Sugar level in plant sap at different times and dates 

All green plants make sugars. A plant's leaves contain a green substance called chlorophyll (it is this that gives plants their characteristic color). The chlorophyll uses light energy from the sun to combine carbon dioxide and water to produce sugar. The water comes from the soil via the plant's roots while the carbon dioxide comes in through tiny pores in the plant's leaves called stomata.  The by-product of this process is oxygen.

The amount of sugar in plants depends on many different factors. The most important factor is plant type. That is why certain plants such as sugar cane and sugar beet are planted just for producing sugar. In this project we will study the amount of sugar in different plants and different conditions. There are many different types of plants and many different conditions (light, temperature, amount of water, ..) that you may select for your study.

 Project description:
In this project you will perform experiments that include extraction of plant sap and using a refractometer or a hydrometer determine the amount of sugar. You can also make your own refractometer or hydrometer as a part of your experiment.
