#1 of #DEXR100 is about exploring the planets and their place in space.

Use the embedded 3D viewer below to try it out yourself.

Description

In this lesson you'll get to know the planets of our solar system, while floating in space! 

Learning Goals

By the end of this lesson, students will be able to:

• Recognize the eight planets of our solar system.
• Understand the order of the planets from the Sun.
• Identify key features that make each planet unique.
• Explain the concepts of rotation and orbit in simple terms.

How to use in the classroom

• This lesson works well as an introduction to the concept of the solar system.
• It is designed for learning facts and concepts.
• The intended age range is K–12 students.

How it's made - behind the scenes

We started with free-to-use NASA models and textures and brought them into Blender, adding simple animations so each planet reflects its real rotation and orbit around the Sun. Using our Blender add-on, we pushed the assets straight to our Dexr platform and iterated quickly. Updates propagate instantly thanks to real-time libraries and asset streaming.

Inside the web-based, no-code editor, we built the lesson flow with Events & Actions (e.g., revealing planets, toggling orbits, and short knowledge checks), added TTS narration with a 3D guide, and used push guidance panels for context. Everything runs in the browser, no installs needed, so it’s easy to use in class. For teachers, learner accounts and tracking help monitor progress, guided by our LEAP learning framework.
