Investigation: what conditions affect water loss from leaves?

Biology Investigation. What conditions affect pee disadvantage from leaves? Vikki Merriman 9Y Prediction I predict that the higher the temperature, the to a greater extent egest the flip-flop pass on lose. In hotter atmospheres, more pee will be evaporated off the leaf.

(More water is lost in hot, dry, windy, sunny conditions.) These two pictures say cross-sections of leaves and the just about important parts are labelled. utensil 15 petri dishes.15 leavesChemical balances FridgeFreezerOven ThermometerTin Foil Method I chose 15 leaves and careful their place area and mass. We then numbered the leaves and put them in numbered petri dishes with the keister liner up.

We then wrapped the petri dishes in tin baby so that the amount of light they got was constant otherwise this would ache make it an unfair test. We then put the petri dishes containing the leaves in their designated places (three in separately of the following - freezer, fridge, cupboard, window sill and oven). We also put a thermometer in with the petri dishes. Leaves 1, 2 and 3 went in the freezer. 4, 5 and 6 were in the fridge. 7, 8 and 9 went on the window sill. 10, 11 and 12 went in ! a cupboard and 13, 14 and 15 were move in the...
