4th Grade Elementary Lab Report

I. Introduction

In this experiment, we will explore the basic principles of plant growth. The objective is to understand how different conditions affect the growth of a plant.

II. Materials

• Five small pots

• Soil

• Watering can

• Sunflower seeds

• Grow light

• Notebook and pen

III. Procedure

A. Initial Setup

1. Fill each pot with soil up to 2 inches below the rim.

2. Place one sunflower seed in each pot.

3. Cover the seeds lightly with soil.

4. Label each pot for different conditions (e.g., sunlight, grow light, no light).

B. Watering and Observation

1. Water each pot regularly, every other day.

2. Record the growth of the plants every three days in the notebook.

IV. Results

Day	Sunlight (cm)	Grow Light (cm)	No Light (cm)
1	0	0	0
7	3	2	0
14	6	4.5	0
21	9	7	0

V. Discussion and Conclusion

The sunflower seed planted under sunlight grew the tallest, reaching 9 cm by the end of the experiment. The seed under grow light also showed significant growth, reaching 7 cm. However, the seed kept in the dark did not grow at all. This suggests that light is a crucial factor in the growth of plants.
