Mrs.
Proudlock's and Mrs. Woolford's seventh-grade science classes at West Middle
School have been studying light.
To
further explore how light behaves the students participated in a six-station
light lab. From the various stations the students gained first-hand knowledge
that red, green and blue light converge to create white light. Concave lenses
make light diverge while convex lenses cause light rays to converge or come
together.
In
another station the students organized a variety of materials under the
headings of translucent, transparent or opaque. Using a diffraction grating the
students were able to see how green, yellow and white light refracts. Finally
in an interesting activity involving a "disappearing" penny, students
understand how light was refracted to make the penny "reappear.”
The
students had a favorable reaction to this assignment. Students positively interacted
with one another. This hands-on assignment made the principles of light come
alive for the students. In real time the students now have a better
understanding of how light behaves.
