Clamp and stand for holding burette Ripe, half ripe and unripe oranges Juicer optional Although reagents and glassware can be obtained from a lab supply house, hopefully students can borrow these from their schools. Distilled water is available in large grocers or from your school lab.

This banana experiment meets both of those criteria. We wanted to find out which banana would ripen first. Then, we talked about what makes bananas and other fruit ripen in the first place.

Which Will Ripen First? The green bananas happened to be sitting next to the really ripe bananas we already had. Needless to say they were no longer green… I had to go to the store 3 more times before I found the somewhat green ones we ended up using.

This is your control group — your basis for comparison. Do not close the plastic baggies. Store the baggies in different locations that have the same environment put them in the 4 corners of your bedroom away from light.

Check on the bananas once a day and observe any changes. Which one starts to ripen first? After 8 total days, our bananas looked like this. On Day 7, there was actually a bigger difference in the bananas. The banana alone still had very little brown on it.

The stem is still quite green. The Science Behind It Fruits and vegetables produce ethylene gas which among other things causes fruits to ripen. Fruit that is already ripe releases more ethylene than fruit that is not ripe. As bananas ripen, they turn from green to yellow, the peel softens, and the fruit becomes sweeter.

The soft peel is prone to bruising. When exposed to oxygen, the bruised peeled will turn brown. The apple, lime, and orange give off ethylene gas which causes the banana to ripen. We left the baggie open so oxygen could get in and turn the banana brown.

Of the 3 types of fruit we used, apples are give off the most ethylene gas. Limes and oranges release a very small amount of ethylene.

So our bananas had an effect on the lime and orange as well. Build a Lemon Battery sponsored post — How many lemons does it take to build a battery?

Can you use other fruit, too?In this experiment, the effect of light on the ripening of a banana is observed. One banana should be wrapped in a black bag and placed in a dark cupboard to ensure that no light can reach it. The other should be kept under a lamp, but not so close that the heat of the lamp has any effect on it.

of green. After day 7 they were each at a completely different ripening stage. Extreme heat- most ripe. No air-least ripe-Bananas under warmer temperatures will ripen faster-No air will release the least ethylene gas, making the banana ripen slower-Keeping bananas apart from each other will cause them to ripen slower.

Ripening can be accelerated or decelerated depending on the conditions green fruits are put under for example washing fruits or wrapping them in newspaper. Therefore newspaper (wrapping green fruit in newspaper) is the independent variable while ripening is the dependent variable.

Research fruits and their ripening stages, follow and document the different stages. Analyze what causes fruit to /5(16). Fruit ripening is affected by whether or not the fruit remains attached to the parent plant. Ethylene is produced in response to removing the fruit from its parent.

You can design an experiment to determine whether fruit ripens more quickly on or off the plant.
