Introduction:The objective throughout the semipermeable membrane experiment was to test the permeability of the caterpillar's intestine. Through this experiment one would be able to observe a transverse of small molecules through the cell membrane.
Question: Were starch and Lugol’s molecules able to cross the membrane?
Hypothesis: If there is a presence of glucose among the fluids in between the intestine and circulatory system then there is to be a breakdown of starch molecules within the digestive tract .
Materials: One small beaker, Two large beakers, Dialysis tubing, Plastic pipettes, Amylase, Cooked starch, Lugol’s solution, Glucose test strips, Tubing clamps
Procedure: Once in groups and materials are obtained one is to place four full
