This 29-slide Powerpoint presentation covers 'Topic 2.2 - Water' in the 2016 IB Biology curriculum. Each slide includes the specific learning objective as well as key vocabulary that students should note. The topic has been divided into 3 sections:
A - Hydrogen Bonds
B - Properties of Water
C - Blood Transport
The presentation itself contains minimal information as it is intended to be used with teacher guidance. They are also formatted to be visually pleasing and to print well for handouts or revision. Please see the preview file for an idea of the slide aesthetic and level of detail.
As always, please let me know if you have any suggestions for improvements. These are always a work in progress!
U1: Water molecules are polar and hydrogen bonds form between them.
U2: Hydrogen bonding and dipolarity explain the cohesive, adhesive, thermal and solvent properties of water.
U3: Substances can be hydrophilic or hydrophobic.
A1: Comparison of the thermal properties of water with those of methane.
A2: Use of water as a coolant in sweat.
A3: Modes of transport of glucose, amino acids, cholesterol, fats, oxygen and sodium chloride in blood in relation to their solubility in water.
