I have used several of the Make it Work books when I homeschooled my children. I am now going thru the lists and trying to evaluate these books and determine the age level that would be appropriate for each book. This book spans some simple projects to some very involved modeling projects. Since I have seen some much more usable project books on dinosaurs that you put together as a skeleton or cut out pieces and them assemble that have much better graphics than I could produce, I will have to say that unless my students have a much better grasp of the artistic I will settle for the easy way out.
