• For the Chemistry/Art Activity:
  • Natural materials gathered from outside (mud, clay, crushed green leaves, berries, charcoal from a fire pit, or spices like turmeric and cocoa powder from the kitchen)
  • A small amount of water and dish soap (to act as a binder)
  • Paintbrushes or cotton swabs
  • Thick watercolor paper or smooth cardboard
• For the Survival Challenge:
  • One small plastic toy, a grey rock, or a small household object (this will be your "tribute" to camouflage)
  • A digital camera, tablet, or phone

Learning Objectives & Success Criteria

1. Introduction: The Hook (10 Minutes)

This is exactly the scenario Peeta Mellark faces in Chapter 17 of The Hunger Games. Instead of using force, Peeta uses his knowledge of color, texture, and shadow to paint himself into a muddy stream bank, blending so perfectly with the rocks and mud that Katniss almost steps on his head!

Today, we are going to explore the biology of how animals do this naturally, the chemistry of how Peeta made his paints from scratch, and put your own camouflage skills to the test!

2. Direct Instruction: "I Do" (20 Minutes)

Part A: The Biology of Camouflage

In the wild, camouflage is an evolutionary adaptation that helps both predators (to sneak up on prey) and prey (to hide from predators). There are three primary strategies used in nature:

1. Background Matching (Crypsis): The animal’s colors and patterns match the environment exactly.
   Example: A green tree frog on a green leaf, or Peeta matching the grey stones and brown mud of the creek bank.
2. Disruptive Coloration: High-contrast patterns that break up the outline of an animal's body, making it hard to see where the animal starts and ends.
   Example: A zebra's stripes or a leopard's spots. When they move in groups or in dappled sunlight, predators can't target a single individual.
3. Masquerade: The animal looks like an entirely different, uninteresting object, like a leaf, stick, or bird dropping.
   Example: A walking stick insect or a leaf-tailed gecko.

Part B: The Chemistry of Natural Pigments

Peeta didn't have a paint set in the arena. He had to use what the earth provided. This is how humans painted for thousands of years (think of ancient cave paintings!).

To make paint, you need two basic scientific components:

• Pigment: The raw material that provides the color. These are typically insoluble solids (meaning they don't fully dissolve in water).
  • Charcoal/Carbon = Black and deep grey
  • Iron Oxide (Clay/Rust) = Red, orange, and yellow
  • Chlorophyll (Leaves) = Green
  • Anthocyanins (Berries) = Blue, purple, and red
• Binder: A sticky substance that holds the pigment together and helps it adhere to the surface (skin, rock, or canvas). Peeta likely used mud, clay, or sap. In modern paints, we use acrylic polymers or oils. Today, we will use a tiny drop of dish soap or glue mixed with water.

3. Guided Practice: "We Do" (20 Minutes)

Let's work together to analyze Peeta's strategy and test our pigment-making skills. (If homeschooling, do this alongside your parent/educator; if in a classroom, work with a partner).

4. Independent Practice: "You Do" (30 Minutes)

The Arena Camouflage Challenge

Now it's your turn to play the role of Peeta Mellark in the arena. You must save a "tribute" (your small toy, a stone, or a small household item) from the Gamemakers' searches by camouflaging it!

Your Mission Steps:

1. Select your "Arena" (Environment): Pick a specific spot in your yard, house, or a houseplants pot (e.g., a patch of grass, a pile of dry leaves, a woodpile, or a brick wall).
2. Analyze the Background: Look closely at your chosen spot. What are the dominant colors? What are the textures? Is it rough, smooth, shiny, or matte?
3. Create Your Camouflage Paint: Gather and mix natural pigments (mud, clay, charcoal, berries, crushed leaves) using your binder to match the exact colors of your environment.
4. Paint Your Tribute: Gently paint your toy, rock, or object using your natural paint mixture. Use disruptive coloration (breaking up its solid outline) or background matching.
   Note: If using a plastic toy you want to save, wrap it tightly in aluminum foil or masking tape first, then paint on top of the wrapping!
5. The Placement: Place your camouflaged tribute back into the chosen environment.

5. Conclusion: Reflection & Recap (10 Minutes)

Let's wrap up what we learned today about literature, science, and survival!

Assessment & Grading Criteria

Adaptations & Extensions

For Advanced Learners (Extensions):

• Military History Integration: Research the history of military camouflage. Look up "Dazzle Camouflage" used on ships in World War I. How does this connect to *disruptive coloration*? Write a short 1-page report or draw a picture of a ship using this pattern.
• Chemical Analysis: Research why berry colors change depending on the pH level of what they are mixed with (anthocyanins as pH indicators). Try mixing blueberry juice with vinegar (acidic) and then baking soda (basic) and note the color changes.

For Scaffolded Learning (Support):

• Art Alternative: If creating paint from natural elements is too messy or materials are scarce, use washable watercolor paints or crayons. Focus entirely on mimicking the textures and patterns of a chosen household background on a piece of paper cut into the shape of a leaf.
