HART piktochart

We are learning about the anti-apartheid organisation named H.A.R.T. (Halt All Racial Tours). We are learning about it because it shows New Zealand's connection with Apartheid South Africa. We learnt of it when we started learning more about Apartheid South Africa when we were watching the film 'the power of one'.

Making a Metal Oxide

Aim:
To make a metal oxide and observe the difference in properties of the product compared to the reactants.

Magnesium: (Mg)
Before burning it, it was a metallic lustre then when put over the Bunsen burner it turns into a bright white light.

Iron: (Fe)
Before burning it, it was a metallic lustre and then when put over the Bunsen burner it turned into black.

Copper: (Cu)
Before burning it, it was a bronze/brown colour and then when put over the Bunsen burner it turned into dark purple/black.

The equations:
Magnesium + Oxygen ---> Magnesium Oxide
Iron + Oxygen ---> Iron Oxide
Copper + Oxygen ---> Copper Oxide

I wonder if aliens exist.

From this website I learned that there have been unexplained sightings for centuries. From crop circles to skulls that are bulging on the head that were found on earth. Many UFO (Unidentified Flying Objects) have been seen over the centuries. I think some could be hoax though. Even in 'The Madonna with Saint Giovannino ', other wise known as the UFO painting, A man and his dog can be seen in the background staring at a flying disk. There are also cave painting that have indicated to alien existence. Many astronauts have recorded sightings as well. Buzz Aldrin, who was aboard the Apollo 11, recorded that he saw something flying next to them and he thought it was the final detachment until mission control confirmed it was 6000 miles away from them. Also Bill Clinton spoke continuously on the existence of aliens and speaking his opinions on the 'independence day'. So there is a lot of evidence leading up to it and I think alien existence could be a very high possible theory.

Now this makes me wonder if they will ever strike us and are just waiting for a prime opportunity.. ??

Testing for Hydrogen gas

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

Method:
1. Light your Bunsen burner.
2. Add your sample of metal to your test tube. Add 2 mL of acid.
3. Carefully invert the boiling tube above the test tube containing the metal and acid.
4. Hold the test tubes together for a few minutes, allowing time for the inverted boiling tube to fill with gas.
5. When you think the tube is full, your lab partner should light a wooden splint.
6. Carefully, but quickly, tilt the boiling tube full of gas upwards and insert the burning splint into the mouth of the test tube.

Observations:
When you insert the splint into the boiling tube it produced a high pitch noise and put the fire out.
I could tell a chemical reaction was occurring in the test tube because when you put the sample of metal (magnesium ribbon) in the hydrochloric acid it fizzed up and produced hydrogen.

Phone Addiction

Recently we've been looking at how technology has changed the way we do things. 

Analysis has shown that young people specifically spend more time on their device. As a group, we interviewed a few people to see whether they were addicted to their phone. We surveyed a diversity of different personalities. Throughout the videos, each individual spoke about if they are addicted to their phone and how many hours they were on it. Majority confessed to being addicted to their devices and the number of hours they were consuming. Based on our little investigation we found out that the being addicted to your phone was common. We also observed that 3 out 5 people said that they wouldn't survive without their device.

Essay Practice on 'The Power of One'

Floating houses

I gaze at the flock of crows passing by. Then one lands on the window sill and we compete in a staring contest. Finally I win and the bird flies away to join the others. I stare after them while they disappear into the misty clouds. I’d rather look up then down. I can’t look upon the world we destroyed. The cracked concrete, the patches of earth, the boulders, the floating streams of murky water. Then the destruction.. The floating lifeless bodies and animals that died of suffocation. Even looking side-wards is annoying. Looking at the transcending roots connected to trees just floating there. We’ve lost all gravity and oxygen in our atmosphere. We should’ve known.. We would be our own destruction. No one’s ever gone to recover the bodies. Well there’s not much time anyways. I can feel myself start to try inhale as much air as possible. With no oxygen source I am slowly dying. But i’m okay. I'm proud of myself for shoving my wife and children into the last shuttle to safety. Apparently the government has made a space station for those that are lucky. They predicted it but didn’t warn us. They were screaming for me but at least they are okay. Everything will be alright. And with a tear and a smile my lungs collapsed and my heart stopped beating. At least I died in this house that I proposed to my wife in, watched my kids grow in, i’m fine with dying in this floating paradise.

Making Salts

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

Equipment:
50 mL and 200mL beakers, dilute HCI (hydrochloric acid), dilute NaOH (sodium hydroxide), 25mL 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 NaoH and use the glass stirring rod to transfer a drop of solution to a spotting tile. Test its pH using Universal indicator.

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

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