Fire extinguisher test - Science

 Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid.

Method:

1. Add a pea sized amount of the metal carbonate into one of the boiling tubes.

2. Place this boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready.

3. Add 5 ml of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.

4. Holding the other boiling tube with your tongs, capture the gas produce in the other test tube.

5. Wait about 1 minute so the tube will be full and then get your partner to light the wooden splint.

6. When the test tube is full of gas, then carefully remove the tube from underneath the delivery tube.

7. Then carefully place the burning splint into the test tube.

Result: This experiment lead to the gas we made by adding hydrochloric acid and sodium carbonate to produce sodium chloride + oxygen + water, this gas cause it to put the lit splint out.

Discussion: We used hydrochloric acid + sodium carbonate = Sodium chloride + oxygen + sodium chloride to create this gas.

Conclusion: It did work it was to show what gas puts out fires like a fire extinguisher uses the same type of gases we used to put out the flame on the splint.

Water pollution - Social studies

In social studies the last couple weeks we've been watching videos and researching information about world wide problems including the great pacific garbage patch and sea problems/pollution etc, and also how one guy got inspired to try help.

The great pacific garbage patch is a massive patch of garbage it ranges from North America all the way to Japan. The great pacific garbage patch is made of plastic debris which is basically plastic things that get dumped or swept into the ocean.

Their was also a guy called Ali who got inspired to start being more sustainable in his life and try help with all these sea problems. He got inspired because he had realised how much it was effecting our planet and especially our sea life which also effects us.

Testing for hydrogen gas - Science

 Aim - To show that hydrogen gas is produced when a metal reacts with acid.

Equipment - A test tube, a boiling tube, bunsen burner, wooden splint, a bottle of acid, a piece of metal and safety glasses.

Method -

1. Add your sample of metal to your test tube, then proceed to add your 2ml of acid.

2. Carefully invert the boiling tube above the test tube containing the metal and acid.

3. Hold the test tube together for a few minutes, allowing the time for the inverted boiling tube to fill with gas.

4. When you think the tube is full, Mr Heath came around and lit the splint with a lighter.

5. Carefully but quickly tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Discussion: We knew it was ready to place the lit splint in the test tube, when we had left the acid and metal in for 1 minute or a minute and a half, because it had started to heat/boil and release the gas and steam. 

We tried this experiment, twice for the first one we used hydrochloric acid but the result wasn't what we wanted we then tried it with a stronger acid known as sulfuric acid and the result became better.


Conclusion: This experiment did work due to doing all of this it caused it to make a popping noise when the lit splint was placed into the hydrogen gas, you had to place it in their fast and carefully for a better and louder result.

Against/for the tour Beatles - Social Studies

Their were two different perspectives of the Beatles world tour, their were a large group of teenagers especially girls that were mostly for the Beatles world tour, but a majority of the older generation were against this situation.

Against the tour 

  -  A majority of the older generation of New Zealanders were against the Beatles world tour, due to the    Beatles lyrics being more sexualised towards the young teenage girls. But not only them sexualising        them but more encouraging them for sin in their life.

- Also a lot of people were against the tour not only cause of their choice of lyrics, but the way their were     outrageous majorities of crowds every where the Beatles went and a lot of the police had to restrain            girls from the Beatles so they had room to move around from place to place with big fences holding the     young teenage girls back.

For the tour 

 -  Despite the fact their was so many people against the Beatles world tour. A lot of the younger generation especially a massive majority of teenage girls were so much more for the Beatles world tour, because these young girls were so hypnotised by their looks and choice of song lyrics due to them never hearing anything like this in their lives before. It made these young girls fall for them fast because it was something new and different that they hadn't experienced before.

Hey Jude - The beatles

These are some of the lyrics from hey Jude sung by the Beatles -

Hey Jude, don't make it bad.


Take a sad song and make it better.
Remember to let her into your heart,
Then you can start to make it better.
Hey Jude, don't be afraid.
You were made to go out and get her.
The minute you let her under your skin,
Then you begin to make it better.
And anytime you feel the pain, hey Jude, refrain,
Don't carry the world upon your shoulders.
For well you know that it's a fool who plays it cool
By making his world a little colder.
As you can see by the lyrics it is about a heart break and they were trying to make a positive outlook on a sad situation. By writing a song about his heartbreak and saying to just let it go and not get down and out about it, but to be more positive about the situation. 
The older generation didn't like the fact they were influencing relationships, but also sexualising them. But compared to the music back in their days it was more innocent and random. So when the Beatles started realising music it was a great shock to the world and the older generation, but to the younger generation it was soul grabbing and freeing for their body. It was a revolution for history, people were mesmerised by not just their songs but them as people too.

Testing ph - Science

 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 and safety glasses.

Method:

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

2 - Test the chemicals with litmus papers blue and red.

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

Discussion: 

When we used toilet cleaner with the blue litmus it turned the litmus red instead of blue, this shows us that toilet cleaner is an acid because red shows that its a acid because it is at the bottom of the ph scale also known as 1 . But when we used universal indicator it went yellow/orange which is just before green on the ph scale so this could be from 3-5.

When you test blue or red litmus paper it can only turn from an acid or base no in between so either blue or red. But if you were to use universal indicator it could go from any scale of the ph scale so it could be neutral or from anywhere between 1 - 14.

Results:
