Study Notes
Atomic Structure and Properties
- Draw the structure of an atom, including proton, neutron, electron locations and shells.
- Use the periodic table to identify atomic number, atomic mass, and element symbol.
- Know the properties of acids and bases, and identify indicators.
Acids and Bases
- Bases: Taste bitter, feel soapy/slippery, contain hydroxide ions (OH⁻).
- Acids: Taste sour, corrosive, contain hydrogen ions (H⁺).
Chemical Reactions
- Write word equations for simple chemical reactions, identifying reactants and products.
- Understand conservation of mass (matter is neither created nor destroyed).
- Distinguish between exothermic and endothermic reactions (energy release vs. absorption).
- Identify combustion reactions (hydrocarbon + oxygen → carbon dioxide + water).
- Identify metal oxidation (metal + oxygen → metal oxide).
Chemical Equations and Reactions
- Write word equations for chemical reactions, including acid-carbonate, acid-metal, acid-base reactions.
Biological Processes
- Photosynthesis: Water + carbon dioxide + energy → sugar + water
- Respiration: Oxygen + glucose → carbon dioxide + water + energy
- Understand the link between photosynthesis and respiration.
Systems and Processes
- Identify products and types of radioactive decay.
- Compare the nervous and endocrine systems.
- Understand the reflex arc and feedback loops.
Biological Systems
- Know the peripheral nervous system (PNS) and central nervous system (CNS).
- Know the organs of the excretory/urinary and respiratory systems.
- Understand how the nervous and endocrine systems regulate body temperature.
- Understand half-life graphs.
