Describe the method for measuring meniscus levels (5)

Dialysis tubing attached to gunnel and filled with starch solution (control) another tubing is attached to a thistle funnel with starch and amylase solution (Experiment) placed in beakers of water over time water moves into tubing by osmosis (towards solute) = water line rises (meniscus) amylase tube will have less solute bec starch is being digested = lower meniscus
