Fifth grade archaeologists wanted to know: In which environment will "artifacts" decompose least? most? Which artifacts would decompose? Jars were filled with sand, moist compost, moist clay, and rain water. Tomatoes, wood,cotton cloth, bone, iron clip, plastic straw, and paper were the artifacts. Placed in jars in November, here are some images of the results.
After 3 and 1/2 months these tomato sprouts appeared!
And these sprouts which appeared a few weeks earlier are drying out...
Paper finally break down.
Cotton cloth rotting away.
Damp clay is breaking down the bone.
Sand dried tomato!
Microbes in compost are doing their thing.
Leaf just a skeleton...
Dry as a bone.
Fabric freshener?
