We collect rain water and wanted to use either our dish washer or laundry water for plants. We didn’t know what to start with or if one or the other was better. We decided to make an experiment to test those two options with tap water as the control.
You chose a very important environmental topic! Reusing grey water safely is something many communities care about, and your experiment helps explore that. I liked how you included a control group and tracked your plants over multiple days. Your observations clearly showed differences between the detergent types, and you even suggested future improvements, that’s exactly what scientists do. Keep exploring ways to protect our water resources. Brilliantly done!
I enjoyed your project because it connects to a real-life problem and saving water. You did a nice job setting up three kinds of water and taking pictures and notes over many days. I also liked your interpretation and your next step ideas, like testing other detergents and controlling the amount of soap. Great work investigating grey water and plants!
