Eratosthenes determined the circumference of Earth by conducting an experiment. Put his steps in order as they correlate to the scientific method.
T
Conduct an Experiment: Measure the angle of a shadow at high noon
in Syene and Alexandria,
Make Observations: In Syene, the sun's rayfare vertical at noon. At
t the same time in Alexandria, the rays are 7.2 degrees from the
vertical
Draw Conclusions: The angle represents the amount Earth curves
11. between Syene and Alexandria. This is 1/50 of a complete circle and
1/50 of Earth's circumference.

Scientists are conducting a study on the effectiveness of a new drug on memory loss. they are giving some of the test subjects the new drug to find out if it improves their long-term memory. which are possible limitations of this study? check all that apply. a) test subjects may want to participate in additional experiments. b) test subjects may think they should be paid more. c) test subjects may get bored and want to quit early. d) test subjects may have to travel during the experiment. e) test subjects may have full-time jobs. this is multiple choice. you for the !
