Base your answers to questions 15- 20 on the following paragraph. In a science experiment, 10 bean seedlings were placed in the dark and another 10 bean seedlings were placed in sunlight. All other growth conditions were kept the same for both sets of seedlings. After one week, it was observed that the seedlings in the dark were white with long slender stems. The seedlings in the sunlight were green and healthy.

15. The independent variable in this experiment was the _____________________

(a) number of seedlings  

(b) amount of light   

(c) temperature   

(d) size of the seedlings

16. The growth conditions that were kept the same are called the _____________________

(a) constants  

(b) predictions   

(c) observations   

(d) independent variable

17. The problem for this experiment is ____________________________________

(a) Will the amount of light effect the growth of seedlings.  

(b) Will the amount of seedlings effect their growth?   

(c) Will the amount of light effect the growth of seedlings?   

(d) Will the temperature of the air effect the growth of seedlings

18. The conclusion for this experiment is ____________________________________

(a) The seedlings grew slower in the light  

(b) Darkness did not effect the growth of the seedlings.   

(c) Light is necessary for the normal growth of seedlings   

(d) Light does not effect plant growth

19. The constants for this experiment are ____________________________________

(a) number of seedlings, type and size of seedlings, sunlight.  

(b) number of seedlings, type of seedlings, darkness   

(c) number of seedlings, type and size of seedlings, amount of water   

(d) number of seedlings, type and size of seedlings, sunlight

20. The scientist conducting this experiment should____________________________________
