Potato+Wiki

Dear 2E4 students,

I hope you learnt a lot from the egg wiki. Let us try to apply what we have learnt to a new situation: potatoes!

Rectangular pieces of potato, of the same length and width, are immersed in solutions of different concentrations, 0% sugar (tap water), 5% sugar, 10% sugar and 40% sugar.

1. What did you observe about the potato strips after soaking for 40 min?


 * Concentration || Initial length/mm || Final length/mm || % change in length = (final-inital length)/original length X 100% ||  ||
 * 0% sugar ||  ||   ||   ||   ||
 * 5% ||  ||   ||   ||   ||
 * 10% ||  ||   ||   ||   ||
 * 40% ||  ||   ||   ||   ||

2. How do you explain your observations?
