Testing For Hydrogen Gas

Testing for Hydrogen Gas 

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

Method: 

1. Add your sample of metal to your test tube. Add 2ml of acid.

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

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

4. When you think the tube is full, Mr Heath should light the wooden splint.

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

Results:

It made a popping sound.

Discussion: 

When the reactants (Metal + Acid) mixed together it resulted in two products (Metal Salt + Hydrogen). Because we trapped the Hydrogen gas into the test tubes it started to heat up and bubble. Because of this we knew that it was ready to have the splint put into it. When the splint was put in the test tube it reacted with the Hydrogen gas resulting in the popping sound.

Conclusion:

The experiment worked because the end result was a popping sound. I wouldn't change anything.   

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.

Results:

Chemical Being Tested	Colour in blue litmus	Colour in red litmus	Colour in Universal indicator
Dishwashing Liquid	Blue	Violet	Green
Vinegar	Red	Red	Red
Toilet Cleaner	Red	Red	Red
Spray and WIpe	Indigo	Indigo	Blue

My Model Atom

Aim : To make a model atom.

Method -

1. Choose and atom to make ( one between Hydrogen and Neon ).

2. Work out how many proton, neutrons and electrons it has.

3. Assign protons and neutrons to a particular colour bead.

4. Get a ball of blue tac and stick the protons and neutrons to this to make your necleus.

5. Cut out the appropriate electron shells and draw on the electrons with vivid.

6. Connect the nucleus and electron shells with a piece of string.

7. Create a label to go above the model so people know what you have created.

Results -

Discussion -

- Atomic and mass number

- Number of protons, neutrons and electrons

- electrons arrangments

- 2 intresting facts

Conclusion -

- Did it work? 

Yes

- Would you do anything different?

Nah

3 2 1 R I Q

321RIQ is a new way we have been learning to reflect. The reason we are learning this is because we are trying to practise to reflect on our work. This is a cool new way for us to be able to reflect on all of the work we do. This is what 321RIQ should look like.

3 - Recall

2 - Insights

1 - Questions

-

Recall -

For Recall you have to write down 3 things you recall from either the perivous lesson on the lesson you just completed. The reason we do this is so you can remember what you have been completing.

Insights -

For Insights you need to write down 2 things you have learnt in either the previous lesson or the lesson you just completed. The reason we do this is so we can show that we learnt something.

Question -

For the Question part all you have to do is write a question to wither the teacher or someone else in the class that knows the answer, The question has to be something you didnt understand or something you want to know more about. The reason we do this is so we get a better understanding of what we have been learning.

Coraline Essay l Film Studies

Coraline is set at the Pink Palace where her and her family live, it is quite boring and dull and is raining a lot of the time. They live quite miserable lifes and don’t get along too well. I think the director has given the movie various different routes the movie could go along which has created a lot of excitement, he also uses quite a weird approach on the movie using a plot that nobody would have thought of. Coraline wishes that she could just leave and her wish does come true as she finds the “portal” to the “other world”.

There she meets the “Other Mother” cooking a breakfast ready made for Coraline. It is a very bright setting with heaps of joy and light. If this isn't already weird enough she has a set of buttons instead of eyes. The Other Mother is very friendly unlike her Mother in the original world and is very joyful, I think the director uses this light to make the watcher think as if they're Coraline and get them thinking that this world is very happy and joyful even though it is the complete opposite. Coraline enjoys a few days at her new found home. After staying in the other world for quite some time she notices a few weird things going on, the Other Mother dramatically changes moods if Coraline doesn’t comply or doesnt listen, hence showing the bad side of her personality and how she is not how she actually seems. 

Things gradually get worse and the hints keep popping up that something’s not right it creates a feeling of suspense. The Other Mothers stance first changes followed by the physical attributes and it gets to the point where she doesn't look human anymore and more spider-like, the lighting becomes very dark but also has neon colors incorporated to create a spooky feeling. She starts getting nasty and Coraline is very scared at this point. At some point in the movie the Other Mother (which now looks like a creature from outer space) has taken the key to get out of the other world and Coraline is faced with tasks to get it back, a big part of this is when she has to escape from the cell and save her parents. 

The movie is great and has one of the most intriguing plots in a movie, the mixed use of lighting, shots, sound and angles creates a feeling as if you are in the movie and is very thrilling. The build up of the movie creates an influential feeling of suspense which makes the movie just that one bit better. Overall the movie was a milestone in film and should be praised for the creative genius the piece of writing i've written here proves my statement and gives a strong backup towards the statement. I think they should possibly make a Coraline 2 with how good the first was.

Going from a cool, calm, collected person to a nasty, spider-like being is a big change in the story and is the main setup for the action toward the end.
