** How high can you drop an OREO before it cracks? **
**  Gravity   ** Gravity is what holds you down to Earth. When astronauts are in space, they are floating because they aren’t close enough to a planet to get pulled down by gravity. When astronauts are on the moon or another planet, they get pulled down by its gravity. The Earths gravity holds the moon in its orbit. If we didn’t have gravity, the moon would be floating around in space- and we would be floating around too! This website: http://sciencemonster.com/gravity_inertia.html   is where I got my information. My experiment is “How high can you drop an oreo before it cracks?” and my information helped me understand my experiment more because, if we didn’t have gravity, and you drop something, it wouldn’t drop. It would just float there. But since we do have gravity, when you drop something, it will fall and hit the floor. And chances are, if you drop an oreo, it won’t be long before it cracks. || How high can you drop an oreo before it cracks? || I believe the oreo will make it one foot before cracking.

|| Materials: Materials: 16 oreos A foot ruler A hard surface A recording sheet & a pencil || First, measure 6 inches up from the ground. Place the oreo at the 6 inch mark and drop it. Record whether it cracked or not. Next, measure 8 inches up from the ground. Please, use a different oreo!!!!!! Drop the oreo from the 8 inch mark. Keep moving up two inches and dropping the oreo until you reach 12 inches. Repeat experiment 3 times. **NOTE: A crack** **is when the oreo splits across the top.** ||

Here are my observations: One oreo had a slight crack in it, but it wasn’t counted as a crack. A few of the oreos got dents in them, but they weren’t cracks. These are the things I had to go back and change to make the experiment make sense: I had to change 12 oreos to 16 oreos because I said, “Repeat experiment 3 times” but then everyone was saying they thought to the people doing the experiment it would sound like they would have to the experiment 4 times. So I had to change 12 oreos total to 16 oreos total. Here is what I learned during the experiment: Gravity is mainly what you need for this experiment because if we didn’t have gravity, when you drop an oreo it would just float there instead of falling. And that oreos can’t make it very far before cracking. Oreos crack depending on the speed and distance. When you drop an oreo at 5 inches vs. 10 inches, the oreo you dropped from the ten inch mark will go faster on the way down to the ground. The oreo you dropped from the 5 inch mark won’t go as fast. This is just an example! Please when you are doing this experiment, start at six inches and count by twos until you get to twelve inches. Do NOT drop the oreo from five inches or any other odd number. ||
 * || Conclusions ||  My hypothesis was wrong. It was wrong because my hypothesis stated, “The oreo will probably make it one foot before cracking.” When some of the oreos cracked, it was less than one foot. These are my results: 11 oreos did not crack. 5 oreos did crack. The results are probably like this because 6 inches is not very high up. All four tries at the 6 inch mark did not crack. But at the 12 inch mark, three oreos did crack. Yes, one oreo at the 12 inch mark did not crack. Anyway, the majority of the oreos that cracked were at the 12 inch mark.
