Reverse Arrow Science Experiment Refraction Of Light Youtube Fill the glass almost to the top. draw arrows on one piece of of card or paper. place the paper behind the glass and watch as the arrow points the other way. now try to think of a word that still makes sense if you put it behind the glass. we tried bud, the green ( badly drawn ) plant is on the opposite side when the paper is not behind the glass. The free stem projects, experiments, lessons and activities below help educators teach k 12 students about the physics of light, specifically, visible light, with hands on exploration and active learning. the resources below have been grouped by grade band to help educators select the experiments and lessons that best fit their needs.
What Is Refraction Light Science Experiments Physics Experiments Refraction is the bending of light. refraction occurs when light travels from one medium to another (ie. air to water, water to air). during the experiment, the light traveled from the image through the air, then through the glass cup into the water, and finally out of the glass cup and into the air once more before it reached our eyes. The rest of the light keeps going through the glass object, but the light is bent (or refracted) as it moves from the air to the glass. the index of refraction for the oil is very close to the index of refraction for glass. therefore, as light travels through the oil and into the glass eyedropper, very little of it is reflected or refracted. Refraction is the bending of light (it also happens with sound, water and other waves) as it passes from one transparent substance into another. this bending by refraction makes it possible for us to have lenses, magnifying glasses, prisms and rainbows. even our eyes depend upon this bending of light. The bending pencil experiment: light refraction. step 1: fill a drinking glass or glass jar with water. we used a mason jar since all of our drinking glasses have an etched design in them. you’ll get the best results with a clear, glass container for this experiment. step 2: hold the tip of the pencil while inserting it into the water.
