Water molecules are amazing—and so is just plain water! In this book, young scientists investigate how water droplets can magnify, the magic of surface tension, and the effects of adding salt to water when potatoes are in it! Each of the 10 projects includes a Background section to explain the science topic at work, materials, clear step-by-step instructions, and an Observations section helping young scientists understand what they’ve done. Several projects include science fair ideas and expanded versions of the experiment to engage readers further. A discussion of the scientific method and helpful glossary conclude the book.
