What your teen is learning

Chemistry 20

Your teen will use models to help them understand and describe simple molecular substances. In the lab, they’ll explore the behaviour of gases, and they’ll apply this knowledge to natural processes like breathing and to technologies like gas turbines. Your teen will write and balance chemical equations, analyze chemical reactions, and learn to predict the products, states and yields of different reactions. They will also relate ion concentrations to pH and pOH of acidic and basic solutions. For more about Chemistry 20, refer to the program of studies.

Chemistry 30

Your teen will explore different uses and applications of energy associated with chemical reactions. They’ll analyze, interpret and quantify thermochemical changes and electrochemical changes. Your teen will compare organic and inorganic compounds, create models of organic compounds and describe the significance of organic chemistry in industry and our daily life. They will also examine the factors that influence equilibrium shifts in acid-base reactions, and they’ll calculate concentration of ions and the pH and pOH of acidic and basic solutions. For more about Chemistry 30, refer to the program of studies.

How your teen is assessed

Learning is assessed using a variety of tools and strategies within the classroom. Ask the teacher what methods they are using. The different assessment methods tell you, your teen and your teen’s teacher about your teen’s strengths, the areas in which they might grow and how well they are doing throughout a course. At the end of the course, your teen will be assessed and their achievement will be reported so that you know if they have achieved the expected learning outcomes for the course.

At the end of the 30-level course, your teen will write a provincial diploma examination. There are three main purposes for the diploma examination:

  • to certify the level of individual student achievement in the course
  • to ensure that province-wide standards of achievement are maintained
  • to report individual and group results.

Your teen’s final mark in the 30-level course is determined by taking 70% of the school-awarded mark and adding it to 30% of the diploma examination mark. Your teen must achieve a final mark of 50% or higher to obtain credits for the course. General and course-specific diploma examination information is available to help you and your teen.

Resources to help your teen

A variety of digital and print resources, developed by publishers, Alberta Education or Alberta teachers, are available to help students learn. Teachers may select, and bring into the classroom, numerous innovative and creative resources to create rich learning experiences for your teen.
