Observation: I want to know what effect salt has on the growth of grass. So I measure out 3 equal-sized squares of grass out the back of the Green Building. The first square of lawn I water with 5 liters of pure water from a watering can every day. The second square of lawn I water with 5 liters of pure water with 2 grams of salt mixed in, every day. The third square of lawn I water with 5 liters of pure water with 4 grams of salt mixed in, every day. I measure the height of the grass after 14 days and note the following observations. The first square is green and 15 cm high. The second square is greeny-yellow and 6 cm high. The third square is yellowy-brown and looks dead and is only 2cm high. What could we infer about the effect salt has on the growth of grass?
