Present a demonstration to fellow students outlining why ionic compounds conduct electricity when molten or in aqueous solution.

Preparation time:

1 lesson to research material and plan roles to be undertaken by group….. cameras…. action….. roll…. take 1.

This is an opportunity for you to demonstrate your learning…….it also shows me where I need to do better. Sodium ions don’t get discharged from aqueous solution…..apologies for any confusion I may have caused here!

Your mission should you chose to accept it is explain changes in the properties of clay as it is allowed to dry, bisc fired then given a final firing and glazing.
