MYP Design: UN Global Goals Prototypes

I am going to be starting off my Grade 8 students with a UN Global Goals prototype unit. The idea is that they choose a UN Global Goal they want to focus on, and they make a simple prototype, out of paper, card, tape, etc. They will then do a 'speed sharing' activity (similar to speed dating), where they can share their prototype with their peers.
Throughout the unit they will produce work for every strand in their process journal. After they have completed each criterion, they will select key pieces of information and will create a 'one pager' for their summative assessment. This will have key quotes, facts, words, as well as illustrations to add further meaning. I was inspired by the 'one-pager' episode on the Cult of Pedagogy podcast. Also design demands a lot of time, effort and work from our students, and I wanted to minimise that stress, by trying out a one pager as a solution.
Here is a link to the google slide - it has everything you need to run this unit yourself!

We have moved towards having an online portfolio, where students show their work for all subjects, as well as extra-curricular and advisory/core work. At the end of every unit I will have reflection tasks and will give students time to add to their portfolio. I'm asking them to put the four one-pagers (summative for each criterion), as well as their answers to our inquiry questions. In our final reflection I also ask students what we can do next with our ideas, which will hopefully lead to some action.

Let me know if you use this and what results you get. Let me know if you have questions or suggestions.
(Also this is based on the UN Global Goal Challenge activity I made - you can use this if you want to do a mini version of this product, or you want to use this in another subject or non-MYP classroom).
