Water: The Highway of Life
Shows how the ability of water to dissolve substances makes it the primary system of transport in living organisms. The process of diffusion is described and a lab performed to show the rate of diffusion in gelatin.
-
Water Through the Ecosystem
Examines how transpiration affects climate. Explores the properties of semi-permeable membranes, and relates these to living cells. Discusses how plants adapt to climate and the effect of large bodies of water on climate patterns.
-
Weather Systems
Reveals how the meeting of high and low pressure systems causes unstable weather conditions. Discusses how global conditions affect weather, how data is collected for weather forecasts, and how storm activity can be predicted.
-
Harnessing Energy
Investigates several energy-transfer situations that harness energy: wind power, the transfer of potential to kinetic energy of water in hydro-electric production, and the use of fossil fuels to produce steam.
-
Safety Matters
Investigates the hazards associated with the handling and disposing of chemicals. Introduces WHMIS labels and Material Safety Data Sheets for common lab chemicals. Explains universal naming systems and how to write word and chemical equations.
-
Discovering the Elements
Conducts experiments to establish the physical and chemical properties of a number of representative elements. These elements are then grouped logically, first into metals and non-metals, then into groups based on observation of reactions.
