We’re doing a test on fluid dynamics today (students have to set up an
experiment illustrating differences and silarities between
Archimedes’, Pascal’s and Bernoulli’s Principles).

They are allowed to use their books, notes and each other for info as
long as the communication is non-verbal.

I have my Google Voice inbox up as a backchannel stream of texted
questions being projected.

Lots of texting and learning going on.

Awesome.
