For this physics worksheet, students develop an understanding of the atomic model and how atoms relate to one another through answering the seven questions.

In this atomic models time line worksheet, students draw a diagram of Democritus, Dalton, Thomson, Rutherford and the Electron Cloud model of the atom.

Students study the significance of the quantum model and how scientific theories adapt over time.  In this investigative lesson students describe the contributions that scientists have helped develop the atomic theory and identify...

Trace the sequential process of the developing theories of atomic structure in the early 20th century, show, in historical development, how scientists "know" things, how experiments are set up and how interpretations are drawn from them,...

Students investigate what is wrong with the Rutherford atomic model. In this chemistry instructional activity, students answer questions about the atomic model after watching a video. They draw conclusions from the video and discuss how...

Students apply the principles of chemistry to investigate the concept of how a hydrogen powered car works. They study the electrochemical reactions that provide the energy source. Students also record observations in the functioning of a...

Students examine the electromagnetic spectrum and demonstrate the elements within.  In this investigative lesson plan students complete a demonstration and calculate the energy of a photon. 

Through a study of Ernest Rutherford's experiments with atomic structure, students develop a deeper understanding of the nature of science. The activity is taken from a linked article by the author that was published in the Journal of...
