Neutralisation

Neutralisation


Aim: To observe a neutralisation reaction.


Method: 

  1. Get a test tube rack, 6 test tubes, acid, base and universal indicator.

  2. Fill 4 test tubes with 3mL of acid.

  3. Fill 2 test tubes with 3mL of base.

  4. Add a squirt of universal indicator to each.

  5. Add different amounts of acid and base to make the colours of the rainbow (ROYGBI)


Results: 





Discussion: 

We started with 4 red test tubes and 2 blue test tubes, but by the end of the experiment we ended up with  colours of the rainbow (ROYGBI). We did this by neutralizing some of the acid by adding base into it to make orange, yellow, and green. For the 1 of the base we add acid to make it a lighter shade of blue. 


Conclusion:

This experiment did work because we were able to neutralise the acids and bases to make the colours of the rainbow.

The Beatles

 Today I will be writing about the song, All My Loving written by The Beatles in 1963. 

Here is a video of what the song sounds like:


Here are the lyrics too: 

Close your eyes and I'll kiss you
Tomorrow I'll miss you
Remember I'll always be true
And then while I'm away, I'll write home everyday
And I'll send all my loving to you
I'll pretend that I'm kissing the lips I am missing
And hope that my dreams will come true
And then while I'm away, I'll write home everyday
And I'll send all my loving to you
All my loving I will send to you
All my loving
Darling, I'll be true
Close your eyes and I'll kiss you
Tomorrow I'll miss you
Remember I'll always be true
And then while I'm away, I'll write home everyday
And I'll send all my loving to you
All my loving I will send to you
All my loving
Darling, I'll be true
All my loving
All my loving
Ooh
All my loving I will send to you

What was the song about?

The song is about Paul McCartney going on tour and missing his girlfriend at the time, Jane Asher. It talks about how he will remember his girlfriend and how they kissed. It talks about how he will miss his girlfriend when he leaves and that he will write to her while he is away. It also talks about how he will be true to his girlfriend, meaning he will be faithful toward her and not be with another woman. Lastly, it states he will send all his love to his girlfriend too. 

How does it sound different from songs in the 1940's?

All My Loving, along with the majority of other Beatles songs caused extreme controversy and anger among the older generation. This generation didn't like the challenge from the youth and breaking of the status quo. These songs sexualised women, something which had never been seen before The Beatles and the Swingin' 60's.

The songs were essentially the voice to the younger generation, who felt repressed and therefore wanted to break away from the traditional ways of their parents. They wanted to break away from traditional clothes, music and language. 

The parents of these young girls were appalled and disgusted that songs were being sung about them. They didn't like these sexualised songs which had started spreading like wildfire, making their children, especially daughters go crazy. 

Songs in the 1940's were polar opposites to those in the era of The Beatles. For example, Swinging on a Star by Bing Crosby (1944) was about animals and how they looked, so they differed, A LOT.

Testing PH Experiment

Testing pH


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


Method:

Add a few drops of each chemical toa 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.
  1. Test the chemicals with litmus paper.

  2. Test each chemical with a few drops of Universal indicator.
