Explain in detail what the drug is.
Heroin is a very addictive Class A opioid drug. Heroin is made from the resin of poppy plants. Milky, sap-like opium is first removed from the pod of the
poppy flower. This opium is refined to make morphine, then further refined into different forms of Heroin.

Explain what the drug looks like (provide pictures)
Heroin can look different depending on what additives have been added to the substance to dilute it. But the most common look the heroin has is a fine white powder with specs of brown or black if it is in powder form, or a dark brown liquid if it has been dissolved in water or other liquids.

Liquid Heroin                                  Brown powder Heroin             White powder Heroin

How is it used?
Heroin is most commonly consumed by injection into the forearm using a syringe. However, it can also be taken by snorting the powder through your nose.

What influences adolescents/teenagers to use drugs and why? (cover P.I.S influences) Some personal influences that teenagers experiance are: 1) They are just simply curious to know how it feels 2) They need to not to feel a.k.a they are overwhelmed with stress and/or emotional struggles and they dont know hpw to cope with it. Some interpersonal influences are: 1) Peer-pressure, friends are pressuring you into taking it. 2) Most of your family does it so it seems “normal” for you to do it aswell. Some socialtal influences are: 1) Community/poverty factors, lack of oppertunities or unsafe enviorments can push make people ‘need’ drugs to cope.Explain the positives and negatives associated with the use of this drug? To answer this question, you need to include information on: 2) Media, different types of media ads, songs or movies can normalise it or make it seem better or glamarise it.

Explain the Short term and Long term effects on wellbeing (cover P.I.S effects)                

Some short term effects are: Drugs can create mood swings,clouded brain making you more prone to doing risky things that will injure you. Lack of sleep and hightented anxiety are also causes of heroin.

Some long term effects are: Damaged organs which overall just decreasses your life excpectancy. Another long term effect is job loss which results in loss of incoe which could result in you loosing your home.

Impacts on Wellbeing
Some impacts that heroin could provide a person is that it could calm them down or dull their senses causing them to forget something emotionaly pain full to them and this could be seen as positive for some poeple and negitiv to others. This would impact someones emotional wellbeing because it could lead to addiction because they just want to use it to escape thier problems when it is just better to embrace and talk about them. It would also impact someones physical wellbeing because it would cloud their brains makeing them more likey to do something hurts them because the pain scale part of the brain cant function properly. Social wellbeing would also be impacted because if someone in your life feels strongly against it they would ditch you and not speak to you anymore.

What are the laws or restrictions of your chosen drug and what are the penalties?
The laws around heroin in New Zealand are that you can get a $1000 fine, 6 months inprizenment or if you are caught trying to sell it could be both. This is because heroin is a class A drug.

Explain what strategies you would suggest to a person between the ages of 13-18 about things that they could do to keep themselves safe around your chosen drug?
A way a teenager can stay safe with heroin is to learn what it actually does to your body/mind and all the long term effects it has on you.
You could also surround yourself with the right people who will guide you in the right direction and not to do drugs.
Talking to trusted adults about it can also help you avoid doing drugs.
You can also call or text the 24/7 drug help lines.

Decision Making

Senario Options Consequences Feelings Best option
You decline respectfully and go to class clean You feel sad you dont get to get high but you are learning ready Sad, but grateful
It is the start of interval; you receive a text. The text is from your friend. Your friend tells you to meet them at the back of the field to use heroin

 with them. 

 You go and go to class high You are not learning ready and go to class high High and cant feel anything The best option is option 1 because no one gets hurt, and you don’t go to class high, so you can get work done.
Get into a fight over it You get into a fight, and you are angry in class and can’t focus angry

Experiments

1) What were the different experiments you completed?
We have completed four different experiments so far this term. We have completed the hydrogen pop test, lime water test and the burning magnesium, all of which had a different reaction. Plus, a teacher demonstration of sodium in water.

2) What observations did you make in each experiment?                                                                                                                                                                                                                – Hydrogen pop. For this test, we placed magnesium into a test tube filled with acid and covered the top with our thumb. The acid then reacted with the metal, which started fizzing as the hydrogen gas rose.  The hydrogen suctioned my thumb to the test tube. As the pressure got to a certain point, we lit a wooden stick on fire and placed it at the top of the tube. Magnesium + hydrochloric acid –> magnesium salt + hydrogen                                                                                                                                                                                                                    Mg + HCl –> MgCl + H

– Lime water test. With this reaction, we placed calcium carbonate, aka marble chips, into hydrochloric acid. We then placed a delivery tube with a bung at the end to transport the hydrogen gas to another test tube with lime water in it. The acid was very reactive with the calcium carbonate; however, our plug could not be sealed properly, so all our carbon dioxide escaped and could not be transferred to the test tube with the lime water.                                                                                                                                                                                    Calcium carbonate + hydrochloric acid –> calcium chloride + water + carbon dioxide                                                                                                                                                                            CaCo3 + HCl –> CaCl+ H2O + Co2

– Magnesium burning. This experiment is when the magnesium heats up, then reacts with oxygen, making a bright white light before turning into a metal oxide. Taking the magnesium out of the frame made the flame brighter, making the magnesium react with heat and oxygen with a bright white light. (If you look at the bright white light, you will have spots in your vision for about 1 hour.)                                                                                                                                                                                                                                          Magnesium + Heat + Oxygen –> Magnesium oxide                                                                                                                                                                                                                                          Mg + O –> MgO

Water bottle rockets – Science

Our Times: 1.87   –   2.34  –  2.09  –  2.47  –  1.80  –  2.10

Average time: 2.11

Distance: 29.10 meters

Speed: 13.79 meters per second

 

Aim: The purpose of the bottle rocket experiment was to observe the forces acting on an object and how they affected its flight path and acceleration. As well as speed.

Equipment: For this experiment, we didn’t need a lot of materials, as there were only 4 key materials needed for this experiment. However, that’s not including all the materials we wanted to use to make our rocket look its best and enhance its aerodynamics. So overall, we ended up using:                                                                                                                                                                                                  –  Red paper                                                                                                                                                                                                                                                                                                                                                  –  Yellow paper                                                                                                                                                                                                                                                                                                                                            –  White paper                                                                                                                                                                                                                                                                                                                                              –  Card board                                                                                                                                                                                                                                                                                                                                               –  Coloured pens/pencils                                                                                                                                                                                                                                                                                                                          –  Scissors

And for the actual launch process we used:                                                                                                                                                                                                                                                                                                –  A 30 meter measuring tape                                                                                                                                                                                                                                                                                                                  –  Stop watches                                                                                                                                                                                                                                                                                                                                            –  Water                                                                                                                                                                                                                                                                                                                                                        –  Launch Station                                                                                                                                                                                                                                                                                                                                        –  Rubber cork                                                                                                                                                                                                                                                                                                                                              –  Air pump

Method: The method for this experiment was quite straightforward forward build the rocket, launch the rocket. But here’s a more detailed explanation.                                                                                 1) First of all, we grabbed a bottle (our one was an old Pepsi bottle), then we planned the design around the aerodynamics and looks. We ended up choosing a design based on Lightning McQueen. To do this, we taped red paper around the bottle and added extras to make it look like him.

2) Next, we filled the bottle 1/3 of the way up with water before taking it outside to the launch station, ready to be launched.

3) To launch, we plugged the bottle with the rubber cork and attached the air pump to it before placing it on the launch station.

4) When we pumped the pump to make the air pressure release the plug 9 people had stopwatches ready to time the bottle to get a more accurate result.

Discussion:                                                                                                                                                                                                                                                                                                                          Forces: There were four different types of forces acting on our rocket during its flight they were lift, gravitational pull, push and drag.  These forces would have been balanced at the peak of the rocket’s flight before gravity took over, making the forces unbalanced. These forces are slightly different for each bottle rocket depending on its shape and weight; They also change throughout the flight. For example, our rocket went in a straight line quite far, while someone else’s didn’t go very far and spiralled in the air. This is because their forces were unbalanced. This can all be defined under net force, which is the total amount of force acting on an object in a direction.

The change of forces: Forces change a lot during the flight of the rockets.                                                                                                                                                                                                                            First, the thrust force is the strongest because it’s just been launched, and the lift will also be quite strong as it’s travelling up very fast.                                                                                                                  Next, when the rocket reaches its peak height, the weight or gravitational pull is at its strongest, pulling it towards the ground. The friction is also very strong now as the rocket is slowing down.        Finally, when the rocket lands or crash-lands in some cases, all the forces are equal as it’s not moving anymore.

Why were all the results different? All the results were different because of the way the rockets were designed.  As all the aero-dynamics were different, the amount of water that was used to power the rocket could have also played a part in how far it went, as a less filled rocket wouldn’t have as much thrust as one with slightly more water.

Net forces: Net force is the amount of force acting upon an object in a direction. E.g. the net force for our rocket would be the upward thrust created from the water leaving the bottle creates an upwards net force, causing the rocket to accelerate upward.

Physics Concepts: Newton’s second law of motion can be linked to this experiment as it states ” Force = mass times acceleration / F=ma”. We have been using this law of motion to help us calculate speed, mass and acceleration of the rocket and other objects this term.                                                                                                                                                                                                                    Newtons first law of motion can also be linked to this experiment as it states “An object at rest stays at rest, and an object in motion stays in motion with the same speed and direction unless acted upon by an unbalanced force.” This can be seen in this experiment as the rocket stays at rest until the water is pressurized enough to launch it into the air. The water in this case is the unbalanced force.

Conclusion:                                                                                                                                                                                                                                                                                                                                            At the end of every experiment, you can improve the prototype or the experiment in general. These improvements are important because everything can be made better and changed to get better results. And if we never improved anything, we would stay at the same place, and nothing would be modernised, and everything would be outdated and useless. But for experiments, if we never added improvements, we wouldn’t learn.

Symbolism–Catherine called Birdy movie

In the movie Catherine called Birdie, when Catherine releases the doves at the end, this symbolises Catherine being at peace with herself and being set free. This is because during the movie Catherine is compared to a bird, showing that her peace is trapped in a cage like a bird. This means that just like the doves in the cage, Catherine is trapped by her life because of her father and the restrictions she has as a female. Overall, the freeing of the doves at the end of the movie symbolizes that Catherine is now free, and the type of bird used (the dove) also sybolizes that her inner peace is also no longer trapped.

Paper Boat–Science

Something that went well in this boat design is the way the base is shaped to displace a large amount of water to help with the buoyancy. Because of this, our boat was able to hold 14 weights before it sank.

Buoyancy is when water is pushed out of the way by an object, and when it rushes to fill the space again, the water pushes against the object, keeping it afloat. Buoyancy is going to be greater when the object is filled with more air because water is more dense than air. Even if the object is made of steel and aluminium, if it has the correct amount of air in it, it will float and become buoyant.

Our boat was very buoyant due to the large amount of water its hull displaced.

 

 

CAA Reflection

I believe that I was half prepared. This is because I think I was prepared educationally. However, I believe that I was not mentally and I was very stressed going into the exam. Something I found difficult was the silence and having to stay for the full 2 hours, as I had finished my exam in the first 1:15 and had to sit there for 45 minutes in silence. I did not do anything at home to help me prepare because I did lots of preparation work in class, and I felt I didn’t need to. Looking back, I think I should have done at least a little bit of work on just the basics. After the exam I felt partly confident because the exam was not as hard as I believed it was going to be.

Science-Egg drop

Aim: The aim of this egg-drop experiment was to learning about forces and motion. The idea of the parachute test was to see the real-time effects of gravity and different forces on an object. and how different designs equate to different fall times, and how safe the egg is when you drop it.

Research: To make sure our parachute was as effective as possible, we did lots of extensive research on the best types of parachutes and how to create the most lift/resistance to protect our egg. After a lot of consideration, our group decided on a hot air balloon design with a plastic dish as the basket.

Method:                                                                                                                                                                                                                                                                                                                     1) The first step of this process was planning. This is when we put all our research together and sketched a design incorporating the features of a parachute balloon and a basket filled with bubble wrap to cushion the egg as it landed.                                                                                                                                                                                                                                    2) The next step was to actually build the design we had planned. To do this, we created a list of all the materials we needed; This included bubble wrap, a plastic sheet, a plastic container, string and of course the egg. We then built it, and we had a little trouble connecting the string to the plastic dish, but we ended up melting the plastic and creating small holes around the edge.                                                                                                                                                                                                                                                                                            3) Once we had done these two steps, we then had to drop it from M13 into M9, which was the main show. With our arms straight out in front of us, we dropped them off the ledge.

Results:                                                                                                                                                                                                                                                                                                                      Luckily, ours survived with no injury sustained, unlike the control egg that we dropped with no parachute or cushioning to protect it, which ended up dying a quick death as it smashed on impact.

Discussion:                                                                                                                                                                                                                                                                                               Some of the parachutes fell faster than others because of the lack of air resistance/lift that the parachutes should have provided. Some also fell faster because of the weight of the basket that the egg was sitting in. Because of the extra weight, it increased the force of the gravitational pull, making the up and down forces unbalanced and the gravitational pull larger than the lift force.

Conclusion:                                                                                                                                                                                                                                                                                                          I would improve our parachute design next time by making the basket that the egg is in lighter because the extra weight made it fall faster. But overall, I think our design was pretty good.
