Balancing Weights and Measurements

In this video, Eddie, Abby, and Luke explore the concept of balancing and weight through a series of fun experiments. They start by discussing how a mobile is similar to scales, then compare the weights of a cube and a rectangular prism. The children conduct experiments to see how many cubes equal the weight of an apple. Finally, they imagine weighing large animals like elephants and dinosaurs, learning that the Argentinosaurus was much heavier than an elephant.
