Movement: Slides Past Each Other
AIR (Gale Cumulus) GAS
No fixed shape or volume; expands to fill space.
Draw Gas Particles
Spacing: Far Apart
Movement: Fast & Free in All Ways
2 Part 2: Ember's Fire & Thermal Energy (Particle Speed)
Fire = High Kinetic Energy!
In Element City, Ember Lumen is made of intense fire. In physical science, fire releases thermal energy (heat) . When thermal energy increases, particles absorb energy and move faster with higher kinetic energy.
Cooler Matter (Low Thermal Energy) ❄️ Slow
Particles move slowly, have lower kinetic energy, and stay held closely together by mutual attraction forces.
Heated Matter (High Thermal Energy) 🔥 Fast
Particles speed up, collide harder, and push farther apart as thermal energy overcomes particle bonds.
Question 1: In the film, Wade can squeeze through tiny water pipes, but Clod cannot. Using what you know about particle arrangement, explain why liquids can change shape while solids cannot.
Question 2: If Ember stands very close to Wade without touching him, steam begins rising from Wade's head. What is happening to Wade's water particles? What phase change is beginning?

3 Ember's Sand-to-Glass Workshop
Solid → Liquid → Solid
In one of the most famous scenes, Ember steps on beach sand and superheats it with her blue flame, turning grain-sized minerals into molten glowing glass, shapes a bubble, and allows it to cool into a strong, beautiful solid sculpture.
Step 1: Raw Sand Solid particles packed tight
SOLID STATE
Step 2: Molten Glass Ember adds thermal heat!
LIQUID (MELTING)
Step 3: Cool Vase Heat leaves; particles lock
SOLID (COOLING)
Is making glass a physical change or a chemical change? Explain why sand melting and cooling keeps the same basic particles:
4 Element City Scientific Case Studies
Apply NGSS Concepts
💧 Case A: Wade's Leak Seal
When the canal breaks, Wade gets trapped in a closed room. When Ember heats the room, Wade evaporates into steam. Later, water droplets form on the cool glass ceiling.
Name the two phase changes that occurred:
💨 Case B: Gale's Air Stadium
Gale Cumulus gets excited during the Air Ball game and expands her puffy cloud body to fill the entire section of seats.
Why can gas expand to fill large areas while liquids cannot?
5 Scientific Claim-Evidence-Reasoning (CER) Challenge
5-PS1-1 Scientific Argument
The Claim to Rebut: A student watches Wade evaporate and says: "Wade disappeared completely because his water matter was destroyed by Ember's fire and no longer exists."

STATION LAB GUIDE
Team Name / Number:
Class Period:
Inspector 1 (Timer): _________
Inspector 2 (Tools): _________
Inspector 3 (Recorder): _________
Inspector 4 (Presenter): _________
Four District Investigation Stations (7-8 Minutes Per Station) Follow safety rules at each station
🌱 STATION 1: EARTH DISTRICT SOLIDS
Investigation: Rigidity & Shape Retention
Place a solid wooden block inside a round cup, a flat tray, and a tall cylinder.
Observe: Does the solid block change its shape to fit the containers?
Attempt to gently squeeze the block with your hands. Can it be compressed?
Key Concept: Fixed shape and fixed volume because particles are locked in place.
💧 STATION 2: WATER DISTRICT LIQUIDS
Investigation: Flow & Fixed Volume
Measure exactly 50 mL of water in a graduated cylinder.
Pour that 50 mL into a flat dish, then pour it into a tall narrow tube.
Observe: Did the liquid shape change? Pour it back into the cylinder: Did volume change?
Key Concept: Definite volume but no definite shape; particles flow and slide.
💨 STATION 3: AIR DISTRICT GASES
Investigation: Compressibility of Gas
Pull back the plunger of a capped syringe to fill it with air (30 mL). Put your finger firmly over the tip.
Push down hard on the plunger. Can you compress the air?
Now fill the syringe with 30 mL of water, cap it, and push. Can you compress liquid?
Key Concept: Gas particles are spread far apart with empty space, allowing compression!
🔥 STATION 4: FIRE DISTRICT THERMAL ENERGY
Investigation: Kinetic Diffusion Race
Cup A contains ice water (Cold). Cup B contains warm water (Hot).
Simultaneously place 1 single drop of food coloring into both cups without stirring.
Start your timer! Observe how fast the color spreads in Cold vs Warm water over 60 seconds.
Key Concept: Heat increases particle speed (kinetic energy), causing faster collisions.

Synthesis & Analysis Questions
1. The Syringe Challenge: Why could you push the syringe plunger when it held Air, but could NOT push it when it held Water? What does this prove about the space between gas particles?
2. The Thermal Race: Why did food coloring spread throughout the warm water faster than the cold water? Explain using kinetic energy and particle speed.
🏙️ Element City Engineering Challenge: The Canal Repair Design Challenge
A crack in the Element City canal is leaking flood water into Firetown! Ember and Wade need to work together to seal the gap. Propose a physical science solution: How can Ember use high heat to melt a solid material (like glass or sand) to fill the crack, and how can Wade cool it down to solidify the barrier without putting Ember out?

📦 Low-Cost Station Lab Setup Guide
Station 1: Earth District (Solids)
Materials: 2-3 wooden blocks or river rocks, clear plastic cups, small shallow trays, graduated cylinders.Prep Note: Ensure blocks are smaller than the container opening so students see that shape does not conform to containers.
Station 2: Water District (Liquids)
Materials: Graduated cylinders (50-100 mL), clear cups of various widths, water pitcher with blue food coloring, pipettes.Prep Note: Tinting the water pale blue adds an authentic Wade Ripple feel and aids volume reading.
Station 3: Air District (Gases)
Materials: 2-3 plastic syringes (needleless, 30-60 mL), small rubber caps or student fingertip seal, party balloons.Prep Note: Test plungers beforehand to ensure smooth sliding when trapping air and water.
Station 4: Fire District (Thermal Energy)
Materials: 2 clear glasses per group (Cup A: ice water; Cup B: warm tap water ~105°F), dropper bottles of red food coloring, stopwatches.Prep Note: Emphasize not stirring the cups so students see molecular diffusion clearly.
⚠️ Key Science Misconceptions & Teacher Rebuttals
Misconception 1: "Particles in a solid are completely still and never move." Correction: Solid particles vibrate continuously in place around fixed lattice positions. They have low kinetic energy, but their particles never stop vibrating at everyday temperatures.
Misconception 2: "When water evaporates into steam, the water is destroyed." Correction: Evaporation is a physical phase change. The water particles separate and fly into the air as invisible water vapor. Matter is conserved; none disappears.
Misconception 3: "Heat/Fire is a physical substance made of atoms like solids and liquids." Correction: Heat is thermal energy transferred between substances; fire is glowing, reacting gases releasing light and thermal energy. High heat increases particle speed.

ANSWER KEY
📝 Worksheet Exemplar Answers
Part 1 Particle Models:
Earth (Solid): Tight, orderly grid/cluster of circles touching each other with vibration tick marks.Water (Liquid): Close together but disorganized; short curved arrows showing sliding motion.Air (Gas): Few circles spread far apart across the box with long straight motion arrows pointing in random directions.
Part 2 Application Questions:
Q1 (Wade vs Clod): Wade's liquid particles can slide past one another and flow, letting liquid take the shape of the pipe. Clod's solid particles are locked in place and cannot slip past each other.Q2 (Ember near Wade): Wade's water particles absorb thermal energy, speed up, and gain kinetic energy. The phase change is evaporation / vaporization into gas (steam).
Part 3 Ember's Glassmaking:
Physical Change: It is a physical change because melting silica/sand changes its state of matter from solid to liquid and back to solid, but does not create a new chemical substance. The particles remain silicon dioxide molecules.
Part 4 Case Studies:
Case A: Evaporation (liquid to gas) followed by Condensation (gas to liquid on cool ceiling).Case B: Gas particles have vast empty space between them and move freely, allowing them to expand to fill any volume, unlike liquids which have a fixed volume.
Part 5 CER Rebuttal:
Claim: Matter is NOT destroyed when Wade turns into steam; it merely changes state.Evidence & Reasoning: In physical science, water particles separate and move rapidly into the air as gas (water vapor). In a closed space, when the vapor cools, it condenses back into liquid water droplets of identical total mass (conservation of matter).
🔬 Station Lab Synthesis Key
Syringe Test: Air can be compressed because gas particles have large amounts of empty space between them. Water cannot be compressed because liquid particles are already packed closely.Thermal Race: In warm water, particles have higher thermal and kinetic energy, colliding with food coloring molecules much more frequently and dispersing them quickly.
🌟 Differentiation Strategies
Support (EL / Tier 2): Provide sentence frames for CER ("My claim is that matter is ____ because particles ____"). Use tactile marbles in a tray to model solids (packed), liquids (shaking), and gases (rolling free).Extension (Gifted): Ask students to calculate how temperature relates to density in Element City blimps (Gale's hot air currents vs cool drafts).
