C3.5 covalent bonding - foundation
aimed at a lower ability class
Starter Activity
Mark homework
Main –
Think pair share – spot the difference between ionic and covalent bonding. Then write down definition of covalent bonding
Watch video, only watch until 2 minutes. Answer questions whilst video is going. Goo through and green pen answers after
Go through the two examples on the board and show what happens
Students then have a go at completing their worksheet to show covalent bonds
Extension: decide if the compounds are ionic or covalent and explain how they know
Plenary
Plenary, fill in the gaps and go over answers

C3.4 Giant ionic structures - foundation
aimed at a lower ability class
Starter Activity
Using previous knowledge make predictions about ionic compounds
Main –
Go through and discuss giant ionic lattices
Students move around the room to find the information sheet to find out if there prediction was correct or not and why
Practical with a dissolved ionic compound to show it can conduct electricity. Make sure say that molten ionic compounds too and what a molten ionic compound is
