IN A DIFFERENT LIGHT is a cohesive unit of six lessons for grades 6-12 that
develops the understanding that visible light is composed of a full range (spectrum)
of colors of light from red to violet, that extends the concept of a spectrum to
include non-visible light (infrared and ultraviolet) through discovery, and that
develops tools and strategies for student inquiry.

Lesson 1 - Mix It Up
Mix It Up, is designed to help your students to
understand that the color we see is a particular color of light reflected
from an object. This activity will also introduce the concept that white light
is a combination of other colors.

Lesson 2 - Prisms and Rainbows
Our eyes and brain interpret the simple mixing of only 3 colors of
light (red, green, and blue) as white. The students were able to confirm this
in the last lesson. In this lesson students will develop the understanding
that "white" light from the Sun and "white" light from an artificial light
source is a full range of colors from red to violet. Students will also learn
how droplets of water function as prisms to separate this full range of
colors into rainbows.

Lesson 3 - Exploring Spectra
Students will understand that elements emit light in a distinct
spectrum that can be used to identify the elements and that this information
can be used to identify the composition of complex light sources like stars.
Students will expand on their understanding of the visible light spectrum.

Lesson 4 - Getting Hotter?
Students will discover the existence of non-visible light, infrared,
outside of the visible light spectrum. Students will learn how infrared is
used in science. Students will also develop experimental techniques useful
for further exploration of the light spectrum.

Lesson 5 - Mystery Light
Students will develop research techniques useful for further
exploration, using models developed in previous lessons. Students will design
their own experiment to explore the conditions under which special beads
change color. Since these beads actually change in the presence of UV light,
this lesson will allow them to discover the existence of another non-visible
light, ultraviolet, outside of the visible light spectrum. Students will also
learn how ultraviolet light is used in science.

Lesson 6 - Independent Investigation
Students will choose an inquiry into the nature of light, design a
procedure to investigate their question, revise the procedure based upon
peer review, collect data, and report their results and conclusions.
