Trace the development of the atomic theory from Democritus to the Quantum Mechanical (Electron Cloud) Model.

Examine how each scientist’s discovery changed our understanding of the atom.

Build a 3D model of the Bohr atom and explain how it improved upon earlier models.

Communicate your understanding through a slideshow presentation and oral explanation.

Demonstrate collaboration, creativity, and understanding of the evolution of atomic theory. 

Choose project type (Bohr Model + Slideshow)
