distillation

In science on tuesday we did a expirement on distillation
Aim: to remove water from coke using distillation
Equipment: bunsen burner, trypod, heat mat, gause mat, retort stand with clamp, delivery tube and bung, beaker, conical flask, boiliing tube, coke and ice with water
Method:
1. pour about 100 mL of your coke in to your conical flask
2. put the bung and delivery tube in the top of the conical flask
3. then put your boiling tube in the clamp
4 put the bottom of the boiling tube in the beaker with the ice with water and then put the other end of the deliver tube in the top of the boiling tube
5. light the bunsen burner then put it under the tripod that has the conical flask
6. once the water has evaporated turn off the gas
Results: once my coke started to boil it only boiled on one side and made a wavy pattern once i there was a medium amount of water in the boiling tube i turned of the gas it took about 5 minutes i could move it to the sink and slowly run water on the conical flask to cool it down further.

how does distillation separate two liquid? it evaporates the liquid with the lower boiling point

what are the two chemical process in distillation: first is evaporation and the second is condensation

how is distillation used in real life? to make drinkable water, to make diesel, petroleum and alcohol etc

Introduction

In DTE so far this term I have had to do more writing than in English, play inter land, Make a attempt of a google site using google sites on google on chrome on a chrome book that is connected to the wifi that is wirelessly connected. 

DLO (Digital Learning Object)

Reflection

i said i made a attempt of a site. This is an understatement. My site was pretty uch the only work I have done, except for play interland one period. I liked interlaand, but i am looking forward to next week because we are playing with robots

.

question

what robots would you like to play with. (do not reply to this question in the comments).

Question

sugar crystals in science

we made started to make sugar crystals in science

Aim:to make sugar crystals
Equipment: Beaker (x2), Bunsen burner, heat mat, try pod, gause mat, styrofoam cups for each person in your group, Popsicle sticks, measurig cylinder, stirying rod, sugar, water , food colouring (optional) and time to let it sit.
Method: get your 50 ml of water to boiling then turn of the heat and slowly add sugar small bit by small bit and mix it until the sugar dissolves and then when after about 2 minute of the sugar will not dissolve any more then add a couple drops of food colouring if you want then pour in to as many cups as in your group then put your Popsicle stick in your cups after wetting the Popsicle stick and covered it in sugar and let it sit for a couple days
Results: on the fifth day we ate it. it tasted like sugar some time in between someone broke all the candy

day one soild on top

other facts

what is a saturated solution : is when something is so concentrated that it can not dissolve or absorb any more solute in to it for example say it was raining and you had to walk to school and  your clothes get so wet that it can not get any any more wet.

why do you do you use a saturated solution to grow crystals: because it means that the solute separates from the liquid and forms on around the smaller crystal to make a bigger crystal?

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
