Principles of Learning

-Learning involves patience and time
This connects to what we have learned because with a lot of the experiments and labs we have done they take patience and time. They have taken up a whole class or a few days to complete. They took this long because we needed to wait for results. This also relates to the inquiry experiment I am currently doing. My partner and I are growing tomato plants; each day we have been recording data and seeing if the ones with fertilizer grows fast than the ones without. This idea relates to the song because she wants to go out and explore however, she doesn’t know the dangers of what could happen to her. Moana doesn’t know how to sail a boat and learning takes time and practice.
-Learning involves recognizing that some knowledge is sacred and only shared with permission and/or in certain situations
When doing experiments, we can’t always follow rules. Scientists have discovered so many things because they have been creative. It relates because they didn’t have any knowledge. Or maybe some scientists have information that they will not give out because it is very significant. They want to be the only ones with the data. The quote is connected with the song because the song is about her wanting to go out there but her father won’t let he because he doesn’t want her to know what’s out there. The dad wants her to be the next leader of the island and doesn’t want the people of the island to want to move to possibly a better one.

Overall, I think this song has one very important message but the main one isn’t the one I am connecting these thoughts too. It is the secondary one which is the father doesn’t want her to go because he wants her to stay but she also doesn’t know how dangerous it is to go out there. Also, the dad knows how dangerous it is because he had sent men out before and they never returned so he doesn’t want his daughter to be in harm.

Technology and Genetics: Grafting

Watch video 1 first and 2 second.

1. What problem is your topic trying to solve?
-Increase crops. To repair broken parts. Heal faster.

2. What assumptions are made by your sources?
-Some say it is unnatural and shouldn’t be allowed but majority say it’s a good idea because it can prevent diseases.

3. What are the writers’ biases?
-One website I looked at was a greenhouse site and they were very positive about the process. Some other sites like the one written by people not so educated were both-sided.

4. What social implications does your topic have?
-If plants can be rehabilitated they keep producing oxygen.

5. What ethical implications does your topic have?
-Some people believe humans should only be able to do so much before they go to far. Cloning and grafting plants is up to nature to help.
-For skin grafting people have similar opinions. It is a good idea but is it to far? Some believe if you get injured your body should be able to repair itself.

6. Evaluate your topic and whether it is a satisfactory solution to the problem, given the weaknesses you have already addressed.
-I think it is a good solution because we can keep species healthier for longer and save them.

7. What is your personal stance on this topic?
-I think it is a good idea because it can help prevent plants from dyeing off. It also helps people with health issues like having troubles breathing. If a veins are clogged they can mend two veins together and then it will clean out.


Bloom Syndrome Mutation Story

Hi I am a gene but I’m not just any ordinary gene, I am unique. What makes me different is I have a special mutation called Bloom Syndrome. I’ll tell you about how I got to where I am while I take you on a trip down memory lane. It all started when my host’s parents had initial contact. Both of their chromosomes crossed over but a mutation started forming in the BLM gene. This leaded to mutated DNA helicase proteins because the BLM gene’s job is to provide instructions on making protein. When this happened the cells went through genomic instability which means a high frequency of mutation. When my host was born she was under the average weight. As she started mumbling and talking her voice was very high pitched. As she grew up her parent’s noticed she was much shorter compared to the other kids. She also had to wear plenty of clothing to cover her up because when her skin got exposed to sun, rashes would start to form. Her first day of school was great as the kids did not noticed anything different about her but as she moved up grades kids started noticing differences about her. They started making fun of her and wouldn’t let her play.

Writing this story went pretty smooth however I found there wasn’t enough information about my topic to make my story really detailed. I probably could’ve gone to more websites but with the due date close I did not have enough time.

Asexual Reproduction Lesson 1

1. Find real examples of your form of asexual reproduction
• A bud swells on a plant stem
• Plants gets planted, start to grow, fully mature

2. Describe the process
Buds expand due to tissue growth, eventually develops into mature leaves and or floral structures.

3. Define asexual reproduction in less than 10 words
-One organism that reproduces when an offspring occurs.

How Things Work: Nuclear Power Plant Model

Going into this project I was very excited because I love building and putting together posters and models. I find making a physical copy of something makes it easier and more fun to learn about.

Nuclear 3D Model Questions

1. The first main part is the reactor core. It consists of fuel elements, control rod, coolant, moderator and pressure vessels. The second main part is the reflector. This is placed around the core to reflect some of the neutrons that leak from the cores surface. The third main part is the control rods. This absorbs the neutrons so it can maintain or stop a reaction. Helps shut down the reactor in emergency situations. Free neutrons hit a uranium atom and split it. Nuclear energy starts from splitting of the uranium atom. This is called fission; it generates heat to produce steam which is used by a turbine. Because they do not burn fuel they do not produce greenhouse gas emissions. Which is better for the environment.

2. Dangers: Although nuclear power plants are one of the less harmful energy sources it is still very harmful. When you enrich uranium it harms the environment. If a serious accident occurred large amounts of dangerous radiation which can cause an increased risk of cancer to people that are exposed. It does not emit air pollution, isolates its waste from the environment and does not require a huge amount of land.

3. Ethical Implications: Nuclear power plants are defiantly a more efficient way of producing electricity however it can be very harmful to the environment. If the uranium fuel were to leak it can cause many health issues such as loss of breath, illness and if touched by heat could blow up.

4. Environmental Implications: Nuclear power plants are one of the cleanest forms of energy as it does not emit air pollution. However, uranium is radioactive so if it were to some how leak out it could kill of people and animals in our world.

From the beginning of this project I felt very comfortable and confident about the collaboration as we got to choose our partners. This made it easier because we already knew how our partners worked and we didn’t need to take time to see how each other work we could get started right away. If we were to do this all over again I think we should’ve researched first and then started throwing out ideas of how to build the model. This way we knew every detail of the machine. Building the project everything went smoothly we each did an equal amount of work so I think splitting up the tasks evenly we did a good job. Overall I think our model turned out great but if we got more time it would of allowed us to make it bigger and better by maybe adding more details and explaining each part and how it works in the process of making electricity.

Science App Review

Dream: I would like to find an app that lets me to science experiments at home without me having to get the actual supplies I need. But I also want to learn about the materials I amusing so hopefully there will be some facts.

The app I chose to use is Kids Science Games by Ehtasham Haq. I found this game very user friendly as it is not to busy or hard to figure out. The games were fun and easy to follow along with. However, the app was a bit glitchy and touchy at times so I think some people would get frustrated by that. While I was doing the experiments educational facts would pop up which told me why I was using something and what it does.
I thought this was great because it is a game parents can give this to their kids to play and they would be learning at the same time. But for grade 9 students I think it’s a bit to colourful and cartoonish. The experiments could have had more steps for an older age group. What I think would make the app better is by adding age groups so they can have for simple games for younger kids and more complicated experiments for older users.
This app would also be great for people that don’t have all the supplies at home that they need to complete labs. The app covers a range of subjects like chemistry, physics and electricity.
Overall I thought the app was interesting and well designed but not for an older age group.
