Cheat Sheet
- Newton's Laws of Motion -
Understanding Newton's three laws (inertia, F=ma, action - reaction) is a cornerstone for many science multiple choice questions in physics. For example, calculating acceleration uses F=ma, where force (F) in newtons equals mass (m) in kilograms times acceleration (a) in m/s², as detailed in MIT OpenCourseWare. Regularly practicing problem sets helps cement these principles for any physics-focused science quiz questions.
- Periodic Table Trends -
Memorize key trends - atomic radius decreases across a period, ionization energy increases, and electronegativity peaks toward fluorine - when tackling science quiz questions in chemistry. Use the mnemonic "FAN IED" (Fluorine, Affects, Negativity; Ionization Energy, Donates) to lock in order and apply examples from the IUPAC periodic table guide. Recognizing these patterns streamlines answers on elemental properties in a basic science MCQ.
- pH Scale & Acid - Base Reactions -
The pH scale (0 - 14) measures hydrogen ion concentration, with pH = - log₀[H❺]; strong acids are below 3 and strong bases above 11, a frequent topic in basic science MCQ sets. The Henderson - Hasselbalch equation (pH = pKa + log([A❻]/[HA])) helps predict buffer behavior in titration questions from ACS publications. Practice with real buffer systems, like acetic acid/acetate, to master calculations for any general science trivia questions.
- Cell Organelle Functions -
For biology items in a general science trivia questions format, it's vital to know that the nucleus houses DNA, mitochondria generate ATP, and ribosomes synthesize proteins, as outlined by the NIH. A handy mnemonic is "My Really Nice Cells" (Mitochondria, Ribosomes, Nucleus, Cytoplasm, Lysosomes) to recall primary organelles. Visual diagrams and flashcards reinforce these structures for any cell-biology science multiple choice questions.
- Photosynthesis Reaction & Light Reactions -
Elementary science multiple choice quiz items often ask for the balanced equation: 6 CO₂ + 6 H₂O → C₆H₂O₆ + 6 O₂, which summarizes the Calvin cycle and light-dependent stages. Remember that light reactions occur in thylakoid membranes to produce ATP and NADPH, while the Calvin cycle in the stroma fixes CO₂, as explained by NASA's astrobiology resources. Drawing and labeling chloroplast diagrams cements these processes for confident quiz performance.
