Experiment 1: a student tested to see if sunflower growth was affected by the hardness of the soil. she used control and experimental groups. she repeated her experiment several times, and each time found that the hardness of the soil did not affect the growth. experiment 2: a student tested to see if the temperature of water affected the growth of cacti. she used control and experimental groups. her data supported her hypothesis. which experiment most likely has greater reliability, and why?

Design an experiment to test the effect of aeration on the growth of roots of bean seedlings. in your answer, be sure to: • state one hypothesis the experiment would test • describe how the control group will be treated differently from the experimental group • identify the dependent variable in the experiment • state one reason why many setups should be used in both the experimental and control groups • state one reason why several different kinds of seedlings were not tested in this experiment

Read the descriptions of two experiments below. experiment 1: a student did a test to see if the hardness of the soil affects the growth of sunflowers. she used a control group and experimental groups. she repeated her experiment several times and found each time that the hardness of the soil did not affect the growth. experiment 2: a student did a test to see if the temperature of water affects the growth of cacti. she used a control group and experimental groups. her data supported her hypothesis. which experiment is more likely to be reliable, and why? a. experiment 2, because its results supported the hypothesis b. experiment 1, because it gave the same results every time c. experiment 1, because it disproved the hypothesis d. experiment 2, because its setup included a control group

Experiment 2: a student tested to see if a new fertilizer made roses bloom earlier. she used a logical method and control and experimental groups. she performed one experiment and found that the fertilizer had no effect. which experiment most likely has greater reliability, and why? d a. number 2, because it has control and experimental groups o b. number 1, because the experiment was repeated with the same results - c. number 2, because she performed only one experiment o d. number 1, because the experiment proved the hypothesis
