Whelmers
What is a Whelmer?
Everyone likes to watch a fireworks show. That large bang and colorful flash of light certainly can capture our attention. A cluster of exploding sky rockets can be exciting, if not overwhelming. Scientists find similar excitement in learning new concepts and techniques—their curiosity can be captured by a new scientific experience.

These activities are designed to capture your curiosity and engage you in the scientific thinking process; while having fun! They are based on classic scientific discoveries; some dating back over 200 years. Scientists have used these activities to engage audiences around the world. They might not overwhelm you, but we predict you just might be whelmed!
