My project post

 Seven weeks ago we started out projects for the end of the year. Chloe and I decided to create an app, an app that can solve all of your homework problems. At the start of the seven weeks, we went on app lab and followed the tutorials that they have on their site to create an app. As we went through all of the tutorials we learnt how we could potentially create our own app. Our Homework help app has a range of subjects that you can choose then ask a question about your homework. After that, it brings you to another screen to wait for your answer process. 

Chloe mainly did the design/colours of the app while I did more of the coding side. We decided on our colour theme (Purple.) 

I have never really done digital tech before this but it is very interesting with all the types of codes and ways to program programs. Our app has working buttons and everything was completed by ourselves. When you click on the subjects button it takes you to a page with all the 6 subjects we have. There is also a check off planning tool that you can check off once you have done your task and there is a notes section that you can write your notes on.  If I were to do this again I probably would add more coding and make the app more interesting with more pops of colour. 

Reflection

For the past term in Forensics class, we have been learning everything that would lead up to the point that we create our own crime scene in a miniature version. We learnt about blood spatter patterns, fingerprints and DNA profiling. My group and I decided that we would make ours in a small shoebox with a road lengthening out from one side to the other. We created a crime scene sketch before we did anything else to plan out our work. If I were to do it again I would work more together as a group instead of doing everything separately. Later on, I did an autopsy report not getting too much into detail though. We created a presentation about the crime (Highway to Hell) We had to create a title with a pun in it. Our deceased body is made out of green felt, therefore the name "Mr. Green."

Murder Scene - group project write up.

"Highway to hell": A mid-age man was found dead on the side of the road. With hardly any information about this deceased man Police only have found his last name "Mr. Green." Witnesses describe the collide as somehow accidental. Other drivers claimed they saw someone walking around the roads carelessly just under an hour before the body was found. On the body, there were tire tracks with gashes of blood on him. The police assume he was run over. The tire tracks folding across his body are also trailing down the road for 1km. The location has been blocked off where the man's body still lays as police investigate the situation further. 

Debating

For the past few weeks, our class has been learning about debating. We have learned how to properly write a debate sensible paragraph also learning how to properly use our voices to make everyone believe our opinions and agree with us. 

I personally have enjoyed this class and it has been interesting and I have learned a few things I didn't know before. This class hasn't been that challenging but it would have been a little bit more fun if it was more challenging. 

Next year our school is going to have a debate team as we don't have one now. I have signed up for it and am excited to see what it will be like. But I think I need a lot more practice to be able to debate properly with another school. 

Shoe~Footprint Analysis

Shoe/Footprint analysis is analyzing a shoe/footprint. You can analyze a shoe by the design/patterns on the soul of the shoe there can be many types of designs on a shoe print eg. circles, lines, or both. Forensic Scientists can also figure out what shoe they are by the different arches, the length or width of the shoe/foot, the shape, and if it is worn. 

If you were a forensic scientist you would be looking at all the different types of evidence explained in the paragraph before, you would look at the size- because some sizes can be different, you would look at the arch and if the shoe has been worn in then you can compare between the two or more different shoes. 

Recording footprints is simple. You can use a mold to have the shape of the shoe from the ground then the Forensic Scientist washes off the excess dirt from the mold. They do this so you can analyze and find out who's footprint is who's; this can be used as evidence to figure out who committed the crime. 

What would you be looking for to help you decide who's shoe is which? 

- If you had two different shoes with two different people that had different heights, obviously there would be different shoe sizes and you could quickly figure it out by that, and from the first paragraph, I explain the different ways of analysis for shoes. 

Forensic

Forensic Science   

Forensic Science is applying scientific knowledge to law. Definition of Forensics: “Forensics is the use of scientific techniques and evidence to solve crimes is used in the legal system.”  Forensic scientists collect and preserve evidence then analyze it to help solve an investigation into the crime their jobs can vary from murder scenes to drug busts all over the country. 

We need Forensic Scientists to figure out and investigate to prove who did the crime; they collect, preserve, and genetically identify evidence from the crime scene and see if there is a match. You can find evidence in Fingerprints, Hair, Skin follicles, Blood, Footprints, and more. Genetically identifying fingerprints were discovered by Sir Alec Jeffreys.

Genetic Profiling is figuring out the DNA’s code to see if it matches up with the person. Everyone has a genetic code and each code is different. DNA is short for deoxyribonucleic acid, deoxyribonucleic acid is the instruction to make up nearly every cell in your body. There are four types of DNA, adenine, thymine, guanine, and cytosine these four types make up your DNA. Genes are a segment of DNA.

To be a forensic Scientist you need to be observant / an eye for detail to have an open mind by being observant as a scientist helps Forensic Scientists to identify and find as many clues as possible to figure out the criminal offender to do the best work they possibly can.  

Forensics Scientists are really important to have in our society because they know the scientific truth behind the crime. Deoxyribonucleic acid makes the connection between genetically profiling so the truth is pushed further out and their mind as well. 

Project

AIM: The aim of this project was to find the area of a floor plan we chose. We had to find out the current and voltage of our light bulbs in our house. 

Method: I have two bedrooms and one bathroom. The template chosen is plan C.

The amount of bulbs I have is 10, the bulbs are all throughout my house. 

Results: I have 5 pathways for my circuit with an area of 150.3175msquared. The areas of each room

Bed1: 28m^2

Bed2: 12m^2

Bathroom: 12m^2

Entrance: 25m^2

Triangle: 7.5m^2

Semicircle: 9.8175m^2

Kitchen/Living: 36m^2

___________________________________________________

The voltage of pathway one is 200V with one lightbulb. Pathway two, each of my lightbulbs is 66.67V,

pathway three is 50V on each bulb,

pathway 4 200V and the same with the last pathway. 

The total current of my house: 28.67

Discussion:

Voltage is the amount of energy given by the “source” or battery. 

Current is the rate of flow by electrons. 

Resistance is about pushing back, if you change the resistance on your light bulb the more resistance the slower the electrons. 

______________________________________________________

- What are fuses? Fuses are electrical devices that interrupt the flow of the current. It blows up when too much current flows through it. 

- How are fuses used in a house? Fuses are used to blow up when too much current flows in it, this is because it will prevent a fire. 

_______________________________________________________

The way I found the voltage of the light bulbs was by dividing the voltage from the battery by the number of light bulbs I have on each pathway/lane of the circuit. The calculations make sense because 200/4 is 50 so the amount of V in each bulb on line three is 50. 

I enjoyed doing this project because I like mathematics and physics. Learning about VIR is very interesting because I have not really heard much about this. I would not do anything differently because I am happy with the outcome of this project. Choosing a floor plan and calculating the area was the easiest part of it all as I have done that before. I didn’t know anything about VIR before learning about it so it was slightly difficult until you learn the formulae of each perspective.
