Biosphere Update--Day 18

Biosphere Day 18

We are following along with The Magnifying Glass on their Make-along project:  microbe biosphere .  Our biosphere is starting to get very colorful.  The dirt where we live is reddish orange, and ours is starting to show some black spots all around. Though it's hard to tell from my photo, there is a layer of clear water on top of the mud, and a fine layer of sediment on top of the water.  A darker layer has also formed around the top edge of the mud layer.

Wow!! Yours is really coming along.

As long as you leave it alone (don't move it / shake it) you will see even more changes in the coming weeks. This is just the beginning!
