Alison’s experiment
Inquiry skills: IN1A6b IN1B6b IN1C6a IN1D6a
Alison wanted to do a study to see if the amount of sunlight she provides to her plants affects the
height of their growth. She planted three Sunflower seeds and placed one in the full sunlight,
one in partial sunlight and one in little sunlight. She took height measurements on the same day
for three separate weeks.
A. The full sunlight plant was 1 cm tall on week #1, 6 cm tall on week #2, and 14 cm tall on
week #3.
B. The partial sunlight plant was 1 cm tall on week #1, 2 cm tall on week #2, and 3 cm on
week #3.
C. The little sunlight plant was 1 cm tall on week #1, 1 cm tall on week #2, and 1 cm tall on
week#3.
