Earth and Space Science
No resources have been tagged as aligned with this standard.
Rocks have specific characteristics that allow them to be sorted and compared. Rocks form in different ways. Air and water are also nonliving resources.
Rock classification is not the focus for this grade level; this is found in grade 6. At this grade, the observable characteristics of rocks can be used to sort or compare, rather than formal classification.
Soil is composed of pieces of rock, organic material, water and air and has characteristics that can be measured and observed. Use the term “soil”, not “dirt”. Dirt and soils are not synonymous.
