"These books are excellent sources of bilingual expository text for young students. They explain in full detail how to make the product. Each bilingual book also shows photos of materials needed to complete the project. The procedural text is presented in small chunks explaining every step. Colorful photographs of children carrying out the task add to the text. Internet sites included are added resources for students and teachers. Both books are excellent sources for English and Spanish science fairs. The Spanish translation is well written and taken directly from the English version."
