Unit 2
Area of Study One
Living things on earth have evolved to use water and the gases of the atmosphere in the chemical reactions that sustain them. Water is used by both plants and animals to to carry out their energy-producing reactions, dissolve their nutrients and transport their wastes. The atmosphere supplies life-giving gases, provides temperature that sustains life, and gives protection from harmful radiation. Appropriate chemical concepts are introduced and students are encouraged to evaluate the environmental impact of human activity on the biosphere. All areas of study in this Unit involve the design and performance of experiments, including the generation, collection and evaluation of experimental data.
This Area of Study covers the the role of water in maintaining life, acids and bases, the pH scale, redox chemistry and stoichiometric calculations.
Area of Study Two
Living things on earth have evolved to use water and the gases of the atmosphere in the chemical reactions that sustain them. The atmosphere supplies life-giving gases, provides temperature that sustains life, and gives protection from harmful radiation. Appropriate chemical concepts are introduced and students are encouraged to evaluate the environmental impact of human activity on the biosphere. Both Areas of Study in this Unit involve the design and performance of experiments, including the generation, collection and evaluation of experimental data.
This Area of Study looks at the role of the atmosphere in sustaining life on Earth. Acid rain, the Greenhouse Effect, carbon and nitrogen cycles, kinetic molecular theory and the Gas Laws are all considered.
