You don’t necessarily need the same teacher for the different subjects. Just coordination among the teachers. In high school we did a solar hot dog cooker project. In my Algebra 2 class, we determined the right conic to use for the cross-sectional shape of the reflector. In my physics class we calculated the energy coming in from the sun at various times of the day for our latitude. In my drafting class we produced blueprints for the cooker. And over in wood shop, they built the cooker using the designs we drew (which were dependent on the math from Algebra class), and using the materials selected by the physics class. Then one day we all went outside and cooked our dogs. This was a one-off thing of course. My school wasn’t structured to completely integrate all the subjects all the time. But it was valuable in teaching mushy things like project coordination and management. It was kind of like a group project, except each member of the “group” was more like a cog in the supply chain :)
