                                                             Experiment 13

AIM: 

To determine the effect of different types of soil on plant growth.
.

APPARATUS AND MATERIAL REQUIRED: 

• Three different types of soil (e.g., potting mix, garden soil, sand)
• Three identical pots
• Seeds
• Water
• Measuring tape
• Graph paper

Plant in soil

OBJECTIVES:

• To identify the different types of soil.
• To measure the growth of plants in different types of soil.
• To determine which type of soil is most effective in promoting plant growth.

PROCEDURE:

• Fill each pot with a different type of soil.
• Plant one seed in each pot.
• Water each pot equally.
• Place the pots in a sunny spot.
• Measure the height of each plant every day for two weeks.
• Plot the data on a graph.

EXPECTED RESULTS:

• You can use different types of plants in this experiment.
• You can vary the amount of water that you give each plant.
• You can conduct this experiment over a longer period of time.

CONCLUSION:

The graph will show that the plant that grew in the most fertile soil grew the tallest. This experiment demonstrates that soil quality is important for plant growth.

ADDITIONAL INFORMATION:

• Be careful when handling soil. It can be dirty and can contain harmful bacteria.
• Wash your hands thoroughly after handling soil.
• Do not eat or drink anything while you are working with soil.
• Keep soil out of the reach of children and pets.
