Power Information Fluency

By

Instructions;

I’m going to talk about Justin Trudeau and Dams. First of all, I will talk about what the is dam like. The dam is an information fluency with water. Dams were built for immersions and dimensions across mountain valleys and narrow lake. This is the way we use it in our lives, and dimensions are what we have to do in the event of a natural disaster. The dam also has water and embankment functions, and the lake formed by the dam is called a reservoir. Dams are useful in Canada, especially in BC, because we are placed in nearby oceans, and when it’s raining, it rains hard, and too much. We have harder weather and climates here, so we need dams in B.C. There are two examples of negative and positive hands. In Egypt, in Nile River, Egyptians are almost lost their heritages in the dam, but with citizens’ help, they saved their heritages. But in the other hand, they lost their nature. When it rained, soil erosion became severe, the resources supplied to the soil became wastewater, and all the untreated heritage sank into the water.

 

P1.

  1. What is the dam?
  2. What are the benefits of the dam?
  3. What are the issues of the dam?
  4. What are the other energy productions for an alternate?

P2.

  • What questions did you need to ask in order to research your topic?

I used these questions for my topic;

  1. What is the dam?
  2. What are the benefits of the dam?
  3. What are the issues of the dam?
  4. What are the other energy productions for an alternate?

 

  • What new or familiar digital tools did you try to use as you worked through this project?

I used a Korean blog to gather information. There were climates about Korea, so I changed into the Canadian climate.

  • What was the process you used to investigate the topic?

  • How did you verify and cite the information you found?

I searched from the official dam cites in Korea, and I found the facts and checked the blogs that were perfect to use in my assignments.

  • How did the process of completing this challenge go? What could you have done better?

I was challenged in understanding questions. The questions are quite complex for me, so I think I need to improve my scientific English more, and basic English.

safety story

By

There was a student whose name is Mark. He prepared his experiment about the change of the Candle. He put some fire on his candle. but he didn’t had the goggles because anyone noticed and remind him that he didn’t take his google. So he was go on without google, and his eye was hurt because of the smoke. And he just need to run to the eyewash station and wash his eye.

these are the symboles;

Health Hazard – anything that will give you breathing problems.

Flame – substances that are flammable and able to ignite from anything such as water or air.

Exclamation Mark – it causes immediate skin or eye damage.

Gas Cylinder – harmful gasses that are put in pressurized containers.

Exploding Bomb – anything at a high risk to explode.

Skull and Cross bone – poisons, or very harmful acids.

Environmental Hazard – chemical harmful to aquatic life.

Flame Over Circle – use fire to burn longer or larger

Corrosive – can cause immediate damage to the human body and be dissolved by material.

 

 

I’ll Uproad the picture(sorry i cant find my drowings)

these are the locations of stations;

Fume Hood: Go out the room and take a right to room 201

Emergency Shower: Go out the room and take a right to room 201

Fire Alarm Pull:  Beside the stairs beside 209.

 

How things work? – Lithium ion battery

By

Part I

Form and Function (How does it work?): What are its main parts and what do the parts do?  How does it use or generate electricity?

I and my partner researched Lithium-Ion Battery. This battery is very useful in our life. because it’s used in many things that we use in electronics. The lithium-ion battery has four mediums, those are Positive, Negative, electrolyte, and the Separate membrane. These are the most important thing in the lithium-ion battery. Firstly, Positive, which are Li and e, these are most important with your battery. Positive has Li(Lithium Ion), and E(electron). Li and E move to negative, which has C(Carbon), and it is the most important thing when you charge something. Negative, which has C(Carbon), it obtains Li and E and when we use batteries, it helps that Li and E to go out from Negative(C). For Electrolyte, it helps them(Positive & Negative) to move easily. Lastly, for the Separate membrane, it keeps them from meeting together. These are the top 4 ways for chemical reactions.

Part II

A) What are the strengths and weakness of your technology?

The strength of Lithium-Ion Battery is can make different shapes so that we can use it in different electronics. We can use Lithium-Ion Battery on a phone, a laptop, or the other things that need a different shape. However, this battery has a weakness, either. This battery has carbon in it, and when the whether is high-temperature, it can broke easily, so that the battery can be use much than before.

B) In your opinion, is it a satisfactory solution to the problem it is trying to solve?

If the carbon is thicker or harder than now, it can be solved.

 

 

 

And we made a model, which is description of Lithium – Ion battery and Normal battery

This is the model of Normal battery, for the right side, that is carbon, and the left side, that is aluminum.

This is the model of Lithium – Ion battery, for the reft side, it’s Cooper, and left side, it’s aluminum again.

A Fresh Look at The Periodic Table

By

I was teamed with Lorraine. our teamwork was really good, and I love my teammate. We did A, B, C, D, E, F, G, H, I did I, J, K, L, M, N, O and Lorraine did p, Q, R, S, T, U. We sorted out all the Alphabets, because we need to organized Alphabets it because our Periodic Table needs to look simple and organized. We decided square for whole shape, and yellow, blue, red, and purple. The advantages of our Periodic table are firstly, it’s simple, next, it’s easy to organizing what elements are in Periodic Table. Lastly, it’s very good to know what we did and what we think. When you see our Periodic Table, you would know that we worked hard and participated in our work.

we’d like to make our Periodic Table to looking simply. It tells us how much Elements are in there, and we tried to make it easy. also, we knew that we could do more. so we organized by vertically.

How much air particles in nature?

Experiment Project

You will be working with a partner to conduct an experiment over the next several weeks. You will hand in a lab write up written in paragraphs and including any charts necessary to answers the questions below. Your topic will include experimenting on how altering an abiotic factor (not alive) can influence a biotic (alive) factor. This topic must also relate to an environmental issue.  For example – 

How much organic waste can worms eat?

Can plants stop erosion?

How does acid rain affect fish?

You may create your own project our use one already created. This site has great ideas:

http://www.sciencebuddies.org/science-fair-projects/Intro-Environmental-Science.shtml

  1. Question, Research, Hypothesis Draft Due: 
  1. Create a question.

How much air particles in nature?

  1. Research the question.
  1. Predict an answer based on your research (hypothesis).

There will be less particles.

  1. Formulate explanations/reasons for your hypothesis. 

It because we (Rintaro and I) put pieces milk cartoons at near the road, park area, forest, and pond. So it will not have more than 25.

  1. Plan Draft Due:
  1. Plan an investigation. 
  2. Decide on your four locations. Good locations are: your back yard, your school, an industrial zone, a construction site, a park etc.
  3. Write the name of each location in your data table. Include the cross streets (Cedar and Sacramento Street), the address (1234 Maple Street) or the name of the location (Tilden Park or Valley Mall) in your table.
  4. Using your black permanent marker, draw a 1 inch by 1 inch box in the center of the white side (what used to be the inside of the carton) of each square.
  5. Write the name of the location on the bottom of each square, you will use three squares for each location.
  6. At each location, find a place to hang up three of your collection squares. You can hang the squares from a tree branch, sign post, light post, or any other safe landmark. If the location is busy with traffic, be sure to have an adult with you for safety.
  7. Before you hang each square up, spread a thin layer of vaseline in the black box in the center of each square with your finger. Hang up the collection square.
  8. Leave your collection squares for 3–5 days. It is best to leave them on days when there is no rain, so if you hear it is going to rain be sure to go and collect them even if you have not left them out for a full five days.
  9. After you have waited, it is time to collect your data from the squares.
  10. Revisit each location bringing your data table, magnifying glass and a digital camera.
  11. Remove the squares one at a time. Each time, use your magnifying glass to count the number of visible particles you see stuck in the Vaseline inside the boxed area. Write the number in your data table.
  12. Take a picture of the square. If your camera has a micro-setting for close ups, the pictures will turn out better.
  13. Proceed to the next square and/or location until you have collected all of your data and filled out your data table.
  14. For each location you will have collected three sets of data, so you will want to average the data to get a better result. First add together the three counts and write the answer in the “TOTAL” box. Then divide this number by 3 and write the answer in the “Average” box.
  15. Now you are ready to make a graph of your data. Make a bar graph by writing a scale for the number of particles on the left side (y-axis) and then by drawing a bar up to the correct number of particles for each location. Remember to label each bar of your graph, or make a color key.
  16. Print out your photos for your poster too.
  17. At which sites did you pick up the most particulate matter of the kind that is visible with the naked eye or a magnifying glass? Is this what you expected? Were each of your three counts the same or different? What do you think this tells you about the amount of this type of polluting particles in the air at each location?
  18. Do you think your data allows you to make global conclusions about the overall air quality of the sites you tested? Why or why not? Information in the Introduction can help you answer this question.
  1. What equipment will you use to collect and record data? (Digital technology, microscope etc.)

I’d like to use Vaseline, milk cartoon, rubber string, and Stapler.

  1. What safety concerns or risks are present? 

I think I need to be careful when I make a hole by stapler.

  1. Address ethical, cultural and/or environmental issues. Consider First Peoples perspectives and knowledge gained from other subject areas.

…Conduct experiment…

  1. Data Draft Due: 
  1. Construct visuals – graphs, models and/or diagrams to represent the data you have collected A chart with your numbers and a graph of those numbers are common parts of your data. You must include the chart or alternative with your initial data collection and a graph or other representation of that data. The chart must be titled and have both axis labeled.

  1. Describe the relationship between the variables.

We could know that how much air particles in air, and we can talk how to solve this problems.

  1. Explain any inconsistencies you see.
  1. Conclude Draft Due: 
  1. Did your findings support your hypothesis?
  1. Formulate an evidence-based conclusion (should be in-step with scientific concepts).
  1. Are there alternative explanations and conclusions then the one you presented? 
  1. Evaluate the methods you used and the conditions of the experiment.
  1. What were the sources of error or uncertainty?
  2. Are there any confusing variables?
  3. Describe ways to improve your investigation and the quality of data.

What would be the effects if earth rotated the other direction?

By

If the earth abruptly changed its rotational direction, probably many things we see every day would be destroyed.The best differences are the sun rise. Sun would rise in the West to set in the East. Another difference is the winds. It will  around and blow from west to east at 30 degrees north and south of the equator. For the moon and stars, it would rise in the East to set in the West. This Earth would have different climates and weather changing. Also, Africa would have lots of trees, and desert would cover North America. The cold weather would suffer to Eastern Europe. And Cyanobacteria, a group of bacteria that produce oxygen by photosynthesis, bloomed where they never had before. And the Earth, every 24 hours, spinning by North Pole to South Pole.

I focussed on the Earth’s rotation, but I knew there will be lots of changing, because of the Earth’s rotation. I also though that Sun, Moon, and stars would rise by opposite site.
