STEM Project Using Roblox Studio

Use Roblox Studio to explore building, gravity, structural integrity, testing, and creative problem solving through a hands-on virtual engineering challenge.

Part 1: Learn the Roblox Studio building basics

Roblox Studio lets students create virtual worlds using parts that have size, position, material, color, and physical properties. Before attempting the challenge, students should practice manipulating parts and building a simple structure.

Follow along to explore Roblox Studio parts and properties, then put those skills to work designing and testing a structure that stands on its own.

Part 2: Build a structure without anchoring

The challenge is simple to explain but surprisingly demanding: build a structure in Roblox Studio without using anchoring. The finished structure must support itself under Roblox physics.

Instructions

1. Start with a baseplate. Open a new Roblox Studio world and choose a simple baseplate.
2. Design your structure. Build a bridge, tower, shelter, or another structure without anchoring the parts.
3. Think about structural integrity. How can the parts support one another? Where are the weak points?
4. Test it. Run the game and observe what happens under gravity and player interaction.
5. Refine the design. Change the shape, supports, connections, or materials and test again.
6. Reflect. Explain what failed, what changed, and why the final version works better.

Why does my Roblox structure fall apart?

One of the most interesting parts of this challenge is discovering what happens when Roblox Studio’s physics system takes over.

In Roblox Studio, anchored parts stay fixed in place. Unanchored parts can move and respond to gravity and other physical forces.

That means a tower that looks perfectly stable while you’re building it might collapse as soon as you test the game. This is where the engineering challenge begins.

Try three experiments

Experiment 1: Build a simple tower. Stack several parts vertically without anchoring them. Run the game and observe what happens. Does the tower remain upright? Does it lean or collapse? Which parts move first?

Experiment 2: Change the base. Try rebuilding the same tower with a wider base. Keep the other parts as similar as possible so you can compare the results. Does changing the base make the structure behave differently?

Experiment 3: Change one more feature. Experiment with the shape, position, or arrangement of the parts. You can also investigate how Roblox Studio’s different physical properties affect the structure. Test again and compare what happens.

Questions parents can ask

You don’t have to know Roblox Studio to have a useful conversation about the project. Ask your child:

• What did you expect to happen?
• What actually happened when you tested it?
• What did you change between your first and second attempts?
• What would you try next?

Encourage your child to explain what they noticed instead of immediately looking for the correct solution.

What students practice

This project combines technology, engineering, creativity, and iteration. Students are not just decorating a virtual world—they are making a design, observing how it behaves, and using evidence to improve it.
