Pre-Application Activities

Before Zoe Experience
  1. Review with students what is Red and Blue Litmus paper. You may want to use this site to help you: https://byjus.com/chemistry/litmus-paper/.
  1. Ask the students the following questions:

    1. What are the main components of litmus paper, and how is it used to distinguish between acid and basic substances?

    2. Describe the color change that occurs when litmus paper is dipped in an acidic solution versus a basic solution.

    3. Give an example of a liquid that would turn Blue litmus paper red.

    4. Give an example of a liquid that would turn Red litmus paper blue.

Instructions While Inside the Zoe Experience

  1. Instruct students before they go into Zoe what their tasks are:

    1. Have them download and launch the scene from the community library called Acids and Bases.

    2. Then, have students click the Play button in Zoe.

    3. In this experience, students will use the Red and Blue litmus paper to determine whether each substance is an acid or a base.

Break Free from Passive Learning: Engage and Create with Zoe Immersive VR

Imagine turning education into an experience where students aren't just sitting and listening—they're creating. VR education, particularly Zoe Immersive, gives students the reins to design entire worlds where math isn't just about numbers, it’s calculating range for underwater exploration; history isn’t a series of facts, it’s a first-person exploration of artifacts from fascinating eras; plot isn't confined to the written word, it’s a lived narrative that is visually laid out for all to see and feel. In virtual reality, the learning is real because it is owned by the students. They are not watching the adventure, they are living it. Heck, they are actually creating it.

Zoe Immersive makes VR approachable for educators and students. No coding skills? No problem. Its user-friendly setup means anyone can start building right away. If VR technology makes you nervous, Zoe's user-friendly format will change your mind. It's simple and stress-free to integrate into the curriculum. It keeps things straightforward, letting teachers focus on what's important: helping students learn and create something new.

Are you interested in VR turning students into creators? Let's make it a reality. Schedule a demo with Zoe Immersive and see how seamless and effective VR integration can be. Discover how our platform can re-energize teaching and return learning to an active, engaging process.
