Science Fair Power Point

1. Science Fair Power Point

2. 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?

3. 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.

4. 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.

5. EXPERIMENT Instructions Materials • Cut a hole in the fruit big enough for the fireworks to fit in • Slip in the fruit and firework into the fruit, then place a piece of paper inside the jar • Put the fruit and firework in the jar Make sure the wick can still be light. • Light the fruit. Pull lighter back quickly. For better results, video tape in slow mode. • After the fruit has exploded (if it did) remove the fruit and throw it out. Examine the paper • While waiting for the paper to dry, perform experiment again with another fruit • Various fruits: Lemons, Apples, Grapefruits, Kiwis, etc… • Small fireworks • Paper • A tube or Jar with a hole in the side • A lighter or box of matches • A knife to slit a hole through the fruit. Control Variables In order to control my experiment, and collect data accurately, I video taped each fruit, and weighed and measured each fruit.

6. 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.

7. Data

8. Analysis • The experiment tested my hypothesis • I know this because the papers showed how much the fruit exploded

9. 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 time • How 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?
