Science 20
Chemical Changes
General Outcome 1: 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.
Demonstration of a Voltaic Cell
Properties of Materials
Ionic and Molecular Compounds This resource allows students to explore the differences between ionic and molecular compounds and has students draw conclusions based on an examination of the periodic table; experiments of solubility and conductivity; and observation of the state of matter.
General Outcome 2: Students will explain oxidation, reduction and spontaneity and apply this knowledge to voltaic and electrolytic cells and to industrial processes.
General Outcome 3: Students will will describe the properties of simple hydrocarbons and describe hydrocarbon-based industrial processes that are important in Alberta.

Changes in Motion
General Outcome 1: Students will describe one-dimensional motion of objects in terms of displacement, time, velocity and acceleration .
General Outcome 2: Students will describe and analyze the law of conservation of momentum for one-dimensional collisions and change in momentum (impulse) to explain how force affects motion.
The Changing Earth
General Outcome 1: Students will analyze the scientific evidence and explanations for geologic phenomena that occurred long ago or are taking place over a long period of time.
Additional Online Resources
General Outcome 2: Students will analyze and assess the evidence to explain the theory of plate tectonics and the internal structure of Earth.
Additional Online Resources
General Outcome 3: Students will will 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.
Additional Online Resources
General Outcome 4: Students will analyze the evidence of, and assess the explanations for, natural variations in Earth’s climate over the last two million years.
Changes in Living Things
General Outcome 1: Students will analyze ecosystems and ecological succession in the local area and describe the relationships and interactions among subsystems and components.
Field Study Recording Form and Pre-lab Questions
General Outcome 2: Students will analyze and investigate the cycling of matter and the flow of energy through the biosphere and ecosystems as well as the interrelationship of society and the environment.
Additional Online Resources
General Outcome 3: Students will analyze and describe the adaptation of organisms to their environments, factors limiting natural populations, and evolutionary change in an ecological context.

Science 20 Interactive Media Science 20 contains learning resources that address topics from the senior high school science curriculum: Chemical Changes; Changes in Motion; The Changing Earth; and Changes in Living Systems. The resource includes interactive Gizmos licensed from ExploreLearning.
The new Science 20 textbook includes a student CD that contains multimedia segments, handouts, suggested answers and Distance Learning Student Guides. This CD will be installed in the ICT Data folder of the server in your high school. By using the multimedia segments and activities, students will achieve many ICT outcomes for Science 20.
