Arielle's 2 Minutes To Make A Difference

Wednesday, May 20, 2009


This video is created by Michelle, Carrie, Sutchai, and I also known as "MACS." Our video shows the effects of poverty and how we can help prevent it. In other words, it shows how we can make a difference in the world today. I hope it influences you in a positive way to take some action. The credits go by really fast, but we had to do that because of the maximum time. Overall, I really enjoyed working on this project with MACS, putting our time, hard work and effort into it. I hope it sends out the message to you all! Please comment and tell us what you think. Enjoy our video (:

Cure For Harbeck's Amnesia

Sunday, February 22, 2009
Mr. Harbeck supposedly slipped on some ice, fell and bumped his head which caused him to forget what he was going to teach us. To help him regain his memory, we were assigned:



  • To explain the four artifacts
  • How These Words Relate: Legs, hypotenuse, R.A.T., Greek, and theorem.


Artifact #1:

The first artifact is known as a right triangle or a R.A.T. (right angle triangle). What makes this triangle a R.A.T. / right triangle, is the 90° right angle where the square on the bottom left corner is placed. The two sides that create this right angle are called legs. The other two angles are called theta and beta, together they equal to 90°, which makes them complementary angles. The longest side of the triangle or the side across from the right angle, is known as the hypotenuse. The hypotenuse is usually labelled as "C" and the legs are labelled as "A" and "B".








Artifact #2:


The second artifact is a square. The lines on each side of the square, are called lines of symmetry. This shows all the sides are equal to each other, making it a square and not a rectangle. In each of the four corners, are 90° right angles. Together, the whole square is 360° (4 x 90° = 360°). If you were to cut this square diagonally in half, you'd have two right triangles, like in the first artifact.




Artifact #3:

Who is this a sculpture of? Well he is a Greek man of brilliance. He is thought to be the 'Father of Math'. This man's name is Pythagoras and was a vegan (someone whom doesn't consume any animal products). He was a mathematician who loved music. Pythagoras was the first to figure out the circumference of the earth and proved that the earth revolves around the sun. He was very fluent in Egyptian and was interested in harmonics. He also invented the Pythagorean Theorem, a² + b² = c².















The Pythagorean Theorem is a formula or theory that can be proved. This theorem finds out the length of the side 'C' on a right triangle. To figure out the length of 'C', you need to know what sides 'A' and 'B' are. Next, you square 'A' and 'B' and add them together, this will leave you with 'C²'. Last but not least, you must find the square root of the number and that gives you the length of 'C'.


















Pythagorean Theorem Video Part One - Krissia, Carrie and I









Pythagorean Theorem Part Two - Krissia, Carrie and I














Problem#1:
In this problem that Mr.Harbeck gave us, we had to find the base of the triangle. This picture explains how I solved 'C' using the Pythagorean Theorem.



Problem #2

The first you need to do is, you need to find out each side of the square. Then that will give you sides 'A' and 'B' for all the triangles, since they're all the same length. Since you know sides 'A' and 'B', you need to find the length for the hypotenuse, which is 'c'. Once you have the length of 'C', add up all the sides together which will give you the perimeter.



Pay It Forward

Saturday, January 3, 2009
For my act of kindness, I'm thinking of helping anonymous people like the elderly, children, and the homeless. Some of my ideas to pay it forward was to help at an old folks home, help at the Children's Hospital, babysit for free, volunteer at a Christmas cheerboard, shovel someone's driveway, do community service, do chores at home without being told, and to donate money, clothes, or toys. I thought about going to the Children's Hospital or Calvary Place. I'm going to pay it forward during the break.








What I ended up doing was I made cards with Abby, Alyanna, Carrie, Gelli, Sutchai, and Tracy. The cards we made were about paying it forward, explaining what pay it forward is, why we are doing it, and how others can help. We all participated and equally shared the work by thinking, writing, drawing, and coloring.

On the front of each card said, "Pay it Forward" and to read before thinking to even throw it out or something similar. If you think about it, do you think you'd read something handmade made by anonymous people in the mail? Would you throw it out without even reading it? I honestly probably wouldn't take the time to read it, but maybe if it said something like, "Please read before throwing out." or "Before you even think of throwing this out, please read it." I'd probably read it. We also drew pictures on the front of the cards like flowers, cartoons, and forward symbols like the ones on a VCR. In the inside of the cards basically covered the who, what, when, where, why, and how. We also drew diagrams of one person paying it forward to three other people, each of the three paying it forward to three other people, and so on. We showed how it can spread quickly to many people and around the world. We also attached a lollipop to each of the cards to show our appreciation to pay it forward. We put the cards into mailboxes of unknown people.

I felt that I have done a good deed by spreading the message to others. I also felt like watching someone open their door and read what we had left in their mailbox and how they would react. I think the people whom I have given it to would have probably had a happy feeling reading the card and had a smile on their face wondering who had made the cards. I'm hoping that the people who received the cards actually read it and don't tend on throwing it out. I hope that they also pay it forward to help us spread the message.

Do I think that one person can make a difference? I know someone can make difference, it may not be a huge difference like to stop global warming but everyone counts. Even if that difference is very little, it will continue to grow no matter how small it may be. It is almost like a tree, it'll start out small and it will take time for it to grow, but in the end it is a large beautiful tree, and all the waiting really paid off. I think if you really believe in yourself that you can make a difference in our world and that you never give up, you will make a difference. No matter who you are. Age? Size? Culture? Ethnicity? That all doesn't matter, what matters is what is in you! Every little difference can make a HUGE DIFFERENCE! EVERY PERSON COUNTS!

Chapter Two: Combining Like Terms and the Distributive Property

Script:
Detective Brooks: Hello there, I'm Detective Brooks.
Lorie: Hello, I'm Lorie.
Detective Brooks: I see you're doing some kind of paper work.
Lorie: Yes, it's my homework! Have you heard of it?
Detective Brooks: Of course I have. What kind of homework is it?
Lorie: Combining like terms and distributive property.
Detective Brooks: Oh, I see. I was really good at that when I was in school.
Lorie: Really. *sarcastically*
Detective Brooks: I was, I probably still am. I can solve anything, well almost anything. What's the question?
Lorie: Sure you are. The question is n+3-5n+12.
Detective Brooks: Why don't you try and solve it, then I'll check if you're right.
Lorie: Alright then.
Lorie: My answer is -6+15.
Detective Brooks: Well it looks to me that you're wrong!
Lorie: That's impossible!
Detective Brooks: It's possible.
Lorie: If you're so good at this, why don't you tell me where I went wrong?
Detective Brooks: I will.
Detective Brooks: First combine like terms and remember to look at the operation sign. n-5n=-4 and 3+12=15. Therefore, the answer is -4+15. Do you see where you went wrong?
Lorie: Yes, now I see my mistake. I combined 5n and n, I've forgotten 5n was negative.
Detective Brooks: Now you understand, try and solve this question. 2 + 4(3n+8), what do you think the answer is?
Lorie: I think it might be 12n+10.
Detective Brooks: I'm sorry, but your answer is incorrect. First multiply the number closest to the bracket, which is 4. Multiply it to the first number in between the brackets, 3n. 4x3n=12n. Now multiply 4 to the second number, 8. 4x8=32. The question should now be 2+12n+32, all I have to do is combine like terms. 2+32=34, the question simplified is 12n+34!
Lorie: Oh, I'll try to remember that! I'm beginning to understand algebra.
Detective Brooks: That's good, do you know where you made your mistake?
Lorie: Yes, I didn't multiply 4 and 8 together. I just multiplied 4 to 3n and got 12n. After, I added 2 and 8, then I came up with 12n+10.
Detective Brooks: Don't worry, you'll get better and solve it like a mystery!
Lorie: Thank you for your help Detective Brooks, I really needed it! You're a really great detective!
Detective Brooks: Thank you Lorie, you're not so bad yourself!




Chapter Three: One Step Equation Solving

Additive:
The additive equation that I am going to explain how to solve is n+3=5. The first step is to isolate the variable. Then you add the opposite and cancel them out because they are zero pairs. Second, you balance it out by doing the same thing to the other side. So, your left with n=2. So after solving the equation, you have to verify! The first thing you do is rewrite the equation. Second, you replace the variable with the answer you got. The last step is to write down 5=5 to show that you are done.





Subtractive:
The subtractive equation that I am going to explain how to solve is 5-n=3. The first step is to isolate the variable. Second, you add the opposite, which is -5 to +5. Then you cancel them out because they are zero pairs. Third, you balance it out by doing the same thing to the other. So, you subtract 3 from negative 5 and now you are left with n= -2. Then you have to verify! You first need to rewrite the equation. Second, you replace the variable with the answer you got. Last but not least you write down 3=3 to finish it off!






Multiplicative:
The equation that I would explain how to solve is 5n=10. The first step is to isolate the variable. Then you add the opposite by dividing 5 by 5. Second, you need to balance it out by doing the same thing to the other side. So, you are left with the answer n=2 Next you need to verify! You first need to rewrite the equation. Second, you replace the variable with the answer you got which is 5 (2) = 10. Last but not least you write down 10=10 to finish it off!





Divisive:
The equation that I would explain how to solve is n/2=4. The first step is to isolate the variable. Then you add the opposite by dividing 2 by 2. Second, you balance it out by doing the same thing to the other side. Third, you need to verify! You first need to rewrite the equation. Second, you replace the variable with the answer you got. Last but not least you write down 4=4 to finish it off.


Chapter Four: Algetile Video

This is a video Carrie and I made on how to solve an additive equation, a subtractive equation, a multiplicative equation, and a divisive equation.


Arielle's Integer Story

Friday, October 24, 2008
This is "THE UNTOLD JOURNEY OF SPONGEBOB SQUAREPANTS: SAVING GARY". It all began under the sea, in the city of Bikini Bottom, south of Conch Street, in a pineapple...the home of Spongebob Squarepants. Every morning, Spongebob would hear the horn and turn it off, took a shower, got dressed, made his and Gary's breakfast, would eat together, and went off to work. This day was different from all the others, when Spongebob made his and Gary's breakfast, Gary never came.
So Spongebob called Gary, "GARY! I MADE YOUR FAVOURITE, SEAWEED KRUMBLE WITH COVERED WITH SEAWEED FLIES!"
Gary still never came, Spongebob began to worry. He looked all around and over his pineapple home, still no sign of Gary.

As he got out of his house, h
e saw a big package right in front of his door with big bold letters that said, TOP SECRET. Spongebob had almost forgotten that Gary was missing and was very curious to see what was inside. He ripped open the flaps of the package and out popped a tape player. Spongebob pressed the play button to hear what was on the tape. It was Plankton!
Plankton said, "If you ever want to see that slimy, shell covered pet of yours, solve these questions or give me the Krabby Patty recipe! MUAHAHA ! Wait a second, I forgot to play the evil music. *Plankton plays evil music* MUAHAHA ! I HOPE YOU KNOW YOUR....MATH! HAHAHA!*tape ends*"
Spongebob really wanted to see Gary, but he didn't want to give Plankton the recipe, so he decided to solve the questions. Spongebob found a piece of paper that had one of the questions on it.
The piece of paper said, "(+16) + (-9) = ? Choose the clam with the right answer."

There were 3 clams, the first one said -7, the second one said +25, and the third one said +7. The question looked very familiar to him, he took a moment to think, and it finally came to him. Spongebob used a number line to get the answer. He got +7, so he chose the third shell, and he was right!
The clam opened up and said, "Go to the Chum Bucket and there you'll find the next question."


Spongebob did what the clam told him, he ran as fast he could to the Chum Bucket! He finally got there, he was panting like a dog as got inside.

After he caught his breath, he looked around to find that no one else was to be found. "Hello! Anybody in here?"

He said in a loud voice, and then he heard a voice, but it he's never heard it before. "Spongebob, is that you?"

"Yes, who are you and how do you know my name?"

"I'm Plankton's computer and Plankton told me a lot about you. Would you like to know the next question?"
"Of course I do, but where are you?" Spongebob asked looking around.

"I'm in the back room near the counter."
Spongebob went to the back room and was amazed to see such the large computer that spoke. "So what's the next question?"
The computer showed the question on its monitor, the question was (+11)+(-3)=? Spongebob looked at the question and thought about another way to solve the question, then it came back to him, integer chips! He took out the zero pairs and was left with +8. He typed in the answer and he was right. The computer said, "CORRECT! The next question is at the beach beside a sand castle."



Spongebob was too tired to run or walk, so he whistled for the seahorse. The seahorse brought him to the beach within the blink of an eye. Spongebob was having a hard time finding the sand castle since many fish were there and it was a hot sunny day. Spongebob finally spotted the sand castle, but there were young fish playing with it. So he thought of something to get rid of them.
"I got it! FREE ICE CREAM AT SQUIDWARD'S HOUSE!"
Those fish ran in a hurry, pushing and shoving to leave the beach! He finally went to the sand castle and found a shellfish waiting for him.

"Why, hello there shellfish of Bikini Bottom!"
The shellfish didn't respond, but the shellfish wrote the question on the sand. The question was (+3)+(+2)=? Spongebob knew the answer right away, he wrote +5, and he was got the answer right!



After the shellfish led him to the juice bar. There he found another question on the counter and the shellfish had disappeared. The question was, (+10)+(-5)=? and it said to buy a drink. Spongebob remembered that he had $10 in his pocket, so reached into his pocket, and pulled $10 out. He also remembered another method for integer questions, using have and owe. Spongebob looked at the question and said to himself.
"Have 10 and owe 5=have 5!"

Then a large fish dressed in black had shot out from behind the counter and said, "You're close, very close to getting Gary back, but you must do as I say, and I am not Plankton nor do I work for him!"

TO BE CONTINUED...




CONTINUATION OF "THE UNTOLD JOURNEY OF SPONGEBOB SQUAREPANTS: SAVING GARY" ...


"Please don't hurt me, I'll do anything, and I mean anything! I don't want to die! I WANT TO LIVE!" Spongebob cried.
"Alright, come down yellow one and give me your money! "
"Here take it, take it all! Who are you?" Spongebob asked in a shaky voice.
"I'm going to ask the questions around here and I cannot reveal my identity! Call me, boss for now." The large fish said in a big voice.
"Okay, whatever you say...'boss'."
"The first thing I want you to do for me is to answer this integer question. The question is, (-6) - (-6) = ? I want you to answer the question with these square objects."
"Umm, integer tiles...'boss'?"


"Yes, whatever...Answer the question!"
Spongebob thought about the question and found a solution. First, he rewrote the question as an addition question. After he arranged the positive and negative integer tiles, so that they were aligned with each other. There were zero pairs, so he removed them, and was left with zero.
"The answer is zero!"
"HAHA! That is wr.....right! You're smarter than I thought. The next question will be more challenging!" He laughed.
"Where is Gary?"
"I cannot answer that question. It is for you to find out."
Spongebob was very confused. He had to follow 'boss' around everywhere, as he was ordered to do. They went to the Krusty Krab.
"I work here, but I don't have work today. Mr. Krabs said I had a day off. Excuse me boss, but why are we here?"
"Uhh, no reason. Just here for some Mon...Mondays!"
"It's Wednesday boss."
"Of course it is, I knew that. Stop questioning me!"
"Sorry boss."
"He sounds strangely familiar, but who does he sound like?" Spongebob said to himself.
He thought about it as he went into the Krusty Krab.
"You stay right next that broken table in the far corner."
"Yes sir! I mean boss!"
"Alright lad....I mean Spongebob!"
"That's strange, that's exactly what Mr. Krabs calls me. What are the odds of that? Haha!" Spongebob laughed.
'Boss' went into Mr. Krabs' office and locked the door shut behind him. Spongebob waited for about 5 minutes or so and 'boss' came out of the office.
"What were you doing in there?"
"Nothing, nothing you need to know boy!"
"You really remind me of Mr. Krabs, but you two are nothing alike!"
"Me? Mr. Krabs? Get out of town!"
"Hmm, there's just something about you that .."
"Alright, alright! It's me, Mr. Krabs!" Mr. Krabs says as he takes off the costume.
*Spongebob gasps* "Mr. Krabs! Why would you such a thing?"
"I don't know, I wanted to help you get Gary back. I'm sorry lad!"
"It's okay! Now let's go find Gary!"

Spongebob and Mr. Krabs began a search for Plankton, since he was behind all of this. They asked many fish, eels, starfish, and other underwater creatures, not one had seen him. Spongebob and Mr. Krabs thought about the one place where Plankton would be.
"The Chum Bucket!" They both yelled.
As they got into the Chum Bucket, it was empty. There weren't any tables or chairs or anything, just doors.
"Spongebob and Mr. Krabs, we meet again! MUAHAHA!"
"Where are you and why did you take Gary?"
"I cannot tell you where I am and I took Gary because I knew you cared about him. Maybe, if you give the ... KRABBY PATTY RECIPE, I'll give him back."
"Never! Not in a million years!" Mr. Krabbs shouted.
"Come on Mr. Krabs, look at poor Gary! Just give him the recipe!" Spongebob pleaded.
"See this laser? It can blow up the Krusty Krab, with just one click!" Plankton said as he showed Spongebob and Mr. Krabs the laser.
"Alright, I'll give you the recipe! Just don't blow up the Krusty Krab! There is just one question you have to answer before you get the recipe from Krusty Krab and show us Gary."
"Okay, here he is! What is the question?" Plankton asked while setting down Gary on the floor.
"(+2) + (+5) - (-4) = ?"
Plankton grabbed a sheet of paper and a pencil. He began writing the question down and thought really hard. He finally came with a solution!
"Is it +3?" asked Plankton.
"You're ... actually right!" Mr. Krabs said.
"So what does this question have to do with the Krabby Patty recipe?"
"Uhh, nothing. Spongebob grab Gary and run!" Mr. Krabs yelled.
