∙ 12y agoIt all depends on how well you focus the beam of the magnifying glass. You need to adjust the distance from the glass to the paper until the light from the sun is concentrated in a tiny brilliant white spot. That spot is very hot as well as bright and so the paper is heated enough to start charring. It may even catch fire, so be careful to try this on a safe surface like concrete or stone paving.
Try not to look at the bright spot with unshielded eyes, as it is bright enough to damage your eyes.

∙ 12y agoIt's quite easy- take a magnifying glass and a dry piece of a paper ( preferably newspaper ) and go to a place where appropriate sunlight is available. Let the light of sun fall on to the magnifying glass. Bring the piece of paper beneath the magnifying glass. Now your objective is to move the magnifying glass up and down in such a way that the light emerging from the magnifying glass concentrates to a point. Hold the both things in the same position for a while, and soon you will be able to see the miracle, fire without a matchstick ! Enjoy!

It actually depends on what you're trying to burn a hole through. It can from a thin piece of paper to a large block of wood. I have only tried it for paper, and this is what I did: You make a spot on the piece of paper where you want it to burn. Try using a black sharpie because it attracts more heat. Take a typical magnifying lens and hold it between the sun and paper. There should be a weird shape, or dash of sunlight on your mark of sunlight. Make sure the light is refracted right, and is not spread out, but more focused to one point. It all depends on the weather or season really. During the summer, you can go outside and try it, and it will happen pretty fast. For the winter (which I tried), I was inside, in front of a mirror. I had to wait patiently for a few minutes, and the sun was moving by the hour, so I had to make sure my angle was correct. Hope this helps :D
up and down.
Glass definitley does. if you are raising a catipillar or a worm, put in in a BIG Plastic container. It will live much longer. I am a 5th grade science teacher Glass. Put lots of grass cap of water, and make sure it has a BIG BIG BIG plastice container. -Susan DO NOT PUT A CATIPILLAR IN GLASS. It could die quikly from the heat.
My cousin and I used a magnifying glass to see the paper.
dried leaves or paper
The lens of the magnifying glass concentrates the sun's light to a point. At that point the paper is heated to its ignition temperature and it can catch fire

A magnifying glass forms a circular dot where it focuses rays of light from the sun. The focus of a magnifying glass is at a distance from the surface of the glass itself. So a magnifying glass must be held [approximately] perpendicular to the line joining the sun and the target, and at a distance from the target which equals the focal length of the lens.
It depends on the color, so i can't answer that.
the paper will become wet and will tear.
it flies up to the glass
Take a magnifying glass, and you can direct the sunlight to rip through a sheet of paper. Message board me if this isn't enough.

A sunshine recorder! A paper chart is marked with the hours. The magnifying glass is usually spherical so it and the chart don't move. When the sun shines it burns a line on the chart. The most common kind is called a Campbell-Stokes recorder. See a picture at the link below.
The sun emits a particle known as a photon, which carries visible light to earth. These photons contain energy, which they radiate in the form of heat. When you put a magnifying glass in the paths of these photons, the convex lense of glass narrows and focuses the photons, making them converge on a narrower point then if the lense wasn't there. This concentration of photons concentrates the heat that they emit, heating the paper up until it ignites at a certain temperature (about 451 degrees F).
