Our parachute experiments independent variable is size, we made a small one, medium one, and a large one to see how they do in our experiment. The dependent variable is the time it takes to go to the ground. The two constants are the amount of holes and the length of the string. We will be cutting out a different size circle for every parachute, and the string size for each parachute will be the same (15 inch.) which is the constant. This also has a hole on the top, because we did experiments to see how the best parachute will work, and the best works with a small hole on the top.
- We are trying to discover how well these parachute designs are going to work
- If the size affects the time of the parachute descent, then the big one will do the best because it has the largest canopy. It will produce the most drag which will slow down the parachute and therefore it will go to the ground the slowest.
- Variables:
-Independant; Size of diameter(Small 20 inches, medium 25 inch, Large
30 inch.)
-Dependant; Time that it takes to drop
-Constant; length of String
- Materials:
-Garbage bag
-String
-Rubber band
-Egg
- 1. Put a rubber band on the egg
- Cut 4 pieces of string (15 inches each)
3.Tye the string onto the rubber band
- Tye the string onto the holes in the garbage bag (one in each quadrant)
5.Repeat for each size parachute.
- Go to the stairs near the nest (8 meters high)
- Mr. Turner will drop each parachute from rest three times.
- Record the time it takes for each parachute to reach the ground.
- Record data in data table.
- Analyze data .
This is one of our parachutes. As you can tell from the picture this is our small parachute. This parachutes independent variable is size, we are going to cut out a 20 inch circle from a plastic bag for the canopy.
This is our medium size parachute. The canopy is 25 inches and I think it will do the best.
This is our large parachute. This parachutes size will be 30 inch. This parachute is practically the same thing as all the other parachutes. It still has a hole at the top, and it’s still the same size string and egg.
