For a project, I need to create an experiment where I remove a heavy metal from water, in my case, iron. I've been doing a lot of searching online so far, and most of what I have found does not relate. I need something that I can actually perform myself, preferably something that I can make on my own.

I heard something about using chlorine to make the iron turn to a less soluble form, and then filtering it but I dont know how exactly to do that.

I just don't know where to start on that idea though. Would I need to acquire some type of Iron, and then get some chlorine? Just let them react in water and filter it? What would I use as a filter? We have filter paper in our classroom but I don't think that'd do it.

Take a look at the Fe(OH)₃ solubility.

Take a look at the Fe(OH)₃ solubility.

Took me a while, but the source I looked at said that Fe(OH)₃ is insoluble in water. (It said all hydroxides were insoluble in water.)

Does that mean that if I change the iron in the water into Fe(OH)₃, it will be the precipitate and can then be filtered out?

From my research, I believe that dissolved ferrous iron is what is present in the water. So would something like chlorination change the ferrous iron into Fe(OH)₃?

Yes, although you must check if there are no complexing agents present that can keep Fe³⁺ dissolved.

chlorine oxidizes the iron(II) to iron(III)

Its simple actually.
Just heat the mixture.

This will liberate the H20 as a gas : H20(g)
this water can be collected by letting the vapour condense on a cold surface

Question was to remove iron from water, not water from iron.

While distillation will work, it requires a lot of energy, there are simpler and much cheaper ways of getting rid of Fe from the solution.
