Geraldine and the Rainbow Machine

In the fourth book in the Gizmo Girl series, Geraldine tackles issues of diversity when a new kid joins the class.

Geraldine is an energetic, spirited second-grader with a passion for inventing and she has an all-new invention sure to wow her classmates! Her latest mission is to unite her class in celebration of their unique differences.

When Geraldine sees the kids at recess giving the new kid from Pakistan a hard time for being different, she decides it is time for a new invention to help support her new friend. Sorting through her parents' old gadgets and gizmos, she finds exactly what she needs to create the perfect rainbow machine—designed to show her classmates that while they are different, they also have so much in common.

Enthusiasm and imagination go hand in hand as readers learn that science can be found everywhere, and you can be an inventor by simply using everyday objects. Sol Regwan, the award-winning author of the Gizmo Girl series, hopes young readers will identify with Geraldine as a problem solver, a born leader, and someone they would like to have as a friend.
