Students calculate the Balmer series. In this physics lesson plan, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Students identify coal as the primary fuel used to generate electricity. After discussing coal's use in the generation of electricity, have students complete "When the Light Go Out" worksheet.

Students explore scientific discovery while watching a video. They, in groups, are to research a scientific invention and present their findings to the class.

Students identify the different periodic trends. In this chemistry instructional activity, students discuss how elements are arranged in the periodic table. They apply what they have learned in a Jeopardy team game.

Students explain how elements are arranged in the periodic table. In this chemistry lesson, students group the eggs according to a certain pattern. They compare this to elements in the periodic table.   

Students create a synthetic dye and oxidize the dye and record the effects.

Students investigate the effect human activities have on the environment. In this geography lesson, students compose an article using data analysis about the environment. This article requires some homework assignment.

In this resources worksheet, students compare and contrast physical and chemical properties and changes. Students review the periodic table, pattern of atomic numbers and chemical reactivity. This worksheet has 56 short answer questions.

Students creatively express themselves by creating simple pieces of music.

Young scholars interpret the information given in the periodic table to describe the arrangement of electrons on the energy levels around an atom.

[Free Registration/Login may be required to access all resource tools.] Covers energy levels of atoms, their relation to orbitals, and the significance of electrons at different energy levels.

This site describes the energy levels of atoms.

In this lab, students investigate basic electron structure by making a model using pennies and different sized filter papers.

An explanation of the different types of atomic orbitals, how they are filled according to the Pauli Exclusion Principle, and how many electrons can fit in each electron shell.

Find out how energy level models are represented on the Periodic Table of Elements.

Discover how covalent molecular bonding affects the energy levels of electrons.

Explore ionic molecular bonds and how electrons and their energy levels come into play.

This lab is designed to allow students to look at the connection between the gap between two energy levels and the frequency of the light that is given off when an electron traverses this gap.

A list of five virtual chemistry topics with Java applets on the electronic structure of coordination compounds. Covers crystal field theory, CFT energy level splitting, color in gems, the spectrochemical series, and ligand properties.

Young scholars discover that ionic bonding occurs when electrons are transferred from one atom to the other and not shared as in covalent bonding.

[Free Registration/Login Required] In this interactive you will excite an electron by dragging it into a higher orbital and use the table to see what wavelength of electromagnetic radiation is emitted when it returns to its lowest orbit....

Students discover the concept that two atoms can attract and form a covalent bond.

This site from Georgia State University gives information on the transitions of electrons between energy levels. The energy levels for electrons in the hydrogen atom are discussed. The Rydberg equation is stated and electron transitions...

A lab activity from an AP Physics course. Students measure the energy changes associated with electron level transitions to the second energy level for hydrogen gas. Includes directions and suggestions. Ideal for a student project or lab...
