Title: The effect of ethylene production on the unripe banana when are stored together with pear in a bag.  Hypothesis: Ethylene is a plant hormone released as a gaseous state into the air by rapidly growing tissues and it affects the surrounding fruits. Iodine solutions bind to the starch of the plant by forming a dark complex. So the darker the fruit, the lesser the content of starch which means the fruit is unripe and vice versa. The lighter color of fruit represents a more ripening status of fruit. Variables. Independent variable: Concentration of ethylene Dependent variable: Conversion of starch into sugar (ripening of fruit). Control (describe at least 2):  A total of 8 bags will be made, Bags 1-4 will be the control group and 5-8 will be the test group. Put 1 unripe pear in each of the control bags. Seal each bag and one unripe pear and 1 banana in each of the test bags and seal them.  Place all the bags together and record the observations from the initial appearance to the…

3. Mrs. Gulliver wants to find out whether or not Miracle Grow really makes plants grow faster. She takes two identical pots, puts 1/2 cup of dirt into each one. Puts 3 pea plant seeds in each one, and tops each off with 1/2 cup more dirt. She waters the plants the same amount at the same time each day. The only differences is that one plant is watered with regular water, while the other is watered with water that has Miracle Grow in it. Indenpendent variable: Dependent Variable: Control Variable: Constant(s): Hypothesis:
