Alberta Education Sciences Course Sequence

REQUIRED FOR HIGH SCHOOL DIPLOMA: One grade 10 and one grade 11 science course.



Science 10 is the prerequisite for all 20 level science courses (the exception is the Science 14/24 stream). Science 10 is a general science course that includes units in biology, chemistry, physics, and energy flow in global systems. Science 10 is a good fit for students who achieved a mark above 60% in Science 9.

SCIENCE 10 Extended

Science 10 Extended helps students who have had difficulties with Science, obtain Science 10, so they can move on to Science 20, or potentially one of the other 2o level sciences (Bio, Chem, Physics)..  This course allows students to take Science 10 over a longer period of time, taking Science 14 in the first 3-4 months of the year, while improving their skills in numeracy and Science skills and knowledge, and then Science 10 in the next 6-7 months.  It is a full year science course, which when completed will provide students with 10 credits and completion of Science 10 and 14..     

SCIENCE 14 - 24

This program sequence meets the basic requirements for an Alberta High School Diploma. Science 14 is a good fit for students who achieved a mark below 60% in Science 9.


SCIENCE 20 - 30

Science 20 and Science 30 are general science courses that cover topics in biology, chemistry, physics and earth science. Students are encouraged to consider taking Science 20 and then 30 if they achieve a mark of between 50 and 60% in Science 10. Typically students do not enrol in Science 20 if they are taking any other 20 level science course.

Science 30 is accepted for entrance to all Alberta universities. Any 20 level science course can

be used as a prerequisite for Science 30. You do not need to take Science 20 in order to take Science 30. Many students find that the mark they receive in Science 30 helps them increase they average they use to apply to their post-secondary program.

BIOLOGY 20 - 30/ AP20 - AP30

This program sequence begins in Biology 20 with a study of ecology, human physiology, photosynthesis/respiration and evolution. Biology 30 continues with human physiology and also covers cellular reproduction, genetics and population biology.


This program sequence begins in Chemistry 20 with a study of bonding, solutions, acids and bases and chemical analysis. Chemistry 30 examines thermochemistry, electrochemistry, chemical equilibrium, and organic chemistry.
