Roblox Ecosystems: Build a Food Web Island

Ecosystems are all about connections, and building one in Roblox makes those connections visible. In this eight-week course learners in grades 3 to 5 design an island ecosystem and learn how living things depend on each other.

Learners begin by shaping an island with Roblox terrain tools, adding a beach, a forest, a pond and a grassy meadow. They learn about habitats and what plants and animals need to survive. Next they explore producers, consumers and decomposers and place simple models of each in the right habitat with labels that explain their role.

In the middle weeks learners trace food chains, starting with sunlight and plants and moving to herbivores and predators. They then connect several food chains into a food web using signs and arrows across their island. Learners ask what would happen if one species disappeared and test ideas by removing parts of their web and discussing the effects.

In the final weeks learners explore adaptations, such as camouflage and special beaks, and design a new imaginary animal that fits one of their habitats. They finish with a guided island tour where they explain how energy moves through their ecosystem.

The teacher uses diagrams and real examples to explain each idea, and learners build what they learn. No coding experience is required.

How classes work

Each class pairs a short life science lesson with a building task on the learner's island. Learners finish each class by explaining one new connection in their food web.

What we'll cover

• Week 1: Island Habitats – Shape an island with beach, forest, pond and meadow.

• Week 2: Living Things' Needs – Learn what plants and animals need to survive.

• Week 3: Producers and Consumers – Place and label producers and consumers.

• Week 4: Decomposers – Add decomposers and explain their role.

• Week 5: Food Chains – Trace energy from sunlight to predators.

• Week 6: Food Webs – Connect food chains with signs and arrows.

• Week 7: Adaptations – Design an imaginary animal adapted to a habitat.

• Week 8: Island Tour – Lead a tour explaining how energy moves through the ecosystem.

No coding experience needed. Learners should be able to move and resize parts in Roblox Studio.
