Yee yee we back in Business Babayyyyyyyy

3 things that went well
Personally, I think that our business and sales went very well. I think that our product was very popular in the market and it was enjoyed by the people that purchased them. I think that once we got into the groove of things, our packaging and presentation looked better each time. We did sell out of everything quite quickly which was quite amazing to me because I didn’t expect to sell out that quickly. We made $123.5c which was much more than we thought we would make because we made more burritos than we thought we would. I do think that I personally did very well on the packaging side of it because when we were serving to the customers, they did enjoy the look of the packaging. 

3 things that didn’t go so well
The day before market day was very chaotic. We only bought our supply the day before the sale and we also bought things that we didn’t really need, such as forks. Maybe instead of not purchasing forks, just to buy one packet. I also think we should have taken it slower with preparing the burritos. I did enjoy preparing the burritos and am glad that I packaged it because I made it look presentable. I do think that we should have worn gloves because it might have turned the customers off purchasing our burritos. One part of the feedback from a customer was to wear gloves so that is something that didn't go very well. There's always something that we can improve.  

3 things I would change 
I do think that we should have worn gloves while preparing the burritos for the customers. I do think that the customers didn’t like the fact that we weren’t wearing gloves if they even noticed. I do think that I should have been preparing the burritos from the start. I think that I should have also made more posters earlier and then put them all around the school because it would have drawn people to our stall. 

Extracting DNA *cough cough Organs* Genetics 🔬 🧪🧬

I lied, we didn't extract any organs, cause I'm pretty sure that's illegal, and I don't think I need anything on my permanent record. 
K, so Mr Heath is going to extract all our DNA and all our organs and sell them on the Black Market. Just kidding guys, I do Brazillian Jiujitsu now so I can kick his butt and he's too scared to mess with me anyways. Notice how I say the word butt but I really mean a**. 

ANYWAYS, For our Genetics topic in Science, we conducted an experiment, extracting DNA from a Kiwifruit. Turns out you need quite a lot of equipment, so keep that in mind if you are planning to conduct this experiment yourself. You also need Ethanol, now I'm not sure if you can purchase it anywhere, so be mindful of that if you wish to conduct this experiment. Ethanol is stronger than stomach acid, let that sink in for a minute. 

Just thought I would give you a brief lesson on extraction. Nowadays, when people hear the word "extraction", a lot of them think of pimple or earwax extractions, and maybe even organ extractions. In a scientifical context, extraction is a way of separating a substance desired when it is mixed with other substances. So in normal words, it's taking out a substance that has been mixed with other things. So in this case, we were extracting DNA from a Kiwifruit so we were taking out the DNA from it, or separating it.

Equipment for the extraction 
Kiwifruit (don't eat it)
Scalpel (this is sharp, please don't cut yourself cause I'm not being responsible for you cutting yourself, I don't want to be sued)
Scientific spatula (not the type you cook with, wouldn't want to die because of the chemicals in the laboratory)
Ziploc Bag (like the bag you used to put all your snacks in during primary school, you could still do it now, I don't know your life)
25mls of water (have you drunk enough water today?)
A pinch of salt (if you want to be all food scientific, a pinch of salt can be measured at the end of a knife)
Small cloth to wipe all your tears away (just kidding I'm sorry)
Funnel (the triangle looking thingy)
Beaker (This is the piece of equipment that looks like a cup)
Test tube (where the extraction occurs)
A squirt of Dishwashing liquid (I don't know what measurement a "squirt" is equivalent to, but just a tiny bit)
10mls of Ethanol (Don't drink the Ethanol you idiot, you don't want to die of poisoning)

Method of the extraction (read carefully) 
1. CAREFULLY using the scalpel, slice the kiwifruit in half. Be careful not to cut your fingers off, cause you need fingers, and you don't want to lose your precious phalanges (look at me using the scientific term for finger bones, you should be proud)
2. CAREFULLY using the spatula, scoop out the goopy remains and insides or flesh of the kiwifruit and place it in the Ziploc bag. (NO YOU CANNOT EAT THE KIWIFRUIT, IT IS IN A LAB. LAB=CHEMICALS, CHEMICALS=POTENTIAL HARM TO HEALTH, HARM TO HEALTH=SICKNESS, SICKNESS=POSSIBLE DEATH, soz that's a bit dramatic but you can't be too careful.)
3. Add 25mls of water and the pinch of salt to the ziplock bag
4. Close the bag and use all your anger to mush the kiwifruit into a soup-like paste. Channel your inner boxer to mush the heck out of that kiwifruit.
5. Place the cloth on top of the funnel and the funnel over the beaker. Pour the soupy kiwifruit mixture liquid into the funnel/cloth. (DON'T EAT IT)
6. Pour the liquid from the beaker into a test tube
7. Add your squirt of dishwashing liquid to the liquid and swirl it around in the test tube.
8. Allow to sit for 5 minutes
9. Tilt the test tube on a 45-degree angle and slowly pour the 10ml of Ethanol into the mixture. (DON'T DRINK IT)
10. Allow the mixture to sit.

Results of our experiment
So I do believe that our experiment was successful. After we completed all of the steps and allowed it to settle for a few minutes, the mixture had white strands that rose to the top, which was the DNA. The mixture separated into three sections, the top section looked quite cloudy and it formed together quite nicely. The middle layer separated the foam and was clearish and looked like water and the final layer at the bottom looked like kiwifruit juice and was green (just like Kermit the frog). You may not be able to really see it in the photo and it's quite hard to see, so you're just going to have to trust me that, these were the results.  The vertical photo was after the dishwashing liquid step. The photo beneath this text was after all of the steps.











Discussion

Yay, now you get to read me rambling on about extraction, wooo, lucky you.
So the steps we took allowed us to separate the DNA from the rest of the contents in the Kiwifruit, so in the end, we got to see all the DNA in half a kiwifruit which was cool. In the end, Mr Heath did give us permission to play with the remaining DNA in the test tube, so we picked it up and felt the texture which was quite jelly-like. The water that we added aided in the breaking of the kiwifruit and but didn't really provide many other uses. The salt was used to aid in the clumping process of the DNA and you can see that in the white foam at the top of the mixture. Salt is used in many different chemistry experiments in this way. The foaming detergent made the DNA more prominent than just the white foam and we could actually see at least some of the DNA strands, and they stood out so much due to this detergent. As the detergent is bubbly and easy to study, it really did help this experiment. The ethanol was what provided the strands of DNA and the foam to rise to the top. Ethanol has a different density to the water, which is what caused it to rise to the top, and brought the kiwifruit DNA strands with it.

Conclusion
So what have we learned reading this post? Well obviously, DON'T EAT FOOD IN THE LAB, seriously, it can be very dangerous and we don't want any harm to anyone. Fun fact, Ethanol is stronger than stomach acid so it could cause death, be very careful. I am very glad that we were able to extract all of the DNA from half of a Kiwifruit, our experiment was very successful. I honestly, before this, didn't know the full scientific definition of what extraction was so that was good to learn. We have learned that with the extraction of DNA, the process is quite simple and that we can separate DNA from other contents within fruits and other things. I do think that this was quite interesting. I still think I prefer Chemistry over Biology, but it's starting to grow on me and I've enjoyed this topic.

Composition stoof

What is Composition?
Composition in the musical context is when someone composes a piece of music or creates something that relates to music.

What style of composition have you chosen? 
I have chosen to compose a piece of music for a horror film scene because I think I have skills in this area.

What ideas do you have so far and what do you need to work on?
So far I have composed my piece and it is starting to come together. I now have to choose a scene to use.

Explosion thingies, AKA Volcanoes

How do Volcanoes form?

Volcanoes occur because of the movement of the tectonic plates. The movement of a plate sinking beneath another plate into the mantle makes it become very hot and it then melts due to the friction. This is called Magma, and as it rises through the cracks of the earth surface, causing pressure buildup and it eventually is released. Once this pressure is released, the magma flows to the surface causing what is known to be called a volcanic eruption. Once the magma has reached the surface, it erupts to form lava flows and ash deposits, once that has cooled, it forms a new crust. After years and years of buildup of this lava creates the Volcano shape that most people are familiar with. 

The Diamond Head Volcano in Hawaii

The Diamond Head Volcano is a volcanic tuff cone on the Hawaiian island of O'ahu and is known to most Hawaiians as Le'ahi. This volcano is widely known for its beautiful views of O'ahu as well as the humungous crater at the top. Lying at the southern edge of Waikiki, Le'ahi is an extinct volcanic crater and tuff cone. It was the site of a Luakini Heiau, which is a historical structure dedicated to the war god and was used for human sacrifice as well as devotion to the god. The name Le'ahi was originally given to the volcano by the Ancient Hawaiians. It is most likely that lae "brow ridge, promontory" and ahi "tuna" because the shape of the ridgeline of the crater as seen from Waikiki resembles the shape of a tuna's dorsal fin. But it can also mean "wreath of fire" and refer to the navigational fires lit on the summit to assist canoes travelling offshore. It was known as the Diamond Head in 1825 when the British sailors and settlers mistook volcanic crystals for diamonds. The volcano is estimated to be 150,000 years old and extinct for 150,000 years. The Diamond Head crater was formed from many cones and vents. It is responsible for a series of volcanic eruptions called Honolulu Volcanic Series. The eruptions caused several popular landmarks in Hawaii to emerge. The eruption that created the Diamond Head lasted for only a few days. 

Many people visit the Diamond Head Crater every year. It is quite a famous tourist attraction. Visitors to Waikiki often hike to the Diamond Head Monument. It takes around 2 hours to reach the observation deck, but if you are quite an efficient, fast walker, it could take less than an hour. There are many stairs on the way up to the monument and a small tunnel that you have to pass through. Once you reach the observation deck, you will be able to observe the scenery of Waikiki. 

Hawaiian legends say that the volcanic cone was one of the places where Pele, the volcano goddess, and her younger sister, Hiiaka, lived as they searched Hawaii for a permanent home. 

Our Volcanic Eruption 

After researching volcanoes, we were given the task to create a model of one of our group members volcanoes. Jessica's volcano was the volcano we used. Mount Vesuvius. Using paper mache, we created the volcanic structure of the volcano and then painted it. We erupted the volcano and it went quite well.

4 spatulas of Potassium Iodide in 20mls of water 
 20mls of 35% hydrogen Peroxide 
Dishwashing liquid 
Red Food colouring 
H202--------> H20 + O2

First, we mixed the Potassium Iodide and the water together in the small beaker until it was clear like regular water, While Jess was doing this, Molly and I mixed the rest of the ingredients into our volcano. To create the final lava flow, we added the iodide mixture into the bottle and watched how it erupted. This experiment worked because Hydrogen Peroxide is water and oxygen and slowly separates. The Potassium iodide was asses to the hydrogen peroxide to speed up the eruption process. The glitter we added also made it super sparkly and I love it.
