Experiment 4- Effect of different types of light on plant growth.

                                                             Experiment 4

AIM: To

Investigate the effect of different types of light on plant growth.
.

APPARATUS AND MATERIAL REQUIRED: 

1. 3 pots
2. 3 different types of light (e.g., fluorescent light, incandescent light, sunlight)
3. 3 different types of seeds (e.g., radish seeds, tomato seeds, bean seeds)
4. Soil
5. Water
6. Measuring tape
7. Ruler
8. Notebook and pen

Pots can be made of plastic, ceramic, or metal. They should be the appropriate size for the type of plant being grown.

OBJECTIVES:

1. To determine which type of light is most effective for plant growth.
2. To compare the growth of plants that are exposed to different types of light.
3. To identify the factors that contribute to plant growth.

PROCEDURE:

1. Fill each pot with soil.
2. Plant 10 seeds in each pot.
3. Place each pot under a different type of light.
4. Water the plants regularly.
5. Measure the height and width of each plant each week.
6. Record your observations in a notebook.

DATA ANALYSIS:

1. Plot the data on a graph.
2. Analyze the data to determine which type of light is most effective for plant growth.
3. Identify the factors that contribute to plant growth.

CONCLUSION:

The results of this experiment will vary depending on the types of light used, the type of seeds planted, and the growing conditions. However, in general, this experiment should demonstrate that light can promote plant growth. The type of light that is most effective may depend on the type of plant being grown. Other factors that can affect plant growth include the amount of sunlight, the amount of water, and the temperature.

ADDITIONAL INFORMATION:

This experiment is a great way to learn about the factors that contribute to plant growth. It can also be used to demonstrate the effects of light on plant growth.
