theme for our contest this year is fruit
 

I am the Ag Teacher at Cody-Kilgore HS in Cody NE. I am in charge of the sensing devices part of
our district Ag Mechanics contest. The theme for our contest this year is fruit, nut and vegetable
production. What I am looking for is a simple diagram or flyer containing some sensing devices that
the students can use for a problem solving activity. If anyone has any suggestions or can help please
do so. My e-mail address is [email protected] Thank you!!

I would like that information too. I have been through dozens of pH and ppm meter pens in the last
few years and at about $100. per it gets expensive.
