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?

Acid rain can have a pH between 1.5 and 5.0. The effect of acid rain on the environment depends on the pH of the rain and the characteristics of the environment. It appears that acid rain has a negative effect on plants. The scale below shows the pH of normal rain. Provide the information requestec below that should be included in a research plan to test the effect of pH on the early growth of bean plants in the laboratory.

two seedlings that weight 5 grams are planted, each into a pot containing 3 kg of soil. Plant "A" is given 3 grams of nitrogen, phosphorus, and potassium each per year and plant "B" is not. Both plants are kept on the same green house and given the same amount of water and light. After 5 years the plants are allowed to dry completely. the soil and dried plants are weighed again. The soil from both containers weighs 2.8 kg Plant "A" has a dry mass of 6 kg Plant "B" has a dry mass of 2 kg Where Did the matter come from as the plants grew? Explain your answer
The high acidity of the soil means less capacity to bind positively charged ions. True or False?

Some seeds (tomato, for example) had been germinated and the seedling grew for 2 weeks in soil, where the soil water potential was maintained at -0.2 bars. The plants were then divided into 5 groups and each group subjected to a different soil water potential as follows: Group 1: 0 bars Group 2: -0.03 bars Group 3: -0.2 bars Group 4: -3.0 bars Group 5: -5.0 bars At the end of three weeks at these various soil water potentials, the plants that would have made the least growth would be expected in which group?
