the science questions

7. Describe the effects that the paper clips had on your airplane's flight. Use the following terms in your description: mass, gravity, distance, flight.

-->When it has the paper clips on my airplane, it mass is heavier. Because it has the extra  mass of paper clips. Its gravity pulls down. When it doesn't have a paper clip, it's lighter and more flight distance.

8. Based on this investigation, describe what you think are important factors to consider when designing an airplane.

-->When the airplane has a paper clip on it, it become heavier. And it easier to fall down. It's better if  the air plane  without the paper clip. It's better when it's lighter. When it has more paper clips, it has more mass and less distances. When it has more paper clip at the left wing, it will go left way. But when I put it at the right way, it will go right way. But when I put one at left and one at right, it will go straight.
