Step-by-Step Procedure

  1. 1

    Prepare pots with contaminated and clean soil.

  2. 2

    Plant seeds in both types of soil.

  3. 3

    Water plants regularly and keep them in equal light conditions.

  4. 4

    Observe and record plant growth over several weeks.

  5. 5

    Test soil quality at set intervals (e.g., pH, nutrient levels).

  6. 6

    Compare the growth and soil quality changes.

  7. 7

    Analyze which plants performed better in bioremediation.

  8. 8

    Draw conclusions based on findings.

Expected Results

It is expected that certain plants will thrive in contaminated soil and improve its quality, demonstrating their potential for bioremediation.

Variables

Independent Variable

plant species

Dependent Variable

soil quality and plant health

Controlled Variables

amount of water, light exposure, type of soil

Safety Notes

Handle contaminated soil with gloves and avoid direct contact.

Presentation Tips

  • Visualize data with graphs showing soil quality changes.

  • Include photos of plant growth stages.

  • Discuss the real-world implications of bioremediation.
