Inside an Atom

Wow, an experiment that allows the class to participate in a missile war! Pupils discuss Thomsons's theory of cathode rays and simulate Rutherford's historical experiment to learn about atomic structure. They conclude this fourth lesson...

In this Rutherford model learning exercise, students read about Rutherford's experiment with gold foil and alpha particles which led to the discovery of subatomic particles. Students answer six analysis questions about the experiment and...

In these chapter test worksheets students will multiple choice questions on atoms. Students will complete 77 questions on atoms to complete the chapter test.

What does the past have to do with today? Young scientists find that answer as they learn more about past chemists and their significant contributions to the field. Pupils use the Internet to research historical figures and create a...

Neat! Show your physics class exactly how Ernest Rutherford fired alpha particles at a piece of gold foil and so determined that most of an atom is composed of empty space. Not just a slide show, but almost an animation, this...

How do we know so much about the atom? Explore the evolution of the atomic model through a video from an informative chemistry lessons playlist. The narrator describes how our view of atoms and subatomic particles has changed from...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

Historically, scientists had to be creative to study subatomic structure. Scholars step into their minds to recreate the procedure Rutherford used to create his atomic model. Learners identify the creative efforts of early scientists...

How did Rutherford figure out the structure of the atom without being able to see it? Simulate the famous experiment in which he disproved the Plum Pudding model of the atom by observing alpha particles bouncing off atoms and determining...

Students investigate the structure of the atom and its composition. In this atom structure lesson, students find the area of cut out circles and drop pens into the circles. They count the number of marks in the circles and relate their...
