01 Energy in the Game
The Body as a Lab
Athletes need energy for every stride. This energy comes from chemical reactions happening inside their cells.
"Heat is the byproduct of an athlete working hard."
The Temperature Check
Does the reaction release heat to warm the body, or absorb it to cool an injury?
HOT
Exothermic
COLD
Endothermic
Type A: The Energy Release
EXO-thermic
Energy is released . This is how we produce Body Heat during a workout.
1
Fuel (food) reacts with Oxygen
2
Bonds break and reform
3
Excess energy leaves as HEAT
Sports Example
"Hand Warmers on the sidelines!"
Type B: The Heat Thief
ENDO-thermic
Sports Example
"Instant Cold Packs for a sprained ankle!"
Energy is absorbed . It steals heat from the body to make the reaction happen.
1
Reaction requires a massive energy boost
2
It "sucks" heat out of the air/skin
3
The pack feels FREEZING
In a Hurry?
In the Olympics, milliseconds matter. In chemistry, the speed of your "fuel processing" matters too.

Phase 03: The Talk
Reveal & Connect
Connect their choices to chemistry: Temperature, Surface Area, and Concentration. Discuss athletic benefits of each speed factor.
Performance Prompts
Energy Logic: "If you're freezing on the sidelines, which reaction do you want inside your gloves?"
Kinetics Logic: "Why do athletes 'warm up'? How does heat change the body's chemistry processing speed?"
Factor Reveal
Choice 1 (Temp): Warm water = higher particle kinetic energy.
Choice 2 (Form): Smashed = more exposed surface area/hit zones.
Choice 3 (Density): Concentrated = more frequent collisions.
Sim A: Exothermic Result
Evidence: Temp rise (~15°C). Energy leaves the system. Perfect for body heat or hand warmers.
Sim B: Endothermic Result
Evidence: Temp drop (~10°C). Energy enters the system. Ideal for cooling injury sites.
Coach's Tip:
Remind students that 'Cold' reactions aren't producing cold—they are removing heat from the surroundings. This is a common misconception.

01 The Engineering Challenge
If bones were made of solid rock , we'd be strong—but too heavy to move.
"How does nature make something incredibly strong but light enough for a bird to fly or a human to run?"
Inquiry Question
What's inside?
The Outer Guard
Compact Bone
1
Dense and heavy material.
2
The "hard shell" on the outside.
3
Protects against big impacts.
Think of it like:
"The steel pipe that holds up a skyscraper."
The Inner Mesh
Spongy Bone
Think of it like:
"The honeycomb structure of a bee hive."
1
Full of tiny holes and pores.
2
Lightweight and flexible.
3
Located at the ends of bones.
Why Both?
Shock Absorption
When you jump, the spongy bone acts like a spring, spreading the force out.
Storage Space
The holes in spongy bone are filled with bone marrow—the factory for your blood cells.

The Hidden Map
Bones aren't just solid white sticks. They are complex machines with two distinct types of tissue. Your goal is to identify them and figure out why they look so different.
Part 1: The Comparison
Look at the two samples provided by your teacher. Describe what you see.
Sample A: The Shell
Texture / Appearance:
How many holes can you see?
This is COMPACT BONE.
Sample B: The Core
Texture / Appearance:
What does the structure remind you of?
This is SPONGY BONE.
Part 2: Engineering Analysis
1. Weight Watchers: Why isn't your entire femur (thigh bone) made of solid Compact Bone?
2. Shock Absorbers: Spongy bone is found at the ends of bones. Why is it useful there during a jump?
3. Body Armor: Why is compact bone always found on the outside of the bone shaft?
The Discovery Conclusion
"Form follows function" means that the way something is built tells you exactly what it's supposed to do.
Write one sentence explaining how Compact and Spongy bone work together as a team:

Answer Key
Grading Overview
Students should demonstrate a clear understanding that temperature change is the primary evidence of energy moving in or out of a chemical system. Data points below are representative of typical results.
A
Yeast + Hydrogen Peroxide
Initial Temp (Typical): ~21°C
Final Temp (Typical): ~38°C
Expected Observations: Rapid bubbling/foaming, steam may be visible, the cup feels significantly warmer to the touch.
B
Vinegar + Baking Soda
Initial Temp (Typical): ~21°C
Final Temp (Typical): ~14°C
Expected Observations: Aggressive fizzing/bubbling, the liquid appears "milky" then clears, the cup feels cold or chilled.
Analysis Solutions
1. Classification:
Exp A: Exothermic
Exp B: Endothermic
2. In an endothermic reaction, where is the heat going?
The heat is being pulled into the chemical reaction from the surrounding environment (like the thermometer or the cup). This is why the surroundings get colder.
3. Which reaction would make a better hand warmer?
Experiment A . Since it is exothermic, it releases heat energy to the outside, which would warm up your hands.
4. Bonus: Why did the temperature drop in Experiment B?
The reaction needs more energy to break and reform the chemical bonds than it releases. It "borrows" this extra energy in the form of heat from the water and container.

Answer Key
Key Objective
To guide students toward discovering the three main factors of reaction rates: Temperature , Surface Area , and Concentration through direct observation.
Choice 1: Temperature
A: Cold ~60s
B: Hot ~8s
Choice 2: Form
C: Whole ~40s
D: Smashed ~12s
Choice 3: Strength
E: Watery ~30s
F: Pure ~15s
The Engineer's Final Report
1. Biggest Win:
Typically Hot Water shows the most dramatic reduction in time. Students should use their specific data points to prove why their choice saved the most time.
2. Particle Logic:
Smashed tablets have more exposed surface . Since the reaction happens on the surface, more particles can react at the same time, speeding everything up.
The Ultimate Speed Recipe:
"I would use very hot , full strength liquid and smash the tablet into a powder. This combination provides the most energy and the most surface area for collisions."

Bone Discovery Answer Key Inside Information - Model Answers
Tissue Investigation Key: BONE_KEY_002
Answer Key
Part 1: The Comparison
Sample A: Compact Bone
Observations:
Dense, solid, and white. Looks like ivory or hard plastic. It has a very smooth surface and feels heavy for its size.
Hole Count:
No visible holes to the naked eye. It looks completely filled in.
Sample B: Spongy Bone
Observations:
Porous and web-like. It looks like a complex lattice of tiny bone needles. It has many visible gaps and spaces.
Metaphor:
A sponge, a honeycomb, or a spider web. It looks much lighter than compact bone.
Part 2: Engineering Analysis
1. Weight Watchers: Why isn't the femur made entirely of solid Compact Bone?
If the femur was solid compact bone, it would be extremely heavy. Our muscles wouldn't be strong enough to lift our legs easily. Spongy bone provides strength while keeping the bone lightweight.
2. Shock Absorbers:
Spongy bone’s lattice can flex slightly. This absorbs the energy of an impact (like jumping) and protects the rest of the bone from cracking.
3. Body Armor:
Compact bone is hard and dense to protect the bone from outside hits and support the weight of the body.
The Discovery Conclusion
Model Response: "Compact bone acts as a strong outer shield for support and protection, while spongy bone makes the bone light and helps it absorb shock from movement."
