EXPERIMENT TO SHOW THE EFFECT OF DIFFERENT CONCENTRATION OF GLUCOSE ON POTATO STRIPS
INTRODUCTION: Molecules of liquid and gas are constantly in motion, they move randomly in all directions and bounce around in all directions and bounce around and into each other. As they move, they tend to sp...
Investigating the water potential of a potato
Osmosis is the movement of water molecules from a region of high water concentration to a low water concentration through a semi-permeable membrane. Our aim is to investigate the water potential of a potato through osmosis, by finding the diffe...
Potato and Carrot tissues
Interpretation.We investigated osmosis using potato and carrots. We wanted to identify any difference in the average % change in mass of the two tissues in concentrations of sugar.Our independent variable was sugar.Our dependant variable was % change in mass.To start off w...
Osmosis and water potential
Aim of the experiment:
Finding the water potential of potato.
Independent variable: concentration of the solution.
Dependent variable: percentage changed in weight of the potato strips.
Controlled variable: size of the potato strips, i...
Investigating the Water Potential Of Potato Cells Aims 1. To test how water potential, in a solution, affects the movement of water in and out of a cell by osmosis Prediction I predict that by increasing the water potential around the outside of the potato cell, (i.e. so that the water potential is...
My objective is to plan and conduct an experiment from which I should be able to draw a firm conclusion that will either prove or disprove any predictions I make. This essay aims to asse...

In this project, the relationship between the concentration of salt solution and the length of the potato strip that was immers...
To investigate the effects of increasing salinity on potato cell mass.
This experiment is based upon osmosis. Osmosis can be defined as the net movement of water molecules from a region with high concentration to a...
In this activity, you will learn how to build a battery from potatoes. Along the way, you will answer the following questions:
How does a battery work?
What is current?
What is voltage?
What happens when you put two batteries in series?
What happens when you...
The potato is a starchy, tuberous crop from the perennial Solanum tuberosum of the Solanaceae family . The word may refer to the plant itself as well as the edible tuber. In the region of the Andes, there are some other closely related cultivated potato species. Potatoes were introduced outside th...
Potatoes are one tuberous vegetable that is loved by children and adults. You can boil, bake, barbecue and fry potatoes. Whatever the form, potatoes are loved by people all over the world. Here are a few potato dishes for your dinner.

Look again at ‘At a Potato Digging’ by Seamus Heaney and at ‘A Sheep Fair’ by Thomas Hardy, which both deal with the theme of the hardship of rural life.
With close reference to the ways each poet uses language, compare and contrast what the speakers in the poems say about rural life. You...

Potato Batteries: Veggie power!
Data and Analysis
The battery was invented around 1800 by Alessandro Volta in Italy. It has become an indispensable part of modern life. Why are batteries so useful? Because they convert chemical energy into electrical energy. You can use this...
Which salt solution caused the sailor to die?
If the sailor drank the 40% salt water solution, then would die sooner, because the high amount of salt causes more dehydration.
