Spaghetti and Marshmallow Towers

October 17th, 2026

In this workshop, participants will be split into even teams. They will be given marshmallows and uncooked spaghetti in order to build the tallest tower possible! Through this fun activity, they will learn the engineering design process as well as how to collaborate with others.

Eggshell Chalk

November 14th, 2026

What has the same key ingredient as the fun chalk that you use to draw on the sidewalk? Eggshells! In this experiment, we are teaching attendees how to repurpose their old eggshells to make an eco-friendly chalk. They will be able to make their own and bring it home to try out!

Penny Boat Experiment

December 5th, 2026

In an engineering-style workshop, we will be giving participants each tin-foil and pennies. Within a limited amount of time, they will be encouraged to design a tin-foil boat to hold as many pennies as they can when placed in water! In addition to using a hands on activity to learn about the engineering design process, we will also be teaching kids about density in relation to water.
