Create a Self-Watering Plant System

Objective:

In this hands-on lab, you will design and build a self-watering system for plants that can monitor soil moisture and provide water when needed. Through this project, you will learn about resource management and problem-solving using simple mechanisms.

Materials:

• Small plant or potted seedling
• Plastic bottle (with cap)
• Thin string or cotton thread
• Potting soil
• Watering can
• Scissors
• Ruler
• Small container or tray
• Procedure:

1. Research and Background:

Begin by understanding the needs of plants in terms of water. Research how plants absorb water from the soil and how over-watering or under-watering can affect their growth.

2. Design Phase:

• Think about how you can create a system that mimics the way plants absorb water naturally.
• Consider how the string or thread can be used to transfer water from the bottle to the soil.

3. Create the Self-Watering System:

• Fill the plastic bottle with water using a watering can.
• Place the cap on the bottle.
• Use the scissors to make a small hole in the cap.
• Insert one end of the string or thread through the hole in the cap. This will act as a wick to transfer water from the bottle to the soil.

4. Plant Preparation:

• Fill a small container or tray with potting soil.
• Plant the small plant or seedling in the potting soil.
• Make sure the soil is evenly moist before proceeding.

5. Set Up the Self-Watering System:

• Place the plastic bottle upside down into the soil next to the plant.
• Insert the other end of the string or thread into the soil, making sure it touches the soil where the plant's roots are.

6. Testing:

• Observe the plant's growth over the next few days.
• Check the water level in the plastic bottle. Is it decreasing? Is the soil staying evenly moist?

7. Reflection:

• After observing the plant for a while, reflect on how well the self-watering system worked.
• Did the plant show signs of over-watering or under-watering?
• How effective was the simple mechanism of the string as a wick in transferring water?

Conclusion:

Through this lab, you've successfully created a self-watering system for plants using a simple mechanism. This project highlights the importance of resource management and problem-solving without relying on technology. By mimicking natural processes, you've provided a practical solution for maintaining plant health and growth. This experience demonstrates that even simple inventions can have a positive impact on our daily lives and the environment.
