stress management and physical activity in order to lead a healthy life after graduation.

2. Course Credits
a. I need 80 credits to graduate. A typical course is worth 4 credits.
i. 48 of them must be from required courses.
ii. 28 of them must be from electives.
iii. 16 of them must be from Grade 12 courses.
b. At the end of this year, I will have 40 credits.

3. Community Connections
a. I need 30 hours of work/volunteer experience. To show I completed this, I must show proof in the form of a pay stub or reference letter.
b. I can start accumulating these hours in Grade 10.
c. My plan to earn work/volunteer hours is through getting a job soon and volunteering at the rink downtown.
d. I will also need to complete a reflection that includes what you did, how you benefitted from this experience, and what skills you developed while volunteering or working. It will be 200 typed words minimum.

4. Career and Life
a. In addition to updating my resume, I will also create post-secondary plans and a financial plan to show that I have a plan in place after graduation.
b. When I graduate, my current plan is to get a part time job and go to college and then university .
5.
a. To prepare for the interview, I can look at the questions ahead of time. They are found on the GT website.
b. My interview will be with a riverside staff member (my rap teacher).
6. The 3 people at Riverside who are here to help with this process are:
a. Mr.Ahmelich
b. Ms.Chapell
c. My counsellor

In Grade 12, I will find all the necessary documents AND submit them on the GT website.
I will complete Grad Transitions 12 whenever I have English 12. If I have it in 1st semester, I must complete everything except the interview before the sale of winter ball tickets In 2nd semester, everything except the interview must be completed before the end of April

Workplace Safety

ethans2016 on

Three things I will do to stay safe at work is, ask questions if I don’t know something. If the workplace is unsafe then inform my employer/ supervisor and stay away from unmarked chemicals. Two things I will do to keep others safe is help them with anything their unsure about and keep the workplace safe and clean

Mattew’s story resonates with me the most but my dad is a chef and I couldn’t imagine him having a serious accident at work. I learn that every has the right to safe work and not to be afraid of speaking up and hopefully prevent a injury for you or another coworker
