We’ll kick off our new unit on STRUCTURES by looking at the structure of the the atom.  YOU KNOW THIS STUFF ALREADY so the first part will be a recap, then we’ll go beyond the material you covered in Grade 8.

Here’s the presentation we will use in class: KS4 The atom

And here are some practice worksheets to see if you have understood the concepts.  DO THEM! struc of atoms1   basic at struc

This is a useful resource to help you get up to speed with these ideas.
