4th Grade students have been studying light and sound. In the STEM Lab we explored more about the properties of light. Our focus was on REFRACTION, REFLECTION, AND ABSORBTION. Students took part in activities that helped them to see these properties working.
Students used prisms and cd's to separate white light in to the color spectrum. The Broken Pencil activity showed the students how refraction, or the bending of light can cause a pencil to look broken when placed in a glass of water.
Mirrors are used to help students learn more about reflection. They tried passing light around their tables using the mirrors.
The color of the objects that we see is largely due to the way those objects interact with light and reflect or transmit it to our eyes. When visible light strikes an object and a specific color becomes absorbed, that color of light will never make it to our eyes. Any visible light that strikes the object and becomes reflected or transmitted to our eyes will determine the color or appearance of that object. So the color is not in the object itself, but in the light that strikes the object and ultimately reaches our eye.
The "Hidden Message" activity was a fun way to show kids this property.
Mrs. Guckert is the STEM Lab Teacher at Rocky Mount Elemetary. This is her 4th year teaching at Rocky Mount. The STEM Lab is fully funded by the Rocky Mount Elementary School Foundation. This program would not be possible without the generous donations to the Foundation from the Rocky Mount community.
