Plant growth
Can plants live without Oxygen?
 Introduction: During the process of photosynthesis plants use the energy from the light, water from the ground, and carbon dioxide from the air to produce sugar, starch and cellulose. The byproduct of this process is oxygen. All the oxygen in the atmosphere is actually made by plants on the ground and in the oceans.

At night however, plants absorb oxygen and release carbon dioxide.

In many places it is a common belief that you should not sleep under large trees at night, because the shortage of oxygen and excess production of carbon dioxide may suffocate you. We don't know how accurate such claims are, so we want to investigate part of such claims.

 Project description:
In this easy science project you will investigate if plants need oxygen and what happens to them in absence or shortage of oxygen. It will take you about 4 weeks to complete your experiments. All materials may be found at home or are available locally in most areas. In this project you will grow 3 groups of plants in 3 different oxygen levels and compare the growth rate. You will finally present your results with data tables, result tables and a bar graph..
