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.
| Activities and text provide moderate coverage of the standard. |
Features that help student learning:
Many of the standards are addressed both in text and activities that complement each other. Many activities build on one another causing students to reflect on their learning and apply it to the next activity or text. Additional information clarifies the intent of the standard, often through relevant or engaging topics. Reading is often introduced after an activity so that students have a basis for building vocabulary and understanding. The standards that have the most content tend to be treated with the most depth.
Features that do not help student learning:
The focus on using a few chemicals and properties helps deepen understanding (e.g. salt, concentration, saturation, evaporation), but has the disadvantage of that it may limit generalizing to understand important principles (e.g., using physical and chemical properties to identify compounds, or distinguishing compounds and mixtures). About half the standards are addressed exclusively in the Science Stories, without associated activities.

|
| 1a During chemical reactions, the atoms in the reactants rearrange to form products with different properties. |
In-Depth |
|
| 1b Students know all matter is made of atoms, which may combine to form molecules. |
In-Depth |
|
| 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. |
Moderate |
|
| 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. |
Moderate |
|
| 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). |
Limited |
|
| 1h Students know living organisms and most materials are composed of just a few elements. |

|
| 1i Students know the common properties of salts, such as sodium chloride (NaCl). |
