Dry Ice

A couple of days ago in science class we did an experiment using the involvement of dry ice. we started by getting into small groups, filled our beaker up with a bit of water, using some tongs  we got our piece of dry ice, took it back over to the beaker, dropped it in and watched the magic happen.The dry ice started to bubble and you could pour it on the table and play with the steam like substance. I didn't  known much about dry ice before that experiment but it is for sure something I would like to do again. Would you do this experiment if you had a chance to?This image below is not my image because I didn't get a photo, it is one off the internet.

Short Story

Footsteps slowly creaked on every step of the stairs, with a high pitch sound echoing through the hallway as if the teacher was running her fingers down a chalk board. I hug my blanket viciously as the bedroom door handle slowly turns. My heart skips a beat faster than a jump rope and a chills rush down my spine as a dark figure barges through the door. All I could see was a silhouette of the dark shady figure, with eyes greener than a forest and a hook for a hand sharper than a knife. The shady man comes closer and through the gap between the window the moonlight shins relieving he is wearing a ski mask darker than the midnight sky. This was the man that murdered the school music teacher and and midge at the school musical and the janitor this is the man that refers to him self as the black hood. This is the man that believes I am like him this is the man that made me bury my best friend alive and this is the man who is my father, this is the man that tried to kill me at prom and this is the man that used me to fake his own death he his a cereal killer he is a monster.

Titanic Seel Paragraph

S RMS titanic was a British passenger liner that sank in the north
Atlantic ocean in 1912

E After colliding with an iceberg during her maiden voyage from south
Hampshire to new York city.

E when the titanic sank it killed over 1,503 in total including
passengers and crew.

L There was new evidence found that the titanic had a twin sister
called the Olympic.

S It is believed that the titanic's twin sister was the ship that set voyage
instead of the titanic.

E Because the titanic was believed to have something gone wrong
during the test run their is new evidence showing that the olympic
and the titanic got switched  around a week before it set off for her
maiden voyage.

E According to Titanic researcher Ionians George, the two additional
potholes on Olympic were added about March 1912 during her short
stay in Belfast and before the maiden voyage of ‘the Titanic’.
So by April 1912 both ships had 16 portholes.

L Over the years people have spoken about the Titanic and learnt
how it sunk on that dreadful night in April 1912, however some
people are led to believe that it was in fact its sister ship the Olympic
that sunk as part of an insurance scam.

Home economics

Spiced Apple Muffins


In home economics we baked spiced apple muffins and I would have to say this is probably had the best turn out out of the rest. It had the best texture and had the most accurate measuring and they were really really tasty.

Ingredients:

Serves: 12

2 cups flour
3 1/2 teaspoons baking powder
1/2 teaspoon salt
1/2 cup granulated sugar
1 cup chopped peeled apple
1 egg, lightly beaten
1 cup milk
1/3 cup melted butter
2 tablespoons brown sugar
1/4 teaspoon cinnamon
1/4 teaspoon nutmeg

Directions:
1 Pre-heat oven to 180 degrees
2 Mix together flour, baking powder, salt and sugar.
3 Mix in apple, cover completely.
4 Add egg, milk, and butter.
5 Pour 3/4 full into greased muffin tins.
6 Mix topping together and sprinkle over unbaked muffins.
7 Bake for 15-20 minutes or until brown.
8 Eat them.

science

Aim to separate a solute from a solvent in a solution.

In science we did a distillation experiment and we separated the coke from the water is worked when we boiled the coke and it separated water from the coke and filled up in a different boiling tube.

 Equipment - A solution of saltwater , conical flask , heatproof mat , a delivery tube and bung , Bunsen burner , tripod , gauze mat , retort stand , boss head and clamp , boiling tube. \

Method -

 1. set up equipment as shown in the diagram   

2. add approximately 50 ml of saltwater into your conical flask  

 3. light your Bunsen burner open the air whole and genitally push the Bunsen burner  under the tripod  

4. heat the solution most of the solvent has been evaporated . Turn off the Bunsen burner 

How does distillation separate two liquids.

To separate a mixture of liquids, the liquid can be heated to force components, which have different boiling points, into the gas phase. The gas is then condensed back into liquid form and collected. Repeating the process on the collected liquid to improve the purity of the product is called double distillation.

What are the two processes happening during this reaction.

The process of reactive distillation involves using the reaction vessel as the still. In this process, the product is usually significantly lower-boiling than its reactants. As the product is formed from the reactants, it is vaporized and removed from the reaction mixture.

how does distilation used in real life.

But chemists also use simpler physical methods,distillation and filtration, to separate mixtures.Distillation can be used to purify water, make alcohols, or separate petroleum into various components that range from natural gas to gasoline to tar.

Science

Why do we use a saturated solution to grow crystals?
Crystals grow when the solution becomes supersaturated, meaning that there is too much sugar dissolved in the water. The extra sugar takes the form of crystals. To get a supersaturated solution you can either cool down the solution or let some of the water evaporate.

Yesterday we made sugar crystals.

Equipment:
Busen burner 
Glass rod
gause mat 
heat proof mat
tri pod
cup
popsicle stick
beakers 
measuring cylinder

Ingredients:
250 g sugar 
food colouring food flavouring
50 ml water

Method
Put your water on a boil then add your sugar little bit at time 
then mix constantly until it becomes a clear yellow then  pour it into a cup dip your popsicle stick in water then cover it in your leftover sugar and put it in to the cup wait 1-2 weeks until you crystals then eat and enjoy.

Drama

Today we had the ugly Shakespeare company come to our school and they preformed a play called taming of the shrew it was about domestic violence. I really liked this play the actors were funny and they made the play seem really cool. They added some music that made the play feel alive.  The bit that made me really enjoy the play was how they interacted with the audience. The conflict between the two sisters (Bianca and caterina) made every one laugh, they were always fighting and bickering on about how caterina should just get married to whoever so her younger sister Bianca can get married so she isn't forever lonely.
