Title: glider expermient

Question: How will changing the length of the front ring affect how far the glider will fly?

Hypothesis: If i change the front ring smaller i predict that the glider will go further.

Materials:1cm grid paper, tape, straw, 25 cm straw ,scissors

Prototype Details:back ring is 3cm wide and 17cm long, the front ring is 2cm the wide and 12cm long, the straw is 25cm long.the distance betwwen the two rings is 25cm. the straw is taped inside the loop.

Variables:

Independent-in a experiment, a factor that is selected or adjusted to see what effect the change will have on the dependent variable. my independent is changeing the front wing length.

Dependent-in a experiment, the factor that changes in response to a change in the independent variable. dependent variable is the distance the glider flys.

Control- variable that you keep the same to make a fair test 1. where you hold the glider 2.how hard you throw it 3.what angle do you throw it 4. make sure the bottom of the front ring is level to the ground 5.make the glider exactly the same except the front ring

Procedure for flying and measuring gliders i made a start point then i held the glider in the middle then i took one step back then took another step to the starting point then threw the glider gently.im going to measure the glider from the tip of the glider to the start point.

distance glider flew 1. glider 1 6 cm average is 672cm 2. glider 2 8 cm average is 842cm 3. glider 3 12cm average is 742cm 4. glider 4 average is 355cm 5. glider 5 14cm average is 352cm

=
Glider 2 had the shortest front ring and went the furthest, glider 3’s front ring was bigger then glider 2’s and it only went 742cm, and glider 5’s front ring was more bigger then glider 3’s front ring and glider 5 only went 352cm. =====
