I would put the age group for this book at pre-school through 2nd grade. Educator reviewed prrojects based on favorite childhood themes. Projects tested with children, can be completed in short space of time, good step-by-step photos and drawings, and easy to follow directions. Each project has a complete list of materials needed and all materials are inexpensivee and commonly found around the home.
Sampling of projects: A rocket ship to fly; recipe for Planet Popsicles; shiny robots; shooting star painting; paper plate flying saucers; and several more.
