Periodic table
This lesson provides knowledge about periodic law, groups and periods. Students will be able to identify and label each group with their names. Students will be able to relate atomic number and atomic masses of different elements of periodic table. Students will also be able to discuss periodicity of different properties of elements.

Atomic spectra and the Bohr model
Students view continuous spectra from incandescent and fluorescent lights and line spectra of selected elements. Students relate energy to frequency of light seen in the spectra. The presence of only certain lines in atomic spectra is related to Bohr's model of the atom. In a second experiment, students determine electron energies in the hydrogen atom.
