Lice are only about the size of sesame seeds. They can be divided into two groups, sucking lice and chewing or biting lice. Learn more about these pests in this title.

We can't see bacteria, but it is everywhere - in the air, in the ground, on our hands, even in our bodies. These microscopic single-celled organisms have inhabited earth far longer than humankind and live in almost all the habitats the planet provides. The study of bacteria provides fascinating insight into early history and has an endless depth of knowledge to be discovered.

Viruses are behind many types of illness, from mild colds to severe diseases like acquired immunodeficiency syndrome (AIDS) caused by the human immunodeficiency virus (HIV). Even COVID-19 itself is mild for some and severe for others. Viruses have been found all over the Earth. Researchers estimate that they are ten times more common than bacteria. These tiny germs, that are not even a cell themselves, invade other organisms and are an unavoidable part of our lives.

Kids love activities of all kinds, and projects about plants are the perfect way to engage them in learning crucial curricular concepts such as adaptations, plant parts, photosynthesis, and germination. This beautifully designed volume introduces plant topics, clearly explaining the information learners need to know and the facts that will make them say, "Wow!" Then, step-by-step instructions encourage them to review concepts while completing a related craft or activity, such as creating a leaf stencil, making a plant growth chart, dissecting the parts of a flower, and much more. A final quiz allows reader to assess their understanding of plant facts.

It is easy to be grossed out by fungi or worry about its impact on our health. While both are valid concerns, fungi and mold are actually important to our everyday lives. Like bacteria, fungi exist almost everywhere on the planet. They are hardy organisms the thrive in places you might not expect. Also like bacteria, they are essential in the breakdown of dead and decaying matter. One important group of fungi that does this is known as saprophytes. These fungi use decaying matter for nourishment, and without them breaking down organic matter throughout the environment, life on Earth would be quite different. Without fungi, the world we know could not exist.

Microbes are everywhere! They live on and under the ground. They live in all kinds of water on Earth, even around the hottest deep-sea vents. They even live on and inside your body! Since the advent of powerful microscopes, scientists have been studying our world's smallest denizens. Many people get scared just hearing the words "bacteria," "fungus," and "virus" because of the diseases they cause. However, scientists have discovered many beneficial microbes that actually help support all life on Earth. Geneticists have sequenced the genomes of numerous microbes, extending our knowledge of the organisms and how they affect our lives.

This book discusses insect adaptations and features 20 fascinating science facts.
