A student formed the hypothesis "If corn seeds were planted in freezing temperatures, then they would not germinate (grow)". 20 grains of corn were
planted on moist filter paper in each 2 petri dishes. The dishes were covered with
black paper to exclude light. Dish #1 was kept at 0 C (freezing) and dish #2 at 25
C. After 10 days, no seeds in dish #1 had germinated; 18 seeds in dish #2 had
germinated by the end of the fifth day.
The student
O only needed dish #2 to support his hypothesis
supported his hypothesis
did NOT support his hypothesis
needed only dish #1 to support his hypothesis
