This pack is a supporting vocabulary fit to NGSS 1-PS4-4 (Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance), because the cards help students name light and sound signals, describe how those signals send a message, and connect tools such as flashlights, drums, sirens, and phones to communicating over a distance. This is vocabulary practice with picture, definition, coloring, and write-the-name pages, not a complete 1-PS4-4 investigation. The PDF does not print a grade or standard code. Best-fit tag is Grade 1, matching NGSS 1-PS4-4 light-and-sound-signal vocabulary.
