Mississippi Science P.1.6B.2
The Standard
- P.1.6B
- Students will demonstrate an understanding of sound.
Create a device that uses light and/or sound to communicate over a distance (e.g., signal lamp with a flashlight). Use an engineering design process to define the problem, design, construct, evaluate, and improve the device. *

What This Standard Means
What Students Need to Do
- Students choose a message to send across the room. They plan and build a light or sound signal, test it with a partner, then change it and test again.
What Mastery Looks Like
- A student sketches a plan and builds a signal with an agreed meaning. A partner understands it from across the room, or the student makes a change and retests it.
Common Misconceptions
- Students may think a flash or noise has an obvious meaning without agreeing on a signal first. They may also think someone can see a light signal when the flashlight points away from them.
How to Assess It
- Give pairs a flashlight, a paper flap, and tape. Ask them to signal 'stop' across the room, check what their partner understood, then change and retest the signal.

Ways to Teach It
Tape a paper flap to a flashlight, sketch a plan for a 'stop' signal, and test it across the room.
Ask, 'How will your partner know what two flashes mean?' Have pairs write a signal key.
Play signal relay: partners send one or two flashes for agreed messages, record missed signals, then adjust the flashlight position.
Show a crosswalk signal photo, then ask students to draw how its light tells someone across the street to wait.
