An idea for a lesson would be to show students the changes that have occurred with the identification systems used on farms. The old technology included fire and freeze branding, ear notches. The development of plastics allowed for flexible tags that could carry some numbers and letters.
Modern systems now include an RFID tag that can be read with a digital reader that is hand held or enclosed in a fence panel.
The development of this technology has important benefits for produces, who can use the electronic id to link to their on farm database.
