Problematic:
which factor is most important for plant growth: sunlight, water, or good quality soil.
hypothesis :
water is the most important factor, then sunlight, then soil.
Materials: 8 pots, 1 bag of sand,, 1 bag of potting soil, 2 packets of seeds, , 1 measuring cup, 1 ruler, and 1 moisture meter.

Methods/Materials

We planted ten seeds in each pot, four in sand and four in good soil. We labeled each pot with a letter from A to H. Each letter has a different combination of the amount of water, the amount of sunlight, and the quality of the soil that they^Ore in. We put the plants that had high amounts of light in a window, and the plants that had low amounts of light in a closet. We decided that, on the moisture meter, the plants with low amounts of water should be about a 2, and the plants with high amounts of water should be about a 9, and we watered accordingly. Once the plants started growing, we began to record what day they sprouted, how many stalks were in the pot, how many leaves were on each stalk, how tall each plant is, what color it is, and how healthy it looks. After one month, we judged the plants on their height, the number of stalks in the pot, the number of leaves on each stalk, their color, and their health, and then compared that to our hypothesis.
Observation:
The plants in the shade grew quickest, but weren't as strong. The plants in the sunlight took longer to grow, but were much healthier.
Conclusion
We thought that water was the most important factor in plant growth, but based on our rankings, we decided that sunlight is the most important factor.

Hope this can help you https://3andlib.xplainer.net/images/smilies/wink.gif

thank u
merci

i'm so sorry for the late
i can't write it now but i promise you that i will soon

it's about detecting the presence of starch in bread



sorry again

ok
i'm waiting u

This is my project

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 does 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
