Climate change – Term 4

  1. What is climate change?

Climate change is the long-term change in weather patterns, as the strength of the sun and the amount of gases change over time.

 

  1. What is causing climate change/global warming? (~50 words)

Humans cause climate change because we produce carbon dioxide then the carbon dioxide makes it way into the atmosphere when the carbon dioxide gets into the earth’s natural greenhouse effect by trapping all of the heat then that natural greenhouse effect starts to break and it doesn’t work that way its meant to witch then it makes the climate hotter 

 

  1. In 2019, the “school strike 4 climate” movement started in Aotearoa. It’s still continuing today. Why do ākonga (students) throughout Aotearoa and globally want to go on strike from school and protest? (~100 – 150 words)

 

The school students all over the world wanted to protest because they believed that we need to change. climate change is caused by human actions that are not that good, like burning fossil fuels, which trap heat in the Earth. In 2019, Aotearoa students started the “School Strike 4 Climate” movement to demand action. They worry that warmer temperatures will lead to more pests and diseases, harming health and farms. Students want immediate action to protect the planet. Their students want to change for the better than what they were protesting for.

 

 

Safety and Medicine

4 key points from the video 

  • storying it correctly
  • check expiration date
  • keep it out of reach of children
  • take the medication safely

 

ways a teenager can be safe with medicine 

Ask your parents before you take your medicine

Take only your prescribed medicine unless over-the-counter

Read direction

Only take the suggested dose

Keep track of time and how many and when you’re taking the medicine

 

Pe

  1. You can play pickleball singles or doubles
  2. Only the server scores a point
  3. The first server is chosen at random, usually by coin toss
  4. The ball needs to bounce once per side after the serve 
  5. Only underhanded serves are allowed for volley serves
  6. You have to serve behind the baseline
  7. The ball has to stay in bounds
  8. The game ends at 11 or more points 

Tests With Magnesium 

What are the different experiments you completed, we did the Hydrogen pop test, Buring magnesium

 

Hydrogen pop test

We did added the hydrochloric acid and the magnesium to the smaller test tube and added the bigger test tube around the top and waited awhile then took the bigger one off and set the stick alight and put the stick in the big tube and heard a loud pop

 

Burning magnesium

We put a piece of magnesium on a pair of tongs then put the piece of magnesium on top of the bunsen burner then we watched the magnesium burn and turn into a bright white light then we took it off then put the piece of magnesium in the bin.

 

Learn How To Make Universal indicators

  1. Aim: why did we do the experiment?

I want to learn how to make and acid-base indicators using everyday substances

 

  1. Equipment: what did you use for your experiment?
  2. Red cabbage
  3. beetroot
  4. tea turmeric
  5. cranberry juice
  6. beaker
  7. water
  8. Heating plate
  9. test tube rack
  10. safety glasses
  11. hydrochloric acid
  12. base
  13. Pipepet

 

  1. Method: what steps did you complete to get your results for your experiment?  Use slide 100 to help
  2. Chop the cabbage into small pieces until you have enough to fill the small beaker
  3. place the cabbage into the small or large beaker then add boiling water
  4. then keep boiling it over the heating plate until it re-boiled
  5. until the color has seeped out
  6. repeat the steps with the beetroot
  7. then with a pipet get some of the beetroot juice
  8. add a little test tube rack fill only to test tubes
  9. then add some acid and base to each of the test tubes

 

 

  1. Results: Pictures 

 

  1. Discussion: starting discussion questions (you can include more detail)
    • What colour did each indicator change in an acid vs. a base? My group did the beetroot it started off by being a deep red but once we added the base it was still red just a lighter red then once we added the base it turned an orange colour.

      • Were some indicators better than others – if so, why do you think this is? Yes because some of them changed better coulers than others and if it changes color by a lot of them it means it worked. the cabbage showed that I could find out more information about the pH level because the colour changed better with gives be more information also about the cabbage indicator.

—Photo of the cabbage testing with both the base and when the acid mixed together. 

 

  1. Conclusion: starting conclusion questions (you can include more detail)
    • did all your experiments work – if they didn’t, why? yes they did they worked because it changed colour when the acid and base were added.
    • What could you do to improve next time? Maybe try adding more acid to the beetroot and more base as well.boil it longer and experiment with more indicator 

Testing pH – Science

  1. Aim: why did we do the experiment?

we did the experiment to test how the litmus paper and learn how the chemicals react to each other. 

  • Equipment: what did you use for your experiment?
  1. spotting tiles 
  2. dropper pipette 
  3. red litmus paper 
  4. blue litmus paper 
  5. Universal indicator solution 
  6. safety glasses 

 

Method: what steps did you complete to get your results for your experiment? 

  1. Get your equipment. 
  2. Add a few drops of each chemical to your spotting tile. if a substance is solid or a power you will need to mix it with a few drops of water before testing 
  3. Test the chemicals with litmus paper. 
  4. Test each chemical with a few drops of universal indicator. 

 

  1. Results: Pictures 

 

  1. Discussion: starting discussion questions (you can include more detail)
    • Why did different household chemicals change different colours? because the chemicals in the hose hold items and how they react to the universal indicator. It also depends on whether it’s an acid or a base. The different ph levels.
    • Use following words in your answer: acid, base, neutral
    • How did you know if these chemicals were acidic or basic? we knew if it was acidic or basic because of the blue and red litmus paper if it turned red it would be an acid and if turned a blue/purple colour it was a base. 

 

  1. Conclusion: starting conclusion questions (you can include more detail)
    • did all your experiments work – if they didn’t, why?  they all worked pretty well.
    • What could you do to improve next time? Try not to use so much of the Universal indicator solution because if I put too much it changes color to a green-blue colour.
