Just found this link (it is in German but Google will help translate it).
Thank you.
Quite a short list though for Zurich 😉
This place is a bit outside of Zürich and doesn't have a good public transportation option, but Jucker Farm is great for kids. They have a petting zoo, and in the fall they have giant squash sculptures (it is way cooler than it sounds!). During the summer, you can pick your own cherries, watch them press apples into juice, go down to the lake for a dip, and generally run around...my kids love it.
