science about something

this is about something that is ???

what is a crystal: definition of a Crystal is a piece of a homogeneous solid substance having a natural geometrically regular form with symmetrically arranged plane faces.

How can you make sugar crystals: how to make them

how is this a seperating mixture: it is when the sugar attaches to the string when the water dissolves

dilution series

We did a experiment about dilution series
Aim: to see what happens when you try to dilute

Equipment: a potassium permanganate crystal, six test tubes, tweezers, a plastic transfer pipette, a test tube rack , a 10 ml measuring cylinder

Method:
1. Place the six test tubes in to the test tube rack and number them from 1 to six
2. use the measuring cylinder to place 10 ml of water in test tube one and 5 ml of water in the other five test tubes
3. then using the tweezers put your one small potassium permanganate in test tube 1 and
4 shake it until the crystal is dissolved 
4.5. rinse the pipette
5. then using the plastic transfer pipette transfer 5ml from test tube 1 in to test tube 2
6. then repeat then process 4.5 to 5  but use the 5ml from the test tube you just put it in and put it in the next one over

Result: test tube 1 was dark purple and as we transfered the 5ml from tube to tube the colour got more faint until test tube 6 it was quiet faint


dilution : the action of making a liquid weaker by mixing in something else, or a liquid that has been made weaker in this way:

Concentration is when a thing is in one spot

the giver

the giver
i think the moral of the movie that it is meant to be a perfect world  no war no mistakes no murder but instead it was not a perfect world the just made murder at home just could it under a different name it was could to live in else wear but they don't know that it is wrong because they get injections that is said to be for your heath when actually it is to remove your emotions and the world / community's are all controlled people called the elders and the elders are controlled by the main elder

i like the movie because i could understand the moral or the point they were trying to make

i liked the ending because they got all there memorys back i dont think it there was anythink wrong with the end i would keep it the same














cheif elder she is the main and only villain in the movie she thinks that she has made a perfect world and controls every one



 the giver he was the old telephone receiver

 Jonas / the receiver he is the new telephone receiver of memorys

Reviews

good

 I wasn't sure on this film to begin with due to it being in black and white but I love that the reason for this was so when the memories returned to the main character you could see the colour and how things are different from when the city felt nothing. This was such a great way of showing why the planet needs emotion and not to be cut off from all emotions. 

I like this review because this is what i thought at first

Bad

Jonas live in a seemingly idyllic world of conformity and contentment. When hestartsspending time with the giver Jonas discovers the dangerous truths of his community's secret past Armed with the power of knowledge, Jonas realizes that he must escape from their world to protect himself and those he loves a challenge no one has ever completed successfully 10/10 wouldn't watch again

i disagree with this review because i liked the movie

Filtration in science

We done a expirement trying to fillter real dirty water in to cleanish water
Method: we filled a large becker with dirty water we got a funnel and a conical flask we half filled the funnel with pebbles to fillter out the larger solids from the water then we took the pebbles from the funnel  and used the water from the conical flask and repeated the prosess again but with charcoal then we tipped out the charcoal and used the water from the conical flask again but this time we used fillter paper and a clean conical flask then the water was cleaner than what it started as but i still would not drink it cause it was still light brown it would of turned out better if we did more steps it would of be cleaner

here are two fillters for real world situations

Dino excavation

Today we excavated or toy dinosaws from the plaster we made and put the dinos in i had a different ratio than the rest of the class mine was ⅔ plaster of paris and ⅓ water every one else was ⅓ plaster of paris and ⅔ water mine was alot harder to get out i was the last person done

EOTC Week

EOTC

Last week and yesterday we had education outside the classroom on tuesday we went to a marare and the museum on wednesday we went to omaka scout camp with youth town we done team activities and played games and went for a swim on thursday we went to adrenaline forest and had a play at spencer park i completed 1 2 and 3b then yesterday on tuesday we went back to omaka scout camp with youth town we did slacklining oreintubeing that is floating down a river in a large tire tube and had to find letters and we did fire building and archery all the activities were fun

my electro magnet

i made my own electro  magnet i found out it had to have about ten volts then i made some changes that the teacher suggested and it works with 3 volts and 1.5 volts that is a double a battery

here of some photos of it before and after

this was my test to see if hire voltages made the strength more powerful

0.5volt 110 paper clips

1 volt 7 paper clips or 27 paper clips

1 volt 110 paper clips

turns out it was not more powerful the hire the voltage

1 volt was the same strength as 10 volts
