Groundhog Day Shadow Experiment: A Hands-On STEM Activity for Kids
Groundhog Day arrives each year with a curious question: will the groundhog see its shadow? This simple tradition opens the door to science, storytelling, and hands-on discovery. A Groundhog Day shadow experiment turns a familiar holiday into a meaningful STEM activity for kids, blending crafting, light exploration, and early physics concepts in a way that feels more like play than a lesson.

This activity combines a paper groundhog puppet craft with a flashlight experiment, creating an interactive way to explore shadows while celebrating Groundhog Day in a kid-friendly format.
What Is Groundhog Day?
Groundhog Day is celebrated on February 2nd and comes from a long-standing tradition tied to weather predictions. According to folklore, if a groundhog emerges from its burrow and sees its shadow, winter weather continues for several more weeks. If no shadow appears, spring-like weather is expected sooner.
While the groundhog does not actually predict the weather, the tradition offers an introduction to talk about light, shadows, and seasonal changes. Kids can celebrate through Groundhog Day crafts, stories, pretend play, and science experiments that explore why shadows appear and how light behaves.
Why This Groundhog Day Activity for Kids Works
A Groundhog Day activity for kids works best when creativity and learning share the spotlight. This Groundhog Day shadow experiment combines fine motor skills, pretend play, and STEM exploration in one engaging setup.
- Encourages curiosity through hands-on science
- Supports early STEM concepts like light and shadow
- Strengthens cutting, gluing, and drawing skills
- Adds storytelling and imaginative play to learning
This STEM activity for kids feels approachable, playful, and adaptable for preschool and early elementary ages.
Supplies Needed for the Groundhog Day Shadow Experiment
- Brown construction paper
- White construction paper
- Scissors
- Glue
- Marker or crayon
- Popsicle stick
- Flashlight
- Clear wall or large sheet of paper
- Play dough (optional)
How to Make the Paper Groundhog Puppet Craft
Start by creating a simple groundhog using basic shapes cut from brown construction paper.
1. Cut out one circle for the head.
2. Cut out one oval for the stomach.
3. Cut out two small half circles for the arms.
4. Cut out two slightly larger half circles for the legs.
5. Cut out two small half circles for the ears.
Arrange the pieces on a flat surface to form a groundhog shape. Glue the oval stomach below the head. Attach the arms to the sides of the body and the legs toward the bottom. Place the ears on top of the head.
Draw a friendly face using a marker or crayon. Cut out two small white rectangles from white construction paper to create teeth. Glue the teeth beneath the mouth for a classic groundhog look.
Once dry, glue the finished groundhog to a popsicle stick. This turns the Groundhog Day craft into a puppet that works perfectly for shadow exploration.
Groundhog Day Shadow Experiment Setup
Dim the lights in the room or move to a space with minimal natural light. Hold the flashlight so it shines toward a blank wall or large sheet of paper. Place the paper groundhog between the flashlight and the wall to create a shadow.
To simplify the experiment and remove variables, squash the play dough into a ball and smush it onto the counter. Stick the popsicle stick in the play dough to hold the groundhog steady. Use this opportunity to explain to kids how reducing variables is part of the scientific process. And by only moving the light, they are doing just that.
This setup introduces the basics of how shadows form. The groundhog blocks the light, creating a dark shape on the surface behind it.
Exploring Shadows Through Play
This Groundhog Day shadow experiment invites observation and discovery through simple changes.
- Move the flashlight closer to the groundhog and notice the shadow grow larger.
- Move the flashlight farther away and watch the shadow shrink.
- Change the angle of the light and observe how the shadow stretches or fades.
- Move the groundhog to different positions to see how shadows shift.
At certain angles, the shadow may nearly disappear. This opens up conversations about how light direction and distance affect shadows. Kids can describe what happens, compare results, and make predictions before each change.
Connecting the Experiment to Groundhog Day
This STEM activity for kids connects directly to the Groundhog Day tradition. The paper groundhog acts out the famous moment of emerging from the ground and encountering light. The flashlight represents sunlight, and the shadow mirrors the folklore shared each February.
Pairing the experiment with a Groundhog Day book or short story adds another layer of meaning. Pretend play can extend the activity, with the groundhog “deciding” what kind of weather might come next based on its shadow.
Ways to Celebrate Groundhog Day With Kids
Groundhog Day offers many opportunities for learning beyond this experiment.
- Create a pretend burrow using cardboard or a paper bag.
- Act out the Groundhog Day story with puppets.
- Track shadow changes at different times of day.
- Compare indoor flashlight shadows with outdoor sunlight shadows.
These simple extensions help Groundhog Day feel special while supporting curiosity and exploration.
A Simple STEM Activity With Light and Shadows
The Groundhog Day shadow experiment blends crafting, pretend play, and science into one meaningful Groundhog Day activity for kids. A paper groundhog, a flashlight, and a darkened area create an inviting setup for exploring light, shadow, and movement through hands-on discovery. This STEM activity for kids supports curiosity, observation, and early science skills while celebrating a beloved seasonal tradition in a playful, creative way that feels memorable long after Groundhog Day ends.
