Experiment

How to make Hokey Pokey

What you need:
50g sugar, 1 table of water, 2 tablespoons of golden syrup, 1 teaspoon of bicarbonate soda

Method:

1. Put the ingredients except for the bicarbonate of soda in a saucepan and place on low heat.
2. Stir until all the sugar has dissolved. Raise the heat slightly so that it bubbles, and stir occasionally until you cannot feel any sugar at the bottom of the pan.
3. Take off the heat
4. Add bicarbonate of soda and stir
5. Watch what happens - it should all froth up with bubbles in a pan
6. Pour out into your tinfoil sheet
7. Allow cooling

Observations:

OURS DIDN"T WORK PROPERLY!

Metal Carbonates and Acid

Testing for Carbon Dioxide Gas

Aim: To show that carbon dioxide gas is produced when a metal carbonate reacts with acid
Equipment: Two boiling tubes, Delivery tube and bung, Bunsen burner, test tube rack, wooden splint, acid, metal carbonate, test tube tongs, safety glasses
Method: 

1. Light your Bunsen burner
2. Add a 'pea-sized' amount of metal carbonate into one of the boiling tubes.
3. place the boiling tube into a test tube rack. Ensure you have the bung and delivery tube ready
4. Add 5 mL of acid to the boiling tube and quickly insert the bung and delivery tube into the mouth of the boiling tube.
5. Holding the other boiling tube with your tongs, capture the gas produced as shown in the diagram below.
6. When you think the tube is full, your lab partner should light a wooden splint
7. Carefully remove the boiling tube from under the delivery tube, taking care to keep it facing upright
8. Insert the burning splint into the mouth of the test tube.

Observations:

We observed it becoming extinguished. CO2 was present as well. We did another experiment too. The outcome of this one was that the solution turned from colorless to cloudy. CO2 was present in this experiment as well

Experiment

Making a metal Oxide

Aim: 

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

Equipment: 

A piece of magnesium, Bunsen burner, Safety glasses, metal scissor tongs.

Method: 

1. Light your Bunsen burner.

2. Hold your piece of magnesium in the scissor tongs. Ensure   you are  holding onto the very tip of the magnesium

3. Place the other end of the magnesium into the Bunsen flame

4. When the magnesium beings to burn, do not look directly at it, as the light emitted can permanently damage your eyes.

Observations:

Before the reaction, it was a shiny metallic luster, But after the reaction, it turned into a bright white light.

The equation of this reaction:

Magnesium + Oxygen ------- Magnesium oxide  

Metals and Acids

Testing for Hydrogen Gas:

Aim:
To show the 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, safety glasses.

Method:
1. Light your Bunsen Burner
2. Add your sample of metal to your test tube. Add to 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 test 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 we placed the metal in the acid it began to sizzle a bit creating smokes. After putting the other test tube over it nothing really was occurring. We lit the fire then put it in the test tube. Gas started forming on the rims of the test tube. After displaying that, there was a loud bang-like sound. That's when you know it works.

Palaeolithic Age

PALEOLITHIC STONE AGE:

Our current new topic is based on Paleolithic and Neolithic. I discovered about the evolution of how things were constructed to how they were used.  I found out the way their weapons were used for or what they were made out of (e.g They would use rocks and intensify the tips of the rock to create a weapon.)  I have also learned that the people of the Paleolithic stone age gathered their food and were only able to take so much. I have indeed learned a lot while doing the study on this specific topic.

Interviews

Are you addicted to your phone?

 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.

Making Salt

MAKING SALT

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

Equipment:
50ml and 200ml beakers, dilute HCI, dilute NaOH, 25ml measuring cylinders, a glass stirring rod, spotting tile, Universal Indicator solution, tripod, gauze mat, Bunsen burner, evaporating basin

Method:
1. Using the measuring cylinder measure 10ml of HCI and pour it into your 50ml beaker. Add dilute NaOH of few drops at a time while stirring with a 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. As you get closer to neutral you may need to test the solution 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.

Traditional Music

Aotearoa -Stan Walker

What style of music is this? Who this sung by? Why did they write it?  
This song specifically is a Pop song. It is sung by Stan Walker but it is also sung by other artists.  This song was written to celebrate Maori language week.

What did you like about the music?
I liked the fact that it transitions from Maori to English and there were heaps of singers.

What did you like about the video?
That fact that it was filmed in New Zealand also fitted well with the lyrics they were singing

Find out what the songs about, can you find a translation of some of the lyrics?
This song is about New Zealand staying strong as we are one.
No te whenua o te Atua tatou - We come from a land of God.

Neutralisation

Neutralisation:

A chemical reaction occurs when you mix together an acid and a base. The base conceals out to the effects of the acid. The reaction is called a neutralisation reaction because a neutral solution is made when you add just the right amount of acid and base together.

Aim:                           
To observe a neutralisation reaction.

Equipment: 
A test tube, test tube rack, 1 mol L-1 Na2CO3 (sodium carbonate), 1 mol L-1                                        HCI (hydrochloric acid), dropper or dropper bottle, Universal Indicator solution.

Method:                   
  1. Add approximately 1-2 mL of Na2CO3 and place the test tube into the test                                    tube rack. Add 3 drops of Universal Indicator solution
  2. Using a dropper bottle, add HCI drop by drop. Be careful because adding                                          even a small amount of extra acid can mean you'll miss the neutralisation point

Observations:            
That the Universal Indicator turned purple-blueish when it was placed in the                                            Ammonium Hydroxide. Bubbles then formed around the rim of the tube as we                                      added the Sulfuric Acid, changing colour from bluish-purple-yellowish-red-                                            pinkish. 


We then did some experimenting to try and make different colours: 

Debation

 Topic: "Space exploration is a waste of time and money"

I STRONGLY AGREE:
In my opinion I agree because millions of dollars are spent on every year on space agencies and equipment, but how does it benefit us. Money benefits can go to something worth the long run. It could be put to homeless shelters, education, poverty. These are just some of many things we can do. Furthermore, a lot of this brings us irrelevant to our daily life. Why bother making a zero-gravity pen when a pencil is fine.

Music for Matariki

Matariki signals the Maori New Year. It is a time of celebration in New Zealand that begins with the rising of the Matariki star cluster (the Pleiades or Seven Sisters).

Traditionally Matariki was celebrated by gathering with whanau and reflecting on the past. Offerings were made to land-based gods who would help provide good crops, and new trees were planted to signal new beginnings.

HOW DO COMMUNITIES RECOGNISE MATARIKI?

Matariki is a good opportunity for Maori to share their stories and culture with the wider community, and many events and activities are planned throughout the country to share and celebrate Matariki. Some common events and activities include:

• Concerts
• Art and Craft Workshops
• The sharing of myths and legends
• Astronomy Workshops
• Hangi and Feasts
• Dawn Ceremonies
• Family Days
• Cooking Demonstrations

Testing pH

Aim:                         To test the pH range of household chemicals.
Equipment:               A variety of household chemicals, spotting tile, red litmus paper, blue litmus paper, Universal indicator solution, safety glasses
Method:                    1. Add a few drops of each chemical to a spot on your spotting tile. If a substance is solid or powered you will need to mix it with a few drops of water before testing
                                 2. Test the chemicals with litmus paper
                                 3. Test each chemical with a few drops of Universal indicator. 

Results:

Chemicals being tested	Colour in blue litmus	Colour in red litmus	Colour in Universal Indicator
Harpic Active Fresh (Toilet Cleaner)		It turned blue	It turned yellow
Pledge clean and dust	It turned purple		Orange
Easy off BAM Bleach Hygiene	Remained blue	Blue	Purple with a hint of green
Dettol Multipurpose Cleaner		Remained red	Yellow
Dishwashing liquid	Remained the same		green

Universal indicator:
The universal indicator shows us how strongly acidic or alkaline the solution is. It also has many different colour changes, from red for strong acids to dark purple for strong bases,In the middle neutral pH 7 is indicated by green.


Litmus indicator:

Litmus indicator solution turns red in acidic solutions and blue in alkaline solutions. Litmus also comes in paper form. Blue litmus paper will turn red in an acidic solution and remain blue when added to an alkali solution. Litmus does not tell you how strong the solution is.

Tech and Change

Define Technology:

                                   the application of scientific knowledge for practical purposes, especially                                     in industry.

What the slide are about:
                                  I have created this prezi to explain and compare the difference with                                                      technology now, and how technology has changed the way we do things.
                                  Tech and Change Presentation (not quite finished)

For Example:
                                  Television only came with two colours (black and white)

Now we watch television with colour

This is just one of many things that technology has done to change what we do now or how we do/use it
