Below is the link to a website that gives a comprehensive explanation about the inquiry-based strategy for lesson planning. The interactive demonstrative would be like guiding students thru practice, so you would demonstrate but have them also ask questions and practice or participate in what you are doing (e.g., ask them to come up and write or use the White board). One strategy to use in inquiry is to give students a topic to debate and have them research it in defending the8ir position (for or against topic). Attached is a recent conference paper presented at a Scholarship of Teaching and Learning conference in the U.S. 2015 that can help to demonstrate how the debate is set-up and conducted. I hope this is helpful to your question.
Many thanks,
