SC.8.P.8.7 Explore the scientific theory of atoms (also known as atomic theory) by recognizing that atoms are the smallest unit of an element and are composed of sub-atomic particles (electrons surrounding a nucleus containing protons and neutrons). SC.7.N.3.2 Identify the benefits and limitations of the use of scientific models. SC.8.N.3.2 Explain why theories may be modified but are rarely discarded. SC.8.E.5.10 Assess how technology is essential to science for such purposes as access to outer space and other remote locations, sample collection, measurement, data collection and storage, computation, and communication of information.
Advanced: SC.912.P.8.4 Explore the scientific theory of atoms (also known as atomic theory) by describing the structure of atoms in terms of protons, neutrons and electrons, and differentiate among these particles in terms of their mass, electrical charges and locations within the atom.
SC.8.P.8.6 Recognize that elements are grouped in the periodic table according to similarities of their properties. SC.6.N.2.2 Explain that scientific knowledge is durable because it is open to change as new evidence or interpretations are encountered.
Advanced: SC.912.P.8.5 Relate properties of atoms and their position in the periodic table to the arrangement of their electrons.
Learning Targets and Learning Criteria
Students will: • recognize that atoms are the smallest unit of an element • recognize that atoms are composed of subatomic particles: o Electrons o Neutrons o Protons • create a model or diagram of an atom (nucleus and subatomic particles) o discuss the benefits and limitations of various atomic models o NOS Focus- benefits and limitations of models • explain that theories may be modified based on new evidence, but are rarely discarded (in the context of atomic theory) o NOS Focus- Scientific Theories; Technology is essential to science
Students will: • recognize that elements are grouped in the periodic table according to similar properties • predict properties of an element using a periodic table when given information about other elements in the same column o NOS Focus- Science is open to change with new evidence
Advanced: 1. Use the periodic table and electron configuration to determine an element’s number of valence electrons and its chemical and physical properties 2. Explain how chemical properties depend almost entirely on the configuration of the outer electron shell
