dry using different types of liquids to grow plants.. it's sorta like the classic growing bean sprout thing.. but instead, let the experimental group use different types of liquid such as soda, vinegar, soap, etc etc, and see what happens.. note the approximate pH of each types of liquid u use.. and see how the bean sprout react to it..
OR, you can get some plants, and for the control, find the most neutral soil u can find.. and water the plant with distilled water.. and then do more basic soil, water it w/ acidic water, distilled water, and basic water.. and also acidic soil, and do the same.. see how the plants grow.. say u've noticed how with air pollution causing our rain water to be so acidic, how can our plants still survive on this mildly acidic rain? |
