Yes, you can see air. For example, one a cold night when you breathe-that's air that comes out, When it's a cold night and you pour cold liquid on the ground, you can see the air rise into a steam. You can also see the air you breathe when you breathe on a pane of glass or mirror. And as far as measuring it, well there's a website for that and it even gives you tables at the end. You can use if for a class experiment if you wanted to-it takes 3 people to do one experiment. Here's the link: chemistry.bd.psu.edu/aronne/Air%20S'05.pdf Hope this helps.

well this is a good question
you cant see air directly however you can see some effects of it...
wind - a fan can move the air particles and you can feel that
diffraction - when light goes though high and low pressures of air it will bend
viscosity - how does the air impede an objects progression though it... a ball vs a feather... how do they fall... is related to pressure
that is just a few ways you can measure it...
