Objective
Investigate how plastic waste affects soil quality and plant growth.
Materials
- Potted plants (same species)
- Plastic waste (e.g., plastic bags, plastic bottles)
- Soil
- Measuring tape or ruler
- Notebook for observations
Instructions
- Prepare several pots with soil, and embed different types and amounts of plastic waste in some pots.
- Plant seeds or seedlings of the same species in each pot.
- Water the plants equally and monitor their growth over several weeks.
- Measure the height and health of each plant weekly using a measuring tape or ruler.
- Record your observations in a notebook, noting any differences in growth between the plants in plastic-infused soil and those in regular soil.
- Analyze your findings to understand the effect of plastic waste on soil health and plant growth.
