Cleaning Soil with Thlaspi Plants

Hard
Cleaning Soil with Thlaspi Plants | Science Fair Projects | STEM Projects
Let's see if we can use plants to clean up contaminated soil! We'll use Thlaspi plants to remove zinc from soil and see how much zinc is removed.

Hypothesis

The hypothesis is that the amount of zinc removed from soil by the Thlaspi plant will not be significant.

Method & Materials

You will plant Thlaspi seeds in a shallow container filled with soil that has 600ppm of zinc. You will then monitor the plants for 30 days and remove them from the soil. You will repeat this process four times and send the soil samples to a lab to test for zinc content.
You will need 400 Thlaspi seeds, 1 shallow container, soil with 600ppm zinc, and 5 small containers.

Results

Our results showed that the level of zinc content in the soil showed a small decline after every growth cycle of the Thlaspi plant. This proves that the hypothesis was correct, and that phytoremediation is a time-consuming process that is more effective in rehabilitating soil over the long term.

Why do this project?

This science project is interesting because it shows how plants can be used to clean up contaminated soil. It also shows how phytoremediation is a natural process that is environmentally friendly.

Also Consider

Variations of this project could include using spinach instead of the Thlaspi plant, or comparing the rehabilitating abilities of other types of plants in removing other types of minerals.
