Weather changes daily. Sometimes it can even change from one moment to another—like a sudden storm. Weather affects our daily lives from what we wear to what outdoor activities (or lack thereof) we can do. Learning about weather and how to dress and prepare for it is an important skill to learn. Maybe even more important is the skill of observation. By asking simple questions, children become engaged and can start to observe and make correlations about the weather around them so they will understand how the weather impacts their lives.
What would it be like to live as a dinosaur? Young readers will discover that dinosaur lives had many similarities to present-day animals: they hatched, ran, hunted, hid from predators, and grew to adulthood.

Repetitive sight words make this a great story for beginning readers and dinosaur enthusiasts alike.

Chemical World: Science in Our Daily Lives explores some of the materials—all of which are made of basic chemical elements—that humans use or come into contact with in their day-to-day lives. Some of these chemicals are naturally occurring—clay, mercury, lead. Others have been synthesized by chemists during the past 150 years and used in a bewildering array of products ranging from roof shingles to toothpaste. Many chemical inventions, as well as naturally produced chemicals, have had profound effects on food supply, developing medicines and creating hosts of useful items for modern life. Despite people using both natural and synthetic chemicals with (mainly) good intentions, some chemicals have had unintended negative consequences. Chemical residues have contaminated ecosystems the world over and are compromising the health of many ecosystems, animals and humans. The goal of Chemical World: Science in our Daily Lives is to introduce readers to basic chemistry and chemical history, and to show how chemicals are used for particular reasons but sometimes turn out to be harmful to environmental and human health. It invites readers to take a look at the world around them and ask questions about what’s in their environment and how the things they use and eat every day can affect their own health and the planet’s health.
