| 10969814165 | Law of conservation of matter | matter can be transformed from one type of substance into others, but it cannot be destroyed or created | 0 | |
| 10969814896 | Radioactive | emitting or relating to the emission of ionizing radiation or particles.(radioactive decay) | 1 | |
| 10969814897 | Half-life | The amount of time it takes for 50% of the atoms to give off radiation and decay | 2 | |
| 10969815944 | Acid and Base | acidic solutions: ph greater than 7 basic solutions: pH = 7 (pure water) | 3 | |
| 10969816800 | Organic compound | carbon (and hydrogen atoms joined by bonds and may include other elements) - such as nitrogen, oxygen, sulfur, and phosphorus | 4 | |
| 10969816807 | Inorganic compound | lack carbon-carbon bonds | 5 | |
| 10969817963 | Polymer | long chains of carbon molecules - the building blocks of life - three types (proteins, nucleic acids, carbohydrates) | 6 | |
| 10969818613 | Macromolecule | -large sized molecules - types: DNA, RNA, cellulose, hemoglobin, protein, nucleic acids, and carbohydrates | 7 | |
| 10969819965 | Kinetic Energy | energy of motion - thermal, light, sound, electrical, subatomic particles | 8 | |
| 10969820945 | Potential Energy | energy of position - nuclear, mechanical energy, chemical bonds - chemical energy=potential energy held in the bonds between atoms (key for biological systems) | 9 | |
| 10969824596 | First law of thermodynamics | Energy can change forms, but it cannot be created or destroyed.(conserving energy) -ex: cellular respiration - potential energy in sugar molecules is released heat during exercise - sun's energy is converted into chemical by photosynthesis - solar radiation from sun is reflected by clouds or converted into heat once it is absorbed by the earths surface - 16% of the energy from gas makes a car move, 84% is lost as heat and mechanical energy | 10 | |
| 10969825189 | Second law of thermodynamics | energy changes from a more-ordered to a less-ordered state - imputing energy from the outside the system increase order - photosynthesis uses the light dependent reactions and Calvin cycle to fuse CO2 and H2O into glucose C6H12O6 - liquid water will evaporate into gas at room temperature - while playing Jenga, the blocks will eventually find themselves scattered on the table or floor | 11 | |
| 10969825190 | Photosynthesis | the process of turning the sun's diffuse light energy into concentrated chemical energy. (Sunlight converts carbon dioxide and water into sugars) | 12 | |
| 10969826114 | Cellular Respiration | the process by which a cell uses the chemical reactivity of oxygen to split glucose into its constituent parts, water and carbon dioxide, and thereby release chemical energy that can be used to form chemical bonds or to perform other tasks within the cell (when an animal like a deer eats the leaves of a plant) | 13 | |
| 10969826115 | Chemosynthesis | uses energy vents and potential in hydrogen sulfide to produce sugar | 14 | |
| 10969826834 | Core | at earth's center is a dense core consisting mostly of iron, solid in the inner core and molten in the outer core. | 15 | |
| 10969826835 | Mantle | The layer of hot, solid material between Earth's crust and core. (elastic rock) -asthenosphere: very soft or melted rock | 16 | |
| 10969827527 | Crust - (lithosphere) | the harder rock above the asthenosphere is what we know as the lithosphere. The lithosphere includes both the uppermost mantle and the entirety of Earth's third major layer, the crust, the thin, brittle, low-density layer of rock that covers Earth's surface. | 17 | |
| 10969828393 | Plate tectonics | The theory that pieces of Earth's lithosphere are in constant motion, driven by convection currents in the mantle. | 18 | |
| 10969828805 | Divergent boundary | tectonic plates push apart from one another as magma (rock heated to a molten, liquid state) rises upward to the surface, creating new lithosphere as it cools. (Slicing across the floors of the world's oceans) | 19 | |
| 10969829321 | Convergent boundary | where two plates converge or come together, can give rise to different outcomes | 20 | |
| 10969830476 | Transform boundary | when two plates meet, might slip and grind along one another. This movement creates friction that generates earthquakes. | 21 | |
| 10969831140 | Rock cycle | rocks and minerals that comprise them are heated, melted, cooled, broken down, and reassembled in a very slow process | 22 | |
| 11158556740 | Subduction | An example of the convergant plate boundary (where plates collide) -it is when the oceanic plates slides beneath continental crust A. The Cascades, Andes Mountains B. Magma erupts through the surface in volcanoes | 23 | |
| 11158556741 | Subduction zones | places where plates are pushed down into the upper mantle - generate tsunamis when there is a sudden downward movement of crust - volcanoes are associated in these zones - they represent places on earth where rock is "recycled" to magma | 24 | |
| 11158556742 | Properties of Water | -dissolves other molecules that are vital for life -less dense ice floats on water -it is a neutral solution -water absorbs heat with only small changes in its temperature -waters strong cohesion allows transport of nutrients and waste (comes from its hydrogen bonds) -its polar nature allows it to act as a good solvent -can donate or accept h+ ions | 25 | |
| 11158556743 | Hydrogen bonds | weak attraction between a hydrogen atom and another atom - hydrogen bonds connect positive regions of 1 water molecule to negative regions of another molecule | 26 | |
| 11158556744 | Solar Radiation | Using solar radiation to produce food -autotrophs (primary producers): organisms that produce their own food --green plants, algae, Cyanobacteria- -photosynthesis: turning the sun's light energy too chemical energy | 27 | |
| 11158556745 | Polymerization | joining monomers to form a polymer -ethylene being assembled into the plastic #1, PETE -diagram monomers being linked in plant tissue to form starch molecules -creating the nucleotide backbone in the DNA structure -(PVC) is created by joining long chains of vinyl chloride together | 28 |
