An independent variable is something that u change in the experiment. I will be making 5 different types of paper airplanes and see how far they fly. As I change the independent variable it will influence of how far or short the flight is. My expected outcome of my experiment is the hammer because it has a heavy tip. On scenicebuddies.org it states that if the tip is heavier it fly’s farther. Yes there where another’s that have replicated this experiment, their outcomes where that the ones with a heavy tip fly farther, yes this supports my hypothesis. I will repeat my trials 3 times each airplane. My experiment applies to the real world by, if u r in class and you want to send a note to someone across the room you need to know which airplane
