Bulbs for Light Brites (100 bulbs per group preferably of only
3 colors if possible)
Student activity sheets
Decide who in your group will start with each job. The jobs
Researcher-locates the assigned atom on the periodic
table and ascertains the atomic number, atomic mass.
Calculator-Calculates the number of protons, neutrons,
and electrons in the atom.
Designer-Decides on the position and arrangement of the
parts of the atom to be constructed.
Builder-Places the bulbs in the designated positions on
the Light Brite.
Construct the first atom assigned by the teacher on the Light
Brite. The bulbs for the protons and neutrons should be grouped as
a nucleus at the center of the Light Brite board. The bulbs
representing electrons should be distributed around the nucleus
according to the accepted valence arrangement. When your group
completes construction of an atom, request that the teacher
inspect the work. Once the teacher approves the model, each
student should sketch the arrangement on the "Data Sheet".
For each of the subsequent atoms, rotate within the group so
everyone fulfills each responsibility.
