Climate in Canada

Adib on

— Heartland —

 

Effects of a warming climate:

The warming climate in the ‘Heartland’ brought out great impacts, changing the region’s biodiversity, ecosystems, and way of living. Warming climates have led to extreme weather events such as heavy rainfall which leads to floods and natural disasters. Biodiversity has been degrading due to being exposed to weather conditions that may not be typical for wildlife. Heatwaves have also been increased which may be problematic for certain species who may not have endurance for such weather. Climate change also causes biodiversity to be shifting toward the north, declining the population of animals in this region. A big part of Quebec and Ontario which is agriculture and forestry, has also been affected as crop cycles are disrupted.

 

Causes of a warming climate:

The causes of a warming climate in this reason can differ for many reasons including human, and natural causes. Greenhouse gas being emitted plays a role in climate change which is mainly carbon dioxide (CO2). Burning fossil fuels such as natural gas, oil, and coal releases large amounts of CO2 into the atmosphere, which is gradually causing the climate to change. Besides human activity, natural occurrences such as volcanic eruptions and the earth’s orbit around the sun can cause changes in specific areas in the world. The facts listed above show the problem of greenhouse gas being emitted and how much they can cause changes in the climate.

Modeling Mitosis

Adib on

 

Interphase: During interphase which is the longest stage, the cell carries out its normal functions like growth and DNA duplication in preparation for mitosis.

 

 

Prophase: The first stage of mitosis. It is when the nucleolus starts to dissolve and disappear, which then allows chromosomes to move freely. Spindle fibers also form within the cell.

 

 

Metaphase: The second stage of mitosis. it is when the chromosomes align in the middle of the cell.

 

 

Anaphase: The third stage of mitosis. It is when the centromere holding the sister chromosomes split, separating them into single chromosomes.

 

 

 

Telophase: The fourth stage of mitosis. It is when the chromosomes reach the sides of the cell and spindle fibers disappear. 2 nuclear membranes then form.

 

 

 

Cytokinesis: The final stage of mitosis: It is when the cell divides in two.

Edible DNA Lab

What is DNA: DNA is a molecule that has the genetic information needed for the development and function of living organisms. DNA is made out of 4 nucleotides such as adenine (A), guanine (G), cytosine (C), and thymine (T). These nucleotides are arranged in a certain order to determine the functions of an organism. DNA has two strands of nucleotides that are twisted around each other to make a double helix. Hydrogen connects the nucleotides on one strand to their matches on the other strand. Adenine and thymine (A-T) and guanine and cytosine (G-C) are pairs.

What does DNA do: DNA has the genetic information that controls the development and function of an organism. It provides information for the cells of an organism such as eye color, height, hair color, etc. DNA also plays a role in cell division, which happens during mitosis. DNA gives cells information needed to develop an organism.

How easily does DNA copy itself: DNA replicates itself when the cell unwinds the DNA molecule and uses each strand as something to build another strand. It is a very accurate process, that almost can never fail.

What questions do I have: -Why do DNA defects take place? -How many DNA cells are in our bodies?

Answers I found to my questions: -DNA defects usually happen due to abnormal chromosomes. -The human body has 3.2 billion DNA cells

 

 

 

 

 

 

 

 

Connections-based Learning — Proposal Post

Adib on

 

CoDesign: The person we connected with is Saul Mwame, who runs a beekeeping business named “Haven Bees”. He currently runs his beekeeping business in Tanzania, but he is yet to run it internationally. Something that interested me about the connection with Saul, would be his determination to do good for his country. He appeared on a broadcast for the UN explaining his plan to improve education for students in Africa. Additionally, Saul presented himself to our class on the Zoom call, and I felt interested in his goal for beekeeping and wondered how our class can help him out. However, a problem I wanted to address about Saul’s business would be the lack of promotion internationally, which may be a challenge for him.

“Nothing can stop me but me. I dream that one day I will establish an aerospace university in my country”

CoOperate: After doing some research on a solution for the problem I addressed, I have found many things that would help Saul expand his business. Firstly, spreading the word to family, friends, and associates, about Saul’s business can be a great help. Social media could be very helpful in raising awareness, as it is accessible to many. Also, hosting workshops or events related to Saul’s beekeeping business can possibly make many want to support him. Lastly, encouraging Saul to sell his beekeeping products internationally could go very well if he is determined to do it.  

CoCreate: As I spent time brainstorming about a solution for the problem, I thought of a few things to promote Saul’s beekeeping business. One of them is to create posters with information about Haven Bees to display across the school. Another one was to use an Instagram account to promote Haven Bees. And lastly, I had an idea to make business cards for Haven Bees and distribute them to local businesses and/or markets that would possibly be interested. The one idea I decided to focus on was making an Instagram account with a group to promote Haven Bees. For this, I would need the skill of teamwork, working with a group that is assigned different tasks. As for materials, all I need is a device which is capable of doing research and posting on social media.

Commemorate: During the process of Connections-based learning, I was able to learn based on my interests, ideas, and experiences, which was one of the things I enjoyed most about the assignment. The process of making connections allowed me to expand my understanding of topics much better. Overall, I think this was a great experience because it allowed me to develop meaningful connections with my learning. As for the process of my post, I think the quality of it is good because I worked hard to add a good amount of information about everything I’ve done and gained knowledge about in this assignment. Lastly, one thing I could’ve improved on would be the quality of the Instagram account to promote Saul’s business. Me and my group could’ve done better with the design and organization of the account, as well as managing it. I’ll keep it in mind to work on these things harder next time.

Fictional Science Safety Story

Adib on

Adib H.

  1. (Safe) 

The lab was about to begin for my science class, and the teacher started giving us test tubes to mix our liquids, and a test tube rack to hold the test tubes safely. I carefully placed the test tubes on the rack and poured in the liquids given to us without rushing to not cause any spills. I noticed the liquids had the ‘Flammable Material’ symbol, so I knew a fire could easily occur. After that, I saw my friend accidentally pour the chemicals all over himself, so I noticed that after people stayed calm and were guiding him to go under the ‘Safety Shower’ so that he could remove any harmful/dangerous substances on him. He stayed under the safety shower until the instructor gave him the signal that he was fine. And in the end, he was clean and safe from any chemical dangers, and he learned from his mistake to not repeat it again. 

 

  1. (Unsafe) 

I was about to begin another lab for my science class, and we were given Erlenmeyer Flasks to transport heat and store substances, and a funnel to make it safer and easier to pour the needed liquids. We were given the liquids needed to do the lab and I saw that one of them had the sign of an exploding bomb (meaning it was an exploding hazard), so I knew that we needed to be extra careful with that one substance. As we were transporting the liquids, I noticed my friend Bob being reckless and unsafe with moving them. I knew that if he kept it up, something bad was going to happen. But Bob, being an unsmart guy, uses a different liquid than what he was supposed to, and a huge flame rose. So instead of getting a fire extinguisher, he decides to pick it up by himself and put it in the sink. In the end, he burned his hand and learned his lesson. 

 

What’s The Best Ways Beekeepers Can Help The Environment?

Adib on

Questions I have asked:

  • (Main Wonder Question): What are The Best Ways Beekeepers Can Help The Environment?
  • How does beekeeping affect the effect/help the environment?
  • What are things harmful to bees?
  • How can we help bees survive?
  • How can beekeepers increase/improve the production of honey?

Digital tools I have used:

  • Google
  • YouTube
  • Pexels.com
  • Citation Machine
  • Gale Engage Learning

Summary:

Using sway was a little challenge at the start, since I wasn’t too familiar with the application, but after using it and putting down information it started to become easier for me. One thing I struggled with the most was getting the text in the right place I intended it to be for. Another one of my challenges while doing this assignment, was finding different information about my topics, so that’s why I couldn’t use too many search engines, or recourses. Overall, this assignment was good, but one thing I would change about it would be to use a different application I’m familiar with like, Power Point but either then that I think it was a good way to share my information.

I am now able to understand my question a lot better then before this presentation. think I asked some great sub questions that helped me get to the conclusion of understanding the question a lot better. I asked the question: “How does beekeeping affect the affect/help the environment?”, because I thought that it was important to know the benefits of bees/beekeepers and how much they help our environment to understand our question more fully. I also asked the question “How can we help bees survive?” Which I thought was a good question to connect to the main topic. Overall I learned a lot and I think I made it more clear what can be done for beekeepers to help the environment.
