Test how fruit ripens and what makes it ripen faster or slower.

Take 3 apples and place one in the fridge, one at room temperature and one in a very warm area.  Record daily how ripe the fruit is.  Is it getting softer.  What happens to the skin.  Does it change color.  Does it smell.

Now take two piece of a fruit and put one by a window and the other in a closet and record daily the same things as above. 

Next take a very ripe banana and a green banana and place them in a paper bag and take two more green bananas and place them in another paper bag.  Record daily what happens to the bananas.  Does the banana with the extra ripe banana get riper quicker than the others.

Next take two pieces of fruit and put one in a Ziploc bag and one sitting out on a counter.  Record daily what each piece of fruit looks like and which one is ripening faster.  Check for softness, color, smell and skin.

Do different fertilizers change how a plant will grow?

Get 4 pots and put soil and the same kind of plant in each.  Put different nutrients in each pot.  The first pot put only nitrogen and the 2^nd pot only phosphorus and the third pot potassium and the 4^th pot a mixture of all three.  You can get these fertilizers from Wal-mart or a garden store.  Water each the same and make sure they get the same temperature and light.  Record how each grows.  You can record their height, width, the number of leaves, and the color of the plant.
