Today we mapped out where different things were in New Zealand

Here we have a piktochart of New Zealand food history and how its changed over time. I choose these ten historic that shows how that we use food

The second circuits we did only one of the bulbs lit up

How has writing changed form of technology changed over time

The earliest writing systems evolved independently and at roughly the same time in Egypt and Mesopotamia, but current scholarship suggests that Mesopotamia's writing appeared first. That writing system, invented by the Sumerians,emerged in Mesopotamia around 3500 BC.

No, you haven't just read the plot to a Game of Thrones spin-off - it's part of a massive conspiracy theory that members of the Flat Earth Society believe is orchestrated by Nasa and multiple international government agencies. 

Success in sports is all about winning

We have been learning about the technical and how its changed from the stone age to the present.

1. Aim: To investigate the factors that cause rusting in iron
2. Equipment: Four test tube, test tube racks, a bung, four iron nails,boiled water,tap water,salty water, cooking oil,calcium chloride.
3. 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.

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.

Testing for Carbon Dioxide Gas

Testing for Carbon Dioxide Gas

Aim:To show that carbon  dioxide  gas is produced when a metal carbonate react with acid.

Equipment: Two boiling tubes,delivery tube and bung,Bunsen burner,test tube rack,wooden splint, a bottle of acid,small  amount of  metal carbonate, test tube tongs, safety glasses.

Method: 1.Light your Bunsen burner.

2.Add a 'pea-sized' amount of the metal carbonate into one of the boiling tubes.

3. Place this boiling tube into a test tube rack.Ensure you have the bung and delivery tube ready.

4.Add 5mL 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 

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.

Public art is a waste of time and money

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.

Equation of this reaction:
Magnesium + Oxygen ------- Magnesium oxide  

Testing for Hydrogen Gas

Aim: To show that 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 2ml 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 parent should light a wooden splint.
6.Carefully, but quickly, tilt the boiling tube full of as upwards and insert the burning splint into the mouth of the test tube

Observations: It will make a popping sound

Those are everyday things that have changed over time

Testing pH

To test the pH of a range of household chemicals 

A variety of household chemicals,spotting tile,red litmus paper,blue litmus paper,Universal indicator solution,safety glasses

1.Add a few drops of each chemical to a 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.

2.Test the chemicals with litmus papers

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

This term we focused on Human rights and slaver.
we learnt about Harriet Tubman and about her life.
We also read a book about a true story about this kids called Iqbal
and how he was a child slave and how he lost his human right

1. Mush the banana in the resealable bag for about a minute until all the lumps are gone and it almost looks like pudding.
2. Fill a cup with the hot water and salt.
3. Pour the saltwater mix into the bag. Close the bag and very gently squeeze and move the saltwater and banana mush together. Do this for 30 to 45 seconds.
4. Add the dishwashing soap into the bag and gently mix the contents. Try to avoid making too much foam.
5. Place the coffee filter in a clear glass cup, securing the top of the filter around the lip of the cup.
6. Pour the mix into the filter and let it sit until all of the liquid drips down into the cup.
7. Remove and discard the used coffee filter.
8. Tilt the glass and slowly add cold alcohol down the side of the cup. You want the alcohol to form a layer on top of the banana mix, staying separated, so be careful not to pour it too fast. Make a layer of alcohol that is 2.5-5cm (1-2in) thick.
9. After the alcohol layer is set up, wait for eight minutes. You may see some bubbles and cloudy material moving around in the alcohol. This is the DNA pieces clumping together.
10. Use the wooden stirrer to start poking the cloudy stuff in the alcohol layer. Spin the stirrer it in place to start gathering the cloudy stuff. When you are done, take a closer look at the stuff on the stirrer. You are looking at DNA!

In social studies we have been learning about Harriet Tubman and what she did as a slave

Intro

Arthritis

Arthritis

The term arthritis refers to about 120 different diseases that can affect the joints, muscles and other soft tissues. The three most common forms are osteoarthritis, fibromyalgia and rheumatoid arthritis.Osteoarthritis is the most common type of arthritis. When the cartilage – the slick, cushioning surface on the ends of bones – wears away, bone rubs against bone, causing pain, swelling and stiffness. Over time, joints can lose strength and pain may become chronic. Risk factors include excess weight, family history, age and previous injury (an anterior cruciate ligament, or ACL, tear, for example).
