Question: How does a glider work?

Hypothesis: I think the glider works because the air goes through the hoops and it glides for a bit

materials; straw paper tape scissors

Glider Prototype

Back loop 16cm long 3cm wide. Front loop 16cm long 2cm wide. Length between loops 19cm long. Front loop has 3cm piece of tape holding the straw. Front loop overlaps 4cm. Back loop overlaps 0.5cm. Tape on back loop 3cm. Tape on back seam 2cm. Tape on front seam 3cm.

Identify variables A) An independent variable is a factor that can be varied or manipulated in an experiment (e.g. time, temperature, concentration, etc). It is usually what will affect the dependent variable.

The length of the back loop.

B) The dependent variable is the variable that is being measured in an experiment. For example, in a study on the effects of tutoring on test scores, the dependent variable would be the participants test scores.

It changes the speed and length that the glider will go

In scientific experimentation, a control variable is the one that must not be changed throughout an experiment because it affects the dependent variables and thus affects the outcome of the experiment. For example, in the experimental verification of Boyles law, the temperature must be kept constant. Essentially, a controlled variable is what is kept the same throughout the experiment. An example of a controlled variable would be if you have experimented on plants and tested a product on two plants, the soil and the pot would be two controlled variables. A control variable is any factor that remains unchanged and strongly influences values;also a factor held constant to test the relative impact of an independent variable. ^^ From Wiki pedia on controlled variables

controlled variables 1. height of the thrower 2.force thrown 3.loop size 4,straw length 5.tape ammount 6.number of loops 7.length of loops 8.position thrown 9.place thrown 10.distance between loops
