Digging for soil

In science, we have been learning about rocks and soil.  We learned that soil is made of two things - rocks and humus.  We know a lot about rocks already and so we learned that humus is decayed Earth material, such as plants or animals.

Last week we observed soil that we made in the classroom.  We noticed that the soil was made of different sized rocks - sand, clay, pebbles, and gravel - as well as humus.  When we added water to our vials of soil we saw that some of the humus floated and some of it did not!

Today we walked to the park and collected soil from a variety of places.  We then began comparing the soil that we made in the classroom to the soil we found at the park.  Even though all of the soil was from the same park, it still looked different based on where we found it.

We will continue our study of soil for the next few weeks - and see how it affects plants in the near future as well!
