# The Standards

### Earth's Place in the Universe

#### Students who demonstrate understanding can:

Make observations at different times of year to relate the amount of daylight to the time of year. 1-ESS1-2

Clarification Statement and Assessment Boundary

Clarification Statement: Emphasis is on relative comparisons of the amount of daylight in the winter to the amount in the spring or fall.

Assessment Boundary: Assessment is limited to relative amounts of daylight, not quantifying the hours or time of daylight.

##### Science and Engineering Practices

Planning and Carrying Out Investigations

Planning and carrying out investigations to answer questions or test solutions to problems in K–2 builds on prior experiences and progresses to simple investigations, based on fair tests, which provide data to support explanations or design solutions.

##### Disciplinary Core Ideas

### Common Core State Standards Connections

ELA/Literacy
• W.1.7 - Participate in shared research and writing projects (e.g., explore a number of “how-to” books on a given topic and use them to write a sequence of instructions). (1-ESS1-2)
• W.1.8 - With guidance and support from adults, recall information from experiences or gather information from provided sources to answer a question. (1-ESS1-2)
Mathematics
• 1.MD.C.4 - Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another. (1-ESS1-2)
• 1.OA.A.1 - Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (1-ESS1-2)
• MP.2 - Reason abstractly and quantitatively. (1-ESS1-2)
• MP.4 - Model with mathematics. (1-ESS1-2)
• MP.5 - Use appropriate tools strategically. (1-ESS1-2)
