Standards and Benchmarks
Michigan Curriculum Benchmarks
1. IV.1.h.2
2. IV.2.h.1
3. IV.1.h.3
National Curriculum Standards-Physical Science (9-12)
1.Knows the structure of an atom (e.g., negative electrons occupy most of the space in the atom; neutrons and positive protons make up the nucleus of the atom; protons and neutrons are almost two thousand times heavier than an electron; the electric force between the nucleus and electrons holds the atom together)
2.Understands how elements are arranged in the periodic table, and how this arrangement shows repeating patterns among elements with similar properties (e.g., numbers of protons, neutrons, and electrons; relation between atomic number and atomic mass)
3.Knows that chemical reactions can take place at vastly different rates (e.g., from the few femtoseconds required for an atom to move a fraction of a chemical bond distance to geologic times scales of billions of years) and reaction rates depend on a variety of factors that influence the frequency of collision of reactant molecules (e.g., shape and surface area of the reacting species, temperature, pressure, the presence or absence of a catalyst)
