Teacher Resources for Instructional Planning


HS, Chemistry Std 3.2: Calculate the number of protons, neutrons, and electrons in an isotope.

Lesson Plans: Yumminium To get students to think about the periodic table and that new elements are being discovered all the time. Students will be asked to calculate the atomic mass and number of neutrons of Yumminium. Isotopes of Pennies To demonstrate that isotopes of an element have different masses; that isotopes are atoms of the same element that have different numbers of neutrons; and that atomic mass is the weighted average of the naturally occurring isotopes of an element. The Numbers Game Find the Atomic Number, Mass Number, Proton Number, Neutron Number. and Electron Number Introducing Atoms To explore atomic structure.

Resources: Very simple worksheet on atomic changes Homemade Toothpaste THE SAME EVERYWHERE Chem-4-kids periodic table. Chemistry and Other Science Labs Tom Stretton's Chemistry Pages Great tutorials and practice problems The Periodic Table of Comic Books Associates each element with a comic reference - fun Interactive Periodic Table Created by an eighth-grade student! Chemicool Periodic Table This is an all-purpose, interactive periodic table that would be useful for high-school chemistry classes. In addition to general information about the elements, it includes the following: states, energies, oxidation and electrons, appearance and characteristics, reactions, conductivity, abundances, and more. Pyrotechnics: It's Elemental Some of the important elements that make a firework work. Chem4kids Great tutorials and activities.
