Concept Statement: Show Concept Overview
1 Elements and their combinations account for all the varied types of matter in the world.
Over-All Rating: Moderate coverage of this concept.
 |
Text includes and highlights extraneous terms and concepts that are in neither the science standards nor the science framework for this grade. Examples include density (pages C13-C15), radioactivity (pages C76-C77), and pH (pages C82-C85).
This set of physical science standards should lead students to understand a major idea in science, that the millions of different kinds of things in our world are made from just 92 naturally occurring elements, and that a small number of the elements account for the vast majority of things in our world (see Standard 1h). |
Features that help student learning:
Some of the standards are covered in-depth. Text has many useful illustrations and diagrams.
Features that do not help student learning:
Introduction of difficult concepts (e.g., density, radioactivity, and pH) makes it harder to explain the concepts and terms that should be the direct focus of the standards at this grade level.
Ratings for Standards - Houghton Mifflin:
| 1 Elements and their combinations account for all the varied types of matter in the world. |
Moderate |
|
| 1a During chemical reactions, the atoms in the reactants rearrange to form products with different properties. |
Moderate |
|
| 1b Students know all matter is made of atoms, which may combine to form molecules. |
Moderate |
|
| 1c Students know metals have properties in common, such as high electrical and thermal conductivity. Some metals, such as aluminum (Al), iron (Fe), nickel (Ni), copper (Cu), silver (Ag), and gold (Au), are pure elements; others, such as steel and brass, are composed of a combination of elemental metals. |
Moderate |
|
| 1d Students know that each element is made of one kind of atom and that the elements are organized in the periodic table by their chemical properties. |
In-Depth |
|
| 1e Students know scientists have developed instruments that can create discrete images of atoms and molecules that show that the atoms and molecules often occur in well-ordered arrays. |
Limited |
|
| 1f Students know differences in chemical and physical properties of substances are used to separate mixtures and identify compounds. |
Moderate |
|
| 1g Students know properties of solid, liquid, and gaseous substances, such as sugar (C6H12O6), water (H2O), helium (He), oxygen (O2), nitrogen (N2), and carbon dioxide (CO2). |
Moderate |
|
| 1h Students know living organisms and most materials are composed of just a few elements. |
Moderate |
|
| 1i Students know the common properties of salts, such as sodium chloride (NaCl). |
