Discovering Chlorophyll’s Glow
For this experiment we use leaves, mortar and pestle and iso-propyl-alcohol.
The way we got chlorophyll from the leaves is we ripped them up then we put them in the mortar and pestle and added the iso-propyl-alcohol then we crushed it up with the pestle and after a while it came into a green fluid.
When the UV light hit the chlorophyll it turned a blood red, so it was a chemical reaction.
When the UV light is placed next to the chlorophyll solution, electrons are promoted from the S 0 state to the S 2 state.
A problem I faced was crushing the leaves to make the chlorophyll come out. Another problem was keeping everything in the Mortar and Pestle.
What I found interesting was when the UV light hit the chlorophyll the change in the colour.
I also found it interesting that the Iso-propyl-alcohol could make the chlorophyll come out.
This has helped me understand that chlorophyll is green.
That Chlorophyll turns red when UV light is shined on it.
Lastly, this helped me realize that you can use a mortar and pestle to crush up leaves and iso-pro-alcohol to make the chlorophyll come out.
Chlorophyll as u can see some are different colour this is because of the leaf colour
–This is what happens when chlorophyll gets hit with UV light.
Maori Traditions
Traditions are a thing that has been going on for thousands of year past down from generation to generation where they celebrate it for their culture
We maoris still use hangis to cook to keep it alive and so we have something to represent our culture. This represents our culture because it’s how we cook our meals.
We celebrate our Matriki culture because it’s a celebration that leads us into a
new year and it is a time to spend time with your family and plant trees. We also have a public holiday so everyone can go off work to spend time with their family. On matariki night everyone goes out to the beach or somewhere nearby so we can light fireworks, see the matariki and have a good time with family.
We eat hangi, boil up, mutton bird, and kai moana. We eat this kai because in New Zealand we love hunting, fishing and diving. So we would always dive for kina and oysters, anything we can get from the ocean we would eat. We also love hunting so we would hunt for mutton birds and pigs.
–Mutton Bird
In our Maori culture you may see a lot of people with a green necklace or a white necklace. These are called Pounamu and Taunga. It is a treasure that our family members have either given to us or have passed down to us. Our Taunga are very special to us because they hold a lot of spiritual and cultural meaning.
We have a traditional dance called the Haka. The first hakas were created and performed by different Māori tribes as a war dance. It is an ancestral war cry. It was performed on the battlefields for two reasons. Firstly, it was done to scare their opponents; the warriors would use aggressive facial expressions such as bulging eyes and poking of their tongues.
our culture is got a lot to do with kai moana/seafood
Kai moana is important because it helps with a lot of things
In our culture. Kinas are really good for growing plants
