General
Welcome to Science 20
Technology is a critical part of science. Interactive learning objects are valuable tools for science exploration, modelling and problem solving. Interactive learning leads to the delight of inquiry in science - learning to do by doing.
You will be expected to take responsibility for your learning as you work both independently and in groups. Tasks vary from short procedural items, which will help you develop skills in the language of science, to longer tasks that require you to test either subtle conjectures or apply scientific knowledge to real-life problems.
Students completing Science 20 in the first semester please complete units in this order: D, C, A, and B.
If you are ever concerned about anything with this course, either the content or the technology behind it, please call 780 864 1606 or send an email right away to joancoy@pwsd76.ab.ca. 
Students must have submitted all their assignments in the first two units before they write their midterms.
Students must have completed all their assignments before they write their final exam in this course.
We will analyze and investigate the cycling of matter and energy flow through the biosphere and ecosystems and the interdependence of society and the environment.
We will analyze ecosystems and ecological succession in the local area and describe the relationships and interactions among subsystems and components. We will also analyze and describe the adaptation of organisms to their environments, factors limiting natural populations, and evolutionary change in an ecological context. 
We will analyze the scientific evidence and explanations for geological phenomena that occurred long ago or that are taking place over a long period of time.
We will analyze and assess the evidence provided by the fossil record to indicate that the environment and life forms have changed over a period of 3.5 billion years.
We will analyze the evidence and assess the explanations for natural variations in Earth’s climate over the last two million years. 
In Chapter 1 you will look at the building blocks of matter and explore how they connect with each other. You will study how many of the methods developed by scientists to disassemble and reassemble basic parts of matter involve solutions. These methods are used to produce many of the consumer goods you use today.
In Chapter 2 you will learn how metals are mined, protected from corrosion, used to generate an electric current, and plated onto the surface of other metals. Throughout this chapter, your knowledge of valence electrons, solutions and bonding from Chapter 1 will be used to support your new learning.
In Chapter 3 you will examine carbon-based molecules that are the building blocks for materials made from petrochemicals. You will investigate the processes used to get these molecules, methods used to classify them, and reactions used to change them. 
We will describe one-dimensional motion of objects in terms of displacement, time, velocity and acceleration.
