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.

The human atom

Students will act out the role of atoms by dressing up as the atoms of designated elements. They will wear costumes with balloons representing valence electrons. The “atoms” will gain or lose valence electrons in order to achieve chemical stability. The students must then identify the charges of the ions formed.

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.

Discovering elements online

Students will work independently and in small groups to research assigned elements on the internet with sites given in advance. They will then contribute to a class database with their individual information. The database will then be made available for students to again work independently and in pairs to answer questions created from a class discussion to discover relationships about the elements.

The process of archaeology

In Prehistory, contact, and the Lost Colony, page 2.11

Archaeologists use several processes to address questions about the past. They may gather new data by conducting regional surveys to locate archaeological sites. Occasionally sites are partially or completely excavated to address specific research questions or to salvage information prior to disturbance by a development project. All data recovered are thoroughly analyzed following scientific inquiry procedures before conclusions are reached.
