SCIENCE FAIR POWER POINT

BIG QUESTION

Which fruit has the strongest fiber-strength?

If I were to put a fire-cracker in a fruit, how well would it hold out?

Which fruit would hold out best?

Why?

HYPOTHESIS

I think the apple has the strongest fiber strength of all the fruits because when you bite into it, it’s harder to get through it then it is a lemon. The kiwi I think has the lowest fiber strength.

INTERESTING FACTS Bananas were introduced to the American public in

1876 at the Philadelphia Centennial Exhibition. Bananas are one of the best sources of potassium. Eating an apple is a more reliable method of staying

awake than consuming a cup of coffee. Watermelon is 92% water, cabbage is 90%. Pumpkins are not a vegetable, they are a fruit. So are

avocados. Tomatoes were once considered a type of apple by

France and Italy. Tomatoes used to be yellow, not orange or red. A stalk of celery only contains 10 calories, so eating it

makes you lose weight.

EXPERIMENT

Materials

A) Various fruits: Lemons, Apples, Grapefruits, Kiwis, etc…

B) Small fireworksC) PaperD) A tube or Jar with a hole in

the sideE) A lighter or box of matchesF) A knife to slit a hole through

the fruit.

Instructions

A) Cut a hole in the fruit big enough for the fireworks to fit in

B) Slip in the fruit and firework into the fruit, then place a piece of paper inside the jar

C) Put the fruit and firework in the jar Make sure the wick can still be light.

D) Light the fruit. Pull lighter back quickly. For better results, video tape in slow mode.

E) After the fruit has exploded (if it did) remove the fruit and throw it out. Examine the paper

F) While waiting for the paper to dry, perform experiment again with another fruit

Control Variables

In order to control my experiment, and collect data accurately, I video taped each fruit, and weighed and measured each fruit.

OBSERVATIONS FROM EXPERIMENTS

If the fruit had a shell, like the grapefruit and orange, they split where the firework was placed, or didn’t explode at all, but if you opened it, you could see it had obsorbed the firework.

Fragile fruits, such as the kiwi and lemon, were quicker to explode.

Hard fruits, such as pears and apples, split and separated in pieces.

DATA

Fruit Volume Density

Banana 14.432 in³ .346 oz/ in³

Kiwi 3.451 in³ 0.426 oz/ in³

Grapefruit 1.995 in³ .456 oz/ in³

Apple 15.979 in³ . 469 oz/ in³

Pear 9.471 in³ .6335 oz/ in³

Lemon 1.6915 in³ .796 oz/ in³

ANALYSIS

The experiment tested my hypothesis I know this because the papers showed how

much the fruit exploded

CONCLUSION

My hypothesis was wrong, but the apple came close to being the strongest.

I wouldn’t have changed anything in my experiment.

Questions I have for next timeHow well would an egg survive if I preformed this

experiment on it? Does having a peel around a fruit affect its strength? Would using a different set of fireworks affect the

outcome?
