It can be tough coming up with science fair project ideas on your own. Sometimes we need a little help. Here is a science project that might work for you.
For this project you will need to know a little bit about skydivers. A skydiver is a person who jumps from an airplane while it is flying. The airplane must be flying a certain number of feet off the ground or altitude for the skydiver to be able to jump and land safely with a parachute.
The skydiver jumps from the airplane and will free-fall for a little bit before pulling the rip cord to open the parachute. The parachute will then slow down the skydiver's fall so he or she will land safely on the ground. If the skydiver falls too fast, his landing wouldn't be nearly as gentle and the skydiver would probably get hurt. Remember, as science fair ideas go, this is a topic and experiment overview.
How does the parachute work?
When the skydiver jumps from the airplane, the force of gravity it pulling him or her to the ground at a very high speed, the parachute is able to slow the skydiver's fall because of air resistance or drag. Air gets underneath the parachute and pushes it back up. This creates a force, which is opposite of the force of gravity, which is pulling the skydiver down.
While the skydiver falls slowly, these two forces of pushing air up and gravity pulling him down are close to being equal or in balance. The air resistance force is just a little less than the gravity force and because of this the skydiver floats down to the ground.
So ask yourself this question, is the size of the parachute important? Could it be smaller or larger and still work the same way? What does the diameter of the parachute have to do with the size of the parachute?
Research Topics
If science fair project ideas like this one appeals to you, I may know a little about the words you will be using a lot of if you do this project, but you will still want to research them. You will need to know more in order to do the project well. Here is a list of the subjects you will want to do some research on, so that you will have a better understanding of what they are and what they mean.
- Parachute
- Air resistance
- Drag
- Load
- Gravity
- Surface area
All experiments and science fair projects have a question to answer. The answer to the question is the reason we do experiments. We want to know the answer. Here are some questions you might have with this project.
- How does a parachute work?
- Does the size of the parachute make it work better?
- Will the parachute work, if it were larger or smaller?
- Will increasing the diameter of the parachute make it bigger?
This is a list of some of the items you will need to complete your project.

A great resource for science project ideas, as well as how to do them, is the science project blog. Definitely worth bookmarking.
Good luck!
Such kind of science fair project is more effective for increasing the students knowledge and i think students also like this education in here. For more inspiration such kind of projects need so more.
