This nonfiction book is all about measuring weight. The books starts out explaining weight and measuring weight. The author then explains about the weight of vehicles and then starts comparing weights of vehicles. The book compares vehicles such as, toy scooters to mountain bikes, mountain bikes to snowmobiles, snowmobiles to cars and so forth each getting heavier. Each comparison is on facing pages with a photograph of the vehicle and measuring scales showing the comparison. The book has great photos, nice additional information bubbles and a measuring activity students can do. There is also a heavy quiz and facts page at the end of the book, along with a glossary, find out more and index. Upon seeing this book, I thought boring! When I actually started reading it, I really liked it not finding it boring at all. Young elementary boys will like it and teachers will find it useful when teaching measuring and weighing.
