167 Task 3 

Personal Health And Safety pg 5 

As you can see in this image I am wearing a clean apron that is ready to be used for the cooking activities ahead of us, which means no previous food or bacteria is on it and able to contaminate the food. 
As you can see Lavisha's hair is pulled back an out of her face which means lo lose strands of hair will be falling into the food and contaminating it.
This image shows clean hands with no nail polish or jewellery on them which means no chips of nail polish or dirt from jewellery is able to contaminate the food.
This image shows leather shoes that cover the toes so that if hot water, oil or knives are dropped on your feet they will be protected and the person is less likely to be injured if any of those things happened.










Here I am washing my hands after carrying out and unavoidable task the may cause contamination such as touching and cutting raw meat like chicken and red meat, to make sure no cross contamination has occurred and is less likely to infect anyone.









When cooking it is important to avoid personal habits you may have such as scratching your face, touching you hair, mouth and nose area and also avoid spitting. As if you were to do these habits while cooking you would be contaminating what food you are making.

Having good work habits is important, such as using a clean utensil to taste food or sauces, using disposable gloves if you have any open wounds that need covering and also using tongs to dish and collect food.

Covering any skin conditions, cuts or open wounds that may cause infection is important due to the high contamination risk's that come along with them. Cover a cut or open wound with a plaster and then place disposable gloves over top.

Workspace Hygiene, pg 7

It is important to wipe down your workspace with a manufactures antibacterial spray made for a kitchen before and after cooking to get rid of any bacteria or food particles that were there before you started cooking and also after you have finished cooking. It's also very important to keep your space clean and sanitized when you are cooking to help stop the spreading of bacteria.

When cooking and storing food it is important that they are handled in the appropriate conditions. When storing ingredients in a pantry it is important you put the older stuff at the front and newer ingredients at the back if they are canned food or can be frozen. When preparing food it's important to prepare different ingredients on their correct boards to avoid cross-contamination. When preparing chicken when you don't need it straight away store it in the fridge until you need it. When storing ingredients it's important to store them correctly in the right place. If they need to be chilled place them in the fridge or freezer, otherwise store them in the pantry.

Removing rubbish from your cooking area and storing it in covered containers, in designates area prevents the infestations of pests.

Temperatures, pg 9

Chicken should be cooked to the correct temperature of 75 degrees, to prevent any illness like salmonella, which makes you very sick. When reheating food it should be piping hot and at 80 degrees, that way you know its reheated all the way through.

Handling Of Knives 

Safety 

When carrying a knife you must hold it from the handle so the blade is facing the floor. This is the safest way to hold it if any accidents were to occur. As shown in this image.

When setting up your knife station for your practical it is important that you have a wet cloth under your board to stop it from moving around. You must use the correct board and matching knife for the correct task to avoid cross-contamination also.

 It is also very important that you are using the correct knives for the appropriate tasks you're doing.
Here is a video on knife safety by Jamie Oliver
https://www.youtube.com/watch?v=yJ44SxiemMs

This image is of a green cutting board with a wet cloth underneath to prevent slippage while cutting on the board.


Maintenance 

It is important to keep knife maintenance up to standard by sharpening your knives regularly either by using a steel or a wet stone block and are making sure to hold your knife on a 45-degree angle to get the whole blade sharpened.

When using a set stone block it is important to hold your knife on a 45-degree angle and start at either the right or left top corner and end on the opposite side of the one you started at. Do this 5 to 10 time on the darker side first then repeat on the other side.

Keeping knives sharp is important as using a blunt knife is dangerous and makes things harder to cut and gives you more risk of cutting yourself.




Storage 


When storing knives it is important to keep them away where little hands can reach them and in a safe place that isn't a hazard for people using them.



Our two practices for knife handling were fruit salad and a chicken stir-fry. 




__________________________________________________________________________________________

Boiling

Prepare to boil the food items
When boiling it is important to inspect the quality of the ingredients by checking the appearance, smell of the food and the date of expiry. It is also important to prepare food items using procedures that meet the cooking requirements. You do this by checking the skin of ingredients, you check the freshness of eggs by putting them in a bowl of water if they sink they're fresh if the float they are off as there is a big air bubble on the inside.

Boil food items 
When it comes to boiling the food items is important you check the degree of cooking which is the time. When boiling eggs you should cook them for 5 to 10 minutes and when cooking vegetables it is important not to over boil them as they should be soft but not mushy. The temperature for boiling food should be 100 degrees, gentle boiling makes it easier to break down the tough structure which makes it easier to work with. Placing food into a cool liquid and bring it to a boil then reducing it to a simmer is a good way to cook starchy foods like potatoes which take longer to cook. When simmering it is important to bring down the temperature of the water down to 95-98 degrees as if the water continues to boil there is a risk the food will break.

 

Present food items
When you present the food it is important that the dishes are plated the same and like alike, it's important that the portioning is suitable for the person eating it and the proportions are the same. With sauces, they should either be mixed in with the food or in a small bowl on the side. For proportions, each person should have 2 medium eggs, 110g per person for root vegetables and 125grams of tuber vegetables and 100 grams of green vegetables per person.












__________________________________________________________________________________________


Grilling 


In this weeks practical we used the under and between type of grilling for our meats. We grilled the bacon under the oven grill and grilled the steak between the sandwich press.

The types of checks we made were looking at the colour and smell of the bacon and steak to make sure it was fresh.  For the vegetables, we looked at the appearance and colour of them and the smell.


The degree of cooking the bacon was 5 minutes and the degree of the steak was a few minutes. The appearance of the steak once it was cooked had frill lines and the bacon was crispy. The vegetables had grill lines too.



We each had three pancakes with two strips of bacon and had a banana each with some syrup. We used 1 banana each because it's important to get your 5+ a day. We had 3 small pancakes because it made around about 2 servings of carbs, which will help keep you full.





 The steak sandwich was filled with 100 grams of steak each with onion capsicum and a teaspoon of aioli.





For the second practical we did a full breakfast which included a grilled tomato. Which we used the grill plate for which left lines on the cut side of it. The other dish we made was lamb kebabs with vegetables, we also used the grill plate which left lines on side of the meat and vegetables.

Image result for grilled tomatoThe grilled tomatoes looked something like this because of the grill plate lines they had more and were smaller.

When choosing our tomatoes we made sure their skin wasn't soft or wrinkly had a good smell and colour to them, as we know that means their freash.

It was the same with the meat we made sure the smell wasn't bad and it had a good colour to it.

The temperature for cooking both was around 6 on the cooktop so they didn't burn but it didn't take to long we cooked the tomato for around 5 minutes and the lamb for about 4 depending on how many times we had to rotate them.

Steaming 

Dumplings 

When checking our cabbage for our dumplings we had to check for the quality of the food in its appearance we had to make sure it was fresh and, not old so the cabbage would be hard, not soft. You also need to wash it and check for dirt and bugs. when checking our meat for the dumplings it was important to look at the texture, smell and colour. The pork and chicken mince had all the right indicators.


 

We used a light method of steaming by frying the dumpling on one side to give them some colour then we added a cup of water and placed the lid on the pan to let them steam for 4-5 minutes. 
   We served the dumpling with a small saucer of say sauce and had around about 6 dumplings. 

Vegetable Soup 

For our vegetable soup, we made sure the carrots, kumara, pumpkin onion, and potatoes we made sure that they had no blemishes, smelt and looked good and when peeled they were nice on the inside. We then cut them cut the head and tails of the kumara and cut them into squares.

Link to the vegetable soup we made. For our soup, we made the soup in a pressure cooker which is high pressure steaming.

Each person had roughly a cup of vegetable soup and  1 slice of garlic bread. To prepare the vegetables we cut and washed them then put them in the pressure cooker for 15 minutes. Once it had finished cooking it was mushy but once blended together the texture was smooth. We were told the soup was good and the garlic bread was great.

Fish and steamed vegetables 
When it came to the fish we evened it out into even portions of 200grams, we looked for quality indicators which included smell, texture and appearance. We steamed the fish in a steaming basket for around 8 minutes till it was white and flakey.

The vegetables we used were carrots and beans. We started by washing them and then top and tailing the beans, we then checked the quality of the beans and made sure the beans weren't stringy. We cut the carrots into batons so they would cook evenly alongside the beans. We steamed the fish in parcels and tied the vegetables together with string. This was low pressure steaming.

 

Prawn and couscous salad

We steamed the prawns using low pressure steaming.
Key indicators that the prawns are fresh is that they smelled slightly, the eyes were not shrunken and it had a nice glossy shell, the prawns we used all had these. The couscous was fine to eat as it was in its expiry date. 
To plate, we served around about 1 cup of couscous mixed with rocket and capsicum and had 4 prawns on top. 
For the preparing of the prawns we removed its head, tail, shell, legs and its dirt track. Then rinsed them with water. 
We steamed the prawns in the steaming basket for around 5 minutes. To cook the couscous we lightly toasted it, then boiled it with water and chicken stock until the liquid was all evaporated. We then lightly toasted some pine nuts.
For serving we plated by adding the couscous, rocket, capsicum and pine nuts. We then plated the 4 prawns on top and drizzled over the sauce. 

  


__________________________________________________________________________________________

  Vegetable and fruit cuts 

The quality of the vegetables we used was fresh and made sure they had no blemishes, such as bruises or rooten areas. By smelling the vegetables we could tell if they were fresh or not as if they were bad they would have a funky smell. By looking at the outside skins of the fruit and vegetable you could tell by the texture if they were good or not. 






    



When cutting the vegetables for the fruit kebab we made sure to cut them in even chunks for presentation. By using different fruits it provides different textures. 

When cutting and preparing fruit it is important to wash and peel the fruit to get rid of any dirt or bacteria. 

For our vegetable baskets, we cut the vegetables evenly throughout the different types of vegetables so they cooked evenly and were bright in colour.  

By cooking starchy vegetables first its gives them along enough time to cook before we add the others as they take longer to cook.


When presenting our flans we cut the fruit in the pattern we were aiming to create. If wanting to add icing sugar we could have sprinkled it on with a sift. We drizzled the chocolate sauce over evenly as well.

Formal Writing

Are Pitt Bulls a vicious breed?

Pit Bulls are a breed of dog that was originally bred to bite and attack other large animals, but does that really make them vicious dogs? The history, look and personality traits of Pit Bulls form people's opinion on them, but also how the dog was brought up and what experiences people have had with them.
Pit Bulls have a bad reputation because of what they were originally bred for back in the early 1800s. However the dog turns out is entirely up to the owner and how they have raised the dog. In some cases, Pit Bulls are bought to make their owner seem tougher. Some owners train their dogs to be vicious, which is entirely the wrong reason to buy the Pit Bull breed and doesn't help with the judgment the dogs already have against them. Pit Bulls were bred to have a lot of aggression, a high pain tolerance and a willingness to fight to the death, however they were not trained to attack humans. It is understandable why people are so quick to assume that every Pit Bull they come across is vicious because of their history and the bad reputation they have.
People judge the dog by its look. When we see a Pit Bull with a muzzle we are automatically wired to think that the dog must be vicious because of how the breed is portrayed in the media. In the UK the Dangerous Dog Act (DDA) states that anyone who owns a “ type of dog known as a Pit Bull Terrier” must have it neutered, keep it muzzled and on a leash in public. These dogs should not be made to wear muzzles if they aren't vicious dogs. If a non-vicious Pit Bull Terrier has been made to wear a muzzle, they are automatically portrayed as dangerous although they may not be, which is unfair to the owners and the dogs.
The personality traits of a Pit Bull are affectionate, intelligent, obedient, loyal, courageous, friendly, strong-willed, clownish and stubborn. With personality traits like these, it makes us wonder why Pit Bulls have the highest dog attack statistics in America. Statistics like these are understandable if the dog ends up in the wrong hands but if the Pit Bull is in a warm loving home they are known to be some of the sweetest dogs. The problem with the statistics lies with the owners who have trained the dogs and not the actual dog breed itself.

In conclusion the history, look and personality traits of a Pit Bull form people's opinion on the breed. The statement that Pit Bulls are vicious dogs, it is incorrect and it comes back on how the dog was raised and how the media only portrays their bad side.

Compare and contrast Dr Jekyll and Mr Hyde with The Invisible Man



The Invisible man vs Dr Jekyll and Mr Hyde 

These two books have very similar themes 


The Invisible man is about a scientist named Griffin Who researches optics and discovers a way to make himself Invisible but unfortunately becoming invisible actually destroys his life, turning him against mankind, and turns evil.

Dr Jekyll and Mr Hyde id about a doctor who discovers a way to split his personality into two distinct human beings: the rational, intellectual side and the physical, desire- driven side. Hyde isn't considered evil but did evil things.

Science

Experiment 1     Investigating the effects of temperature on reaction rates

Aim:
I want to investigate hoe temperature effects the reaction rate.

Equipment:
  • Conical Flask
  • Beaker
  • Measuring Cylinder
  • Stopwatch
  • Black cross on paper 
  • Water Bath 
  • Thermometer
  • 0.1mol/L sodium thiosulfate 
  • 1.0mol/L hydrochloric acid ( HCL ) 
Method: 
  1. Put X on paper on the bench mat, and put the conical flask on top of paper 
  2. Measure 50 ml of sodium thiosulfate solution and put it into beaker. 
  3. Record the temperature of the sodium thiosulfate.
  4. Measure 5 ml of HCL and pour this into the conical flask. 
  5. Pour the thiosulfate into the conical flask start the stopwatch and swirl the flask, time how long it takes for the cross to disappear when viewed from above i.e look down from the mouth of the  conical flask.
  6. Wash flask thoroughly.
  7. Repeat the experiment using a water bath to heat the sodium thiosulfate to 30 degrees 40 degrees and 50 degrees keep the volume of acid the same each time. 
Results 
  • room temp 28 seconds 
  • 30 degrees 50 seconds 
  • 40 degrees 19 seconds 
  • 50 degrees 18 seconds 


Conclusion: A chemical reaction is when two reactants collide, they have to collide with enough force to and the correct orientation. As we made the temperature hotter it gave the reactants more kinetic energy so they moved faster. The faster the reactants move the higher chance of a successful reaction to occur in a lesser time. 



Experiment 2  Investigating the effect of concentration on reaction rate

Aim: I want to investigate hoe concentration effects the reaction rate.

Equipment: 

  • A conical flask 
  • measuring cylinder 
  • stopwatch
  • black cross on paper 
  • 0.2mol/l sodium thiosulfate 
  • 1.0mol/l of hydrochloric acid 
Method: Put the piece of paper with the X on the bench and put the conical flask on it.

  1. Measure 10mL of Sodium Thiosulfate and put it into the conical flask.
  2. Measure 40mL of Water and put it into the conical flask. Swirl to mix.
  3. Measure 5mL of HCl.
  4. Pour the Sodium Thiosulfate into the conical flask, start the timer and swirl the flask.
  5. Stop timing when the you can't see the cross on the paper.
  6. Wash out the flask thoroughly.
  7. Repeat experiment 20mL of Sodium Thiosulfate and 30mL of Water.
  8. Repeat experiment 30mL of Sodium Thiosulfate and 20mL of Water.
  9. Repeat experiment 40mL of Sodium Thiosulfate and 10mL of Water.
  10. Repeat experiment 50mL of Sodium Thiosulfate and no Water.
Results 

10ml of thiosulfate and 40ml of water took 3:22 seconds to react
20ml of thiosulfate and 30ml of water took 1:58 seconds to react
30ml of thiosulfate and 20ml of water took 0:57 seconds to react
40ml of thiosulfate and 10ml of water took 0:52 seconds to react

Conclusion: In conclusion the more thiosulfate you add and less water it is quicker to react and the more water and less thiosulfate you add it takes longer to react.


Experiment 3: Observing the effect of surface area on reaction rate

Aim: To make the simple observations during a reaction between calcium carbonate (CaCO3) chips powder with hydrochloric acid (HCL).

Equipment: 

  • Boiling tube 
  • Calcium Carbonate chips 
  • Calcium Carbonate powder
  • Hydrochloric Acid
  • Measuring cylinder
  • Spatula 
Method: 

  1. Measure 2mL of hydrochloric acid and pour this int your boiling tube.
  2. Holding your boiling tube over a sink or heatproof mat, add a pea-sized amount of Calcium Carbonate powder  to your boiling tube. Record your observation. 
  3. Repeat the experiment but this time use a chip of calcium carbonate that is roughly the same size as the spatula of powder you used previously. Record your observation. 
Observation of Calcium Carbonate powder: When the powder reacted with the acid it fizzed up and small bubbles appeared at the top.  
Observation of Calcium Carbonate chip: When the chip hit the acid tiny bubbles came up from the bottom. 

Conclusion: 



Experiment 4  Observing the effect of a catalyst on a chemical reaction

Aim: To observe the effects of a copper catalyst on he reaction between zinc and sulfuric acid.

Equipment: 

  • Three test tubes
  • test tube rack 
  • 10ml measuring cylinder 
  • dropping pipette 
  • granulated zinc
  • copper turnings or powder 
  • dilute sulfuric acid 

Method 

  1. Add roughly the same mass of zinc in test tubes 1 and 3 
  2. Add roughly the same mass of copper to test tube 2 and 3 
  3. Add 5 ml of the acid to test tube 1 note the rate and production of gas bubbles
  4. Add 5 ml of acid to the test tube 2 note the rate and production of gas bubbles 
  5. Add 5 ml of the acid to test tube 3 not the rate of production of gas bubbles 

Test tube 1: When both products reacted it bubbled and went cloudy. 
Test tube 2: When both products reacted s few bubbles a pared and the powder went to the top and then the powder turned clear. 
Test tube 3: The products bubbled a lot and it separated. 

Catalyst: It speeds up a chemical reaction

Purpose of test tube 2: It was to show what would happen with only copper and the acid, it didn't react.
