The process of photosynthesis prove the presence of starch in the green plants
Introduction
Plants are considered one of the most important factors to maintain the environmental balance and we can be aware of this fact through a simple comparison
Experiment requirements;
-plant of giranyum(green color)
-a light source
-black cover
-three basins
the first basin :boiling water
the second: basin alcohol
the third basin :water iodine
-the source of heat
-hour electronic
-plate glass
Prepare samples;
we take the giranyum and put it in a pot three leaves from the plant
the first leaf;completely exposed to light
the second leaf;completely covered with black cloth
the third leaf;partially covered with black cloth
Experience step
1-the three leaves are then put in the first basin of water boiling
2-then the leaves are transported to the second basin of alcohol and let them for 10 minutes
3-then we put them in the third basin of water iodine for half an hour
4-get out of the basin the three leaves and clean them with water
Note the results of the experiment:
After cleaning the leaves with water we put them over the glass and we observe them,we note:
1-the emergence of blue-purple spots on the surface of the first leaf which was completely exposed to light
2-the emergence of non-blue-purple spots on the surface of the second leaf which was completely covered with black cloth
3-the emergence of blue-purple on half of the leaf exposed to light and doed not appear in the other half which was covered with black cover
Conclusion of the experiment:
Through the results we can say that the plant at light can install its own organic materials such as starch this process called photosynthesis and requires the presence of chlorophyll,light,carbon dioxide(co2),water and mineral salts
[Conclusion:
[]Through this scientific experiment we know that the process of photosynthesis is one of the most important biological process on the surface of the globe this process needs all the necessary condition provided in the external and internal environment of the plant so that the process of photosynthesis occurs

The experience
How we can search about existence of the Nicotine in cigarettes:
The Instruments:
Ø Plastic Bottle
Ø Cotton
Ø Cigarette
Ø Sulfur
The Hypotheses
We can do that by a simple experience and by using that simple
Instruments
The experience
We close the head of the bottle by the cotton then we burn the cigarette in the head of the bottle (WP the cotton), then we press the bottle in order to bun the cigarette; here we observe that the cotton is colored by ye how color that substance is called «Nicotine».

The Final Results
1- When we bean one cigarette cotton’s color changes to ye how.
2- The cigarettes are very dangerous for the health of mankind because it contain poison «Nicotine».
