A garnet's deep red color can easily be mistaken for a ruby by the untrained eye. However, garnets' color ranges from colorless to black to red and even green! They've been precious gems for many thousands of years, commonly found in metamorphic rocks. This volume introduces readers to the creation, structure, and properties of garnets. Dazzling photographs highlight the valuable gem as important geology topics are explained in an age-appropriate, understandable way. Fun fact boxes offer readers surprising bits of knowledge, such as garnets' use in sandpaper, and a graphic organizer allows readers to process this information in another way.

There are many insects that can--and will--sting when they feel threatened. However, many types can only sting once and their stinger is lost in whatever has been stung. Not the hornet! Hornets have a smooth, supersharp stinger that can be used over and over. That's not the only danger these insects pose--and readers can learn all about it. Full-color photographs allow readers a closer look at an insect better left alone in the wild. Fun fact boxes and a colorful layout augment science content, including the hornet's stinging behavior and the building of their nests.

The good news is that unless you live in Australia, you likely won't encounter funnel-web spiders in your backyard. Vacationing there, though, exposes you to more than 40 kinds of funnel-web spiders, and many are extremely poisonous. This book takes a look at many of these amazing creatures, exploring how they build their funnel-shaped burrows and where they like to live. With full-color photographs of these amazing arachnids in their foliage-filled habitats, readers will discover the wild world of these small but dangerous creatures.
