Facts about chlorophyll combine with a sense of wonder.

SUMMER GREEN TO AUTUMN GOLD

UNCOVERING LEAVES' HIDDEN COLORS

Art and text move through summer, fall, winter, and spring to explain the science behind the seasonal changes in deciduous trees.

“What kinds of leaves do you see in the summer?” The opening double-page spread has a stark white background. Seventeen different trees are represented by a scattered array of leaves—each carefully labeled—in many gradations of green. The enticing collage art uses negative space to show the veins. The page turn leads to additional glorious art, affirming the text’s use of such words as “emerald” and “jade.” Lush canopies of summer leaves part just enough to reveal, in the distance, people and a dog paddling a red canoe across a lake. Although all the illustrations concentrate on tree leaves, they occasionally include similar scenes of seasonal human activities—subtle reminders that humans are also affected by nature’s cycles. The text uses some anthropomorphism (trees and/or their leaves conceal “secrets,” “wait,” “make food,” and sleep) as it introduces young readers to chloroplasts, chlorophyll, plant cells, and the process of photosynthesis as well as the role of fallen leaves in an ecosystem. After the final double-page spread, which reveals a world returned to springtime, there are two pages written in a straightforward, scientific manner, supplementing the earlier text with further information about leaves—including differentiation between deciduous trees and evergreens and the names and characteristics of pigments hidden beneath a leaf’s chlorophyll.

A simple but effective look at a keystone species.

IF YOU TAKE AWAY THE OTTER

Sea otters are the key to healthy kelp forests on the Pacific coast of North America.

There have been several recent titles for older readers about the critical role sea otters play in the coastal Pacific ecosystem. This grand, green version presents it to even younger readers and listeners, using a two-level text and vivid illustrations. Biologist Buhrman-Deever opens as if she were telling a fairy tale: “On the Pacific coast of North America, where the ocean meets the shore, there are forests that have no trees.” The treelike forms are kelp, home to numerous creatures. Two spreads show this lush underwater jungle before its king, the sea otter, is introduced. A delicate balance allows this system to flourish, but there was a time that hunting upset this balance. The writer is careful to blame not the Indigenous peoples who had always hunted the area, but “new people.” In smaller print she explains that Russian explorations spurred the development of an international fur trade. Trueman paints the scene, concentrating on an otter family threatened by formidable harpoons from an abstractly rendered person in a small boat, with a sailing ship in the distance. “People do not always understand at first the changes they cause when they take too much.” Sea urchins take over; a page turn reveals a barren landscape. Happily, the story ends well when hunting stops and the otters return…and with them, the kelp forests.

A simple but effective look at a keystone species. (further information, select bibliography, additional resources) (Informational picture book. 4-7)

Despite minor bumps, a ride that’s worth returning to.

HOW TO CODE A ROLLERCOASTER

Pearl and her robot, Pascal, take their coding skills for a spin at the amusement park in this Girls Who Code picture book, a follow-up to How To Code a Sandcastle (2018).

The park has many rides to choose from, and Pearl has 10 tokens to last her the day. But her favorite ride, the Python roller coaster, looks busy. Pearl decides to do something else fun, using code concepts such as variables to keep track of the length of the line and her remaining tokens and a conditional statement to decide when to return to the Python. Throughout, computer science terms are defined crisply in the text and vividly illustrated in the pictures, which use images such as popcorn bags for variables and the Ferris wheel for loops (keeping track of ice cream flavors seems somewhat contrived). The backmatter explains these ideas more fully. Pascal’s too-literal interpretations of Pearl’s statements make for several amusing moments along the way. When Pearl runs short of tokens (a missed opportunity to talk about checking for more than one condition?), she’s undaunted by the disaster, taking readers on a fun hunt for a secret hidden password, in a nod to the importance of proper sequencing. Pearl has brown skin and black curls; others at the park have a variety of skin tones.

Despite minor bumps, a ride that’s worth returning to. (Picture book. 4-8)
