Group 4

The course in group 4 is the Natural Science or Experimental Science. Natural Science is the knowledge about the nature and identifying the world. IB provide the students 5 main subjects that is offeren in HL and SL for group 4 which are Physics], [[Chemistry, Biology, Computer Science, and Design Technology. These 2 other subjects are provided in SL only, Environmental Systems and Societies, and Sport, Excercise and Health Science[1]. IB programme in Stella Maris does not provide these all subjects. they only provide Chemistry and ESS in the group 4. They also have Physics and Biology but they put it in Group 6.

Structure
All group 4 subjects except ESS and Computer Science, follow roughly the same format. Each subject has its Subject Specific Core (SSC), example, material taught at both the standard and higher levels. Students sitting the Higher Level examination study the additional Higher Level material. Lastly, there is a list of options for each subject from which two are chosen. Higher Level students are sometimes unable to choose certain options that are available to Standard Level students because the additional Higher Level already covers it. Ideally, students choose the options based on their own abilities and preferences, but in practice the options are usually chosen by the school (based on the school's scientific facilities as well as the discretion of the instructor). Students spend one-quarter of the 150 hours of SL instruction (240 hours for HL) doing practical work in the laboratory. Group 4 subjects at the Standard Level are tailored for students who do not see themselves in further science instruction after leaving the programme.

Assessment
The assessments for the group 4 course are

-Internal Assessment

-External Assessment:


 * Paper 1 : Multiple choice questions on the SSC (45 minutes SL, 1 Hour HL)


 * Paper 2 : Free response questions on the SSC (1Hour 15 Minutes SL, 2 Hour 15 Minute HL)


 * Paper 3 : Free response questions on the options (1 Hour SL, 1 Hour 15 Minute HL[2].
