Group 4 Sciences

Biology SL  [IB Course Outline]
Biology is the study of life.  IB Biology deals with the biology of the very small(molecular biology) right up to the biology of large systems such as ecology. Experimental work is essential throughout the two years of both courses because it permits students to explore biological concepts and learn how scientists and the students themselves can add to biological knowledge. This practical work is continually assessed and amounts to 20% of the the mark each semester.  A 10 hour individual student designed lab will be submitted to the IBO as the IA mark which will amount to 20% of the final IB mark.  This investigation may take place during the latter part of the second semester of the first year or the first semester of the second year.

Recommendations:  High level of interest in biological sciences and/or medicine; work ethic; Developed number sense including ability to use/understand averages, percentage, very small numbers and very large numbers
Prerequisites: none.

Biology HL   [IB Course Outline]
In addition to SL content, at HL there are five additional topics in which the core topics are studied in greater detail: nucleic acids; metabolism, cell respiration and photosynthesis; plant biology; genetics and evolution; and animal physiology plus the Option  Ecology and conservation.

Recommendations:  High level of interest in biological sciences and/or medicine; work ethic; Developed number sense including ability to use/understand averages, percentage, very small numbers and very large numbers
Prerequisites:  Minimum of OLA 5 in Grade 9 & 10 Science or recommendation of science teachers

Chemistry SL  [IB Course Outline]
IB Chemistry deals with the “big stories” of Science e.g. the theory of the atom, equilibrium, the relationship between the atomic model and chemical behaviour. Experimental work is essential throughout the two years of both courses because it shows students how the concepts of Chemistry are applied to predict and explain observed chemical behaviour. This practical work is continually assessed and amounts to 20% of the final exam mark in both HL and SL courses, a very important exam component. There is a wide range of quantitative and qualitative material studied. Topics include atomic theory which provides a basis for understanding energetics, kinetics and equilibria, acids and bases and redox as examples of reaction types and organic chemistry. There is continual assessment of laboratory work during the two years.
Prerequisites: successful completion of Integrated Science recommended or recommendation of teacher. Concurrent study of IB Standard/Higher Level Maths strongly recommended.

Chemistry HL  [IB Course Outline]
There is a wide range of quantitative and qualitative material studied. Topics include atomic theory which provides a basis for understanding energetics, kinetics and equilibria, acids and bases and redox as examples of reaction types and organic chemistry.
The choice of options depends on the students in the class.
There is continual assessment of laboratory work during the two years. Although the topics are similar to those of standard level, they are studied to greater depth.
Prerequisites: successful completion of Integrated Science or recommendation of teacher. Concurrent study of IB Standard / Higher Level Maths is required.

Physics SL  [Course Outline SL]
This course provides an introduction to key topics in classical and modern physics, along with insight into the methods used by scientists. The course places emphasis on mathematical and problem-solving aspects of physics. There is continual assessment of laboratory work during the two years.
Recommendations / Requirements
Concurrent study of IB Standard/Higher Level Maths strongly recommended. Both SL and HL level students should enter only if they possess a keen interest in the physical sciences. SL level candidates should enter with no less than a high 5 or 6 in their prior maths classes.Higher Level Physics requires a greater depth of mathematical and concept analysis ability. Physics concepts are all supported with mathematical relationships and assume a good competency in both science and maths.

IB Physics HL   [Course Outline HL]
This course provides a detailed study of key topics in classical and modern physics, along with insight into the methods used by scientists. Topics are treated rigorously and mathematical analysis is an essential part of the course. Assessment of laboratory work continues throughout the two year programme.

Prerequisites
- Grade 10 Math Score of 6 or 7 only
– Grade 10 Science Score of 6 or 7 only
– Concurrent study of IB Standard/Higher Level Maths is required.

Environmental Systems and Societies SL  [Course outline SL]
Using a systems approach, the course provides students with a coherent perspective on the interrelationships between and within ecosystems and societies; one that enables them to analyze environmental issues, evaluate strategies for addressing them and adopt an informed personal response. Practical work in the laboratory and in the fields is an integral part of the course and is assessed through a portfolio of work that students build up throughout the two years. This course is only offered at Standard Level.
NOTE: students should be aware that the exam requirement for this course involves the writing of essays which differs from the other IB sciences.
Prerequisites:  one. Environmental Systems and Societies can count as a group 3 AND a group 4 subject, and as such, a good scientific understanding is essential and \ Mathematical and IT skills arealso essential since students will be required to process, present and analyse data collected throughout the course. While some scientific practice is involved, this is largely as a method for collecting data, which is then considered on a more discussion based standpoint. This course suits students who prefer a discussion style environment as compared to a more traditionally scientific academic one.

Computer Science SL / HL  [Course Outlines HL / SL]
This course is about problem solving using a computer. The course deals with an understanding of logical problem solving as well as computer programming. To logically solve problems, the students learn to break a problem down to simpler problems that can be more easily solved. With respect to programming, the students begin with very simple programs and during the two years advance to the point where they can write well-developed programs to solve interesting problems. To aid in learning programming the students also learn how a computer works and form a realistic view of their applications and limitations.

Recommendations / Requirements:
There are no prerequisites. This course is highly recommended for all students who like working with computers or feel that they will need programming in their future studies, in particular,  Computer Science, Engineering, Mathematics or Science. It is also increasingly becoming important in the Social Sciences. This course is not about using applications including games.

Sports Exercise and Health Science SL only    [Course Outline SL]
This course combines physiology, biomechanics, psychology, nutrition and anatomy. Students carry out practice (experimental) investigations in both laboratory and field settings. The course involves 80 hours on the core topics of: anatomy, exercise physiology, energy systems, movement analysis, skill in sport and measurement and evaluation of human performance. In addition students spend 30 hours studying two of four options: optimizing physiological performance, psychology of sport, physical activity and health or nutrition for sport, exercise and health. The course is examined via internal assessment comprising short and long-term investigations and the group 4 project.  The external culminating examination comprises three papers: paper 1 multiple choice questions based on the core topics, paper 2 – data based questions and short answer questions on the core topics and paper 3 comprising short answer questions on the options

Design Technology SL / HL      [Course Outline SL / HL]
Through studying design technology, students should become aware of how designers work and communicate with each other. While the design methodology may take on a wide variety of forms, it is the emphasis on a practical approach through design work that characterizes this subject. Students apply critical thinking and design skills using the design cycle to structure the inquiry and analysis of problems, and the development and evaluation of solutions (model, products, prototypes or systems). The courses covers the core topics: human factors and ergonomics, resource management and sustainable production, modelling, raw material to final product, innovation and design, and classic design. HL students cover an additional four topics: user-centred design, sustainability, innovation and markets and commercial production. The course is assessed via three examination papers comprising multiple choice, dated-based short-answer and extended response questions and a paper 3 at HL on the extension material. In addition, students complete an individual design project and the Group 4 project where they collaborate with students from the other sciences.
