A scientist hypothesizes the the temperature at which an alligator's egg is incubated will determine whether the alligator will be male or female. The independent variable is

• the male alligators

• the gender of the alligator

• the temperature

• the incubator

A students was doing an experiment using the scientific method. Every three days the student plans to count the green leaves. Which would be a good hypothesis for this experiment?

• If plants are placed in direct sunlight, then they will grow more green leaves.

• If plants are places in bright light, then they will grow more green leaves than in dim light.

• If plants are place in clay pots, then they will grow more green leaves than plastic pots.

• If plants are in warmer temperatures, then they will grow more green leaves.
