Wood cut - Art

My work was inspired by the German Expressionism era. This was my first print, and I think it is okay. I want to cut a bit more out around the eyes on the forehead, also just above the lips.

Making Table salt - Science

Making Table Salt

Aim: To make sodium chloride crystals by neutralising an acid with a base (alkali)

Method:
1. Measure 10ml of hydrochloric acid (HCl) in the small measuring cylinder and pour into a 50ml beaker.

2. Add dilute sodium hydroxide (NaOH) to the acid a few drops at a time while stirring with a glass stirring rod.

3. Use the glass stirring rod to transfer a drop of the solution to a spotting tile. Add a drop of universal indicator. Is it neutral? (green)

4. Once it is neutralised (pH = 7 - green) pour the liquid into an evaporating dish and heat till it boils slowly.

Observations: Write one observation for each step of the method.

1. The acid was really strong so we had to use ten mills of base, and add 5 drops of acid.
2. The water evaporated really fast, but the water in the evaporating dish was still there.
3. After we were left with a white substance on the bottom of our evaporating dish.
4.

Word equation for the reaction:
Hydrochloric acid + Sodium Hydroxide --> Sodium Chloride + water 

Balanced symbol equation for the reaction:

HCl + NaOH = NaCl + H2O

Acids and Bases - Science

Practical Assessment – Chemistry – Acids and Bases

Aim:

To measure the pH of several solids and liquids using universal indicator solution and a pH pen

Equipment:

Spotting tile

Universal indicator solution

Samples of several solids and liquids

pH pen

Method:

1.       Take two samples of each solid/liquid to be tested and arrange on your spotting tile. (If you are testing a solid add a drop of water and mix it before adding indicator)

2.       Place one drop of universal indicator on ONE of each sample.

3.       Use the pH pen to measure the pH of the other sample of each substance

Results:

Substance	Colour with pH	Description	pH Meter reading	Description
Eg. Substance A	Pale Blue	Weak base	8.3	Weak base
Sugar	Blue/Green	Weak base	5.8	Weak acid
Lux flakes	Blue/Green	Weak base	9.9	Average base
Detergent	Green/Yellow	Weak acid	7.8	Neutral
Toothpaste	Yellow	Weak acid	7.4	Neutral
Fruit juice	Orange	Average acid	3.6	Strong acid
Window cleaner	Blue	Average base	7.1	Neutral
Citric acid	Red/Pink	Strong acid	8.8	Weak base
Cheesels	Blue	Strong base	12.6	strong base

Conclusion:

I think that the pH readings are very very incorrect because people in my class were mixing all the chemicals, so the readings were incorrect. 

Wood Cut Selfie - Art

For my selfie I've decided to blur out my eyes, and make the features more bold. I'm planning to make the edges all kind of blurred looking, because this picture is supposed to give the feeling of anxiety. This is why I'm using small, rushed looking lines.

Solo Performance - Music

1. The song I've chosen is I write sins not tragedies by Panic! at the disco.
2. This song tells the story about a groom who find out that his bride is cheating from over hearing a conversation between a bridesmaid and a waiter. 
3. I'm playing this on the ukulele because it's the only instrument I can play. 

Testing indicators

	Acid	Water	Base
Beet Root Extract	Pink/Crimson	Bright Pink	Dark Red
Red Cabbage Extract	Red/Pink	Blue	Green
Turmeric	Yellow	Yellow	Red/Orange
Cranberry Juice	Light Pink	Light Pink	Light Pink

Selfie Woodcut Reflection

In art we are doing German Expressionism inspired woodcuts of our own faces. The emotion that I been concentrating on while working on is Anxiety. One of my favourite pictures I've seen is this one done by Leonard Baskin. I like the way he uses positive and negative space, and makes the subject look elongated by using negative space. When I complete my final piece I want people to understand the emotion anxiety, and what it feels like. I now need to come up with a final design and translate it onto the wood.  

Science Experiment

Our first Year 10 Chemical Reactions

1. Magnesium reacting with oxygen:

Method: We held a strip of magnesium metal in the hottest part of a bunsen burner flame till it caught fire. We didn't look directly at the reaction because (safety reason)
Observations:
1. The magnesium metal was a grey, shiny, and flexible.
2. The magnesium burned with a very bright white light.
3. After it burned it was a white powder.

The word equation is:

The balanced chemical equation is:

2. Iron filings reacting with sulphur:

Method: We mixed equal amounts of iron filings and sulphur then used a magnet wrapped in paper to separate them. We mixed them again and added the mixture to a test tube and heated strongly.
Observations:
1. The iron filings were dark grey, powerish
2. The sulphur was neon yellow/green, powder
3, When we heated the tube it let off a smell of rotten eggs.
4. After the reaction a clump of black/grey stuff.


The word equation for the reaction is: Iron + Sulphur -> Iron Sulfide 
iron sulfate.The balanced chemical equation is: Fe + S -> FeS
