You would have found, I’d imagine, a set of posters students completed during a recent geography unit, or drawings that students created during their visual arts class.

For example, while I taught elementary school students in America, we sprouted potatoes in diferent parts of the classroom for a unit on the scientifc method, cared for tadpoles for a unit on the frog life cycle, and (under
microscopes) studied pond water, which we retrieved from a nearby reservoir.

It’s more like a guiding principle that teachers can seek to apply every day in their classrooms, not just at the beginning of a lesson or a unit.

What matters most is that teachers carve out time before launching a unit or a project, to discuss the direction of the learning with their students, and then draw upon that discussion to shape the unit or project

Finnish comprehensive schools (grade one to grade nine) develop and offer one interdisciplinary unit of study, which is of particular interest to the children, per school year for all students.
