Design and build a device that uses sound to communicate over a distance.
Aligned tasks under 2.8C balance fluency and reasoning so students can explain decisions about Design device using sound.
TEKS 2.8C bridges prior learning and next steps in Science, keeping Design device using sound coherent across the year.
Start with concrete or familiar examples, connect to prior knowledge, model a clear process, and provide checks for understanding aligned to 2.8C.
Standard 2.8C describes the essential skills and understandings for Design device using sound in Grade 2. It clarifies the learning outcomes and what successful work looks like.
It lays groundwork for the next grade by deepening accuracy and flexibility with Design device using sound, so students can tackle more complex problems later.
Use short exit tickets and tasks where students explain decisions, show multiple representations, or justify answers—directly aligned to 2.8C.
