What is my weak points.

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

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 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

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.
