Study Notes
Scientific Method
- Definition: A series of steps scientists use to answer questions about the world.
- Steps vary: Specific steps and their order depend on the experiment and discipline.
- Key steps: Question, background research, hypothesis, experiment, data analysis, conclusion
Experimental Design
- Purpose: A process to gather data supporting or refuting a hypothesis.
- Steps: Defining variables, forming hypotheses, designing the experiment, assigning subjects, measuring the dependent variable.
- Importance: Thorough research and clear implementation of the five steps are critical.
Scientific Vocabulary and Learning Styles
- Language origins: Greek and Latin foundation of scientific terminology.
- Word parts: Prefixes, roots, and suffixes help understand complex terms.
- Learning styles: Auditory, visual, hands-on, holistic, and analytic learning are valuable.
Branches of Science
- Physics: Studies matter and energy, encompassing engineering, mechanics, heat, light, and sound.
- Chemistry: Examines molecular properties and reactions, crucial in various products and processes.
- Biology: Studies life, from molecular (DNA) to ecological (interactions) levels.
- Earth Science: Focuses on geological processes (earthquakes, volcanoes, tsunamis), oceanography, and meteorology.
- Astronomy: Explores outer space, celestial bodies, and their behaviors.
Scientific Root Words
- A list of root words and their definitions is provided.
Matter
- Definition: Anything with mass and volume.
- Types: Pure substances (elements and compounds) and mixtures.
- Properties: Physical (color, mass, density) and chemical (pH, reactivity, corrosion).
States of Matter
- Four States: Solid, liquid, gas, and plasma (differing in energy, density, volume, and shape).
- Transitions: Matter can change between phases (e.g., melting, freezing, evaporation, condensation, sublimation).
Atoms
- Definition: Smallest unit of an element retaining element properties.
- Structure: Protons (positive charge, in nucleus), neutrons (no charge, in nucleus), electrons (negative charge, orbit nucleus).
- Atomic number: Number of protons, defining an element.
- Mass number: Sum of protons & neutrons.
- Isotopes: Atoms of same element with different neutron counts.
The Periodic Table
- Organization: Arranges elements by atomic number (number of protons).
- History: Johann Dobereiner, John Newlands, Dmitri Mendeleev and Henry Moseley's contributions to its development.
- Arrangement: Periods (horizontal) & groups (vertical).
- Categories of elements: Metals, nonmetals, and metalloids.
- Periodic Trends: Used to predict properties of elements (valence electrons, atomic radius, electronegativity).
Molecules and Compounds
- Molecules: Formed from atoms, via sharing or transferring electrons.
- Compounds: Formed from two or more different elements chemically combined.
- Interconnections: Atoms are the fundamental units of molecules, elements, and compounds.
Endocytosis and Exocytosis
- Endocytosis: Cell intake of molecules/particles via membrane folding.
- Types: Phagocytosis (large substances), pinocytosis (liquids), receptor-mediated endocytosis, and caveolae (nonspecific).
- Exocytosis: Cell release of substances via vesicle fusion with membrane.
Photosynthesis
- Process: Light energy converted into chemical energy (glucose) in chloroplasts.
- Light-dependent reaction: Water and sunlight produce ATP and NADPH.
- Calvin cycle: Carbon dioxide used to synthesize glucose.
- Chloroplast structure: Thylakoids, stroma, chlorophyll, and other critical components.
Plant Cells
- Vacuoles: Water storage, waste disposal, and maintaining turgor pressure.
- Cell walls: Cellulose, providing strength and support, aiding in turgor pressure regulation.
- Turgor pressure: Pressure exerted by fluid within the central vacuole against the cell wall.
Prokaryotes vs. Eukaryotes
- Prokaryotes: Cells without nucleus or membrane-bound organelles (bacteria, archaea).
- Eukaryotes: Cells with nucleus and membrane-bound organelles (plants, animals, fungi).
- Key differences: Size, complexity, DNA structure, ribosome type.
