Let's Eat Dirt (Not
Really) - What's In the Soil?

When gardeners prepare their soil for
planting season, they try to make sure it has a little bit of all the
"ingredients" that make a rich, fertile growing medium. So it's good to know
what they are.
You should never, ever eat soil, and
don't let your younger siblings eat it, either. But for this lesson in what
soil is made of, let's eat the things that REPRESENT the things that come
together and form dirt!
If you can think of more soil parts
and edible items that represent them, add them to the mix!
Into each student's cup, put:
Crushed Oreo wafers, representing
dark, rich compost.
Brown sugar can be sand.
Nerds candy = small bits of gravel.
Peanut butter = clay soil.
Chocolate pudding = silt.
Pretzel sticks (broken up) = small
Chopped chocolate chips = crushed
M&M's = microorganisms that help
with decomposition into good soil.
Gummy worms = bet you can guess what
