School Project: Testing Chlorine Effects on Plants

Use Identical Small Pothos Plants for Chlorine Experiment

For a school project on chlorine’s effect on plants, use small, inexpensive, genetically identical plants. Pothos (Epipremnum aureum) in 3- or 4-inch pots are ideal:

• Low light requirement – easy to maintain consistent conditions.
• Fast, visible response to stress.
• Inexpensive and widely available.

Water each plant with different chlorine concentrations and compare growth, leaf color, and health over time. Ensure all other variables (light, temperature, pot size, soil) are identical.

If your project has a different focus, provide more details for tailored advice.
