Origami Firefly Paper Circuits

I love fireflies! We don’t see them around where I live, but I have fond memories of them from my childhood. I wanted to share those memories—and the science behind them—with my kids, and this project was the perfect way to do it.  So, today, I’m showing you how to make Origami Firefly Paper Circuits, a hands-on STEAM activity that combines art, electricity, and biology in one fun project!

Learning About Fireflies

This activity is inspired by the charming and educational picture book How to Survive as a Firefly by Kristen Foote. It’s a playful yet fact-filled introduction to the life cycle of fireflies, filled with quirky humor and engaging illustrations.

Before diving into the craft, I recommend reading this book aloud to explore topics like:

• Firefly metamorphosis

• Bioluminescence (the way fireflies light up)

• Insect anatomy

• Habitat and behavior

In fact, you can even extend this into a mini science lesson by discussing what causes a firefly’s glow (spoiler: it’s a chemical reaction called luciferin oxidation inside the insect’s abdomen!).

Supplies for the Origami Firefly Paper Circuits

Origami Supplies:

• One square piece of paper (trim an 8.5”x11” sheet to a square)

• Markers or crayons (optional, for decorating)

Paper Circuit Supplies:

• 1/4″ adhesive copper tape

• 5 MM or 10 mm LED lights (any color, though yellow mimics real fireflies)

• 3V lithium coin cell battery (like CR2032)

• Clear tape or glue (minimal)

You can find all of these supplies easily online or in STEM kits for kids.

Step-by-Step: How to Make an Origami Firefly

1. Fold Your Paper
   Begin with a square piece of paper. Fold it in half diagonally to create a triangle.

2. Form the Wings
   Fold the left and right corners of the triangle down to meet the bottom point. These become the firefly’s wings.

3. Make the Head and Body
   Flip the paper over. Fold down the top corner, then fold it back up partway to create a small triangular flap—this becomes the head. Fold in the left and right edges slightly at an angle to narrow the body shape.

4. Flip it Over
   When you turn it back over, you’ll see your firefly shape with wings, body, and head complete!

How to Add the Paper Circuit

Now for the fun part—the light-up circuitry!

If you’ve never tried a paper circuit before, don’t worry—this is a beginner-friendly way to learn!

Step-by-Step Paper Circuit Instructions:

1. Attach Copper Tape
   Lift one wing and run a strip of copper tape from the wingtip to the center of the body. This is your positive side.

2. Add Second Tape Path
   On the underside of the opposite wing, place a second strip of copper tape, leaving a small gap between the two paths. This one will touch the battery when the wing is folded closed.

3. Position the LED
   Identify the positive (longer) and negative (shorter) legs of the LED. Tape the LED in place with the long leg connected to the positive tape line.

4. Place the Battery
   Tape the battery into the center with the positive (+) side facing down. Ensure that the copper tape touches both sides of the battery when the wing is closed.

5. Test It!
   When you press the wing down gently, the circuit should close and the LED will glow—just like a real firefly!

STEAM Educational Tie-Ins for the Origami Firefly Paper Circuits

This firefly paper circuit project supports cross-curricular learning. Here’s how:

Science: Learn about fireflies, circuits, and bioluminescence
Technology/Engineering: Explore how simple circuits work
Art: Practice origami folding and visual design
Literacy: Pair with a great read-aloud and follow-up writing or drawing activity

Additionally, this makes a great addition to a summer nature unit, an insect study, or a glow-in-the-dark themed week.

The Origami Firefly Paper Circuit is a magical way to blend creativity and science. Whether you’re teaching at home or in a classroom, this is a memorable lesson that lights up learning—literally!
