关于此电子书
What are different types of soil made of, and just how is dirt made? In this title, students will get the opportunity to conduct experiments that will help them learn all they ever wanted to know about dirt! Kids will also get the chance to investigate what types of things live in dirt, and they will even get to make their own compost! Using everyday items that kids can easily find around the house, young students will turn into scientists as they carry out step-by-step experiments to answer intriguing questions. Along the way, children will learn important science skills as they investigate dirt and soil, record their observations, and draw conclusions.
Dirt includes seven experiments with detailed, age-appropriate instructions, great facts and background information, a “Conclusions” section to pull all the concepts in the book together, and a glossary of science words.
