INTEGRATED SCIENCE- LEVEL 1 PROPOSED INSTRUCTIONAL SEQUENCE
COURSE CONCEPT—The science curriculum in the first year of integrated science emphasizes how Earth is a unique system that supports life. Earth's biotic and abiotic systems are defined by the interaction of matter and energy through dynamic processes. These processes impact the biosphere over time. The standards in Integrated Science 1 present the foundations of physics, chemistry, biology, and earth science. These standards build the knowledge base that prepares the student for the next three years of integrated science where the rest of the California Science Standards will be addressed. The Integrated Science 1 concepts will be further enhanced by having students perform careful scientific investigations.
Semester 1—The interaction of matter and energy define the Earth's systems The periodicity of elements is a method of organizing the components of matter. This periodicity allows scientists to predict and/or demonstrate how chemicals will react when combined together with the absorption or release of energy. Following from an understanding of atomic structure and interaction, the ideas of electromagnetism and wave mechanics are introduced. The vibration of electrons gives rise to the entire electromagnetic spectrum. The movement of the electrons is the foundation of electricity and magnetism. The same principles of wave mechanics in electromagnetic waves hold true for those waves that are mechanical in nature. The earthquakes in California are a result of the motion of large plates of land and emit waves and energy that are responsible for natural hazards. A knowledge of atomic and molecular structure will provide understanding of the chemical and physical characteristics of rocks that comprise the lithosphere.
Unit Concept #1—The characteristics of matter are defined by its composition and structure. A key component to earth’s systems is the structure and composition of matter. The investigation of atomic behavior through the study of the Periodic Table will provide the foundation to understand various topics in earth science. The physical and chemical properties of rocks is determined by the atomic make up of the matter. The formation and composition of molecules determines the characteristics of matter. With this knowledge, the study of California geology and how it is shaped by plates, in the earth, will be investigated.
Chemistry1- The Periodic Table displays the elements in increasing atomic number and shows how periodicity of the physical and chemical properties of the elements relates to atomic structure.
Chemistry 1a- Students know how to relate the position of an element in the Periodic Table to its atomic number and atomic mass.
Chemistry 1b- Students know how to use the Periodic Table to identify metals, semimetals, non-metals, and halogens.
