Rosie Revere dreams of one day becoming a great engineer. Shy and uncertain of her ability, she hides the gadgets and gizmos she’s made in her attic or under her bed. Afraid to fail and be laughed at, Rosie is hesitant to share her amazing ideas. Great-Great-Aunt Rose helps her to see each fail as one step closer to making her inventions a success. Some of the activities you will find in this unit are building a snack tower and doing an egg drop experiment.
