Hello, I’m searching for an old science show that my teachers would put on in primary school. The show was very old-fashioned, maybe filmed in 80s-90s? I remember the show had a black and white logo that would split apart and then clip back into place during transitions. (I think it was a black circle inside a diamond shape but I might be wrong).

I remember they did an episode on hydroponics, and I think there was also a subplot of a female character in a robotic-submarine like setting and a bunch of characters we met during the episode would recount what we had learned, but I’m not sure if it’s the same show. Thank you!
