some great authentic projects that technology could be integrated into as cognitive tools. For example: video or PowerPoint presentations documenting the building process and reporting on concepts learnt or blogging for reflecting and articulating the processes and concepts used to create the end products.
another potential resource - for students to present their work. Note sure about privacy or most suitable age group - you will have to check these features :)
I suggest making games would be more authentic if you get students to make the quizzes and games to present their learning about your topic (rather the teacher creating them)
