    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.

    • Topic 1

      Unit D: Changes in Living Systems Trees

      Matter cycles and energy dissipates through the biosphere and its component ecosystems. The concept of an ecosystem is used to explain energy flow and nutrient recycling and to quantify large-scale and long-term processes. Students will study habitat destruction, ecological succession and changes to populations, focusing on the need to balance the interests of a growing human population with sustainable ecosystems.

      Unit C:  The Changing EarthPolar Bear 

      The history of our planet is one of change. There is evidence not only that Earth’s surface is changing but that this change has, in turn, dramatically impacted the climate and life forms on Earth over time. In this unit, students examine scientific evidence for natural causes of climate change, for changing life forms and for continual changes to the Earth’s surface.

      In this unit your project will be a presentation. This presentation could be used in a classroom and will examine the cycles of changes that have occurred to our Earth and how human activity has affected the cycle of change.

      Unit A: Chemical Change White Water Rafting in the Kootneys
      Chemical processes are all around us and contribute to almost all of the products we interact with each day. The plastic in your alarm clock, the computer you are at right now, your shoes, any substance that you added to your hair this morning, the boats in this picture, even the rocks in the picture have undergone chemical changes.

      In this unit you will investigate chemistry from the point of view of producing consumer goods. In all of these chemical transformations, we must evaluate the balance between human needs and environmental sustainability.

      Unit B: Changes in Motionskater
      Motion is an important aspect of our lives, and the understanding of the effects of force on motion has many technological applications. These applications can range from the design of safer roads and sports equipment to the investigation of traffic accidents. This unit will explain how motion can be describe in terms of displacement, time, velocity, acceleration, force, momentum and mechanical energy.

      This unit will focus on a project on accident analysis. You will work on the project as you progress through the unit. When the unit is done the project should be complete and ready to hand in.
      Let's begin by watching a video from your Science Text CD. It is called "Career Investigation: Accident Reconstruction"
