Art: Street Art

in art were researching and choosing a piece of street art that is located in Christchurch, and writing down something about it at what is resembles in your mind. The one I chose located near Battersea street and Colombo street, circled in the map below.

The art looks like it rocking out to some pretty good music and he's screaming out. and the rocking power is seeping into reality as the vibrant cool colour complement this piece of art. the other reason why I chose this one because I like the colours. The streaming of whites and blues from his eyes and the blue light beaming from his mouth it looks like he's attacking someone or trying to escape.

The second piece I chose is an intriguing one to me that relates to japan and the reds and the pinks stand out to me the most on the white background with the samurai of some sort standing in the middle with carrying his sword and hilt. I like how the character/person standing there is in black in white it makes the colours in the background to be seen in a different light of some sort. (I don't know how to explain it properly.)

Lastly is this interesting piece with a whole variety of colours, of many black thick lines going all over the place. it takes a while to figure out what you're looking out with all the many different things that are included in the image. the pinks, blues, oranges, yellows just seem all over the place.  I took awhile admiring how much detail was put into it.

SOST: How had tech change the way we do things?

Science: Copper Coin experiment

In science, we are doing an experiment using a coin. The two changes that should be seen is the copper turns a silver then gold. these metals combine together to create brass.

Instructions

- Clean coin in salt+vinggar solution
- put 50ml of molL+ NaOH into a beaker
- heat bunsen burner until nearly boiling - stair as heating then take off heat
- add a spatula of zinc powder
- heat lightly for 3 min, with a coin in - stir as heating
- take the coin out with tongs
- rinse coin under water to remove chunks of zinc.
- wave coin in the blue flame using tongs.

Equation:

zinc + sodium hydroxide = zinc hydroxide

Observation: the coin changed to a silver colour when it was put into the beaker that contained sodium hydroxide and zinc powder. after they were rinsed in water the were put under the flame as they turned into a gold colour.

Science: Periodic table Task
