Mini Marsh Project

Our classroom received a mini marsh project from the Bay Area Restoration Council. Our teacher picked up the mini marsh from the RBG and brought it back to our class for us to work on Monday. We have had the mini marsh for a couple weeks now.

Snail Eggs

Freshwater snails are often hermaphrodites. In other words, they carry both sperm and eggs and can reproduce without the help of another snail. We think that's what happened with our snail.

We counted the egg sacs and we got 24, each snail egg sac has an average of 24 eggs inside so we did 24 x 24 and we got 576 so we have 576 snails depending on how many hatch.

An Update on the Mini Marsh and the snail babies

A shocking turn of events has happened after our whole class thought the baby snails were dead! Every time we have looked at the snails they have either been dead or inside the sacks. On Wednesday, May 24th, 2023 Avery made a shocking discovery that the baby snails are alive. Avery and Hannah plan to save the baby snails by separating the babies into a different tank. After lots of research we have decided that separating the babies is the best thing for the snails. We have been checking on the mini marsh and it has been starting to smell like rotten eggs, Tuesday jun 13. the babies have died on Monday jun 4 we discover that they were died.

we changed the water because it got so bad we did not see the snail and we thought it died but it was alive and we the babies are dead and w gave the snail some watermelon and its doing fine like before.
