In the leveled reader Sponges, fundamental science concepts in biology are explained through simply written text and colorful illustrations and photographs. Young readers discover that sponges are soft-bodied animals that live in oceans and fresh water. Sponges can be very small or very big and come in different colors and shapes. Some sponges are used by fish as hiding places. Although some sponges look like plants, sponges are not plants but...

Zappity ZAP ZAP! A Look at Electricity is a simply written, colorful science book that introduces young readers to electricity-a basic concept in physics. Students learn that electricity can cause hair to be attracted to a balloon, give a shock, run toys, and make toast. Electricity is a general term for electrical energy, and it comes from the electrons in atoms. Energy is needed to do work, which happens when a force moves an object. Force i...

What Is Exercise Science? is a simply written, colorful book that introduces young readers to the study of exercise. Students discover that exercise scientists study how the body works to perform different tasks such as jumping, running, climbing, and lifting heavy things. Exercise science explores how the body works, how exercise changes the body, and how the body uses food. Exercise scientists want to find out the best way to ride a bike, th...

In Wheels on a Bike: A Look at Rotational Motion, fundamental scientific concepts in physics are explained through simply written text and colorful, fun illustrations. Young readers learn that any object that is moving in a straight line has linear motion. A bicycle moving in a straight line has linear motion, but because bicycle wheels are round and move in a circle, the wheels also use nonlinear, or rotational, motion. The word rotate means ...

In the leveled reader Baseballs, Hockey Pucks, and Busy Ants: A Look at Linear Motion, fundamental scientific concepts in physics are explained through simply written text and colorful, fun illustrations. Young readers discover that any object moving in a straight line has linear motion. When moving in a straight line, objects such as hockey pucks, baseballs, and bicycles have linear motion. Living things such as ants, snails, horses, and peop...

Exploring the Building Blocks of Science Book K Activity Book is a fun way to introduce the youngest learners to the five core science subjects: chemistry, biology, physics, geology, and astronomy. There are activities for coloring and drawing, doing outdoor activities, making observations, answering questions, and more. Concepts such as atoms and molecules, characteristics of living things, laws of motion, what Earth is made of, and the moon ...

In the Sea Jellies leveled reader, fundamental science concepts in biology are explained through simply written text and colorful, fun illustrations. Young readers discover that sea jellies are soft-bodied animals that live in oceans, and although they used to be called jellyfish, they are not true fish. They have different shapes and sizes and swim by moving water in and out of the bell, the name for their body. Some sea jellies have tentacle...

In the Inertia leveled reader, fundamental scientific concepts in physics are explained through simply written text and colorful, fun illustrations. Young readers learn that physics explains that force is any action that changes the location of an object, the shape of an object, or how fast or how slowly an object is moving. The Greek philosopher Aristotle thought force is what makes things move. However, the Italian scientist Galileo found th...

In the leveled reader Photosynthesis, fundamental science concepts in biology are explained through simply written text and colorful, fun illustrations. Young readers discover that photosynthesis is the process by which plants use sunlight to make their own food. The green parts of a plant are green because they contain a large, special molecule called chlorophyll. The job of chlorophyll is to catch sunlight and send it the chloroplast, the or...

In the leveled reader Animals, fundamental science concepts in biology are explained through simply written text and colorful, fun illustrations. Young readers discover that there are many different kinds of animals that look different from each other. Animals have different characteristics such as fur, scales, or wings, and have different numbers of legs. Animals live almost everywhere: in the ground, in water, and in trees. Some animals live...

In the leveled reader Plants, young readers will discover that plants grow almost everywhere, in many different environments. Plants have different parts, including stems, leaves, roots, and flowers. Roots keep plants from getting blown away and gather water and minerals for the plant to use in making food. Stems move water and minerals from roots to other parts of the plant and move food made in the leaves down to the roots. Leaves catch sunl...

In the leveled reader Plant Cells vs Animal Cells, fundamental science concepts in biology are explained through simply written text and colorful, fun illustrations. Young readers will discover that plants and animals have different types of cells. Cells are made of atoms and molecules and do different jobs inside living things.Both plant cells and animal cells are surrounded by a cell membrane and have organelles, which are structures inside ...

Energy Is a simply written, colorful reader that introduces young readers to a basic concept in physics. Energy is what is needed to do work. Work happens when force moves an object. Force is any action that changes the location, shape, or speed of an object. Food gives the body the energy it needs to do work. Energy comes in many forms, including food, batteries, and gasoline. A pronunciation guide for scientific terms is included. 24 full co...

Microscopes is a simply written, colorful introduction to an important and commonly used scientific instrument. Young readers will learn that some objects are too small to be seen with the eyes alone, for example, red blood cells and atoms, but a microscope can be used to magnify them to a size that can be seen. A light microscope has lenses for magnifying the sample, a stage to hold the sample, and a light to illuminate it. Red blood cells ca...

In the DNA leveled reader, fundamental science concepts in chemistry are explained through simply written text and colorful, fun illustrations. Children will learn that DNA stands for deoxyribonucleic acid, which is a polymer made of two long strands wrapped around each other in a double helix shape.
