Serena's Surface Area and Volume Post

Here is a link on surface area:

Here is a video on how to find the surface area of a rectangular prism:

Triangular Prism: base x height divided by 2 x height.
3x8.5/2 x 5
=12.75 x 5
=63.75m³

Rectangular Prism: lxwxh
=20x8x16
=2560cm³

Triangular Prism: base x height divided by 2 x height
=8 x 4/2 x .5
16 x 6.5= 104
3/8= 0.375
0.374 x 104 =39cm³

Circular Prism: pie r squared x height
d/2= radius
12/2= 6
=3.14 x 6 x 6 x 15
=1695.6cm³

Here is a link on square roots:

1. Explain the pythagorean relationship.

-The relationship between the lengths of the sides of a right triangle

-The sum of the areas of the squares attached to the legs of a right triangle equals the area of the square attached to the hypotensue

2. Find the missing side length

3. Is this a right triangle?

Serena's Pay it Forward

Part 1: What is Pay it Forward?

Pay it Forward is an act of kindness towards others. Without asking for anything in return you ask them to pay it forward and help 3 other people.

Part 2:

What was your Pay It Forward act of kindness?

My act of kindness was buying little toys like puzzles, stickers, bouncy balls, paper cranes, paper elephants, paper lion and giraffes, pencils, notebooks, and erasers. After we put the toys in the goodie bags to give to the children in the Children's Hospital. In the end we made 50 bags, 25 for girls and 25 for guys.

Why did you choose this activity?

I choose this activity because I knew that there are sick children in the hospitals and so I wanted to help them and make their lives a little bit happier.

Who did you help?

I helped the children in the Children's Hospital.

What did you do?

We went to the Children's Hospital to give goodie bag to them.

When did you do you act of kindness?

I did my act of kindness on Monday, November 14, 8:00am.

Here is a link for more information on what we did.

Part 3

How did your act of kindness go?

My act of kindness went really well because we were prepared and we had everything planned out.

What Happened?

The first thing we did was plan out what we were going to do and how we were going to do it. Then, we contacted the hospital by emailing them and we asked if we could come by and drop off goodie bags for the children. After, we went shopping at Michael's and Dollarama to buy the supplies we needed. The next thing we did was sort everything out and put them into the bags. We also made paper cranes, paper elephants, paper lions, and paper giraffes to put in the bags. After, we made cards that had inspirational quotes and tied them on the handle's of the bags. The next day we went to the Children's Hospital and we dropped off the goodie bags. We also received a certificate from the hospital saying thank you Sargent Park School.

How did you feel?

After doing my act of kindness I felt that I had made a difference in those 50 children's lives, by doing something as little as giving a goodie bag.

How did the person or people react?

The person we gave the bags to was very thankful and surprised at how many bags we brought. She said that "a lot of children are going to be very happy because of you guys".

Did you ask the person or people to "Pay It Forward"?

Yes, we did ask the person to pay it forward.

How did they react to your request?

She were surprised and interested in what we where doing. She also said that she will try her best to pay to forward.

Part 4

Why is the idea of "Pay it Forward" important?

The idea of pay it forward is important because it gets people to think about other people instead of thinking about themselves. When you pay it forward, the people who you helped will help 3 other people and those people will each help 3 other people. If everyone pays it forward then everyone's lives is going to be a bit happier.

Has your act of kindness made a difference?

Yes, my act of kindness had made a difference to the children we gave those bags to. Even though we didn't do anything big we still know that at least we made some children happy.

The lady Tania from the Children's Hospital sent us a messaged to us the next day. This is what she said

"Thank you again for the fantastic gift bags, your group really put a lot of work into it and they were beautiful. The kids loved them! There was one girl who’s mom was there and commented that they should do something nice like that too"

Serena's Graphing Post

1. Use your notes to list the different types of graphs. Please list the advantages and disadvantages of each graph

2. How can graphs be misleading? show 3 ways.

3a) The following chart shows Pizza Sub Sales over a month. What 2 graphs would show the information accurately?

A line graph and a bar graph would show the data accurately.

3b) If you were selling Pizza Subs would you continue? How does your graph explain your answer.

If I was selling pizza subs I would continue to sell because my graph show me the every week I have been selling more pizza than the last week. so, there is a good change that I might sell even more the next week.

4. Below you see 2 different examples of graphs showing healthy choices sold at the canteen. If you had to convince Mrs Mota that we should continue selling healthy choices which graph would you choose?

Answer: If I had to convince Mrs. Mota that we should continue selling healthy choices I would choose the line graph because it show that more people are buying more healthy food choices every month.

4a) Change each graph so that your information looks even MORE impressive. You may not change the data just the graphs.
