Grade School the Second Time Around-The Atom

This semester in fourth grade science we are discussing renewable and non renewable energy sources. Because nuclear power falls under this topic, we have also been discussing atoms and their place in the universe. Last week, in order to provide the students with an idea of how really, really, really tiny an atom is, the teacher showed them a video that explained it like this…

Picture a grapefruit. Now let’s consider the nitrogen atoms in that grapefruit (there are lots of other types of atoms but for now we will just focus on that one.) Lets pretend that we can take those nitrogen atoms and blow each one up to the size of a blueberry. In order to accommodate those blueberry sized atoms the grapefruit would now become roughly the size of the planet Earth. 😳

But wait! There’s more!

Continuing along that line… if we wanted to see just how small the nucleus inside each atom is we would have to blow that blueberry up to be the size of a football stadium. Even then, the nuclei would only be the size of a small marble!

POW!!! Mind blown!

I can tell you the students were certainly impressed. It was a learning experience for me as too!
