We have been thinking about examples of Information technology in the world around us. We discussed how IT is now everywhere, and can save us time and make out life easier. We found out how a shopping till works in conjunction with a barcode scanner, and then pretended that we were the shopping tills.
One person was the customer and chose 2-4 products.
The next person 'scanned' the barcodes and found out what each item was.
The final person found out how much each item cost and created a receipt.
