Question: If the straw is shorter then will the glider go further?

Hypothesis : if the length of the straw is shorter than the glider will fly further because is would be lighter.

Materials: · Straw · Paper · Scissors · Tape

Prototype details: The back: · Ring is 4m by 14com overlapping 11cm · Straw goes 3cm. then stops

The straw · 24 cm

The front · 8cm by 1 cm overlapping 1cm straw goes in 1cm then stops Small ring is 21.5 from big ring

The distance of the gilder depends on the length of the straw.

 __Independent variable- __ a variable that depends on itself and not anything else
 * our independent variable is the length of the straw .

__Dependent variable- __ when a variable changes in response to the independent variable. <span style="color: black; font-family: 'Arial','sans-serif'; font-size: 16pt; line-height: 115%;">: our dependent variable is the distance of the glider.

 * 3) 3 - 16 cm
 * 4) 4 - 12 cm
 * 5) 5 - 8 cm

Procedure.

1. Place fingers in the middle of the gilder 2. Bring glider back till the middle part is at your ear 3. Throw the glider lightly 4. Arm straightened out 5. Then let go of the gilder.
