​What Are We Learning Today (WALT)

• By the end of this lesson you will be able to:

  • use patterns to predict the properties of elements. 

  • compare patterns in properties in the groups and periods of the Periodic Table.

  You will be working scientifically to:

  • apply maths and calculate results.
