Question

 * Do smaller parachutes work better?**

**Introduction**
In the sport of skydiving, a person jumps out of an airplane from a very high altitude, flies through the air, and releases a parachute to help them fall safely to the ground. The parachute slows down the skydiver's fall so that they can land on the ground at a safe speed. How does the parachute do this? As the skydiver is falling, the force of gravity is pulling them towards the earth. The force of gravity can make an object fall very fast! The parachute slows the skydiver down because it causes air resistance, or drag. The air pushes the parachute back up, and creates a force opposite to the force of gravity, slowing the skydiver down. As the skydiver falls slowly to the earth, these "push and pull" forces are nearly in balance. The drag force from the parachute is slightly less than the force of gravity, so the skydiver floats slowly to the ground.

Materials
strings or threads, walmart plastic bag, scissors, Tape**
 * Lego Guy,

Step by step procedure
First grab a lego guy. Then find 2 Walmart bag plastic. Your going to need two strings for this test. Now grab your walmart bag flat out then fold ton the side, then up to the to where the straps are. fold side way twice after the last fold, and then cut it close to the tip of it. Now then put the middle of the string around one tie it then tape it to the parachute and drop it from the second floor. Then do thesame thing again but when cutting it cut more away from the tip.

Experimental group- smaller and bigger size parachutes. Control group- The regular sized miniature parachutes. Independent variables- Changing parachutes Dependent variables- If smaller parachutes works better then a bigger parachute.

**Information-**
Parachutes help in horizontal deceleration. The modern parachute was invented in the late 18th century by Louis Sébastein Lenormand who made the first recorded parachute jump in France. Two years later, Jean Pierre Blanchard demonstrated how to safely disembark from hot air balloon with a parachute. Reserved parachutes usually have a ripcord deployment system first design by Theodore Moscicki, but most modern parachutes had a hand deployed parachute system.

Size** is very important in skydiving.

**Conclusion-**

 * Smaller parachutes can catch air way more faster than bigger parachutes.
