Standard: Show Content Tip
1a During chemical reactions, the atoms in the reactants rearrange to form products with different properties.
Holistic Rating: Moderate coverage of this standard.
| Pages C20-C27 provide moderate coverage of this standard. (NOTE: the Teacher's Edition we used does not cite pages C22-C27 for this standard.) |
Aspects that help student learning:
Comparing rust and iron on page C22 provides a well-developed example showing that the product of a chemical reaction has different physical and chemical properties than the starting reactants.
Activities on pages C33, C56 and C57 give students experiences with chemical reactions, and the text provides many examples of chemical reactions. Graphics on pages C20-C27 illustrate changes that happen in chemical reactions. The California Science Framework recommends having students identify the reactants and products when observing and discussing chemical reactions.
Aspects that do not help student learning:
The text does not describe chemical reactions in terms of atoms rearranging. As described in the CONTENT TIP for this standard, students can model the electrolysis reaction (splitting of water into hydrogen and oxygen) to help teach this concept which can be difficult for fifth grade students.
Teacher's Edition that we used cited these pages as addressing this standard, but we did not find a significant correlation:
C30-C31, C46-C47, C55
