Shadow Science Activity Groundhog Day
Make your own groundhog and learn about light and shadow with this fun family craft activity. Watch the video for materials and instructions.
Every February 2nd, a groundhog named Punxsutawney Phil emerges from his burrow in search of his shadow. The view of his shadow predicts whether winter will be prolonged or cut short for an early spring.
Shadow is the absence of light. Light is a form of energy that travels in a straight line until it hits an object. If the object blocks the light from passing through it, that creates an area of darkness – a shadow- on the other side. The angle at which light strikes an object also affects the size and shape of its shadow. An object blocks more light when the light is at a lower angle (side-on), making long shadows; when the light source is at a higher angle (overhead), the shadows are shorter. You can see this for yourself using a flashlight and creating different types of shadows for your Groundhog.
