This protocol simulation allows us to address fundamental questions about photosynthesis and cellular respiration
In this simulation, users will practice transforming bacterial cells with a recombinant plasmid using the heat shock method.

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.
Learn about membrane transport first-hand by modeling it using eggs!

Embark on a chemical discovery journey by immersing yourself in the world of acidity, basicity, and pH.
Explore how changing the numbers of protons, neutrons, and electrons affect the type of atom.

Why do atoms react with some elements but not others, and why do they form compounds with such different properties?
Understanding how elements combine and in what ratios helps us to understand the world around us.

Explore how the code embedded in DNA is translated into a protein.

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!
A very excellent platform for teaching-learning, I'm really enjoying it with my students.
