Students Blog Too !!

Our grade 4 students have been working on developing digital portfolios as evidence of their thinking and new understandings in math and science since the beginning of the year. Because these snippets of their learning are personal and still developing as accurate reflections of their learning, they are not all made public. Recently, however, students have been actively expressing interest in sharing the work that they do at CSS. We have asked that when they complete a blog post, that they send us an email if they would like to share it. Some of these powerful posts have been included below. Please share your feedback by completing this form...

0D is just a single dot it has no dimensions, no height width or depth just one dot. In a dot there is not one unit of height or width or depth that is why a dot is so small. 

1D is a line because there is only 1 dimension-Width (<----->)

                                     

2D: Everyone has probably seen a 2D movie, well a square is also , there is 2 dimensions in a square, height (^ v ) and width (<----->)


3D: There are 3 dimensions in a cube that's why they call it a 3D shape. The 3 dimensions are: Height (up and down), width (<----->), and depth. 


When we measure height, we measure the square's and/or cube's units that go up and down. Height is the tallness of a shape, height goes ^UP^ and vDOWNv. 


Depth is how deep the shape is, how far can you reach into it, if you can turn the shape sideways you can see how deep it is


Width is the fatness of the shape, width goes this way: <----- and this way: ----->.


To find the volume of a shape you have to multiply the shape’s height, width and depth.


To find the area of a shape you need to multiply the shape’s height and width

0D is just a point.

1D is only a line for with just height for example measuring how long a pool is.

2D is something with just height, and with, for example measuring the area of a pool.



3D is some thing you can reach into and has with, depth, and height, for example measuring the volume of a pool.        

Width is across something like a 6 by 12 peas of paper the 6 could be the with because it can be across the paper but so can the 12.

Depth is how fare you can reach into something like even if you draw a 3D shape on a peace of paper you can't reach into it.



Height is how tall some thing is like a  3x3 cube the height would be 3 because it is a cube and all the sids are the same so it has to be 3.

Area is how big a square is for example a 3x3 square is the area is 9 because the height is 3 and the width is 3 so you multiply them together to get the area which is 9.

Volume is how much stuff you can fit in a cube. You get this by multiplying the length by the hight and the width

Jonah N. - Decomposing Fruit: One Month Later...

Our fruit has been buried for one month and has rotted. We are seeing if our little specimen can grow a plant of some sort. I noticed that the height of the soil in the container dropped by 2 centimetres and has mould around it. I wonder if the nutrients inside the lemon can grow more than one plant or type of plant. What if the juice in the lemon mixed with a different chemical and doubled the size of everything it touched? I noticed when you leave something out in the open everyday it will get smaller, harder, lose weight, and crinkle more and more. I wonder if our fruit was exposed to a different gas such as helium could it still grow a plant? What if there was no air, would it still be able to grow a plant or would it die?

I noticed that the kiwi has split into pieces and if you look carefully you will find some of the rotten fruit. I noticed a tiny scent of fresh kiwi is there to smell. 
I wonder if my fruit's seeds will make more fruit and if not why? 
I wonder if there will be over 4 kiwis that will grow in the portable container?
I wonder if the kiwi will grow into half kiwi's like the one we buried where you could see the core or a full kiwi where you can only see skin? 
I wonder if the new kiwi will rot faster or slower? 
I wonder if the kiwi will be a different color of brown skin, black seeds, and green core.   
What if when the new fruits grow will there be halves of kiwi or whole kiwis?
What if the kiwi does not grow at all?

One Month Later

Hi! Welcome back to the Science Lab. Looking at the title it says it is a month later since we buried our orange in soil. Today, (Jan 30 2012!) we took out our specimen in dirt and did the following; we mixed it with a popsicle stick, then poured some water into the soil and mixed it again. We added new soil on top of that and mixed it. We had too much water but the extra dirt drowned it. Now a few Q and A's...

Q: I noticed...
A: I noticed that the smell had changed. When we opened the container it was crusty and dry until we mixed it with water.
Q: I wonder...
A: I wonder how long it took/takes our fruit to decompose into the soil. How long will it take the plant to grow in the soil?
Q: What if...
A: the plant takes more than a month to grow? What if we left the fruit out in the open for longer?

This blog post is about what happened to our watermelon after we buried it and left it in an container for 1 month. The questions I now have are what if the next watermelon that grows looks completely different because it was from a rotting fruit and instead has pink skin and a green middle? 

I noticed that my group's watermelon was almost completely gone except for the sticker and 1 piece of skin. I think that the sticker didn't go away because it is not natural material like the watermelon. 1 thing I don't understand is why that 1 piece of skin hasn't decomposed yet? I guess that question may never be answered, but I still wonder.  

I wonder if we injected an oranges D.N.A into the watermelon seed if it would make a brand new type of fruit? 
How long would it take for a plant to grow and if we left it outside would it take a longer amount of time?
