Students can use the Chem Time Clock to learn the value of the elements as they plan and conduct an investigation to describe and classify different kinds of materials by their observable properties.
Students can use the Chem Time Clock to learn the value of the elements as they develop a model to describe that matter is made of particles too small to be seen.
Students can use the Chem Time Clock to remember the value of the elements as they develop models to describe the atomic composition of simple molecules and extended structures.
Substances are made from different types of atoms, which combine with one another in various ways. Atoms for molecules that range in size from two to thousands of atoms.
Students can use the Chem Time Clock to reference the Periodic Table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
The Periodic Table orders elements horizontally by the number of protons in the atom's nucleus and places those with similar chemical properties in columns. The repeating patterns of this table reflect patterns of outer electron states.
Students can use the Chem Time Clock in a fun way to reference the Periodic Table. The 24 numbers found on the face of a clock are replaced with symbols of elements having the corresponding atomic numbers. 'H' replaces '1', 'He' replaces '2', etc.
