Hello,
I suggest that you start by reading this article :
https://www.iotforall.com/8-helpful-everyday-examples-of-artificial-intelligence
You may start by explaining what is Artificial Intelligence (AI) without going into details such as Machine Learning or PNL but mainly explain the difference between traditional computers (manage to do repetitive tasks that the software developper has implemented in the program) and AI that enables machines learn and acquire new competencies by themselves.
After that I suggest that you give few examples about AI and how it can help people do better things: smart cars, medical diagnosis, predict natural disasters like hurricanes, earthquakes and tsunamis, smart robots to perform difficult or dangerous tasks…
To conclude you can share your own experience with AI.
I hope this can help!
