1. What is my weak points.

2. 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

3. Physical Sciences

4. 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

5. 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

6. 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 iewer.php?oid=1429&mid=46 http://www.visionlearning.com/library/flash_v iewer.php?oid=1429&mid=46

7. 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

8. Life Science Cell Wall Function is protection, support, structure. Chloroplasts Contain chlorophyll Make the plant green Function is to produce food

9. 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 /bang/bang.htm http://resources.schoolscience.co.uk/PPARC /bang/bang.htm

10. 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/visualizat ions/orogeny.html http://serc.carleton.edu/NAGTWorkshops/structure/visualizat ions/orogeny.html http://oceanservice.noaa.gov/education/pd/oceans_weather _climate/welcome.html http://oceanservice.noaa.gov/education/pd/oceans_weather _climate/welcome.html

11. 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://phet.colorado.edu/simulations/index.ph p?cat=Earth_Science http://phet.colorado.edu/simulations/index.ph p?cat=Earth_Science Law of Superposition

12. Earth and Space Sciences Describe the finite nature of Earth’s resources and those human activities that can conserve or deplete Earth’s resources.

13. Earth and Space Sciences Explain the process that move and shape Earth’s surfaces. http://phet.colorado.edu/simulations/index.php ?cat=Earth_Science http://phet.colorado.edu/simulations/index.php ?cat=Earth_Science http://serc.carleton.edu/NAGTWorkshops/struc ture/visualizations/orogeny.html http://serc.carleton.edu/NAGTWorkshops/struc ture/visualizations/orogeny.html

14. 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

15. 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.

16. Life Sciences Explain the structure and function of ecosystems and relate how ecosystems change over time. Biotic- living components of an ecosystem Abiotic-nonliving components of an ecosystem

17. 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

18. Life Sciences Summarize the historical development of scientific theories and ideas, and describe emerging ideas.

19. 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.
