RESEARCH QUESTION Always includes Dependent and Independent variable RESEARCH QUESTION Always includes Dependent and Independent variable. What is the effect of I V on DV? What is the effect of different wavelengths (IV) of light on seed germination (DV)? HYPOTHESIS: Mentions DV and IV and is a specific guess about what will happen . EX: Light Wavelengths less than 500 nm will produced the greatest number of sprouted seeds.

EX: Air isn’t hypotonic to potatoes on table. HYPERTONIC, HYPOTONIC, ISOTONIC refer to LIQUID solutions that are being compared EX: Air isn’t hypotonic to potatoes on table. 0.2 M glucose 0.5 M glucose A 0.2 M B 0.4 M Can’t say something is HYPERTONIC without saying to what. EX: Water in beaker is hypertonic to potato cells.

ADDING SOLUTE: INCREASES MOLARITY INCREASES CONCENTRATION DECREASES Ψs (more solute = more negative If in an open container this also DECREASES Ψ
