# The Standards

### Earth and Human Activity

#### Students who demonstrate understanding can:

Ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century. MS-ESS3-5

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of factors include human activities (such as fossil fuel combustion, cement production, and agricultural activity) and natural processes (such as changes in incoming solar radiation or volcanic activity). Examples of evidence can include tables, graphs, and maps of global and regional temperatures, atmospheric levels of gases such as carbon dioxide and methane, and the rates of human activities. Emphasis is on the major role that human activities play in causing the rise in global temperatures.

Assessment Boundary: none

##### Science and Engineering Practices

Asking questions and defining problems in grades 6–8 builds from grades K–5 experiences and progresses to specifying relationships between variables and clarifying arguments and models.

##### Crosscutting Concepts

Stability and Change

### Common Core State Standards Connections

ELA/Literacy
• RST.6-8.1 - Cite specific textual evidence to support analysis of science and technical texts. (MS-ESS3-5)
Mathematics
• 6.EE.B.6 - Use variables to represent numbers and write expressions when solving a real-world or mathematical problem; understand that a variable can represent an unknown number, or, depending on the purpose at hand, any number in a specified set. (MS-ESS3-5)
• 7.EE.B.4 - Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning about the quantities. (MS-ESS3-5)
• MP.2 - Reason abstractly and quantitatively. (MS-ESS3-5)
