The Earth Layer Challenge
A Special Mission for Families!
Can you eat your way to the center of the Earth? We are launching a special home science project to explore the layers of our planet!
Using the instructions sent home, your family will work together to create an edible model of the Earth. When you slice it open, will we see the layers inside?
Step 1: Watch
Scan the code or visit the link to watch "Build Earth from the Inside Out!" with Jessi and Squeaks. Pay close attention to the layers!

Step 2: Create
Bake a cake or make Rice Krispie treats using our secret color code:
Inner Core (Hottest!)
Outer Core
Mantle (Thickest!)
Crust (Thinnest!)
The Big Reveal
Take a photo of your family cutting into the "Earth" and showing the layers. Bring the photo back to school by Friday to help build our "Sweet Science" bulletin board!

Family Mission Briefing
Science Lab: Kitchen
"Dear Families, we're taking our science learning into the kitchen! No one has ever seen the center of the Earth because it's too hot and too deep. But we can build a model to see how it works. Join your student in this delicious geological adventure!"
Supply List
Cake Mix (or Rice Krispie Treat ingredients)
Food Coloring (Red, Orange, Yellow)
Chocolate Frosting (The Crust!)
Camera or Phone
Preparation
Before you start, watch the video together to see the science in action!

The 4-Layer Build
1
Inner Core (Red)
Bake a small round cake (or roll a ball of red treats). This is the hottest part of Earth, and it's solid!
2
Outer Core (Orange)
Wrap the red core in an orange layer. In real life, this layer is actually liquid metal!
3
The Mantle (Yellow)
This is the thickest layer. Make this layer double the size of the others. It's made of hot, melted rock.
4
The Crust (Chocolate)
Frost the entire model in chocolate. The crust is the thinnest layer. Don't forget to add blue/green sprinkles for oceans and land!
Science Talk
• Which layer is the thinnest?
• Why did we use red for the center?
• What happens to the temperature as we go deeper?
The Photo Reveal
Have a grown-up slice the "Earth" in half. Take a photo of the cross-section to show off your layers!

Label the Layers
Crust
Mantle
Outer Core
Inner Core
Which layer did you make the thickest?
1. What is one fact you taught your family while making this?
2. Why did we use different colors for the layers?
3. How was the crust different from the mantle?

Teacher Implementation Guide
Instructional Goal
This home-school connection project bridges classroom earth science with family engagement. Students apply their knowledge of Earth's internal structure by acting as the "expert" during a family baking project.
Recommended Pacing
Monday: Send home the **Sweet Science Flyer**. Generate excitement!
Wed/Thurs: Send the **Instruction Sheet**. Encourage families to watch the video.
Friday: Photos and **Reflection Sheets** returned for the class gallery.
Core Content
"Build Earth from the Inside Out!"
Duration: 5:44
Gallery Wall Idea
"Our World is Sweet!"
Mount the family photos on large brown paper "crust" circles. Place the student reflection sheets underneath. This creates a high-visibility connection point for families during school visits.
Differentiation
No-Bake Option: Use Rice Krispie treats or even play-dough as suggested in the video.Digital Submission: Allow families to email photos if printing at home is a barrier.Drawing Alt: Students can draw their "dream Earth cake" if the project cannot be completed at home.
Facilitation Tips
The Model Concept
Emphasize that models are "small copies" of big things. Remind students that we can't go to the center, so models are how scientists learn.
Color Meaning
Reiterate Jessi's color choices: Red for the hottest inner core, Yellow for the thickest mantle, Brown for the cool crust.
Thickness Ratio
Remind families that the Mantle should be the biggest layer, while the Crust is just a thin "skin" of frosting.
