Physics 4e- Students know radio waves, light, and X-rays are different wavelength bands in the spectrum of electromagnetic waves whose speed in a vacuum is approximately 3 x 108 m/s (186,000 miles/second). (Focus here is on infrared and visible light spectra.)
Earth 7a- Students know the carbon cycle of photosynthesis and respiration and the nitrogen cycle.
Earth 7b- Students know the global carbon cycle: the different physical and chemical forms of carbon in the atmosphere, oceans, biomass, fossil fuels, and the movement of carbon among these reservoirs.
Earth 7c- Students know the movement of matter among reservoirs is driven by Earth’s internal and external sources of energy.
Earth 7d*- Students know the relative residence times and flow characteristics of carbon in and out of its different reservoirs.
Earth 9c- Students know the importance of water to society; the origins of California’s fresh water, and the relationship between supply and need.
Biology 6d (water cycle only)- Students know how water, carbon, and nitrogen cycle between abiotic resources and organic matter in the ecosystem and how oxygen cycles through photosynthesis and respiration.
Chemistry 5- Acids, bases and salts are three classes of compounds that form ions in water solutions.
Chemistry 5a- Students know the observable properties of acids, bases, and salt solutions.
Chemistry 5c- Students know strong acids and bases fully dissociate and weak acids and bases partially dissociate.
Unit Concept #2— The biotic systems of the Earth exist in a dynamic equilibrium. The biotic composition of the Earth has changed over time. The evolution of species and the ecosystems to which they belong occurs as a result of the Earth's constantly changing environments. The composition and stability of the Earth's ecosystems are affected by the dynamic interactions among many factors, including changes in climate and human activity. Over time, the species composition of ecosystems evolves as a result of genetic changes that occur in changing environments. A large diversity of species within an ecosystem increases the probability that at least some members will survive major environmental changes.
Biology 6- Stability in an ecosystem is a balance between competing effects.
Biology 6a- Students know biodiversity is the sum total of different kinds of organism and is affected by alterations of habitats.
