Soil Experiments

We have been taking some time to learn a little more about soil. We have gathered some samples (thanks to all of you) and have begun to take a closer look at soil, what it actually is and what it can do. We are learning so much as you can see in the pictures below.


Comparing Soil Colors
Is it brown, black, gray, red, greenish-gray, etc.?

Comparing Soil Textures
Is it soft, hard, sticky, clay-like, gritty, rocky, sandy, etc.?





Soil Drainage
Which soils allow water to drain through quickly?





Soil as a Filter
Is soil a filter? Will it clean water?
Ready?

Pouring in concentrated Kool-Aid
Hmm...Some samples did seem to "clean" the Kool-Aid out of the water.
Settling Soil
What are the parts of soil?
Today we shook jars of soil and water and then let them settle. They settled into layers. We could see silt, sand, clay, humus as the layers in our samples.



The settling has begun and will continue over the weekend.


Homework
No homework for the weekend. Enjoy some great books with your child.

IA
Our IA next week is PE. Please help your child remember to dress appropriately.
