is a major component of cells. It has several properties that are important in biology. In particular, water: is a metabolite is a solvent has a high heat capacity has a latent heat of vaporisation has strong cohesion between molecules. 0.2 weeks Describe the properties that are important in water. Explain the properties of water linked to the polar nature of the molecule. Explain the significance of these properties to living organisms and processes. Learning activities: teacher explanation of the polar nature of water molecules practical investigation activity circus to include: surface tension – count how many drops of water that can balance on a penny. Repeat with soapy water and oil cohesion – capillary tubing with dyed water solvent – add salt to water and oil and compare the relative amounts of how much can dissolve specific heat capacity – compare the temperature rise of water and vegetable oil put on hot plates for the same time latent heat of vaporisation – model the effect of sweating on heat loss from boiling tubes (using boiling tubes wrapped in wet and dry paper towels) teacher explanation of the significance of water to all life on Earth in each of the Past exam paper material: BYB1 – June 2008 Q4
