You can't make something out of nothing. This is because there are certain laws that everything in the universe follows. It may seem like magic, but it's really a matter of matter. Join physicists from past and present to uncover the magic of how matter changes yet remains the same in this physical science book. Fifth grade readers will learn about physical and chemical changes; how mass, energy, and volume are related; discoveries that led to the law of conservation of mass, scientific words such as hypothesis, theory, and law; and more through this high-interest informational text filled with vibrant photographs. Aligned to the Next Generation Science Standards, a hands-on "Think Like a Scientist" lab activity and a "Your Turn" page at the end of the book support STEM Education and provide young scientists with an opportunity to apply what they've learned in the text. Helpful diagrams and text features, such as a glossary and index, are also included to reinforce content-area literacy and improve close reading.
