Today in Science, we had to do an expirement on which way a piece of jellied toast falls. Basically, My Science teacher dropped a piece of toast and it fell jelly side down and she wanted to know why it fell jelly side down. Below is the Lab Report.
Jelly Side Up
Introduction:
The purpose of this experiment was to see if jellied toast fell jelly side down all of the time. If jellied toast falls from a 3 foot surface and has different amounts of jelly, then the heavier (18 grams) will fall jelly side down 60% of the time because the jelly will weigh it down. When it is lighter (8, 12, and 14 grams) it will fall jelly side up 65% of the time because it is lighter.
Materials:
4 pieces of Shaws white bread (toasted)
1 garbage bag (cut)
52 grams of Stop and Shop Grape Jelly
4 small Dixie paper cups
Procedure:
1) Measure jelly into 18, 14, 12 and 8 grams in a Dixie cup. Spread the jelly onto four pieces of toast (toasted). Label the bread so you know how much jelly is on each
2) Put down a cut up garbage bag
3) Put toast on a 3 foot surface a push it off the surface. Try to keep you push the same each time.
How the Jelly Toast Fell:
| How much jelly | Jelly Fell Up | Jelly Fell Down |
| 8 grams | 17 | 13 |
| 12 grams | 5 | 25 |
| 14 grams | 3 | 27 |
| 18 grams | 4 | 26 |
Conclusion:
The purpose of this experiment was to see if jellied toast fell jelly side down all of the time. If jellied toast falls from a 3 foot surface and has different amounts of jelly, then the heavier (18 grams) will fall jelly side down 60% of the time because the jelly will weigh it down. When it is lighter (8, 12, and 14 grams) it will fall jelly side up 65% of the time because it is lighter. This hypothesis was false because in the data, the jelly side down fell down more often. Our percentages were off. On all the pieces of toast except for the one with 8 grams of jelly, the toast fell jelly side down more than 5 times more than it fell down. The toast with the 8 grams of jelly fell jelly side up more times than down which supported our hypothesis. Some errors are that we jellied the bread on a different day which made the jelly soak into the bread which might have impacted the final results. Also, one of our pieces of toast had mold on it from sitting out too long. If I were to do this experiment again, I would do the experiment the same day I jellied the toast.
