One of our goals around here is to create lessons that can be adapted for a variety of ages, abilities and interests. With that in mind I’ve gathered up a number of different activities and resources so you can pick and choose what will work best for your Marshmallow loving students. Some of these activities can be used as young as preschool, while others are best suited to middle grade students. Use common sense, you know your students and children the best.

Getting Started – Marshmallow Tinkering

What is the best way to start exploring marshmallows? Let kids play! Simply set out a variety of items like marshmallows of various shapes, sizes and colours, skewers, toothpicks, candy decorating pens, magnifying glasses or even a microscope, knives or scissors, and more. Let the kids get hands-on and learn. It doesn’t matter if they want to be scientists, engineers or artists, however they want to explore the marshmallows is fine. The more excited they are about learning, the more they will learn.

Tip! For little guys a set of playdough knives and scissors works perfectly and are much safer for small fingers.

Here are some items we include in a marshmallow exploration centre:


Now on to some ideas for building your Marshmallow Unit Study, play centre or STEM Project.
