Light

May 13, 2016

On Monday, the Otters began exploring light. We learned that light is a form of energy that we can see and is made up of tiny particles called photons. We did a movement activity where became photons ourselves! As photons, we travel in waves but only in straight lines. Some Otters practiced this concept on the SmartBoard! It was exciting to learn that we can see objects because photons bounce off of objects and into our eyes. 

We explored different types of objects to see which ones light can pass through. We discovered that light can pass through transparent and translucent objects, but no light can pass through an opaque object. It was fun to have the lights turned off in the classroom and explore with flashlights! 

Since light cannot pass through an opaque object, a shadow is formed! On Thursday, we went outside and built structures while studying the shadows by tracing them. The Otters had interesting observations and experiences with angles of blocks. One Otter noted that if the block was tilted one way, the shadow looked like a triangle. If the block was turned a different way, then the shadow looked like a parallelogram! This made us wonder about the ways shadows can be changed. We observed that moving the opaque object changes the shadow, but moving the light source will also change the shape of the shadow. On Friday, some Otters traced their shadows during outdoor learning at 10:40 a.m. We returned to the same spot at 1:40 p.m. and our shadows had completely changed! Our light source (the sun) had moved in the sky, which changed the shape of our shadows.
