Science 20, Alberta Education, Program Resources Branch Alberta Education, 2006.
Science 20 is a general science program that continues to integrate biology, chemistry, physics and the
Earth sciences. Science 20 will concentrate on concepts and themes which unify the sciences, such as
matter, energy, and systems.
The concepts involved in Science 20 are sometimes mathematical in nature and a working knowledge of
algebra is required. The use of a scientific calculator is recommended. The units to be studied are as
Unit A Chemical Changes
Chemical changes involve a change in energy. Economically important industries in Alberta and other
parts of Canada are based upon the application of chemical principles. Students will:
1. Investigate aqueous solutions to determine conductivity and to calculate concentration.
2. Explain oxidation, reduction and spontaneity and apply this knowledge to voltaic and electrolytic
cells and to industrial processes.
3. Describe the properties of simple hydrocarbons and describe hydrocarbon-based industrial
processes that are important in Alberta.
Unit B Changes in Motion
Motion is apart of every day life and understanding the effects of force on motion has many technological
applications. By looking at applications of displacement, velocity, acceleration, force, momentum and
mechanical energy students will find the relationships between them and apply them to activities such as
safe road design, traffic accidents, and sporting goods.
Students will:
1. Describe one-dimensional motion of objects in terms of displacement, time, velocity and
2. Describe and analyze the law of conservation of momentum for one-dimensional collisions and
change in momentum (impulse) to explain how force affects motion.
Unit C The Changing Earth
Evidence from the Earth’s changing face will be explored by examining scientific evidence for climate
change, evolution, and the changes to the Earth’s surface.
Students will:
1. Analyze the scientific evidence and explanations for geologic phenomena that occurred long ago
or are taking place over a long period of time.
2. Analyze and assess the evidence to explain the theory of plate tectonics and internal structure of
3. Analyze and assess the evidence provided by the fossil record of change in the environment and
life forms over a period of 3.5 billion years.
4. Analyze the evidence of, and assess the explanations for, natural variations in the Earth’s climate
over the last two million years.
Unit D Changes in Living Systems
Energy, equilibrium, change and systems all interact in the Earth’s biosphere and multitude of ecosystems.
Students will explore how habitat destruction, ecological succession and changes to populations are being
caused by the increasing human population.
Students will:
1. Analyze ecosystems and ecological succession in the local area and describe the relationships and
interactions among subsystems and components.
2. Analyze and investigate the cycling of matter and how the flow of energy through the biosphere
and ecosystems as well as the interrelationship of society and the environment.
3. Analyze and describe the adaptation of organisms to their environments, factors limiting natural
populations, and evolutionary change in an ecological context.

 Daily Science Activities
 Quizzes
Major Assignment (6 – 10 assignments)
For 10-20-30 courses:
If the assignment has not been handed in, the student will be required to complete
the assignment for the next class. Students will have to opportunity to complete
assignments during assigned Study Halls, Lunch Hour, or After School Session for a
period of three days or until the assignments are returned. Failure to complete the
assignment with the aid of teachers’ intervention will result in a grade of “0”
Addressing the four foundations of the science curricula (STS, Knowledge, Skills, and
Attitudes) requires daily science activities that are conducted in and outside the
classroom. Feedback for these assignments are immediate and address skills/attitudes
and cannot be reproduced. If the activity is not complete or the absence is unverified a
grade of “0” (zero) will be recorded in First Class Gradebook. If the absence is verified
an “e” will be recorded in First Class Gradebook.
If a student misses an exam, the student will be required to write the exam the first or
second day they are back at class. The exam will be written at the discretion of the
instructor either during class, during lunch, or after school. A mark of “NR” will be
recorded in First Class Gradebook until the exam has been completed.
Students are required to complete assignments and hand them in on time as per instructors due
dates. If the assignment has not been handed in, the student will be required to complete the
assignment for the next class.
Attendance is required at laboratory activities. If applicable, students will be provided with the
data from the laboratory activity and required to complete the laboratory report for the next class
day to receive credits. If data is not applicable and the absence is verified the laboratory report
will be excused and an “e” will be recorded in First Class Gradebook. If the absence is unverified
a mark of “NR” will be recorded in First Class Gradebook.
For both categories of Assignments and Labs, failure to complete the assignment or lab will result
in the appointment of a Study Hall to facilitate the assignment/lab completion. Failure to
complete the assignment/lab with the aid of teachers’ intervention within 3 days will result in a
grade of “0” (zero) and the actions will be considered defiance and recorded on disciplinary file.
