effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away from 7 which would be the regular pH level of water. We measured the
