Your child may have learned in science class that birds can fly due to their hollow, lightweight bones, but it's hard to understand how hollow bones can be strong enough to support a bird's muscles. In this science activity, you and your child will see just how strong a hollow structure can be by testing how many pennies a structure supported by hollow paper "bones" can hold. The answer may surprise you!
As she completes this experiment, your child will learn about the strength of hollow structures and will learn that in science (as in life), things aren't always as they seem.
