Science Curriculum
2nd Grade
|
Course Purpose: |
Second Grade students will develop and use models to explain similarities and differences among processes and objects. |
Outcomes and Components:
| SC.2.1 | Students will analyze various materials for their observable properties to evaluate the purposes for which they are best suited. Students will construct evidence-based arguments that some chemical reactions can be reversed while others cannot. | ||

Standard(s) |
| SC.2.1.1 | Classify and describe matter as a solid or liquid based on its observable properties. | 2-PS1-1 | |
| SC.2.1.2 | Characterize various types of materials by their observable properties (texture, color, smell). | 2-PS1-1 | |
| SC.2.1.3 |

2-PS1-1 | |
| SC.2.1.4 | Evaluate data gathered from observations and investigations of which properties of materials are best suited for different purposes. | 2-PS1-2 | |
| SC.2.1.5 | Use observations to justify how an object made up of small parts can be disassembled and made into a new object. | 2-PS1-3 | |
| SC.2.1.6 | Observe that matter can undergo physical and chemical changes. | 2-PS1-4 | |
| SC.2.1.7 | Construct an evidence-based argument that some changes are reversible and some are not. | 2-PS1-4 | |
