Forensics - Footprint Analysis

Hi, guys today I will be sharing what we have been doing in Forensics. We have been learning about different shoe prints. We had to identify different types of shoes; a footprint can be left behind at a crime scene. It can be transferred to a surface or left just as an imprint. We identify the pattern, random damage, worn out, or size. My task today is to show you how to analyse a footprint. 

As you can see with the image on the right there are types of ways that people stand. With the image below you can see we can identify the types of shoe prints. When knowing the shoe pattern at the bottom we can tell the size of the shoe, the brand in some cases and how old it may be. 

LET IDENTIFY A SHOEPRINT TOGETHER

These shoeprints are from the internet but we can still find out the type of print the shoe had left behind. I personally think that this type of shoe print would go under Piecewise Lines. Hope you enjoyed my blog post about analysing footprints. BYE! 

Forensics - Science

Hi, guys today I will be sharing what I have been doing for my passion project, which is forensics. We have been learning the basics of forensics so we can get a better understanding of it. I had to make a DLO sharing what I have learnt this past week. I have so far enjoyed learning about forensics. Do you know what type of fingerprint you have? Here is my presentation. Bye!

Human Rights - Social Studies

Hi guys, for the past few terms, we have been working on human rights and our rights as humans. We had to make a blog post showing all the things we have learned throughout this topic. We learnt about our human rights, referencing, the dot-jot method in taking notes, and more. I found it exciting learning about the Native Americans during the lockdown and learning about the Dawn Raids.   

We have learnt about The Universal Declaration of Human Rights (UDHR). The UDHR is an international treaty that has 30 articles of what rights a human being has. This was established in 1945 after both world wars. These aren't laws but more like values, even these articles emphasising the rights of a human some places around the world don't respect and recognize its importance.      

What are human rights? 
Human rights have the basic right to freedom that belongs to every person from birth until death.

Who do you think to have human rights? 
Every person had the right regardless of where you live, what you believe and how you choose to live.

Why do you think human rights are important? 
Most importantly, these rights give us the power and speak up and challenge poor treatment from a public authority. 

Can you think of a time when you or someone you know wasn't shown human rights? Personally, I don't remember or know anyone that has been mistreated or wasn't shown human rights.  

Rank These Rights
Most Important 
To live 
To live freely
To have clean water and food 
To have free speech 
To not be tort5ured 
To have education 
To have a fair trial
To get married 
To have religious beliefs 
Least Important

Our task was to make a poster summarising all 30 articles of the Universal Declaration Of Human Rights (UDHR). This poster needed to be presented to a high standard and needed to include images or illustrations I made this poster using Piktochart. I also added a small paragraph talking about Eleanor Roosevelt because I personally think she was an important part of the UDHR.

Native American Inquiry

I will also be sharing what I have been doing in social studies while in lockdown. We are learning about social justice, our task was to pick a topic for example Child Labour, Jew in Nazi Germany, the Death Penalty, and etc. I chose to do Native American because it seems like a very interesting topic. Going into the topic the only thing I knew about Native Americans they were indigenous people of America. I researched who they were, where they are, and how they were discovered? When learning about how they were discovered and how their name came to be American Indians I was very fascinated so I added an extra slide taking about it. I have also added an extra slide showing connection with Māori and Native Americans and there are a lot of similarities between the two. Here is my presentation about Native American Reservations.

Dot-Jot Method

While learning about human rights we learnt how to take notes using the dot-jot method. When using the dot-jot method you need to write down key information, keyword, important dates and important events from the video or website you're getting your information from. I personally found this very quick and easy and used it a lot. This also helped me put my notes in my own words when it came to writing. This is an example of myself using the dot-jot method was when I did my Holocaust work. 

 

Referencing 

While also learning about the dot-jot method we learnt how to reference sites, videos or anything that needs to be credited by the author. Referencing gives the author credit for their work. I think that is really important we reference because if you don't, it counts as plagiarism (copyright). We used APA (American Psychological Association) which is a style of referencing. The website we used to help us reference sites, articles, images, or videos was ReferenCite. Here are some referencing I did for my work.  

Invasion Of Parihaka

After learning about the referencing and the dot-jot method we had to learn about the Invasion of Parihaka. I found Parihaka an interesting part of New Zealand history and I think every New Zealander should know the history behind it. Here is another presentation I have made. Enjoy!  

Dawn Raids

We have been working on a case study. I am doing Dawn Raids because I found it interesting. We had to answer questions and make a presentation showing our answers. The Dawn Raids began in the 1970s and is when the government targeted the pacific communities in New Zealand. I won't tell you everything but if you would like to know read my presentation. Here is my work on the Dawn Raids. 

We are DONE! 

Our final task was to write paragraphs about a chosen topic. My topic is the Final Solution. I found this an interesting topic because Adolf Hitler was the leader of the Nazi Party in Germany during the Holocaust. He is known for being one of the most powerful and notorious political leaders. Here are my paragraphs about the final solution. 

The “Final Solution Of The Jewish Question” is the term used by many German Nazi leaders, it referred to the Holocaust or the genocide (mass death of a single ethnicity) of European Jews. The Holocaust was systematic and state-sponsored by Germany who targeted European Jews. It began in 1941 and lasted until May 1945. The German Nazi Party murdered six million European Jews; the party's leader, Adolf Hitler, was Germany's ruler from 1933 to 1945. Germany killed six million Jews because Jews were supposedly a threat to the German community. Germany referred to itself as "racially superior," which implies that one group is superior to another and believed that Jews were “inferior” meaning they were below Germany. The Nazi Party envisioned killing eleven million Jew but succeeded in killing six million. Germany also targeted groups with political, ideological, and behavioural grounds. Alongside Germany, allies and collaborators also targeted communists, socialists, Jehovah’s Witnesses, disabled people and homosexuals. European Jews lived in countries Nazi influenced during world war ||; Nazi excluded Jews from German economic, social, cultural life and pressured them to migrate. 

In 1939, the anti-Jewish policy escalated to imprisonment and murder. The Nazi Party established ghettos (confined areas designed to isolate and control the Jews). Jews were deported to other ghettos all around Europe; ghettos were very unsanitary, overcrowded and had inadequate food. Nazi leaders also established three killing centres in Poland—Belzec, Sobibor, and Treblinka to murder Jews. Police and German SS (paramilitary organization under Adolf Hitler) murdered nearly 2,700,000 Jews in the killing centres. This was by asphyxiation with poison gas or by shooting. By 1941, the SS and Police introduced mobile gas vans. They were specially designed for ongoing shooting operations. In these trucks there would be exhaust pipes with poisonous carbon monoxide gas, killing those who were inside. In the 1940s many Jews and many other victims were forced into labour by the Nazi Party. Nazi established concentration camps which were detaining centres. There were pointless, humiliating and had no proper equipment, clothing, food or rest. Prisoners worked to death! Camp prisoners were forced to work in conditions deliberately that led to illnesses, injuries and death. For instance, in many camps, prisoners would run up and down steps carrying heavy boulders daily.

In article 5 of the Universal Declaration of Human Rights, it states that “No one has the right to inflict torture, or to subject anyone else to cruel or inhuman treatment.” Two out of three Jewish were killed during the holocaust, therefore did not uphold this human right.

In conclusion, I really enjoyed this topic because I learnt about so many problems we faced through time around the world and the problems we are still facing. During this topic, I learnt about the Universal Declaration of Human Rights, Native Americans, the dot-jot method, referencing, the Invasion of Parihaka, Dawn Raids, the final solution and the list goes on. I found all of the things I learnt useful and will help me in my future studies. If you are still reading this very long blog post, thank you. Bye!

House Plan - Science & Maths

Hi, guys today I will be sharing what we have been doing in the last weeks of science and maths. We have been designing our own houses. In maths, we first had to choose a house plan out of three and then calculate the area and perimeter of it. In science, our task was to calculate the voltage and current of each light bulb and the total current in the house.    

Aim: To design a house plan including light bulbs and calculate the voltage and current of each bulb. 

Method: There were three choices of a house plan, I chose LE (Level Exceeded). In this, we needed 12 light bulbs and 5 rooms.

Results: 

Plan of House: 

With 5 Rooms and 12 Light Bulbs

Ohm's Law Calculations And Parrell Circuit Digram 

Discussion:  

As you can see in this table the current has an abbreviation of A, voltage has an abbreviation of V and Ohms abbreviation is Ω. You can see I used all three of these abbreviations in my circuit diagram. 

To calculate the voltage, current or resistance you need to check out these three triangles I have made. An average house in New Zealand has 100 Amps of current. My current in total was 21 Amps; I think that it was a realistic amount because this is only the current of the light bulbs.   

Current: An electric current is a stream of charged particles, for instance, electrons or ions. 

Voltage: Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating light.

Resistance: Resistance is a measure of the opposition to current flow in an electrical circuit.

To find the voltage of something you need to multiply the current and resistance; to find the current you need to divide the voltage and the resistance and to find the resistance you need to divide the voltage and the current.  

Quick Question: What are fuses? How are they used in a house?

A fuse is an electrical safety device that operates to provide overcurrent protection of an electrical circuit. Its primary component is a metal wire or strip that melts when too much current flows through it. In homes, fuses are used a lot, for instance, appliances like televisions, refrigerators and computers have fuses and can melt when too much current flows through. 

Conclusion: I personally enjoyed this topic I found it exciting learning about electricity in houses and how to design a house with electricity. If I were to do it again I would change the layout of my house and use a larger house plan. Well, this concludes my final blog post about electricity, I enjoyed learning about it. My favourite part was making the house. Thank you for reading. Have a great day bye! 

Gymnastic - P.E

Hello, guys, as you can tell by the title for the past few weeks we have been doing gymnastics in P.E. We have been working on six apparatus the Beam, Mini Tramp, Parallel Bars, Floor/Mat, Trampoline and Horizontal Bar. Personally, my favourite was the Mini Tramp, Horizontal Bard and the Floor/Mat. One of the challenges I faces was trying to lift myself up on the Parallel Bars but after a lot of practice, I finally was able to lift myself up and walk along the bars. Something I achieved was doing a dive roll on the mini-tramp which I found to be fun and exciting. At the end of Gymnastics, we had to do an assessment and record all the moves we were able to do. Here is my assessment hope you enjoy it. Bye.

Electricity Final Blog

Hi, guys, today was our last day learning about electricity. For our final blog, our teacher told us to study these topics and make a blog post showing was we have learnt. When learning about electricity we learnt about static electricity, current electricity and electromagnets. At the end of the topic, we also did an experiment about electroplating.   

SERIES Circuit

In a series circuit, there is only one path through which the whole current flows. Series circuits are used around the house for example water heaters, lamps, freezers, and refrigerators are some appliances. The electric current in a series circuit goes through every part of the circuit.

PARALLEL Circuit 

A parallel circuit is a circuit with many different paths for the electricity to travel from. The wiring system of a house is an example of parallel. One single electric power source supplies all the lights and appliances with the same voltage. If one of the lights burn out, the current will still flow through the rest of the lights and appliances, but if one bulb burns out in a series circuit, the entire circuit is broken. Parallel circuits can consume more power when compared to series circuits. 

How does LIGHTNING work?

If the ground is hot then the air will be hot as well. The warm air rises and as it rises water vapour cools it down and forms clouds. In the tops of clouds, the temperature is freezing and water vapours turn to ice. Now, these clouds become thunderclouds, lots of small bits of ice bump each other as they move around. All these collisions build up an electrical charge. When this happens the whole cloud fills up with electrical charges over time. Lighter and positively charged particles form at the top of the cloud. Heavier and negatively charged particles sink to the bottom of the cloud. The positive and negative charges grow larger and create a giant spark called lightning. Lighting occurs between the two charges within the cloud. This is like static electricity but much bigger. Mostly lightning happens inside a cloud but it happens between the cloud and the ground. A build-up of positive charges on the ground attaches the negative charges at the bottom of the cloud. The grounds positive charge focuses around anything pointing up like trees, lightning conductors and even people. The positive charge from the ground connects with the negative charge from the clouds and creates a spark of lightning. 

What is a MAGLEV train?

Maglev train is a system of transport that uses two sets of magnets. One to repel and push the train up the track and the other to elevate the train to go ahead. This is taking advantage of the shortage of friction (the resistance that one surface or object encounters when moving over another). Maglev technology was first developed by English inventor Eric Laithwaite and opened in 1984 in Birmingham. Maglev transport is operational in only three countries Japan, South Korea and China. 

How does a MOTOR work?

An electric motor works by converting electrical energy into mechanical energy this generates motion. Force is made inside the motor through the interaction between a magnetic field and winding alternating (AC) or direct (DC) current. Alternating Current (AC)  is an electrical current that directs the flow of electrons that are switched back and forth at regular intervals or cycles. Direct Current (DC) is an electrical current that flows consistently in one direction. You can use a motor to create an electric current.

How does a SPEAKER make a sound? 

Speakers convert electrical energy to mechanical energy or motion Mechanical energy compresses air and converts the motion into sound energy or sound pressure level (SPL). An electric current passes through a coil wire, this produces a magnetic field. In speakers, a current is sent through a voice coil which produces an electric field that interacts with a magnetic field of the permanent magnet attached to the speaker. Like charges repel each other and different charges attract. As an audio signal is sent through the voice coil and the musical waveform moves up and down, the voice coil is attracted and repelled by the permanent magnet. This makes the cone that the voice coil is attached to move back and forth. The back and forth motion creates pressure waves in the air that we perceive as sound.

 

Electroplating with Copper Experiment 

In science, we did an experiment called electroplating with copper. Electroplating is the process of using electrodeposition to coat an object in a layer of metals. There are also specific types of electroplating such as copper plating, silver plating, and chromium plating. The surface can be metal or even plastic.

Equipment:

1. Power Supply
2. 2 Wires with clips
3. Copper Sulfate Solution
4. Copper
5. Beaker
6. Something you want to plate. 

Method:

1. Put your Clips onto the positive and negative terminals of your power supply. Attach the copper to the positive wire and the metal you want to plate to the negative wire. 
2. Put the copper sulphate solution in a tall beaker and put the copper and item in the solution. Avoid the clips entering the solution. 
3. Set your Power Supply to 6 Volts and turn it on! Leave for several minutes and see the results.  

Results: After doing the experiment the results of the metal was coated. Here are our results.

Discussion: The copper in the blue liquid was Cu2+ with an electrical current turned into Cu (Orange Metal) on the negative electrode.

In conclusion, I found learning about electricity very interesting and I would love to learn more about how Maglev Train work and the history behind it. Thank you for reading my blog post about electricity and hope you learnt something new. Have a good day bye!
