The lesson starts with a warm-up activity in which students think what each part of the word biometrics might refer to. Then, they read a definition of biometrics. Their task is to  complete the gaps with correct forms of words (e.g. distinction – distinctive, authentic – authenticate). Students also need to complete examples of biometric identifiers. Next, they discuss some questions related to the article they read at home and share their opinions on the use of biometrics. Finally, students look at a list of biometric technology applications and say which of them they find intrusive and why.
