Interactive Demo
The Diffusion Pipeline
The Diffusion Pipeline is a free, interactive learning demo from the AP Human Geography course on Lykke. It helps you build intuition for Cultural Diffusion (Expansion vs. Relocation), Cultural Landscape, Ethnocentrism vs. Cultural Relativism, Lingua Franca. Play with it directly in your browser — it features 5 buttons, direct drag interaction and a live visual canvas. This demo lives in the “Unit 3: Cultural Patterns and Processes” section of the course.

How to use this demo
- Click and drag directly on the canvas to manipulate the scene.
- Use the “Contagious”, “Hierarchical”, “Relocation”, “Stimulus” buttons to trigger actions or reset the demo.
- Experiment freely — there's nothing to break, and every change is reversible.
What you'll explore
- Cultural Diffusion (Expansion vs. Relocation)
- Cultural Landscape
- Ethnocentrism vs. Cultural Relativism
- Lingua Franca
- Universalizing vs. Ethnic Religions
- Acculturation and Assimilation
- Syncretism
Frequently asked questions
What does the The Diffusion Pipeline demo do?
Unit 3 examines the spatial distribution of cultural traits, including language, religion, and ethnicity. Students learn how culture diffuses from hearths to other regions and how the cultural landscape reflects the val… The Diffusion Pipeline turns that idea into something you can manipulate directly and watch respond.
What AP Human Geography concept does The Diffusion Pipeline teach?
Unit 3 examines the spatial distribution of cultural traits, including language, religion, and ethnicity. Students learn how culture diffuses from hearths to other regions and how the cultural landscape reflects the val… It focuses on Cultural Diffusion (Expansion vs. Relocation), Cultural Landscape, Ethnocentrism vs. Cultural Relativism, Lingua Franca, Universalizing vs. Ethnic Religions, Acculturation and Assimilation from the “Unit 3: Cultural Patterns and Processes” section.
What can I control in The Diffusion Pipeline?
You can drag elements directly on the canvas; the “Contagious”, “Hierarchical”, “Relocation”, “Stimulus” buttons run actions or reset the demo. Every change updates the visualization in real time, so you can see exactly how each variable affects the outcome.
How does The Diffusion Pipeline fit into the AP Human Geography course?
AP Human Geography introduces students to the systematic study of patterns and processes that have shaped human understanding, use, and alteration of Earth's surface. Students employ spatial concepts and landscape analy… This demo is the interactive piece for the “Unit 3: Cultural Patterns and Processes” section.

What will I understand better after using The Diffusion Pipeline?
You'll build intuition for Cultural Diffusion (Expansion vs. Relocation), Cultural Landscape, Ethnocentrism vs. Cultural Relativism, Lingua Franca, Universalizing vs. Ethnic Religions, Acculturation and Assimilation — and, crucially, see how they behave when you change the inputs, which is hard to get from a textbook or lecture on AP Human Geography alone.
