The Secret Signal Problem
Two explorers are in the deep jungle. They need to share secret messages without waking up a sleeping jaguar!
They are too far apart to whisper, but shouting is too dangerous.
How can we send sound through a wire or string?
What is Sound?
Vibrations
Sound is made when things wiggle back and forth very fast!
Sound Waves
These vibrations travel through air, water, or even solid strings!
Activity 1
Vibration Station
Let's see sound in action! We will build a simple instrument to "see" the wiggles.
Get a box and 3 rubber bands.
Stretch bands over the opening.
Pluck and watch the vibration!
Mission Checklist:
• Does a tighter band sound higher?
• Can you stop the sound by touching the band?
• Why does it stop?
Activity 2
The Super Cup-Phone
Time to solve the jungle problem! We will send vibrations through a string.
1
Poke a hole in the bottom of 2 cups.
2
Thread string through and tie a knot.
3
Pull tight and WHISPER!
!
"Can you hear me now?"
Engineering Recap
Vibrate
To make sound, something must move!
Travel
Sound moves through the string to the other cup.
Solve
Explorers are safe. No jaguars woken up!

Supply List (Per Student/Pair)
Activity 1: Vibration Station
• 1 Small box (tissue box or shoe box)
• 3-4 Rubber bands of different widths
• 1 Ruler or pencil (to act as a bridge)
Activity 2: Super Cup-Phone
• 2 Plastic or paper cups
• 10-15 feet of Cotton string or yarn
• 1 Paperclip (optional, to secure string)
• Push pin or sharp pencil (Teacher use recommended)
Instructional Script
Hook & Introduction (5 mins)
"Class, put your fingers on your throat and hum. Do you feel that wiggling? That is a vibration ! Every sound you hear—a dog barking, music, or me talking—starts with a vibration. Today, we are going to be sound engineers to help two jungle explorers send secret messages without waking up a jaguar!"
Activity 1: 30 Mins
1. Have students stretch rubber bands over the box opening.Demonstrate: Pluck a band. "Look at the band! Is it moving?"Challenge: Make a 'loud' vibration and a 'quiet' vibration. How does the wiggle change?Stop the sound: Touch the band while it's wiggling. "Why did the sound stop?" (Answer: The vibration stopped).
Activity 2: 30 Mins
1. Pre-poke holes in the bottom of cups for younger students.The Rule: The string MUST be tight (taught). If it's loose, the vibrations "get lost" in the droop.Test: One student whispers, the other listens. "How is the sound moving?" (It travels through the string!).

STAAR Review & Answer Key
Teacher Reference Only
Mission Log Answers
1. Rubber band hard pluck:
Students should draw wide, blurry-looking lines to represent large vibrations.
2. Touching the band:
The vibration stops and the sound stops immediately.
3. Loose string:
No. Vibrations cannot travel through loose, floppy string easily.
Review Questions
Q1: Which of these makes sound by vibrating?
A. A still rock
Q2: Why do we whisper in a library?
To keep the sound level low so we don't bother others. (TEKS 2.8B)
Pro-Tip for Easy Setup
Collect tissue boxes for two weeks before the lesson. Use dental floss if cotton string is unavailable—it actually transmits sound very well due to its thinness and strength! For the cup phones, have students decorate their "secret signal devices" with markers to increase the 'wow factor'.

Lab Management Tips
The "1-2-3 Eyes on Me" Rule: Establish a clear signal to stop all testing. STEM labs get loud! Ensure students know that when the signal is given, hands come off supplies.
Material Managers: Assign one student per group to be the ONLY one allowed to visit the supply station. This prevents crowding and supply loss.
Station Rotation: If supplies are limited, run the two activities as stations that groups rotate through every 15-20 minutes.
Data First: Require students to show their Mission Log predictions before they receive the final "wow" piece (like the battery or the laser/flashlight).

Facilitation Guide
Activity 1: The Sorting Safari
Guide students through the classroom, cafeteria, or playground. Challenge them to find "hidden" energy.Tip: Look at the ceiling (light), the vents (thermal), the clock (mechanical), and the speaker (sound).
Key Questions:
"Is the light energy coming from a natural source (sun) or artificial (lamp)?"
"Does the thermal energy feel warm to your hand or can you see it (boiling water)?"
Activity 2: Engineering The Zoom
Students often confuse "Wind" with energy. Explain that the Mechanical Energy is in the movement of the balloon. The air provides the force .
The Challenge: Adjust the air volume. Does more air mean more energy?

Facilitator Script & Pacing
Phase 1: Hook (5 Mins)
"Engineers, imagine you are in a dark shelter after a storm. Your flashlight is in pieces! You have a battery, a bulb, and a roll of foil. How can you get the energy from that battery to the light? It must be a closed path —no gaps allowed!"
Phase 2: Build (25 Mins)
Guide students to fold the foil into "wires." The Trick: One foil strip must touch the bottom of the battery and the side of the bulb. The top of the battery must touch the bottom of the bulb. This completes the loop.
Phase 3: Test (35 Mins)
Introduce the "Mystery Objects." Students break their foil connection and insert an object to bridge the gap. Data Focus: If the light stays on, it is a Conductor . If it goes out, it is an Insulator .
