We developed a popular class called "Toys That Move: The Physics in the Toy Box," which lets kids examine a wide range of toys and figure out the science and technology behind them. We start with really simple toys: balls, friction toys like Matchbox cars. Then we move to gears and springs, and let the kids take them apart to see how these all inter-connect. We also do one session on batteries and electricity, and then a final session on radio-controlled toys. Almost everything we use in the class can be made or bought very inexpensively, and since we aim it toward younger children (7-10 year olds), we also can use assistants who needn't have PhDs. in physics in order to help. If you're interested, let me know and I can give more specifics.
