Planning science lessons takes time—even before class begins.

LabXchange was designed to reduce the lesson prep burden while supporting meaningful science learning.

A teaching support system—not just a content library.

LabXchange brings together free, high-quality interactive science resources that educators can use immediately or adapt to their needs. Virtual labs, curated pathways, and multimedia tools help you plan more efficiently, reinforce key concepts, and give students hands-on learning experiences—all in one place.

  1. Ready-to-use resources

    Use as-is or adapt quickly for your classroom.

  2. Interactive learning tools

    Help students engage with complex concepts.

  3. Flexible for any setting

    Utilize in class, as homework, or for independent learning.

Designed to fit into how you teach.

Plan and structure lessons more efficiently

Use expert-designed learning pathways that organize videos, simulations, and questions into clear instructional sequences. Adopt them as-is or adapt them to fit your curriculum and pacing.
Browse learning pathways

 Bring lab experiences into more classrooms

Use virtual labs to support pre-lab preparation, reinforce techniques, or provide hands-on learning when physical labs aren’t possible.
Explore virtual labs

Support understanding beyond the lesson

Assign videos, interactives, and question sets so students can revisit concepts and apply learning independently—without creating new materials.
Explore interactive resources

 Explore resources you can use right away

LabXchange brings together resources curated from 200+ trusted sources, so you can spend less time searching and more time teaching.
Photosynthesis

This protocol simulation allows us to address fundamental questions about photosynthesis and cellular respiration

Transforming Bacteria

In this simulation, users will practice transforming bacterial cells with a recombinant plasmid using the heat shock method.

Mitosis

Explore mitosis in this virtual lab! Here, you will analyze scallion root tip cells to determine the effect of lectins on the rate of mitosis.

The Egg Lab

My personal fav? LabXchange! It feels like a game but teaches you serious stuff like PCR, ELISA, CRISPR, etc. Bonus: They even have NCERT class 11–12 biology & chemistry content covered!
