Standard:
1h Students know living organisms and most materials are composed of just a few elements.
Holistic Rating: Moderate coverage of this standard.
Pages C32-C39 provide necessary background. Pages C40-C41 (especially the last two sentences on page C40) provide moderate coverage of this standard.
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. Pages C89-C90 does not sufficiently emphasize the main idea of how few elements there are in living things, and this concept is overshadowed by the complexity of the molecules shown and the newly introduced concept of polymers and plastics.
