The bottom of the ocean was suppose to be made from various kid-made stuff but hey, we had real sand, coral and all sorts of ocean things to use-so we went for the real look. I just took clear packing tape, stuck two pieces together and then taped it on the sides and bottom of the box. This created a lip to keep the sand from spilling out and all over.
I guess as we move through each unit of study we will add various creatures to this. Sounds like fun and I will post as we go. Oh and don't you know, as soon as this was all set up-we had our first residence arrive (who will not stay) to await the addition of new creatures.
LOL....oh Sponge Bob...this isn't Bikini Bottom.
