This book covers many different types of machinery and all the different aspects of science behind the machines that are made. I think this would be a good book to have for students to be able to access in the classroom because in this time period, technology is extremely popular. This book could be used in a lesson for science as well as used for pleasure reading in any classroom. Students would be engaged with this reading especially those who use different types of technology, for example student who have phones or gaming stations. ( )
