Refraction is the bending of light. In this example to the left, the light travels through air, glass, water, back through glass, back through air, and to the arrows. The light rays refract to a center point, or focal point, in the water. As the light goes beyond the focal point the image behind it appears reversed. ]]> 2021-04-25 03:32:36 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455495387 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455507836 2021-04-25 03:51:41 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455507836 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455508495 2021-04-25 03:52:41 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455508495 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455509226 2021-04-25 03:53:47 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455509226 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455510119 2021-04-25 03:55:06 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455510119 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455513896 2021-04-25 04:01:04 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455513896 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455514224 Grade Level: 4th grade

Also we have lots of water in Louisiana (rivers, ponds, lakes, swamps, bayous)that cause light refraction with cause not only this phenomena but also rainbows. The conversation of light refraction can then lead into prisms and rainbows. ]]> 2021-04-25 04:10:41 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455520251 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455521838 NGSS defined natural phenomena as: Natural phenomena are observable events that occur in the universe and that we can use our science. knowledge to explain or predict. This is a phenomena because it meets those requirements. The reversal of the arrow is something that we can observe, and it can be explained through the scientific principles of light refractions. ]]> 2021-04-25 04:13:00 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1455521838 rebethom17 https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1461949483 Index refraction of water is different of that of air. Refraction is the bending of light. Light going through water is at a different velocity than that going through air. That difference is reflected in the index of refraction. Because the light slows down, it goes in hits the arrow and then comes back out. Index of refraction measures how fast light goes through the material.
If you have a pencil on it's own, you see it normally as a straight line. the time it takes for a light to bounce of the pencil is linear. When the light goes into a slower medium (water), then the light takes longer to go in the water and back to the eyes. ]]> 2021-04-26 23:20:59 UTC https://padlet.com/rebethom17/2ofr6t6f1zkxnqlv/wish/1461949483
