Awesome Snake Science! ›

Trade Paper

Published Jul 2012

From cobras and copperheads to pythons and boas, all types of snakes are covered in this book of 40 science experiments, art projects, and games that helps budding herpetologists gain a greater appreciation for these slithering reptiles. Activities include making foldable fangs to learn how snakes' teeth and jaws work together; simulating cytotoxic snake venom while making a tasty snack using an everyday enzyme found in pineapple; and mimicking the sound a rattlesnake makes by using a rubber band, a paper clip, and an envelope. Engaging, simple, and safe experiments teach kids about the biology of snakes, such as how they use their tongues and nostrils to detect smells, how they are cold-blooded and sensitive to subtle changes in temperature, and how they can detect the slightest vibrations or tremors. Kids do not need a snake for any of the activities and will delight in all the strange snake facts and gross-out projects such as Snake Stink—where they create their own signature stink and test how well it repels potential predators.

AAAS Subaru SB&F Excellence in Science Finalist 2016
NSTA-CBC Outstanding Science Trade Books for Students K-12 2016

An engaging book that encourages young nature enthusiasts to explore the world of birds

This generously illustrated, full-color book teaches kids that birds can be seen almost anywhere: in city parks and streets, zoos, farms, and backyards. Using “Try This,” “Look For,” and “Listen For” prompts, Birdology promotes independent observation and analysis, writing and drawing skills, and nature literacy. Kids observe the diversity of shapes, colors, patterns, and behavior of birds; listen for their songs and the clap of wings; make a juice-box feeder; plant flowers that attract hummingbirds; start a birding journal and sketchbook; and much more. Other topics that are presented in clear, kid-friendly prose include migration, nesting, food, territories, and conservation and preservation. Additional resources, such as a glossary, bird orders and scientific names, bird and wildlife organizations, and “Teacher Topics” to initiate classroom discussion and investigation, are also included.

Plantology ›

By Michael Elsohn Ross

Trade Paper

Published Feb 2019

Plantology guides young nature enthusiasts on a journey into the world of plants and the role they play in our lives. Full of colorful photos and illustrations, this fun and interactive resource presents clear, kid-friendly discussions of plant topics from the underground up—from seeds, roots, and sprouts to plant skeletons, leaves, petals, flowers, and fruits. But naturalist Michael Elsohn Ross goes beyond plant basics to explore the unknown world of common weeds, fascinating plant defense systems, the marvelous mechanisms of seed dispersal and pollination, and the history of everyday plant products in our homes. Plantology also illuminates humans’ connections with plants and the solutions they offer, from low-cost sewage treatment and toxic waste removal to providing new medical cures. With encouragement to “Try This” and “Look For,” kids participate in 30 hands-on activities that promote observation and analysis, writing and drawing, math and science, and nature literacy skills. They will keep a plant journal, examine and sketch plant shapes, colors, and structures; start a seed collection, make tasty plant dishes, and more. Readers from any region will start to take notice of the plants around them—not just in parks, gardens, and woods but also around the schools, buildings, and sidewalks of their town, and in their own backyards. Useful resources include a glossary of plant terms, a list of plant and nature organizations and groups, and a teacher’s guide to initiate classroom discussion and investigation.

They form partnerships with plants and help us clean up our planet through bioremediation. Some fungi eat our crops; others protect them. Some fungi cause diseases; others cure them. Some are bigger than you; others are so tiny you need a microscope to see them.

And now, people are finding ways to use fungi to make furniture, building materials, and even sneakers.

So grab your gear and let’s go find some Funky Fungi.
