Lock down scavenger hunt

 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? 

  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 about Covid 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. 

 

My lockdown was very boring because all I would do is just lie down and play Call Of Duty. Our zoom calls were different because we were usually so close but I felt sad because I wasn’t with my friends at school. But I kind of liked lockdown because I got to spend time with my family and home and get closer to each other


Acids

 What makes something acid? An acid is a substance that donates hydrogen ions. Because of this, when an acid is dissolved in water

Properties of acids? Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current

What is an acid? A substance with particular chemical properties including turning litmus red, neutralizing alkali, and dissolving some metals; typically, a corrosive or sour-tasting liquid of this kind.

what are 3 examples of acids? 

  • Hydrochloric Acid.
  • Sulfuric Acid.
  • Nitric Acid.

what is the most famous indicator? Moving Averages.

what does pH stand for? Power of hydrogen

How many numbers are there on pH scale? 1-14


Aim: To make red cabbage pH indicator for use on different household chemicals


Materials

  1. Red Cabbage

  2. Beaker

  3. Bunsen Burner

  4. Pipette

  5. Sodium Hydroxide

  6. Hydrochloride acid

  7. Test Tubes

  8. Paper towel

  9. Test tube rack

  10. Water

  11. floor cleaner

  12. dish washing liquid

  13. vinegar


Steps

  1. Chop up the red cabbage into small pieces. Place in a beaker and cover with a small amount of water.

  2. Bring the solution to the boil using a Bunsen burner and then turn off the heat. Let it sit to cool down.

  3. Pour the cabbage water through a paper towel into a beaker. The dark purple liquid in the jar is the pH indicator liquid.

  4. Suck up the indicator into a pipette.

  5. Use the cabbage indicator to test the acidity of the different household liquids by slowly putting a drop at a time into the test tube.
