For numbers 8 to 11:
Joan and her friends went to the pond to check on the frogs. To her surprise, some of the frogs had extra limbs. She and her friends were astonished and immediately observed and compared there behavior to other frogs living in the pond. Joan observed that the “abnormal” frogs have 7 legs more than those of the ordinary frogs. Her friends observed that the “abnormal” frogs have greener skin than those of the ordinary frogs. After this event, she and friends reported this phenomenon the Department of Agriculture.

10.) In the selection, which scientific method did she and her friends use?
A. formulating a problem B. inferring C. formulating a hypothesis
D. observing

B. Identify hazardous procedures and chemical before beginning
C. Read through the whole experiment before beginning
D. Not wearing an apron and goggles
For numbers 14- 19:
Gary wanted to know if the amount salt affects the position of a hard boiled egg in a beaker of water. So, he conducted an experiment which will test his hypothesis. After the experiment, he puts the results on a table. Here are the results:
Number of Trials Mass of egg (g) Amount of salt
(teaspoons) Position of the egg before the salt was put in Position of the egg after the salt was put in
1 12 grams 5 bottom bottom
2 12 grams 10 bottom middle

B. If the amount of salt is small, then the egg will sink
C. There is no significant difference in the position of the egg whether the
amount of salt varies
D. There is no significant difference in the density of egg whether the amount of
salt varies
16.) What is the best conclusion for this experiment?
A. Salt significantly affects the density of a hard boiled egg
B. Salt significantly affects the position of an egg in a beaker of water
C. Salt does not affect the density of a hard boiled egg
