Grab Lab Activity



Grab Lab Activity Overview

Have you ever seen a bird catch a worm or a chipmunk stuff their cheeks? How do they do it? Animals have evolved some pretty amazing grabbers and tools over time. In this activity, construct your own Simple Grabber out of TeacherGeek Connector Strips and screws, then design and build it better to be like our feathered and furry friends. Download the Kid's Engineering Challenge document for a quick Build Guide and how to set up Challenges to build grabbers like eagles, robins, monkeys, chipmunks, and even our own human hands!
