The first activity (The Broken Pencil activity) involves a simple and interesting set of Some drawings (or pencil and paper) Instructions for Light bending: For step-by-step instructions on how to conduct this experiment watch the video on the beginning of the article or continue reading… Draw some images you would like to test; Pour water into a glass; Put the image behind the glass and look at it through the water. Water. Experiment further: Now that you have an idea of how refraction works, see if you can think of different ways to make a magnifying lens with water, or make other tricks like the penny experiment. You’ll notice that the pencil doesn’t always appear broken. Place the paper behind the glass and watch as the arrow points the other way. The thicker the bag, the harder it is to get the pencil to pass through. A pencil looks bent in water because of a phenomenon called refraction. That’s why you can still see the penny through the side of the empty glass. Fill the glass almost to the top. refraction ‐ the when?, the why?, and the when not? When going from a faster to … Images that we see are all light rays that reach our eyes. This concept of bending can be calculated by Snell’s Law of determining the “index of refraction, a constant, for light traversing the boundary between two specific media” (light and shadow - let’s do science) The Pencil Experiment. When these light rays travel through air, they experience little or no refraction. As a result, the image of the pencil appears to be broken. Full disclosure: I didn’t know that refraction was what this experiment demonstrated. Instructions. Paper or card. Glass. of refraction. https://www.ency123.com/2016/12/refraction-of-light-experiment-for-kids.html When light enters water, it cannot move as fast as it does in air. Place a pencil in a glass filled with water and what do you notice? What do you see? I found a great light refraction experiment video on YouTube and decided to try it with Tigger. Guiding the activities insures that students get off to a good start on their study of refraction. Depending on where your eyeballs are, you can see an intact or broken pencil. Does sugar water or salt water change how big letters get if you look through it compared to plain water? Bending Light-- sticking a straight pencil into a clear plastic glass of water, the kids are able to see how the light moves through water and appears to "bend" the pencil. Since many of these experiments use water, I would recommend having some of them (especially the rising coin) inside of a big tub. Pens. As light enters water at an angle, it bends away from its original path, and this makes the image look bent. The trick behind the Disappearing Money experiment is the refraction of light. Draw arrows on one piece of of card or paper. Experiment with different sizes and shapes of pencils. As you sight at the portion of the pencil that is submerged in the water, light travels from water to air (or from water to glass to air). When light enters a new substance (like going from air to water) perpendicular to the surface (looking straight on), refraction does not occur. Which type of pencil … Materials for Light Refraction Experiment. Good luck, and keep experimenting. This next activity is a quick science demonstration that can be implemented with or without the student exploration part (but I always love incorporating that because the students love a good challenge that makes them think.) Light Refraction Pencil Science Activity. For a really thin bag, use a plastic bag from the produce section of the grocery store. We’re continuing with our simple science experiments this week by taking a look at light refraction. This light ray changes medium and subsequently undergoes refraction. Some pencils have flat edges while others have perfectly round, smooth edges. Start on their study of refraction medium and subsequently undergoes refraction YouTube and decided to try with.
