New York Grade 1 Science

Design a signal another person can understand

Design and test a classroom signal in New York Grade 1 science, explain how its code works, and find selected state references, lessons, and independent quizzes.

The current NYSED science page links the New York State P-12 Science Learning Standards. These state standards include expectations and supporting information that differ from the original NGSS. This page’s selected reference was checked in the actual New York document, including its clarifications, boundaries, practices, core ideas, and crosscutting concepts. This activity selects a Grade 1 expectation. It is one part of a science course, not a complete curriculum.

The official introduction (PDF) explains that the state defines performance expectations while districts and teachers make instructional and sequencing decisions. Middle-school expectations are organized by topic for a Grades 6–8 band, rather than assigned to each of those grades separately. Read the complete state document alongside the school’s science course. This original activity is a focused starting point, not a complete curriculum crosswalk.

Design a signal another person can understand

A class needs to send either “ready” or “wait” across a quiet room without calling out. An adult supplies a small flashlight and paper cards with an agreed code: two short flashes mean ready; one long flash means wait. Design a simple way to aim the light where a partner can see it without pointing into anyone’s eyes. Test the two messages from the same position. Record what message was sent and what the partner understood.

Explain the evidence or model

The flashlight supplies a visible signal, but the pattern carries the message only when sender and receiver agree what it means. A successful design must let the receiver see enough of the light and distinguish the patterns. Compare the intended message with the partner’s reported message rather than declaring success because the light turned on. If a card blocks the beam or the two short flashes merge into one, revise the position or timing and retest. A child can draw the light source, receiver, and pattern beside a short record. This activity supplies a design problem and test plan, not a completed set of observations; the class should keep its own results.

What to check in the explanation

A brighter light does not automatically create a clearer code. The receiver needs an agreed meaning and a detectable pattern. Do not claim the system works around an opaque obstacle without testing the actual arrangement. The task models communication over a classroom distance and does not explain the technological workings of every communication device.

Plan the next activity

1. Agree on distinct message patterns.
2. Build a simple light-signaling arrangement and test both messages.
3. Compare sent and understood messages, then revise one feature.

Try the same code from another teacher-chosen position. Explain what changed in the arrangement, and retain the original pattern definitions. Compare when a light signal would be useful and when a teacher-approved sound pattern might work better.
