Marble dying

In textiles we have been doing dying experiments. Down below is photo of how mine went, it was super easy and fun. First we got a sheet of material, and wet it enough for it to be damp, then we added a few marbles and wrapped rubber bands around them to be secure. Once that was done we put in colours of our choice, I picked purple, blue and pink. I'm happy with my end result, as this was what I was hoping for. This was a fun activity to do and would be nice to show to others. 

Ocean dump

 

In social studies we have been learning about the ocean dump and climate change. We were told to make a news article about what caused this and the effects. Here is a link to a video explaining what kind of a world we have created, check it out. video

Corrosion

Corrosion 1

Aim: To investigate the factors that cause rusting in iron.

Equipment: Four test tubes, test tube rack, a bung, four iron nails, boiled water, tap water, salty water, cooking oil, calcium chloride.

Method: 

1. Label four test tubes A - D and place in a test tube rack.

2. Test tube contents: A = Iron nail and tap water 

                                  B = Iron nail and salty water

                                  C = Iron nail, boiled water, oil.

                                  D = Iron nail and calcium chloride. Sealed with a bung.

3. Leave the test tubes undisturbed for at least three days. 

Corrosion 2

(prevent rusting)

Aim: To investigate a number of techniques that may prevent rusting.

Equipment: Four test tubes, test tube rack, a bung, four iron nails, tap water, Vaseline gel, nail polish or paint, zinc pellets or magnesium ribbon.

Method: 1. Label four test tubes A - D and place in a test tube rack.

2. Fill all test tubes with equal volumes of water - enough to cover the nails.

3. Test tube contents: A = Iron nail

                                  B = Iron nail covered in Vaseline

                                  C = Iron nail painted with nail polish or paint

                                  D = Iron nail with a small piece of magnesium ribbon wrapped around it, or with zinc pellets added to the test tube. 

4. Leave the test tubes undisturbed for at least 3 days.

Conclusion: As you can see in the photo above the experiment worked successfully!

Climate change facts

 In social studies we are learning about the environment and what happens around the world. We went onto happy broadcast, where it shares information about what people are doing to help keep this planet healthy. here are a few I found. 

Anti-Vietnam war song

 War

The Vietnam war created chaos for a lot of people, so Edwin Starr and many others used music as their response, which gave this war its considerable impact. This song "War" was recorded first by the group Temptations but Edwin Starr's version caught more attention. Edwin's powerful soulful voice explains about why this war is pointless, and how we are losing innocent lives to it. 

(take a listen) Song

Lyrics

War, huh, yeah
What is it good for
Absolutely nothing
War, huh, yeah
What is it good for
Absolutely nothing
Say it again, why'all

War, huh, good god
What is it good for
Absolutely nothing, listen to me

Oh, war, I despise
'Cause it means destruction of innocent lives

War means tears to thousands of mothers eyes
When their sons go to fight
And lose their lives

I said, war, huh good god, why'all
What is it good for
Absolutely nothing say it again

War, whoa, lord
What is it good for
Absolutely nothing, listen to me

it ain't nothing but a heart-breaker
(War) friend only to the undertaker
Oh, war it's an enemy to all mankind
The point of war blows my mind
War has caused unrest
Within the younger generation
Induction then destruction
Who wants to die, ah, war-huh, good god why'all
What is it good for
Absolutely nothing
Say it, say it, say it
War, huh
What is it good for
Absolutely nothing listen to me

it ain't nothing but a heart breaker
(War) it's got one friend that's the undertaker
Oh, war, has shattered many a young mans dreams
Made him disabled, bitter and mean
Life is much to short and precious
To spend fighting wars these days
War can't give life
It can only take it away

Oh, war, huh good god why'all
What is it good for
Absolutely nothing say it again

whoa, lord
What is it good for
Absolutely nothing listen to me

it ain't nothing but a heart breaker
(War) friend only to the undertaker
Peace, love and understanding
Tell me, is there no place for them today
They say we must fight to keep our freedom
But lord knows there's got to be a better way

Oh, war, huh good god why'all
What is it good for you tell me
Say it, say it, say it, say it

huh good god why'all
What is it good for
Stand up and shout it nothing

Science - Making salts

Making Salts 

Aim -  To produce sodium chloride salt by carrying out a neutralisation reaction.

Equipment - 50 mL and 200 mL bealers, dilute HCI (hydrochloric acid), dilute NaOH (sodium hydroxide), 25 mL measuring cylinder, a glass stirring rod, spotting tile, universal indicator solution, tripod, gauze mat, bunsen burner, evaporating basin. 

Method - 

1. Using the measuring cylinder measure 10 mL of HCI and pour it into your 50 mL beaker. Add dilute NaOH a few drops at a time while stirring with the glass rod. 

2. Every 10-15 drops stop adding the NaOH and use the glass stirring rod to transfer a drop of the solution to a spotting tile. Test its pH using universal indicator.

3. Keep adding NaOH and testing the solution by repeating step 2. Ad you get closer to neutral you may need to test the solutoin after every drop. 

4. Pour the neutral solution into an evaporating basin and evaporate the water out of the solution using the equipment set up shown above. 

Beatles perspectives

Beatlemania

Perspective for -  

The main people who love The Beatles were the ladies, because The Beatles sang sexual or deep meaningful songs and the girls loved it. Not only was this something different but The Beatles were entertaining, and they created excitement. People went crazy over them, screaming, crying, throwing their panties, they did outrageous things.

Perspective against - 

During this chaotic event, the older generation didn't like the idea of what The Beatles created. They thought the songs they were singing were putting nasty ideas into their kids, things like sex, drugs, intense love, the parents only had passion for the simple songs. This new band was the talk, everyone loved them so who wouldn't want to see they perform live, the kids would go to their parents and beg to buy tickets to go, which then created another reason of why the parents didn't like The Beatles.
