Physical Sciences Molecules
Share electrons Bigger atoms pull electrons
closer, polarize (+, -) Between Nonmetals
Ions Give and take electrons Cations take electrons (claw)
electrons away from other atoms, making them -.
Anions give electrons (add) electrons. Making them +.
Metals and nonmetals
Physical Sciences Describe the identifiable properties of
substances (color, hardness, conductivity, density, concentration, and ductility). Explain how changes in these properties can occur with out changing the chemical nature of the substance. Physical Change Chemical Change
Physical Sciences Atomic Number
Top number 79 The number of protons
Symbol Latin, Name, Place, People.
Atomic Weight Big number at bottom.
Average of all the isotopes. Atomic Mass Isotopes
Same element, different number of neutrons
Physical Sciences
Demonstrate that energy can be considered to be either kinetic (motion) or potential (stored). Potential energy Kinetic energy http://www.visionlearning.com/library/flash_v

Life Science Eukaryotic Cell
Has cell membrane Allows material to enter and
leave the cell. Nucleus-contains DNA Mitochondria-energy is stored
and used, contains DNA ER- transportation system within
the cell Ribosomes- protein is made Vacuoles- closets, store stuff
Life Science
Cell Wall Function is
protection, support, structure.
Chloroplasts Contain chlorophyll Make the plant
green Function is to
produce food
Earth and Space Sciences
Explain how evidence from stars and other celestial objects provide information about the process that causes changes in the composition and scale of the physical universe.http://resources.schoolscience.co.uk/PPARC

Earth and Space Sciences Explain that many processes occur in patterns within
the Earth’s systems. http://oceancurrents.rsmas.miami.edu/atlantic/atlantic.html http://serc.carleton.edu/NAGTWorkshops/structure/visualiza

Earth and Space Sciences
Explain the 4.5 billion-year-history of Earth and the 4 billion-year-history of life on Earth based on observable scientific evidence in the geologic period.http://

Law of Superposition
Earth and Space Sciences
Describe the finite nature of Earth’s resources and those human activities that can conserve or deplete Earth’s resources.
Earth and Space Sciences
Explain the process that move and shape Earth’s surfaces.http://phet.colorado.edu/simulations/index.php

Earth and Space Sciences
Summarize the historical development of scientific theories and ideas, and describe emerging issues in the study of Earth and space sciences.http://www.seasky.org/spacexp/sky5d.html
Life Sciences
Explain that cells are the basic unit of structures and function of living organisms, that once life originated all cells come from pre-existing cells, and that there are a variety of cell types.
Basic units of life We have evolved from
single-celled organisms Different cells have
different jobs.
Life Sciences
Explain the structure and function of ecosystems and relate how ecosystems change over time.Biotic- living components of an ecosystemAbiotic-nonliving components of an
ecosystem
Life Sciences
Describe a foundation of biological evolution as the change in gene frequency of a population over time. Natural Selection- Charles Darwin “Origin of Species”-
survival of fittest Offspring are more likely to survive due to
Genetic, traits, genes, alleles, mutations Ability to reproduce Ability to move Ability to attract a mate Ability to support family Ability to get food Genetics that allow you to grow
Life Sciences
Summarize the historical development of scientific theories and ideas, and describe emerging ideas.
Life Sciences
Explain how natural selection and other evolutionary mechanisms account for the unity and diversity of past and present life forms.Natural selection determines the survival of
the fittest Separates organisms to create diversity in our
world.
