How much space is in an atom and why is nothing actually “solid”?

Teacher’s domain is a great place to go for resources. You can sign up for free in order to access hundreds of very high multimedia clips and collections covering Science, Engineering and Maths, etc. It is biased to the USA - but the quality of the content means it is suitable for use almost anywhere.
So just how much space is inside an atom? Here is a clip explaining it:

It reminds me of lessons helping children understand the scale of the solar system using peas, fruit and footballs! What is so amazing is that that concept of vast spaces is also found at a subatomic level and that there is no such thing as a “solid” material - only interacting electomagnetic fields (like sub atomic magnets repelling each other) makes it seem that way… Mind boggling!
In addition to the media clips that can be viewed online and in some cases downloaded, there are supporting “discussion questions” that are great for stimulating deep ideas for using your Promethean Activboard or Expression technology and State Standards mapping to help in your planning. You will also find lesson plans and Professional Development material that helps link the media to good teaching practice.
Amazing.
