Air and water are found all around us. Readers will see how fun it is to work with them in this step-by-step instructional guide to experiments with air and water! Readers are treated to a lesson in the properties of each substance, then asked to apply their knowledge through fun, hands-on experiments. Each experiment comes with detailed, numbered instructions and photos, and a question-and-answer feature on each spread answers questions that may arise as readers move along in the process. A concluding quiz tests readers’ ability to think critically about the essential concepts covered in the text.
