3/31 Students were given the following questions and asked to brainstorm and research answers. We then discussed them in class:
2/28 Oxidation and reduction
2/25 Gas law explantation of crushing a soda can.
1/23/08 Discussion of ionic, covalent, and metallic bonds.
electrons in outer level
of energy levels
charge of atom
2 (in 2nd column)
1/22/08 We reviewed the trends in the families of the periodic table and whether they are metals or nonmetals.
1/21/08 We discussed the number of electrons in the outer energy level of the families and discussed whether those atoms would gain or lose electrons in order to have a filled outer energy level.
1/18/08 We discussed what happens if electrons pick up energy and the energy levels that are in the atom. energy can be given off as heat or light when the electron falls back. This is a basic idea in fireworks.
1/17/08 We used a periodic table to circle the elements used in fireworks and discuss where they seemed to be concentrated. We then discussed how a periodic table is arranged and why the properties of each column or family are the same (same number of electrons in the outer energy level). We also learned that each row or period represents an energy level in the atom.
1/16/08 Elements used in fireworks, their atomic number, number of protons and electrons (same as the atomic number), and how many electrons in each energy level. Use this information to complete the worksheet.
