# The Standards

### Waves and Their Applications in Technologies for Information Transfer

#### Students who demonstrate understanding can:

Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance. 1-PS4-4

Clarification Statement and Assessment Boundary

Clarification Statement: Examples of devices could include a light source to send signals, paper cup and string “telephones,” and a pattern of drum beats.

Assessment Boundary: Assessment does not include technological details for how communication devices work.

##### Science and Engineering Practices

Constructing Explanations and Designing Solutions

Constructing explanations and designing solutions in K–2 builds on prior experiences and progresses to the use of evidence and ideas in constructing evidence-based accounts of natural phenomenon and designing solutions.

##### Disciplinary Core Ideas

PS4.CInformation Technologies and Instrumentation

##### Crosscutting Concepts
###### Connections to Engineering, Technology, and Applications of Science

Influence of Science, Engineering, and Technology on Society and the Natural World

### 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-PS4-4)
Mathematics
• 1.MD.A.1 - Order three objects by length; compare the lengths of two objects indirectly by using a third object. (1-PS4-4)
• 1.MD.A.2 - Express the length of an object as a whole number of length units, by layering multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps. (1-PS4-4)
• MP.5 - Use appropriate tools strategically. (1-PS4-4)
