Explains how wood is cut and milled; discusses how graphite is produced and pencils are assembled at a factory; and how pencils become available to consumers.
Expanding on our popular Lets Explore Science series, this book focuses on Hypothesis, Theory, and Law. All three of these are important in the process of scientific inquiry, which is the way scientists study the natural world. As they explore, they develop explanations based on what they learn from their work. By forming a hypothesis, testing and evaluating theories, and describing the laws that exist in chemistry and physics, students will learn all about this important science topic. This book will allow students to learn that cause and effect relationships are routinely identified and used to explain change.
Expanding on our popular Lets Explore Science series, this book focuses on the scientific method. The scientific method is a step-by-step process for solving science problems. Scientists use it every day. Explaining each of the five parts: observing and asking questions, researching your topic, forming a hypothesis and testing it, designing and conducting an experiment, and analyzing and drawing conclusions from your result are all mapped out in detail. Learn how this straightforward topic can sometimes be a little trickier than it seems! This book will allow students to generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Expanding on our popular Lets Explore Science series, this book focuses on electricity! We depend on electricity to light our homes, power our computers, and so much more. It all starts with atoms, and this book explains just how these tiny building blocks are at the center of electrical currents. Conductors, insulators, and electrical safety tips are all discussed to make this topic come together. So, turn on the light and read this interesting book on electricity! This book will allow students to make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents.
With an emphasis on how important light is to our Earth, this title explains how light effects photosynthesis, how light travels, the different properties of light and how both animals and people depend on it. Whether it's ultraviolet light that help bees pollinate flowers to solar panels that use the Sun's light to heat our homes, it's all addressed in this beautifully illustrated book.
This title teaches students that everything is made of matter, and that physical changes create different forms or states of matter. Gives examples of these different states in easy to understand text and introduces students to the Law of Conservation of Mass.
STEM technology is a very important topic in today's world and this book will allow students to learn more about atoms, molecules, how different temperatures and situations affect them. It also introduces them to the periodic talbe of elements and how even today more elements are being discovered and the periodic table continues to grow
