Examining Microorganisms in a Water Sample

An interactive experiment demonstrating how to observe DNA in onion root tip cells. The experiment involves cutting a small part of the root tip, preparing and staining it with acetocarmine, examining the sample under a microscope at different magnifications, and counting the visible cells and the c......

Relationship Between Electron Energy and Its Position in the Atom

A simplified simulation of Rutherford’s experiment showing how hidden objects can be inferred by observing the paths and deflections of balls when they collide with them, similar to Rutherford’s inference of a small, dense nucleus inside the atom from the deflection of alpha particles.Rutherford Exp......
