They did an amazing job. Here are two examples of what they came up with for a page in A Place for Turtles:
Text: Because plastic shopping bags look like jellyfish, sea turtles sometimes eat them by mistake. The plastic can clog the turtle's stomach, causing it to starve to death.
This student thought the art should show the sea turtle in the process of eating the plastic bag (from BJs).
This student decided to show the turtle's stomach clogged with a shopping bag (from TJ Maxx).
Aren't these terrific? Those students were really thinking.
