This lesson plan introduces students to scientific models. The students will learn how models of the atom have changed as new evidence is gathered. The students will also learn about the current model of the atom. Each student will make...

Resource investigates how Bohr's model of hydrogen explains atomic emission spectra.

Students build atoms of elements 1-20. The entire set can be hung from the ceiling in order of the Periodic Table to be referred to throughout the Chemistry class/unit. This is helpful when teaching bonding and patterns of the Periodic...

Discusses models of the atom developed by John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick. Includes clear illustrations and a short comprehension exercise at the end.

How did scientists figure out the structure of atoms without looking at them? Try out different models by shooting light at the atom. Check how the prediction of the model matches the experimental results.

Presents models of the atom developed by Thomson, Rutherford, Bohr, and Schrodinger. Includes successes and failures of each, illustrations, and detailed descriptions. Also discusses Dirac's model of the atom and introduces quantum...

Learn about the models of the atom that have been proposed throughout history. Presents Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and the modern theory of the atom. Sections are accompanied by journal...

In this activity, students will explore several different models of the hydrogen atom and compare and contrast them using an online java applet.

How Bohr's model of hydrogen explains atomic emission spectra.

Learn about atomic structure and the multiple theories of atomic structure in this simulation.

An explanation using quantum mechanics to describe the atom.

Students create models of atoms then compare the various aspects of the atoms including; relative size, charge, positions of subatomic particles, and identity of the atom based on proton, neutron, and electrons with the class.

Introduction to the quantum mechanical model of the atom: Thinking about electrons as probabilistic matter waves using the de Broglie wavelength, the Schrodinger equation, and the Heisenberg uncertainty principle. Electron spin and the...

Describe how the model of the atom advanced as scientific knowledge increased. This lesson is 3 of 3 in the series titled "Models of the Atom."

Brief explanation of six major models of the atom along with illustrations. Covers the Greek model (Democritus), John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and the modern electron cloud or quantum mechanics model.

Students work as engineers to learn about the properties of molecules and how they move in 3D space through the use of LEGO MINDSTORMS NXT robotics. They design and build molecular models and use different robotic sensors to control the...
