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.
What is a Exponent?
A exponent is a small number that would be above a number for example a³ it is a short way of saying a x a x a. You can re-write a exponent as a whole number by multiplying the bottom number as many times as the number on the top in this case a x a x a. Using that question again lets say a is 5. you would do 5 x 5 witch is 25 then multiplying 25 by 5 to get 125.
What is the Difference Between Evaluating and Simplifying?
Evaluating is a term that is used in math books instead of the word solve. simplifying means to fix the question make the question your working with simpler so it is easier to solve, some places you might simplify are; multiplying fractions or making your final fraction smaller. The difference between evaluating and simplifying is large because they really are super different things. Solving a question and making it smaller are two different things, but i guess if i were to try to find a common ground between the two i would have to say with both your trying to solve the question.
Multiplication Law and why it works
The multiplication law is used for multiplying numbers with exponents, first you look to see if the bottom numbers are the same if they are you can continue. the law only works if the bottom numbers are the same. next look at the top numbers and add them together to get your final answer. the bottom stays the same. this law only works if the bottom two numbers are the same.
Division law and why it works
The division law is almost the same as the multiplication law. the bottom says the same, the only difference is you subtract the two exponents instead of the top. and again this only works if the bottom two numbers are the same.
Power of a power law and why it works
The power-law is a law that is used when you get a question like (4³)³ . in this case you need to multiply the 3 and the 3, the bottom number stays the same.
applications of exponents
Exponents are like fast/simpler ways of writing a number times itself __ times. instead of writing 3 x 3 x 3 you can write 3³. Exponents are used
one more thing i learned about exponents
I learned that there is no shortcut when adding and subtracting exponents ,you have to solve the exponent then work with that. Its annoying but its the only way to do it.

Other question (s): ______________________________________________________________________________
Student Reflections:
- Give three reasons why you would like this job (be specific):
- a) You can listen to music while you work, which would be nice for long days since it can help the time pass faster.
- b) You don’t really have to talk to anyone, other than a good morning or can you help me with ___?
- c) The job was easy to understand after awhile and was not too confusing.
- Give three reasons why you would not like this job (be specific):
- I don’t have much interest in phone wires so i feel it wouldn’t be a fulfilling job for me. I would always zone out or get distracted because I don’t have a real interest in what im doing.
- My dad’s work had this machine that makes a clicking noise all day and I was getting really annoyed at it, i feel if i worked there I would go crazy over the constant clicking.
- c) In ways yes, having to not talk to anyone is good. whoever I like to socialize so i think having little to no people would be bad for me because even if i just say something every little but hours upon hours of no contact seems agonizing.
- Is this job for you? Why or why not?
I don’t think the job is for me, like I said before, I don’t have much interest in the type of work my dad is doing so going to school just to do a job i have no interest in would leave me bored every day.However driving around all day was nice because you never had to sit still for long.
- Explain the value of the TOKTW experience in relation to your ideas about your post secondary (after high school) plans (education?, training?, travel?, work?).
I think this is a valuable experience and it did make me think about possible jobs i would want to do after high school, I had always been curious what exactly my dad did. I had a brief idea but I had always wanted to go with him for a day and just see what he did daily for 30 years. It also made me realize I want a job that i can stay at for years that will keep me preoccupied and interested in what im doing, my dad seemed so content with what he was doing so i can see how he did it for so long.
Final Reflection
All in all my day with my dad went better then a thought it would. In all honesty i though he would tell me to wait in the car well he did his jobs, but he exceeded my expectations and let me help sometimes. He talked to me a lot more then i though, he even tried to make jokes wich was not something he does much at home.His work was different then what i though it was. i was under the impression he fixed those big boxes on the side of the street ,he actually puts in or takes out jumper cables (?) in buildings. I had fun on the day with my dad and i wish i was feeling better that day, i felt nauseous and had a bad stumic ache all so i spaced out for most of the day witch i’m regretful about. If i ever get the opportunity again to go with my dad again i would %100 say yes because i wanted to enjoy it more then i was able to.
What I Learned About Grade 9 Fractions
What have i learned about grade 9 fractions? Well a lot! fractions are not exactly a strong suit of mine so i found this unit rather hard, but it taught me a lot to.
adding and subtracting fractions
In the past i had never quite figured out adding and subtracting fractions. For adding subtractions you look at the denominators. Are they the same? if they are you can simply add the top numbers together and keep the bottom number the same. Beside this is a photo of how i would add fractions with the same denominator.
However if the denominator is different there are more steps to getting your final answer. When i go to find the bottom number, i write down the number and then multiples of that number ( like 4,8,16,32 extra). and find when they overlap like how 4 and 8 meet at 16 then 16 is the new denominator for the answer. then you have to multiply the top number by what you had to multiply the bottom by. then add the wto together and you have your answer.
When subtracting fractions you can follow the same rules. seeing fi the bottom is the same and if it is then it stays the same. the only difference is that you subtract the top. if the bottom is different its the same steps but subtracting the top.
Dividing and Multiplying Fractions
I learned that you can convert division questions into multiplication questions wich is really helpful for me since division is also something i’m not great at.
for division i normally just convert them into multiplication questions no matter what because i don’t really understand the division questions. to convert a division question to a multiplication question all you have to do is flip the second fraction.from there you can simplify if the opportunity is there.
Putting Fractions on the Number Line
I learned how to put fractions on the number line which to me was surprisingly not as confusing as i remembered it to be. You look at the first hole number first is it positive? is it negative? in this example it is positive so it would be to the right of the number line. you should look at the hole number first in this example it is a 1 so your answer will be between 1 and 2 on the number line. Now your left with 3/4 the four represents how many spaces are between the 1 and 2 and the 3 represents how many of those ‘spaces’ that fraction is on the number line.
Comparing Fractions With Unlike Denominators
i learned that when Comparing fractions with unlike denominators you should convert them into common denominators if the answer isn’t clear like 
and 
. for me i like to draw it out in circles, even though that is the way you do it in elementary school i find it helps me more.
One other thing i learned/converting mixed numbers into fractions
This unit i learned how to convert mixed numbers into fractions, first you multiply the hole number by the denominator, then add the hole number to the top.
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.

To me my digital footprint is important because it stays worth me my hole life. Because it stays with you your hole life, nothing on the internet can really be deleted. When you go to get a job they look at that stuff, and mabye you thought you deleted that photo but your friends might have re posted it. Now an employer is looking at you fooling around acting silly, do you think they are going to chose you or someone with a clean footprint? I’d your applying for a scholarship they offen look at your social media,any inappropriate post or cyberbullying could stop you from getting the scholarship. 3 strategies for keeping your digital footprint safe: 1. Dont post anything inappropriate. This is a sorta simple step, if you wouldn’t show your parents then dont post it online. 2.Be nice. Dont comment negative things on others post, if your on Twitter I know it can be tempting to talk back to that person that insulted your fandom but by doing that your only starting negativity and Twitter fights wich is no fun. 3.Keep your private messages clean. They might have private in the name but that dosnt stop your friend from screenshotting your conversation.
If I could tell other students something I would tell them to be careful with the internet it is an amazing thing but it can also ruin people’s lives if they are not careful
