Wait for a sunny day, and pick a spot which isn't very windy.
Pick a sheet of newspaper with as much ink on it as possible.
Scrunch it into a ball with a nice area of black exposed on the outside, and put it in the tray.
Move the lens over the newspaper and move it up and down and twist it until you have the smallest spot possible focused on to a black bit of the newspaper.
Keep the spot focused on the surface of the paper, if a hole starts to form keep the spot inside the hole.
Obviously, this will get very hot so don't touch it, and you are setting fire to something so don't put your fingers near the focus point and don't do it inside!

If you are trying to do it for first time then take a black coloured sheet.
Then keep a convex lens (magnified glass) between the sheet and sunlight.
Then move your lens unless a small point of sunlight appears on it.
Wait for some time and then see the paper burns.
