Don’t eat that Halloween candy – Use it for science!

Candy is great… especially when it’s used for science! As Halloween approaches, here’s a look back at some of the ways iSchool has used candy in its STEAM SEL activities.  Want these types of memorable experiences for your children? Register now for our Winter Break Camp.


Geodesic Dome: We used 11 gumdrops and 25 toothpicks to build mini Geodesic Domes.

Structural Engineering: We use marshmallows and spaghetti to examine the structural integrity of triangles versus squares. Then, we build strong bridges and buildings.

Solutions and Experimental Variables: We used gummy bears in an experiment with a control and variables. We test different colors of gummy bears to see how they would hold up under various conditions: baking soda mixed with water, vinegar mixed with water, salt water, and sugar water. Each test also had control bears in water and air. We observed them over time to see how they changed.


Building Blind: This is one of our exclusive STEAM SEL activities. Children sit back to back and give each other directions to build a structure out of candy. The learn ways to improve communication and listening skills.


Candy DNA: We used Twizzlers, toothpicks, and gummy bears to make a double helix.  Even our youngest campers were able to understand the concept of matching base pairs, and when colors didn’t match, they called them “mutations”!

Earthquake-Proof Structures: We challenged students to build the tallest a structure and test it on our home-made shake table. Then, we challenged them to show empathy and improve the structure!


Marshmallow Catapults: We used Popsicle Sticks, rubber bands, and a spoon to build a simple catapult capable of flinging marshmallows across the room. We also made targets on the floor to learn about and improve accuracy and precision.


Candy Patience Game: Modeled on the Stanford Marshmallow Experiment, we gave students the option of eating one piece of candy now, or waiting to earn more pieces. Every child waited! Along the way we discussed ways to be patient and self-regulate.


Jellybeans and our Senses: We pinched our noses while eating jellybeans and tried to guess the flavor. It was pretty hard! We learned that a large part of our sense of taste comes from our sense of smell.


The Marshmallow Challenge: We do the some variation of the Marshmallow Challenge in every camp. We challenge children to work in teams and be open-minded, patient, and creative as they build a tower out of marshmallows, spaghetti, and tape.
