Hokey Pokey

 Aim : To make hokey pokey using Sugar , Golden Syrup and baking soda . 

When the sugar and golden syrup combine with the baking soda it froths and makes carbon dioxide gas . That is why the hokey pokey has bubbles . 

Materials : 

  1. 2 tablespoons of golden syrup 
  2. 4 table spoons sugar 
  3. 1 Heaped teaspoon of baking soda 
  4. Pot 
  5. Tablespoon , Tea spoon 
  6. Bunsen burner 
  7. Grease proof paper 
Method : 

Put 4 tablespoons of sugar and 2 tablespoons of golden syrup in a sauce pan and melt 
Bring to the boil and simmer gently for 5 mins 
Add baking soda and stir vigorously
Put the hokey pokey on a piece of grease proof paper to cool 
 
The more sugar syrup is cooked the browner it becomes . If it is left cooking for to long your hokey pokey becomes burnt . 

Explanation : 

Why do we stir ? So the sugar doesn't burn 
Explain why the hokey pokey rises ? cause you added the baking soda

Lockdown 2021


Lockdown 2021

  • Government confirmed the Covid-19 variant infecting people in the North Shore was closely matched to Covid found in a recent returnee from Sydney in managed isolation.

  • “Now we can be fairly certain how and when the virus came into the country,Ardern said.        ↓↓

  • That person arrived on August 7 – meaning it was unlikely the disease had been spreading for weeks, as was earlier feared.

  • Five community vaccination centres in Auckland are closed today because staff have been diverted to help at Covid-19 testing centres.


Manurewa, Ōtara, Westgate, and Tamaki  are open for vaccination. 

The closed centres are Birkenhead, Highbrook, Pukekohe and Takanini. Almost all general practices remain open.


  • “Based on timelines, there are minimal missing links between this returnee and the cases in our current outbreak, and the period in which cases were in the community is relatively short.”

Yet the high number of locations visited by the community cases, and the infectiousness of the Delta strain, mean New Zealand is not out of the woods.

To Do!

  1. Highlight (in yellow), the suffixes in all the underlined words above.

  2. One of the underlined words also has a prefix. Which word is that? Unlikely 

  3. Remembering that a compound word is made up of 2 (sometimes more) base words (e.g. grandfather; into) find 5 compound words in the text above

i)     Highbrook                                  ii)    Birkenhead                     iii) Timeline 

 iv)        Outbreak                             v) Westgate 

5.  Highlight (in blue) capital/uppercase letters that begin proper nouns in the text (e.g. Auckland). Do not highlight capital/uppercase letters that begin sentences/statements/questions.

6. Highlight (in red) a quote from the Prime Minister (clue: you will spot speech/quotation marks). 

7. Based on the reporting about Covid, find your own words and write 5 sentences about how this lockdown has been for you. 

 

This Lockdown has been really tough because I'm stuck at home and I can’t go anywhere. Also it's really sad for those people who have covid and are dying from it . I have mixed emotions , so half of me is happy we are on lockdown but then half of me is not because I won't be able to see my friends or family . The weird thing is that we have to go on a zoom call with our class but it feels different because we normally don't do this and it just gives me mixed emotions .

Folk Tale

This week I read a folk tale story called The Empty Pot. A folk tale is a story that has been told for generations and has a moral or a lesson in it.

The Empty Pot story is about telling the truth and being honest. Ping was in a contest to win to be the Emperor. The Emperor gave the kids a cooked seed but they cheated and brought a plant, except Ping. Ping had tried growing his plant for so long he didn't have a plant to show the Emperor. Ping told the Emperor that his seed wasn't growing and then the Emperor told all the kids that he actually cooked the seeds, just to see if the kids would be honest because they needed an honest Emperor.  He became the Emperor because he was honest and truthful. Then at the end the boy came the Emperor.
