    I just stumbled over your blog and wanted to tell you that I like the idea of seed guessing.
    I have no single idea what kind of seed this could be, but it looks really interesting and exotic. Will be back to check the solving 🙂

    Greetings from Germany,

    Stumbled across your blog last week. VERY nicely done. Hope in all the chaos I can remember to keep up with you. We are beginning our study of boats and ships, so yesterday we did a density lesson including your demonstrations with clay and then sodas. It was a big hit. Then I "fooled" my kids by adding salt to the water before they did the demonstrations for their dad.

    This reminds of the seed of some tree nut. Over a year ago we looked at a chart and I think there was a nut (maybe a chestnut) that made a pod like this. The seed guessing also reminds me of a book that my son enjoyed called, The Silver Balloon. I believe the author is Susan Bonners. Thanks for a great blog!

    (I was actually searching Google Image on the term "pumpkin leaf" because we have some mystery plants coming up from the spot where we buried our scraps last year. I was trying to differentiate pumpkin leaves from cantaloupe leaves. How lucky am I that it brought right to the page that was appropiate for our current studies!)

    I also have one of these ! It's got many names, Devil Pod, Bat Nut, Goat Head, Bull Nut& Buffalo Nut. It is the seed of Trapa bicornis, an aquatic Asian plant so 'Mr Google' tells me !

    I used to collect these on the Shores of the Caspian sea in northern Iran. Hard black seeds. I never new what plant they came from. But Caspian is is salty and bitter. I don't think they grew in that water.
