I love using LEGO to explain the tricky concepts both in my videos and the lessons I teach. The bricks are simple but they are a great way to illustrate complex ideas in an easy way.
Just a few bricks can be used to demonstrate ions, isotopes, ionising radiation, the quark structure of baryons, beta minus and beta plus decay.

I first saw LEGO used to help explain particle physics in material produced by Queen Mary's University (available here). I then developed this with futher bricks to make photons, quarks and the entire standard model. Like any model there are some limitations, however, I find that LEGO does help students to visualise some of the more difficult parts of this course.
You can buy individual bricks in any colour and quantity you need from the LEGO Pick a Brick website.
The bricks that I used are:
2x2 Brick - Yellow
2x2 Brick - Red
1x1 Brick - Grey
1x1 Plate - Grey
2x2 Plate - Yellow
2x2 Plate - Red
