Cheat Sheet
- Cell Structure and Function -
All living things are built from cells, each housing organelles like the nucleus ("control center") and mitochondria ("powerhouse") that produce energy (National Institute of General Medical Sciences). A simple mnemonic - MR. Nucleus Cooks Pies - helps you recall Membrane, Ribosomes, Nucleus, Cytoplasm, Plastids. Peeking at onion skin under a microscope can make these parts come to life!
- Photosynthesis and Its Formula -
Green plants convert sunlight into chemical energy through photosynthesis in chloroplasts, following the equation 6CO₂ + 6H₂O → C₆H₂O₆ + 6O₂ (NASA Earth Science). To remember the balanced reaction, imagine "Six carrots and six watermelons make one candy bar and six oranges!" - the numbers match the chemical coefficients perfectly. This process not only feeds the plant but also produces the oxygen we breathe.
- States of Matter and Changes -
Matter exists mainly as solids, liquids, and gases, switching forms through melting, evaporation, condensation, and sublimation (American Chemical Society). Temperature and pressure shifts shuffle particles: heat ice at 0 °C to melt, or cool steam below 100 °C to condense. Use the fun mnemonic "My Extraordinary Cat Sleeps" to recall Melting, Evaporation, Condensation, Sublimation.
- Forces, Motion, and Newton's Laws -
Newton's First Law (inertia) and Second Law (F = ma) explain why objects stay put or speed up when pushed (NASA Glenn Research Center). The formula F (newtons) = mass (kg) × acceleration (m/s²) helps calculate exactly how much force you need. Try pushing a light skateboard versus a heavy box to see firsthand how mass affects acceleration under the same force!
- The Periodic Table and Element Families -
The periodic table organizes elements by atomic number and shared traits, placing reactive alkali metals in Group 1 and stable noble gases in Group 18 (IUPAC). Vertical groups show similar chemistry - Group 1 metals fizz in water, while Group 17 halogens bond easily with metals. Remember the first four elements with "Happy Henry Likes Beans" for Hydrogen, Helium, Lithium, Beryllium.
