AIM: 

Does the amount of sunlight affect the growth of a plant?
.

2. 3 pots
3. A sunny spot in your yard or garden
4. A shady spot in your yard or garden
5. Water

Plants in a sunny spot

OBJECTIVES:

To determine which amount of sunlight produces the tallest plant.

PROCEDURE:

1. Plant one plant in each pot.
2. Label each pot with the amount of sunlight that the plant will receive.
3. Place one pot in the sunny spot, one pot in the shady spot, and leave the third pot in a spot that receives medium sunlight.

CONCLUSION:

The results of this experiment suggest that sunlight can help to increase the growth of plants.

ADDITIONAL INFORMATION:

1. You can also experiment with different types of plants to see how that affects their growth.
2. Be sure to water the plants regularly so that they do not dry out.
3. This experiment can be adapted to use other factors that affect plant growth, such as water, fertilizer, or temperature.
