examine the factors effecting solubility.

Bonding

Uses a “sketchpad” to assist construction of bonding diagrams.

Illustrates covalent and ionic bonding.

Explains why elements only combine with certain other elements and in set ratios.

Explores the bonding of complex molecules.

Diffusion

Using animation this software illustrates diffusion of liquids and gases.

Demonstrates how the particle model of gases and liquids explains diffusion.

Demonstrates evaporation of liquids in vacuum and gas.

Osmosis

This software simulates the classic potato experiment. Animations demonstrate osmosis at both the cellular and molecular level. You'll use it to:

Describe what happens in the experiment and explain why

Investigate what happens when you change the concentration of the solution surrounding the potato and explain why

Show how cells become turgid or plasmolysed

Practise investigations with less hassle and no washing up

Compare what happens in the real experiment to the simulation
