Iodine clock: estimating hydrogen peroxide concentration by serial dilution
Serially dilute a 2.0% hydrogen peroxide stock by half, four times, then time how long each dilution takes to turn a starch–iodide–thiosulfate mixture blue-black. Use the same timing method on an unknown 'patient sample' to estimate its hydrogen peroxide concentration by interpolation.
Microscopy and stereology: a plant stem cross-section (slide J1)
A fixed, confidential, pre-mounted stem section — not one you prepare yourself. Draw a large low-power plan (labelling the xylem) and a high-power group of four epidermal cells (labelling the waxy cuticle), compare the slide against a printed photomicrograph of a different stem, then use a sector count and a known angle to estimate the section's vascular-bundle density.
