A gentle, sweetly illustrated concept book takes on physical forces as young children learn about pushing and pulling.

It’s time for Bird to build her nest! Follow her as she pulls a worm out of the ground, lifts some twigs that are just the right size, and pushes the twigs into place. Uh-oh! One of the twigs falls to the ground! But after a day of hard work, Bird’s nest is ready and waiting. Can you guess what it’s waiting for? Using simple, clear language and beautiful illustrations, this engaging story is the perfect introduction to physical forces for very young readers. A final spread with some simple questions promotes discussion with parents, teachers, or caregivers and encourages readers to think about the concepts introduced.
