Peer feedback to initiate a discussion after an oral presentation

Description:

The students are working together in a group on assignments existing of calculations and questions. There are 2 weeks allocated to this. The students have opportunity to work on this in-class with supervision of the teacher on 3 days and are also expected to work on the project out-of-class. On the fourth day one group will present the work and a discussion/feedback will follow afterwards. Lastly, the students will correct their report before handing it in. There are 4 loops of the STREAM model in these 2 weeks. I would like to improve the discussion on meeting day 4 by using Padlet. The problem I would like to engage the students more in the discussion. In my experience, the teacher usually opens the discussion by asking the other students if they have comments or questions. Often, there are very few comments and it is mainly the teacher who asks the questions. I would like to try to get the students to be more engaged (they should be the ones asking most questions) by giving them a few questions to consider before the presentation starts (examples below). During the presentation, the students should pay attention to these questions and make short notes using Padlet. After the presentation we will discuss the points from Padlet.

Questions to consider:
Are there any calculations or answers to questions presented which differ from yours?
Are there any points to which you would like to have more explanation?
