Standard:
1h Students know living organisms and most materials are composed of just a few elements.
Holistic Rating: Limited coverage of this standard.
Text provides limited coverage of this standard on pages C36-C37 and C42-C47. The clearest statement is in a paragraph on page C42 (not cited in the Teacher's Edition we used), but the treatment is limited for a concept of this importance.
This standard teaches a major idea in science, that the millions of different kinds of things in our world are made from just 92 naturally occurring elements. Even among the 92, most of the elements are relatively rare. A small number of the elements account for the vast majority of things in our world. The California Science Framework (page 69) states this important concept very clearly: ". . . living organisms are mostly composed of the elements carbon, oxygen, hydrogen, nitrogen, sulfur, and phosphorous. The number of types of atoms used as 'building blocks' is relatively small. The way in which atoms are organized into molecules provides variety."

Aspects that do not help student learning:
Text does not clearly explain or develop the big idea that just a few elements combine to make all the varied types of matter in the world.
Teacher's Edition that we used cited these pages as addressing this standard, but we did not find a significant correlation:
C38-C39
