Chemistry
Why study Chemistry?
Chemistry is the study of matter and energy and the interaction between them. Chemistry is everywhere in the world around you! It's in the food you eat, clothes you wear, water you drink, medicines, air, cleaners... you name it. Chemistry sometimes is called the "central science" because it connects other sciences to each other, such as biology, physics, geology, and environmental science.
Chemistry teaches useful skills. Because it is a science, learning chemistry means learning how to be objective and how to reason and solve problems.
So there are many reasons to study chemistry, even if you aren't pursuing a career in science.
Importance of Chemistry in Life
Where can your love for Chemistry take you?
The bullseye shows a selection of occupations that are related to your area of interest. Use the four education and training levels as a guide only and be sure to meet with the Careers Counsellor to discuss your career pathway.
Level 1 careers:
Usually require a skill level equal to the completion of Year 10, the Senior Certificate of Education, Certificate I or II. Australian Apprenticeships maybe offered at this level.
Level 2 careers:
Usually require a skill level equal to a Certificate III or IV or at least three years relevant experience. Australian Apprenticeships maybe offered at this level.
Level 3 careers:
Usually require a level of skill equal to a Diploma or Advance Diploma. Study is often undertaken through TAFEs or Register Training Organisations. Some universities offer studies at this level.
Level 4 careers:
Usually requires a level of skill equal to a Bachelor Degree or higher qualification. Study is often undertaken at a university.
