New Release Books by Erin Twamley

How many cows live on Earth? There are nearly one and a half BILLION cows on our planet. And those cows have gas! A few gassy cows would not be a problem, but their burps and farts release methane. Too much of this gas causes problems for our planet. So, scientists, engineers, and farmers are working to make cows less gassy. From using lasers to feeding cows curry (What kind of curry do you think a cow likes -- red, green or yellow?), this book shares the science behind caring for our environment.

The climate is changing at a rapid rate. This book explores why. In Climate Change: The Science Behind Melting Glaciers and Warming Oceans with Hands-On Science Activities, readers ages 9 to 12 learn the science behind the changing climate by studying real research from yesterday and today in order to best contribute solutions to the looming problem. Essential questions, cool facts, and links to online primary sources and other relevant material make complex concepts easier to understand.
