The Culture World Science series teach kids about different environments and topics. A truly hands-on education product, kids print the pages, look at photos of other kids assembling the diorama, then cut on the red lines, fold on the green lines to build their own. Culture World: The Solar System teaches kids about outer space on the computer. Photographs from NASA and the Hubble telescope were used to give the diorama the most realistic images possible.
