A tutorial that presents models of the atom proposed by John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr. Each is supported by an animated illustration. Includes comprehension questions and a quiz at the end.

This lesson 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 a...

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.

Looks at the scientists who developed the model of the atom by building on previous scientists' discoveries about its structure.

A classroom wiki where students present profiles of scientists who developed models of the atom or who contributed to the understanding of atomic theory. Covers Democritus, Aristotle, John Dalton, J.J. Thomson, Ernest Rutherford, Marie...

Describe how the model of the atom advanced as scientific knowledge increased. This lesson is 2 of 3 in the series titled "Models of the Atom."

Describe how the model of the atom advanced as scientific knowledge increased. This lesson is 1 of 3 in the series titled "Models of the Atom."

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...

[Free Registration/Login Required] Shown here are representations of three different models of the atom. Move the name labels to correctly title each of the models with the scientist who created them.

PBS offers a short summary of the discovery of the quantum nature of the atom by Max Planck. Easy to follow.

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site focuses specifically on the Periodic Table of Elements with information on the table's organization methods along with...

[Free Registration/Login may be required to access all resource tools.] Students take a closer look at how our understanding of the atom has evolved over time.

This StudyCard activity enables students to review the key contributions by scientists and philosophers towards are current understanding of the atom. It also allows students to review characteristics of the major atomic models.

[Free Registration/Login may be required to access all resource tools.] Rutherford's model of the atom was better than earlier models. But it wasn't the last word. Danish physicist Niels Bohr created a more accurate and useful model....

Acting as a subtopic of the General Chemistry Virtual Textbook's section on Atoms and the Periodic Table, this site discusses the properties of the atoms individually in relation to the main group elements of the Periodic Table.

A slideshow looking at the contributions of scientists over time to our understanding of atomic theory. Looks at models of the atom developed by Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, and James Chadwick, as...

A detailed slideshow for Grade 8 students that looks at the history of our understanding of atoms. Looks at the ideas presented by Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr, and the modern-day wave model. A...

An explanation of Niels Bohr's (1885 - 1962 CE) Model along with an app that illustrates a hydrogen atom according to the particle or wave model. You can choose a principal quantum number "n." The right part of the graphic represents the...

Introduces learners to atomic models of the past and present, focusing on the orbital model and an explanation of its basis. Learners then have the opportunity to "make an atom" and contrast it with an ion, followed by an isotope. The...

Activity 2 of the module explores: If you can't see it, how do you know it's there? Activities include the concepts of J.J. Thomson, electrons, and the Plum Pudding Model of the Atom.

Short slideshow looking at the history of models of the atom, including the contributions of Aristotle, Democritus, John Dalton, J.J. Thomson, Ernest Rutherford, and Niels Bohr.

Learn about Thomson's cathode ray experiment and the plum pudding model and Rutherford's gold foil experiment.

In this activity, students construct models of molecules using marshmallows and gum drops.
