Glow: Animals With Their Own Night-Lights
Written by W.H. Beck
Why be afraid of the dark when there is so much to see? Whether it’s used to hunt, hide, find a friend, or escape an enemy, bioluminescence–the ability to glow–is a unique adaptation in nature. In this fun and fascinating nonfiction picture book, join world-renowned photographers and biologists on their close encounters with the curious creatures that make their own light. Author’s note and bibliography included.
Primary Source Pairing:
Glow is a fascinating look at animals who create their own light using bioluminescence. The majority of creatures who have this adaptation live deep in the depths of the ocean. For this primary source pairing, connect math and text features by using the Ocean Depth chart to track where these creatures live in the water. The last two pages of the text in Glow: Animals With Their Own Night-Lights show where in the ocean these creatures live and where the bioluminescence occurs. Make a copy of these two pages and print out the Ocean Depths chart. Invite students to find which creature lives the deepest, which creatures live in the same depth, and how the depths of the creatures compare to the milestones listed on the Ocean Depth chart.
Questions for Discussion:
- What place or places does the map / chart show?
- What on the chart looks strange or unfamiliar?
- What do you find interesting on the chart?
- Find two creatures who live in the same depth. What is similar about these creatures? What is different?
- Find an interesting fact on the Ocean Depth chart. Find a creature who lives closest to that same depth.
