Periodic Table

Your task today is to examine the periodic table below (click on it to enlarge).

  • Go to pollev.com/mrsbarth
  • type 10 things you can see on the periodic table. Put a comma between each item.
  • example    hydrogen, oxygen

 

Part 2:

  • Open WORD ANTICIPATION GUIDE
  • Fill in the first column with what you think the meaning is.
  • In column 2 put a number for how confident you feel about your meaning. (1 is very confident, 2 is somewhat confident, 3 is not confident at all).
  • Email your guide bt@wellingtonsc.vic.edu.au. make sure you rename it first to include your name.
  • Save the file, you will need to refer to it again in future lessons.

 

Body Systems

Today we are investing different body systems.

 

Your task is to open the following animations, watch the video and answer the questions. When you have finished this you will need to email your answers to me at bt@wellingtonsc.vic.edu.au.

 

Colour

Your task today is to investigate colour. You will use simulations to answer questions and investigate the properties of colour.

Colour

 

Click on the simulation run it. If it doesn’t work, use the link below the image instead.

Color Vision

Click to Run

 

Use the animation at the following address to test the hypothesis below: http://phet.colorado.edu/en/simulation/color-vision

Hypothesis:

An object will appear to be a certain colour because it reflects that colour back to our eyes while absorbing all other colours.

Method:

1.  Go to the “Single Bulb” section of the animation.

2.  Use the on/off button make the object appear then reappear.

3..  Move the slider at the bottom to change the colour of the object that the person is viewing.  The colour that they see can be seen in the though bubble above.

Discussion:

1.  What colour is seen when there is no filter?  Why is this colour seen?

2.  When the filter is purple what colour light does the eye detect?  When it is red?

3.  What colours of light hit the surface of the object?

4.  What happens to the other colours to make the object appear blue?

Conclusion:

Write a short paragraph which answers the following:

-Was the hypothesis correct?

-What allowed you to conclude the hypothesis was correct?

-Why do we do we see objects as being coloured?

 

Email your report to me when you have finished. (Use gmail through your moodle login, my email is bt@wellingtonsc.vic.edu.au)

Download this document and answer the questions. Email the document back to me when you have answered them.

Pathologist

 

  • Before becoming a pathologist people need to study all the sub-disciplines like anatomical, chemical, clinical, forensic, general etc.
  • After studying them in a medical university then they can proceed being a specialist.
  • Doing practical experiments and being examined before becoming a pathologist and are then licensed by the uni as a pathologist.
  • They work in collaboration to clinical scientists. They have 2 major divisions which split up to pathology and anatomical pathology.
  • In pathology they test different samples as hair, DNA, blood, saliva and urine. They also test any foods or drinks consumed by the victim.
  • In anatomical pathology they study different chemicals found in the victim’s body itself.
  • Pathologists always work indoors in the laboratory because they need different equipment to study their substances.

Forensic Biologists

Forensic Biologist

 

A forensic biologist examines blood plus any other body fluids, hair, bones, finger/foot prints, plant & animal to help identify victims and support a crime investigation by finding a criminal. Their jobs are made much easier with modern leading-edge technology which is used to analyse biological evidence found on clothing, weapons and any other surface which can determine cause and time of death. After analysing evidence and finding something a detailed log must be written and not leave anything out because it is needed in court.

 

Becoming a forensic biologist usually takes 4-8 years of studying to complete a degree in forensic science. Studying more degrees in things like biology, botany, chemistry, physics, dentistry or medicine could give more chance entry into this job.

Forensic biologists usually work off site of scenes and in labs with samples others have collected.

Ballistics Expert

Ballistics expert
They collect, studies analyse evidence related to ammunition and firearms.
They need a bachelor degree in science and criminology. Train in mechanical engineering or metallurgy. Useful in learning chemistry, maths and physics.
They work on site to look for any bullets firearms used in the murder.

 

What they do – A ballistics expert collects, studies and analyses evidence relating to ammunition and firearms. They also study the tragedy of the bullets, and the characteristics after they’re fired. So basically anything related to weapons and bullets, they’ll be there at the scene collecting, studying and analysing. Many experts are employed by police forces and are hired by private agencies.

 

Career Requirements – To become a Ballistics Expert, you’re required to finish school. Many have a bachelor’s degree in forensic science and criminology. Police officers with experience in firearms can become a Ballistics Expert by attending some training courses without earning a degree.

 

Training to become a ballistic expert can include:

  • Ammunition
  • Crime scene search
  • Evidence handling
  • Expert witness testimony training
  • Fields of law
  • Firearms assembly/disassembly
  • Firearms identification
  • Gunpowder and primer residue
  • Microscopy
  • Wound ballistics

They start collecting the evidence relating towards weapons and bullets on the crime scene. They then bring it back to the lab for further investigation and analysing.

 

 

Forensic Photographers

Forensic photography is crime scene, or accident-scene photography. It is all about making an accurate, photographic record of an event, after-the –fact, for the benefit of a court case or other legal proceeding. They may be taken specifically for documentation, analysis, intelligence, or for court presentations. To be used in court, pictures must be allowed under the rules of evidence that apply in a particular jurisdiction. These rules will indicate whether the images provide information relevant to the court and thus can be admitted as evidence.

Forensic photographers have to be very good at making photographs that tell the full story of a scene. That included detail images as well as those that provide overall context. A good series of forensic photographs would record as much as can be seen in a scene as possible, to the satisfaction of all parties whose job is to accurately dispense justice.

To become a forensic photographer, you need to be trained in police officer and completed in-service photography course. Most people like to experiment with photography and we can’t really do that. And when you join the police you’ve got to spend a fair amount of time on the street before you can go into any specialist area. When you join the photographic section you do a four-week course at Police College, you sit units and to be fully qualified takes five years. They are looking at a certificate that could potentially be used around the world.

This is not one of those photography jobs to be taken lightly: forensic photographs can make or break a criminal case, and the subject matter is often disturbing.
