Young scholars define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an...

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

Eighth graders view a PowerPoint presentation that assist them in distinguishing between physical and chemical changes. They compare their observations of demonstrations to a list of clues recognizing types of changes.

Students identify how to relate the position of an element in the periodic table to its atomic number and atomic mass. They identify how to use the periodic table to identify metals, semimetals, nonmetals, and halogens, and also,...

Students discuss the mass-energy relationship based on Einstein's work. They calculate the energy released in various scenerios and sketch diagrams for the Lyman, Balmer and Pfund Series. In groups, they discuss the role of photons and...

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

Students explain that the Standard Model of the atom includes particles beyond protons, neutrons, and electrons. They describe the nucleus as conglomeration of quarks that manifest themselves as protons and neutrons.
