## Light Science for Kids: Ways to Explore Refraction and Reflection

Â© 2007 Publications International, Ltd. These ideas will be discussed in more detail. The light was shined at a controlled 45degree angle for both tests onto the setup and then were tested with different liquds. If the light bulb is located at a different location, the same principles apply. Students should be able to look at any scenario and ask themselves if the light ray is traveling through one medium or more than one medium. She holds an Associate of Applied Science in child development from Mesa College.

## Refraction

Science Fair Project done By Jason E. The physics behind the basic slide projector basically deals with the different lenses and mirrors inside the body of the projector. In the case of this investigation the medium completely blocked the ray of light from going any further. Leave a comment below to submit your guess. Date: February 28 This past week, we began developing a working model of a projector.

Because the mineral oil has the same refractive index as the glass rod as light moves through the beaker and into the glass rod, there is no refraction and as a result the glass rod will appear to disappear. Three trials were performed for each liquid. Why just read about it and when you could be interacting with it? Which medium allowed light to travel through it in a perfectly straight line? The top of the duck is above the water. Let the kids gradually move the water-filled bottle in front of the sticky note. Does it travel in a straight line as well? Transparent pronounced Trans-pair-ent describes a medium that blocks very little to no light.

## Light Reflection and Refraction off Liquids

Watch the video below about the archer fish and how it uses refraction to its advantage. These machines use a series of mirrors to project images and documents by way of refracted light from a light bulb. Disclaimer and Safety Precautions Education. For our experiment, light rays will be passing through two mediums: air and glass. At the point where the light from the object converges, a replica, likeness or reproduction of the actual object is created. You have the option of setting up the as we did, or doing it right now with the glass of water sitting next to you! Through trial and error experimentation, in addition to the information that we have gathered about lenses thus far, we were able to use three convex lenses in order to project a test slide onto a large projector screen.

## Demonstrating Refraction

In addition, through experimentation we were able to determine that images are always magnified upside-down, which will need to be taken into consideration when constructing our projector. We learned that occurs because light bends when it passes through substances, such as water and plastic. How is a lunch line at school similar to the way a light ray travels? This is equivalent to the ratio of the image distance to the object distance. The task of determining the direction in which an incident light ray would reflect involves determining the normal to the surface at the point of incidence. Students explore the great-billed heron and the archer fish.

## Reflection of Light and Image Formation

The farther the beam is from perpendicular when it hits the surface, the more strongly it is bent. This is because light travels in a straight line through the air unless acted on by another material, which scientists call a medium. After light passes through the focal point, the rays cross over each other and cause images to appear reversed. In addition, the water acts as a magnifying glass, which bends the light toward the center. Do you have a Science Fair Project of your own that you would like to see added to our listings? Unlike plane mirrors, the object distance is not necessarily equal to the image distance. In addition to using both convex and concave lenses on their own, we are potentially considering using a compound lens consisting of both a convex and a concave lens in order to better enable us to project our image. The science behind the water refraction experiment: Refraction is the bending of light.

This demonstration can also be done by replacing the aquarium and water with a small transparent plastic block, which can be bought at a local plastics supply store. Regardless of the observer's location, the observer will see a ray of light passing through the real image location. The index of refraction was measured by using a laser pointer. For example, when light crosses through a window, it is refracted and can create a rainbow. On the other hand, when the object is located between the center of curvature C and the focal point F , the image is located beyond the center of curvature C. If we move the laser pointer to the heavy liquid, because this liquid is more dense than water, the index of refraction is greater and we can see a greater angle in the laser in the liquid.

Finally, the Thins Lens Equation is used again for the second lens to find where the final image will be projected. For fifth-grade students, this is the critical understanding, rather than reflection is bouncing and refraction is bending. Kids and adults will stare in amazement and scratch their heads wondering what caused the arrow to change direction. Oh â€” put the lid on before you do this too! In the last section, you saw that the metal plate blocked the light ray completely. Our are back and this week, we're adding a touch of 'magic'! Once the reflected light rays reach the image location, they begin to diverge.
