__QUESTION__**: Will changing the overlap change how far the glider flies?**

__**﻿hypothesis:**__
if its heavyer its gunna go further

__** MATERIALS **__

we used tape, a straw and paper.our hypothesis is that it is going to go fast and far.…….

__**PROTOTYPE DETAILS**__ our glyder has a 24.5 cm straw and the loops are 20 cm apart. The front ring is 2 cm wide and it is over lapping by 7 CM its 9 cm long cut a strip 16 cm long and 2 cm wide...... **﻿the back back loop is 3 cm..and its 14 cm long it over laps by 1 cm** The back loop is half a cm past the straw. The front loop is half a cm past the straw. We are going to overlap the back loop.

__** VARIABLES **__ Deepend variable-in an experiment the factor that changes in response to a change in the independent variable. independent variable - in an experiment a factor that is selected or adjusted to see what effect the change will have on the independent variable Our independent variable is how heavy our front loop is.

Our dependent variable is how far it will go.

How hard you throw it ,how high you throw it, how low you throw it, the angle you throw it, keep the length of the straw, the length of the loops, the width of the loops, how you thit, if you throw it upside down.

Procedure for flying and measuring gliders:

Analysis:



CLAIM...There is no trend in the data, but the gliders with 9, 11 cm of overlap perform better than smaller or bigger amounts of overlap. Evidence… For the glider with the least overlap (7cm) it went 958 (CM)…the too with the overlap of 9 and 11 went the farthest. The one with the 9 (CM) overlap went 1098 (CM) and the one with the 11 (CM) overlap went 1084 (CM)

__**Conclusio**__n: we got confused when we built our glider and we made a difent change to our front ring than we had planned. so we have no hypothosis to prove or not prove. we keep the front loop the same size of paper but the rings were diffent lengths. as the amount of overlap increased the distence the glider flu it increased and then it decreast. the evidence i have to suppord this claim is that the gliders with the overlap of 9 and 11 went the farthest.. are data isnt completly Reliable because we could not completly controlle how hard we thouew the glider and could of made them exacly the same. to beter confirm our feaults we could do the trail more times than we did. or may be get some one else to throw it. and compare the results.
