Awesome initiative. If I had to teach physics on a shoestring budget I'd go back in time to the 1700's or so, take the methods and principles as discovered then and teach science as a method instead of physics specifically.
Use physics as an illustration of what goes in to good science with the relatively simple devices of that age and you're laying the foundation for more education later on.
For example, your '4', heat: I'd use a simplified Stirling engine for that, it wouldn't take more than a bunch of clothes hangers and tin cans to make a working heat engine, which gives you all the hooks you need to go from Boyle to Carnot.
