Science Testing pH

Aim: To test the pH of a range of household chemicals.

Equipment: A variety of household chemicals, spotting tile, red litmus paper, blue litmus paper,
Universal indicator solution, safety glasses.

1) Add a few drops of each chemical to a spot on your spotting tile. If a substance is solid or powdered you will need to mix it with a few drops of water before testing it.

2) Test the chemicals with litmus paper.

3) Test each chemical with a few drops of universal indicator.

Litmus Indicator

Litmus indicator solution turns red in acidic solutions and blue in alkaline solutions. Litmus also comes in a paper form. Blue litmus paper will turn red in an acidic solution and remain blue when added to an alkali solution. Litmus does not tell you how strong the solution is.

Universal Indicator
A universal indicator shows us how strongly acidic or alkaline a solution is.
The universal indicator has many different colours changes, from red for strong acids to dark purple for strong bases. In the middle, neutral PH 7 is indicated by green.

Method: 

For Cabbage and Beetroot: Chop the cabbage into small pieces until you have enough to fill 2 cups.

Place the cabbage in a large beaker and add water to cover the cabbage.

Boil over a bunsen burner for at least ten minutes for the colour to leach out of the cabbage.

Filter out the plant material to obtain a red red-purple-Bluish coloured liquid This liquid is at about PH 7. (The exact colour you get depends on the Ph of the water.) Place in a small beaker and leave to one side.

Repeat this method for the beetroot...

For the tea: Put 100ml of water into a beaker and boil turn off the bunsen burner and put three tea bags in the beaker.

Remove the tea bags when the tea is very strong

Place in a small beaker and leave to one side.

This is the one that I did 

For the Cranberry Juice: Pour into a beaker and leave one side.

For the turmeric: Mix 1 teaspoon turmeric in a 100ml cup of alcohol.

Place in a small beaker and leave to one side.

This is how my experiment worked out:

Social studies

In social studies, we are learning about creative writing so we had a week to write about a voyage to New Zealand.

This is my story:

 Arriving in Paradise   

Spencer FATTT Johnson was a gambler and made just enough money to live an ok lifestyle. He lived on his own without his parents.  

He had no kids and no wife. He was very poor because his parents

Sadly died from TB (TUBERCULOSIS)  and his parents worked as a servant for the rich.  From his parent's sad death he decided to move to New Zealand because he thought it was going to be cheaper to live there but boy was he wrong.

After a few days, he started gambling more just to get enough money to get a steerage ticket to New Zealand. When he was gambling he came across a very rich guy who also knew how to gamble, so Spencer went up to the rich person and challenged him to a 5 dollar game and the rich man said” 5 DOLLARS!! Lets up the money to 10,000 and he said 5,000 each. Spencer was shocked by how much money he wanted to put on the line. But also Spencer did not have the money to play the game. Then Spencer said” I don’t have that kind of money sorry” The rich man replies by saying” Don’t worry I’ll just put 10,000 dollars on the line my money lets play”.

Spencer and the rich man headed off the find a table to play a life-changing game of poker.

They both sit down and the rich makes the first move placing down a 5 of diamonds. After a lot of moves has been made they were down to a few cards left, all of a sudden the rich man makes a very wrong move and Spencer gets a Royal flush, winning the 10,000 dollar game of poker. Spencer jumps out of his seat of excitement in disbelief that he just won a life-changing game of poker. He gets up quickly grabs the money and runs off buying not a steerage ticket but a luxurious cabin ticket to New Zealand for himself. On the same day, he gets home and quickly packs his bags and sprints to the boat in such excitement. He boards the boat show his ticket to the crew and the crew shows him where to sit in the cabin. He finds his seat and sits for an hours time thinking it was going be a good life in New Zealand. On the boat, he finds a note that says “NEW ZEALAND IS HELL” but Spencer did not pay attention too much because he finds New Zealand as a  Mavoulos place. The boat trip was 3 days long and Spencer was having a great time in the cabin class because it was surrounded loads of food and you also had your own beds to sleep in. The cabin class was very luxurious for Spencer because he had come up from a very poor family.

The day has gone past and its the second day, Spencer was sitting in his bed when unexpectedly a huge thump came from the walls so Spencer went to check out what/Who did it or why it happened.

Spencer walked around right outside his cabin to find a note nailed in a wall saying “We all are targeting you when you arrive at your destination”. Spencer was a little bit shocked because he had so many plans in New Zealand but then this little note had ruined his mood. On that night spencer, hardly went to bed worrying about what will occur when he reached New Zealand.

Its day 3 the day where Spencer arrives in New Zeland. There are 30 minutes until Spencer arrives at his destination. He is still worried about that note from last night, wondering to leave New Zealand on the same day he arrives. The ship is nearly at New Zealand its insight, as New Zealand is getting bigger and bigger when insight Spencer heart is beating faster and faster.

The ship has arrived, strangers from the boat rush to pack their bags and get off the ship.

Spencer is so happy that he is here but is one thing that he has forgotten about and that thing is the note that he saw last night that shooked him. Spencer has got off the boat after he takes five in New Zealand *BANG* a bullet comes out of nowhere and strikes Spencer in the head leaving him helpless on the floor…..

Science

For my work, I had to work out the difference between Nuclear fusion and Nuclear fission.

Health (Drugs)

Taha Tinana (Drugs)

You need to research and explain how your topic affects physical well being. You need  to include the following

This is the drug that I'm going to be researching. (WEED)

How does this affect the body?

• Red eyes
• memory problems
• Impaired judgment 
• Increase dopamine release
• Increase or decreased Depression symptoms
• Increase or decreased anxiety
• Trouble developing brain
• Glaucoma relief 
• burning mouth
• Bronchitis
• celebrating heartbeat 
•  Phlegmy irritation
• The Munchies 

And much much more it is very bad to smoke.

THINK TWICE BEFORE TAKING THE RISK

Social studies

Slavery 

• Slaves needed something to do in the fields
• They were in the fields from sunrise to sunset 
• They would sing what they call work songs to keep themselves alert and entertained, but also to call attention to one another.

These songs tell stories of how the slaves feel at that moment, some has hidden messages. 

One of the slave songs <-- The link

Questions 

Explain the feelings that you get when you listen to the these songs?

The feeling that I get is mostly powerful and sadness 

What kind of information about slavery did you learn from these songs?

 That no matter how bad of a situation your are in you can always get out of it.

Do you feel songs today are similar, where they have hidden meanings or messages in their lyrics If so, What examples can you think of?

One of my example is xxxtentcion songs when you play it backwards your is hidden messages that relate to his death... 

Slave Songs: Spirituals

• African American Spiritual, usually with a christian religious theme, were originally monophonic and a Capella 
• The terms Negro spiritual, Black spiritual, and African- American spiritual, Jubilee, and African-American folk songs are synonymous.

Science Year 10

Aim:  I want to Investigate how to extract DNA from a kiwifruit

Research: Exacting DNA from a Kiwi fruit
Hypothesis:
I expect to complete the test the right way by following the instructions carefully.
And I also expect to ace this experiment.

Method: 

1. Cut the kiwifruit into cups and put it in a zip lock bag and mush it until it almost looks like pudding.
2. Fill a cup with hot water and salt.
3. Pour the saltwater mix into the ziplock bag and close it gently, Squeeze and move the salt water and kiwifruit mush together. Do this for 30 to 45 seconds.
4. Add dishwashing soap into the bag and gently mix the contents. try to avoid making too much foam.
5. Place the coffee filter in a glass cup, securing the top of the filter around the lip of the cup.
6. Pour the mix into the filter and let it sit until all of the liquids drip down.
7. Remove and discard the used coffee filter.
tilt the glass slowly and add cold alcohol down into the cup. You want the alcohol that is 2.5-5 cm thick.
8. The layer is set up, wait for eight minutes. You may see some bubbles and cloudy material moving around in the alcohol. This is the DNA pieces clumping together.
9. Use the wooden stirrer to start poking the cloudy stuff in the alcohol layer. Spin the stirrer it in place to start gathering the cloudy stuff.  

Equipment:

• Coffee filter
• Funnel
• dishwashing liquid
• salt
• zip lock bag
• glass cup
• Alcohol (Isopropyl)
• wooden stirrer
• toothpicks
• measuring cylinder
• beaker
• 1/2 spoon

PS: The link will take you to a banana instructions guide 
but it also works with a kiwifruit



Discussion: 
(S) Deoxyribonucleic acid is made up of molecules called nucleotides. Each nucleotide contains a phosphate group. 

(E) 

(X) This is how my experiment ended up looking like. It was a complete success.
When pulling out the DNA is was feeling snot after you pulled it out from your nose.
I am very proud to achieve this Experiment.



What could I do better?
I could have done better is decreasing the foam because the foam distracts the DNA.

What would I've done differently?
I would get hot water differently rather boiling it because boiling the water will take much longer.

I defiantly will do this again but with another fruit such as a banana, dragon fruit, pear, grapes etc...
overall I loved doing this experiment.
