    Easter Toothpick Structures STEM Challenge

    Modified: Apr 4, 2025 · Published: Apr 6, 2022 by Emma Vanstone · This post may contain affiliate links · Leave a Comment

    Toothpick structures are a fantastic, low-cost, and easy STEM challenge that keeps kids busy for hours. We used cocktail sticks, but you could also use straws or spaghetti.

    I set the children a challenge to build a structure that would hold a chocolate egg off the ground.

    How to build a toothpick structure

    There are no instructions for this one, apart from building a structure that:

    • Stands up with no extra support.
    • Only use the materials above.
    • Can hold a small chocolate egg without falling over.

    Don’t be limited by our rules, though, you can make your own.

    These are the structures my children built. What do you think?

    We then tested to see if our structures could hold chicks and rabbits. Since these were lighter, it wasn’t much of a problem.

    Things to think about – building a strong toothpick structure

    Shapes are a good thing to consider when building toothpick structures like this. We found a square shape with extra support in the form of triangles, which made a stronger structure.

    Triangles, arches and domes are all strong shapes are used by engineers to make structures strong. Next time you see a bridge, count how many different shapes you can see.

    Imagine a square made from straws. If you push down, it will fold down on itself, but a triangle won’t collapse unless one of its sides breaks. Any force applied to a triangle is evenly distributed from the vertex to the base. This means triangles are much stronger than squares.

    Extension ideas

    Can you build a tower that is at least 10cm high? Or 20 cm high?

    How about a tower that can hold three chocolate eggs?

    Can you build the chicks a new house? We used blueberries for this one.
