Solution Fluency

Solution fluency 

 

1) Define: In our everyday life we are wasting power, which is causing us to have to make more power then we really need 

2) Discover: since more and more people are relying on energy to go to work, feed themselves and pretty much anything else we do in a day. Just think about it, most people wake up to an alarm every day. How is the alarm powered? Using energy, the first thing you do in a day involves energy. Now maybe (and I’m not sure how) you can wake yourself up at the same time every day without an alarm, normally you turn a light on once you wake up, and again that light is powered by electricity. You can’t really avoid energy which is why we need to find a way to use less and waste less. 

3) Dream: I think we should start with lights, I think to help us use less electricity we should build our houses with more windows and skylights, I also think are ceiling lights and lamps should be auto lights, that way if you leave the house that one light you forgot to turn off will automatically turn off. Not only will this save power it will make family’s power bills less expensive. I also think houses should be built on a more open floor plan so the lights we do have in our houses light up a larger area thus not needing as may lights running at the same time. For example your kitchen dining room and living room could be all together with ought walls in-between, so if you have a bright light in your kitchen you wont need another light in that area.

And about areas that use energy that arnt houses. Lot’s of people have come up with many amazing ways of saving energy, but most of these are never implemented, the main problem being money.  

4) Deliver: My idea is to make all our light’s auto, that way lights will only ever be on when they are needed. I think this will help because lots of times I forget to turn a light off when I go to school, and it only gets turned off when I get home. Let’s say that light was on for 8 hours, although that might only be $6 dollars of energy depended on your energy provider, but that money can be used to buy am meal or help someone in need. Leaving that light on also wastes energy. Some negativity’s to auto lights is that if you sit still the light might turn off, If the auto on off part of the light breaks, there might not be a way to turn said light back on or turn it off. 

5) Debrief: I believe this was a great experiment to help students become more aware of the problems our world is facing due to electricity and the problems it can cause. Although I had no partner for this project I enjoyed researching about energy because l learned some things to. 

Bismuth

 

My Questions: Where is bismuth found?

 

What is bismuth used for? 

 

What temperature does bismuth melt at?

 

How do you make bismuth crystals?

 

Where does bismuth originate?

 

Is bismuth reactive?

Information: Bismuth is a silvery-pink tinted metal with the atomic number of 83, it was discovered in approximately 1500. atomic number= 83 Atomic symbol= Bi Atomic weight= 208.98040 Density: 9.79 grams per cubic centimeter Melting point: 520.53 degrees Fahrenheit Boiling point: 1,564 F Form at room temperature: solid

Element history

In 1753, French chemist Claude Geoffroy the Younger discovered bismuth.

If precisely 100 grams of bismuth had been on earth at the beginning of the universe 14 billion years ago, about 99.9999999 grams of it would still be around today.

Element features

  • Compared to other metals, bismuth resists being magnetized and is repelled by a magnetic field the most.
  • It has a very low thermal conductivity, lower than any other metal except mercury.
  • Bismuth burns with a blue flame and clouds of yellow oxide when heated.
  • Bismuth crystals are easy to make at home.

Reflection: 1) What questions did you need to research your topic? Well first i had to ask ‘what is bismuth?’ after that the questions became more specific like ‘at what temperature does bismuth boil?’.

2) What new or familiar digital tools did you try to use as you worked through this project? I was using goggle but not finding specifics or ‘interesting’ facts. but i remembered a video i saw before witch i had found really interesting. NileRed’s video called ‘Making metal cyristals from pepto-bisol’ reminded me that pepto bismol contained bismuth.

3) What was the process you used to investigate this topic? first i looked up my element and read through some articles, after that i stared compiling it into a document.

4) How did you verify and cite the information you found? for me i saw patterns in what the sites were saying, after awhile sites started saying the same thing.

5) How did the process of completing this challenge go? What could you have done better? The process of this project was fun for me! i was interested in bismuth so learning about it was fun for me. I feel that if i had started this sooner i could have put a lot more effort into it.
