A manipulated variable is the thing that can be changed in an experiment. example; your trying to see what paper towel would be more absorbant, your manipulated viariable would be either the type of paper towel you use or the liquid you use to test the absorbancy.
This question is debatable. Lined paper is lighter, but that doesn't mean it flies better. I think that it's all about how you fold it and which design you choose. If one WA yto do an experiment, I would predict that lined paper would fly a little father, but not by much.

they both fly and/or glide
almost nothing, its to light
An experimental constant is a parameter of an experiment that doesn't change throughout the course of the experiment. Launch height could be a constant in a glide ratio experiment featuring several paper airplanes.
The independent variable is the thing in the expeirment that you purposly change. If I took different sizes of paper airplanes and counducted an expieremnt to see which one went the farthest, the size of the airplanes would be the INDEPENDENT VARIABLE while the distance of flight would be the RESPNDING VARIABLE P.S- there can only be one independent variable in a controlled expierement.
Independent and dependent variables are graphed on the axes of a rectangular grid (e.g. graph paper). The important thing is to understand which is which. The independent variable is graphed on the horizontal (x-) axis. In an experiment you choose values of the independent variable and measure the values of the dependent variable (it "depends' on the other). The dependent variable is graphed on the vertical (y-) axis.

what can be the constant in the paper plane experiment
With your head, pen and paper or on your computer
Depending on how the experiment is set up, the control could be different. In this case, the control would most likely be the regular toilet paper since nothing new is added to it. The control in an experiment is the group that does not contain or relate to the independent variable (the thing you change). So if you are testing to see which is better - regular toilet paper or enriched toilet paper - the control would be the regular paper since nothing is special about it.
A good experiment needs to be a fair test so to have a fair test you need to have a independent variable, a dependent variable and a controlled variable. Independent Variable: The thing you change Dependent Variable: The thing you measure Controlled Variables (there's usually more than one): The things you keep the same. For example if I have 3 kids and I want to find out who can open presents the quickest the independent variable: would be what kid is opening the presents the dependent variable: would be how quick the kids were so their time and the controlled variables: would be the size of the present they used and the wrapping paper on it. Also a experiment should be repeated twice for the best results and then averaged. A bad experiment wouldn't be a test for example changing what should be a controlled variable so if one kid had to open a bigger present than the other kid they would take longer than they would with the same size present so you wouldn't get good results.

Independent: The heat Dependent: The result
In general yes. But it really depends on the experiment. If you want to know if it hurts to punch a wall, you don't need an independent variable (unless you want to compare the magnitudes of the pain). But for school experiments, most of the time, if not all of the time. Yes.
