@Vanessa L here is a video of my mini worm tower as u asked for

Hi all! Sorry I've been MIA since Sep as work is kicking my behind 😆 However, I am back with a question I am thinking of starting a worm farm with my students as part of our science unit. However, I have two problems: 1) I need to make it small as I don't have a lot of space. 2) I also don't have a lot of worms anyway as I only bought 1/4 lb for my farm. Unfortunately I cannot buy more, as we were not given any budget to buy anything outside of Staples, and last I checked, Staples did not sell worms 😂 I've also already spent over $300 of my own money for my classroom so I would prefer not to spend more. I don't mind taking some worms out of my personal farm for my students but I also don't want to remove too many worms and slow its progress. SOO my questions are: What size bin would you recommend for a classroom? And what would be the minimum number of worms that I would need in order for our bin to be able to see progress or at least some kind of movement within one or two months? Worst case, I just don't do a worm farm and maybe wait until my worm farm is bigger to do it with a different class in the future. Thank you experts!!!

Enjoy your Holiday Weekend and the Great Weather most areas are having. A lot better than the Cool Torrential Rains, Hail, Snow, and Tornado Advisories we have had in many areas the past few days !

Maybe it's because I only have one worm bin and it's my first, but anyone else feel the need to obsessively check in on their worm bin just to see what's going on 😆 I feel like after all the excitement of setting up, experimenting with proportions, and The Great Fly War, now that things have settled, I'm feeling like I need to find something to do with it 😆 Is this how you have all ended up with a million bins? 🤣😜

When do you decide to sift castings? How can you tell if they're worm castings or just coffee grounds?
