Water Systems

Today we started our new unit "Water Systems"
 The three main Topics we are going over are, Intruduction to water, Water drainage and Water treatment. We made a K:W:H:A:L:Q chart to learn about water.
Some of our K's include,
K: Water is liquid, Nt solid, different types of water,Salt,Fresh and Tap, To make water clen you have to boil it.
Some of our Wants to lern abut water are,
W: Why is ocean water salty, how is fresh water fresh? What happens to water in space?
We actually watched a video from Chis Hadfield in space! He explained to us what happens when you wring out a towel soaked in water. When he rung out the towel, the water created a "Tube" like forcefield around the towel and is hands. Then when he let go the water stuck to his hand, so that he could wash his hands.
We went over the parts of the Water Cycle one by one.
Accumulation: The process in which water pools in large bodies. Ex) Oceans,Ponds,Seas,Lakes
Condensation: The process in which water vapour in the air turns into liquid water, Condensing water forms clouds in the sky.
Evaporation: The process in which liquid water becomes water vapour. Ex) Water Vapourizing from puddles, lakes
Precipitation: The process in which water falls from th sky. Ex) Rain, Snow, Hail
Surface Runoff: Any rain, snow, melt or other water that flows in surface streams,rivers or canals
Transpiration: The process in which some water within plants evaporates into the atmosphere. This is why it can feel muggy in a rain forest.

 need to lable the eye
-define each
-how does each light bend
-how wil you look

MATHLETE Friday :)

MATH problems:
A number of children are standing in a circle. They are evenly spaced and the 7th child is directly opposite the 18th child. How many children are there altogether?
22; in half of the circle there are 11 children because 18-7=11. Multiply 11x2=22!
We are brave sailors always riding the sea
We are less than one hundred but as tough as can be
We sleep in three bunkers on top of each other
Our numbers double from one bunker to another
We dance in joy all through the night
In groups of fives under the moonlight
Last night twelve of us were swallowed by waves
Leaving alive more than two third of the braves
Still we continue the journey refusing to fail
So tell me how many of us are left to sail?

58 sailors are left.

1. From line 2: Total number of sailors is <100.
2. From lines 3 & 4: Let number of sailors sleeping in bunker 1 be X, then number of sailors sleeping in bunker 2 is 2X and in bunker 3 is 4X,
i.e. Total number of sailors = X+2X+4X = 7X and thus it is a multiple of 7.
3. From line 6: dancing in groups of fives means the total number is a product of 5.
4. From lines 7 & 8: 12 of the sailors drowned in the sea, leaving more than two third of the sailors alive, so the total number is > 36 (3 * 12).

Summing up all the above given information, the total number of sailors is <100 and >36, it divides by 7 and 5, which adds up to the total number of 70 sailors.

Since 12 of the 70 sailors died in the sea, there are 58 sailors left to continue the journey.

A merchant can place 8 large boxes or 10 small boxes into a carton for shipping. In one shipment, he sent a total of 96 boxes. If there are more large boxes than small boxes, how many cartons did he ship?
11A merchant can place 8 large boxes or 10 small boxes into a carton for shipping. In one shipment, he sent a total of 96 boxes. If there are more large boxes than small boxes, how many cartons did he ship?
11 cartons total 
7 large boxes (7 * 8 = 56 boxes)
4 small boxes (4 10 = 40 boxes
11 total cartons and 96 boxes
  • Cakes are round but Pi are square.
  • Why did the math book look so sad? Because it had so many problems.
  • How can you make time fly? Throw a clock out the window!
  • Why do plants hate math? Because it gives them square roots.
  • What do mathematicians eat on Halloween? Pumpkin Pi.
  • Why did the ath book kill himself? Because nobody understood him

Questions... just behind the mirror


1. Name the type(s) of mirror that forms...
     (A)A real image?
            Concave mirrors. Only a concave mirror can create a real image, due to the light rays converging, meaning they actually recombine back together.

     (B)A virtual image?
          Convex mirrors. The image is always seen behind the mirror.

     (C)A virtual image that is larger than the object?
           Concave mirrors can make the image larger.

     (D)A virtual image that is the same size as the object?
           Convex mirrors make you look the same size.
             (Virtual image- An image located where reflected rays only seem to originate) 

2. Imagine you have sprayed a bowl with shiny, reflective paint.
     (A)Which part of the bowl serves as a convex mirror?
           The part of the bowl that doesn't hold the food.

     (B)Which part of the bowl serves as a concave mirror?
           The part of the bowl that holds the food.

     (C)How do you hold the bowl to see an inverted image of you?
           You hold the bowl

     (D)How do you hold the bowl to see a larger, upright image of you?
          You hold the bowl so the base is facing you

     (E)How should you hold the bowl to see a smaller, upright image of your face?
          You should hold the bowl so you are facing the part which the food goes into.

3.In a funhouse, which kind of mirror would you use to...
     (A)Make yourself look taller
           Convex mirrors          
     (B) Make yourself look shorter
           Concave mirrors

LOOK!! I'm upside down!!!!!

 A CONVEX mirror is when the mirror is outward.
CONCAVE mirror is curved in.

Think of a spoon. Have you ever looked at yourself in a spoon? When you look at the curved out end, you see yourself streched out a bit. If you look at yourself in thr curved inward side you see your self upside down. Just a little example of a convex and concave mirror.

Is it a plane, is it a bird, no it's an eye

We did notes about the different parts of the eye. We started an eye diagram about different parts of the eye: Sclera, Cornea, Iris, Pupil, Lens, Retina

Video All Stars

Getting it together would help make it better
We liked the comedy/entertainment
We didn't like that we couldn't retry it

What we could have done better: Timing
What we did good: Have fun!

We liked the entertainment.
We disliked the time limit.

*We have one group whose video is not completed yet, but will be shown soon!
The man is explaining what it looks like when you mix colours, like red and green, and blue and green.

Blue, green, red, yellow,white ,purple.They are taking some colours away to make different colours. I like it they are funny.

Friday, May 02, 2014


Today in class we did two out of four centers, the centers were, make a movie about colour, and the other one was Benham’s Top. Make a movie was just a movie with background music and the four groups record their voice over one of Bill Nye’s videos. The videos will be put on one of the next blog posts. Benham’s Top was just cutting out a circle, half white half black. The white side had little round lines that looked like circles when it was spun. When the disc is spun arcs of pale colours are pattern induced, flickers are visible at the different places on the disc. Each person had seen a different colour, because no one has the same type of eyes. One person saw red and purple, another saw blue on the outside but brown in the middle, and someone else saw blue on the outside and red in the middle. If it does not work with the paper, go to Wikipedia under Benham’s Top.
