Car project that uses piper, blocky and tethered car


My 7 year old daughter is loving her Piper Pi Kit. She loves blocky. Problem is there are not many projects that can be can be done without going out of blocky. Things my 7 year old cannot do at present. I’d love to do a tethered car with her but the only posted project requires 3D printing. There has to be more for the elementary school kids. Arent there?
