Transcript of Chuting: A Parachute Experiment

A Parachute Experiment Chuting Parachuting. We have been doing so since World War 1. But how did the people that invented parachutes know they were going to succeed? How did they figure out what shape to make them? Today, we are going to conduct an experiment to see what shape of parachute will fall the slowest and keep the weight (or the person) from smashing into the ground. Will it be shape A, B, or C? Hypothesis: Which shape of parachute will capture more air
underneath the parachute, fall the slowest, and create
the most drag? Will it be A, B, or C? Materials: (What you need) WARNING: Use safety scissors. Also, be careful
when you get to a high place.
(Standing on a chair can be dangerous) Instructions: 1. First, cut out 3 large squares from the plastic bag.
2. Next, trim them so one looks like an octagon
(a 8 sided shape) a triangle, and a square.
3. Now, label the parachutes A, B, and C with a Sharpie.
4. Next, punch a hole with the hole puncher near the edge
of each corner.
5. Attach pieces of string (that are about 30cm
long) to each hole you punched. What's Happening? When you time your parachutes 1 by 1, the
octagon parachute will most likely the last one
to touch the ground, and also have the most time.
A lot of time is good because we are looking
for a parachute that creates the most drag. 6. A small object to be the weight, nothing heavier than 10g.
(a small action figure will work nicely) 3. String 5. A sharpie or marker 4. A Hole Puncher 2. Scissors 1. A plastic bag (garbage bags works best) USE ADULT
SUPERVISION! 6. Then, attach the other ends of the string to the object you are using for the weight.
7. Finally, stand on a chair (be careful) to drop your parachutes. Get a friend to record the time with a stopwatch and right it down on a piece of paper. HINT! If you punch a small hole in the middle of the parachute, it will make the parachute fall straighter. Conclusion: Now you have conducted your experiment. Parachutes are
designed to have a lot of drag. Parachutes fall slowly because air is trapped beneath them. Which parachute shape fell slower than the others and had more drag? It was B, the octagon! BY: LAUREN POWER! Thank you for watching and
