[IAEP] It's Time to Sign Up For Sensors!

[Yama Ploskonka]

I must have missed it if there was any comment on it, but Claudia Urrea 
has been working on sensors for many years already -
She was kind enough to show me a box with several ready to use sensors 
the time I was in OLPC headquarters in Boston, like 3 years ago?

As the head of the education dept of OLPC (unsure if that is still the 
case or the actual title) no doubt she can contribute detailed and 
proven lesson plans that teachers have used successfully, full reports 
on the use of sensors, in the field, in OLPC deployments.
