Children exploring gravity


Get away from the computer screen and join us for some hands-on STEM as you explore our indoor and outdoor exhibits. This event will be rain or shine, so make sure you dress appropriately and bring your umbrella, just in case! 

Events will take place in the Physical Education Center on the Glen Ellyn campus at College of DuPage. Visit our Map and Directions page.

2022 Exhibitors

American Institute of Architects - Northeast Illinois Chapter

In this activity, participants will learn the basics of solar orientation and how structures can be built to help provide shade from the sun. Participants will design and build structures that provide shade. (1) with the black construction paper and (1) with the white construction paper. After the structures have been assembled, participants will place them outside and keep track of how long it will take an ice cube to melt while being underneath their structure. For comparison participants will leave a third "control" ice cube outside of the structure and compare melting times.

American Science and Surplus

Join American Science and Surplus as we demonstrate how to make a cloud in a bottle with this super simple and really cool weather science experiment.


Blinkie is back! Learn how to solder your very own STEMCON blinkie.

COD Chemistry/Chemistry Bonding Club/PPAC

The booth activities will include acid-base neutralization detected by natural dyes and indicators, chromatography with water soluble markers, and polymerization with slime or silly putty.

COD Engineering and Technology Club

NASA needs your help! They need you to get in your rocket ship and travel to the moon to collect special gravel called BP-1, so that they can study it in their labs! Once you get to the moon, your job is to collect your BP-1, travel through all the obstacles, and get back to your spaceship with as much gravel as possible before take off! Can you help NASA out? Students will drive 3D printed rovers, designed by the Engineering and Technology Club, around a track with designed obstacles with the goal of making it to the end with as much gravel as possible.

COD Math Club

Small little brain teasers and puzzles for students to try out. We will also be holding a scavenger hunt at the event. The farther the student gets in the hunt, the harder the problems become. We will have color coded papers representing the difficulty of problems (Red, Yellow, and Green), labeled with suggested grade or suggested color students should choose. Participants will receive an award after completion of scavenger hunt.

COD Natural Areas

College of DuPage - COD Natural Areas is 40 acres of prairie, woodland marsh and other historically native Illinois habitat located on the campus of College of DuPage in Glen Ellyn, Illinois.  The Manager of the areas, Outdoor Lab/Prairie Manager, Remic Ensweiler will lead a tour of areas of these preserves for those interested.  The tour will last 45 minutes to an hour and will be conducted outside so patrons should dress for the weather. No reservation necessary - check in at the COD Natural Areas Prairie Tour booth 15 minutes prior to the tour start time.

Tours offered at 11 a.m., 1 p.m., and 3 p.m.

COD Physics

Numerous hands-on activities showing how the forces of electricity and magnetism are related to the world around us and how they are related to each other.

COD Society of Women Engineers

Make "squeezy" flashlights using an LED, a coin cell battery and adhesive foam while learning the ins-and-outs of electronic circuitry.

COD Student Education Association

Piper Cleaner Tower Activity. Each person will have a certain amount of piper cleaners and will need to balance an Oreo on top.

COD Welding

Learn about different types of welding, including shielded metal arc welding (SMAW), flux-cored arc welding (FCAW) and gas tungsten arc welding (GTAW), and their differences and uses.

DuPage Children's Museum

Explore backyard ecology by making observations of the natural world around you. Create a garden in a glove to take home and find out what it takes for a seed to germinate.

DuPage Regional Office of Education STEM Team

We will have 3 different activities where participants can launch items such as marshmallows and participant-made "rockets." The participants will utilize basic problem solving and engineering processes for building, testing and modifying their launchers to get optimal results.

Forest Preserve District of DuPage County

Explore how the Forest Preserve District of DuPage County is helping freshwater mussels- one of the most imperiled groups of animals in North America- through propagation and conservation efforts. Examine freshwater mussel specimens plus the equipment engineered to raise them and use a microscope to count glochidia just like a freshwater mussel ecologist. 

Girl Scouts of Greater Chicago & Northwest Indiana

Straw Airplane - How far will your airplane fly using nothing more than construction paper and straws?

Glen Ellyn Public Library

DIY Catapult. Build your own catapult and learn the science behind this simple machine.

Illinois Simpson Archaeology

Explore the wonders of archaeology at this exhibit, with various stations showcasing stones, bones, artifacts, and simulations.

Mathnasium of Glen Ellyn

Using a set of cards based on the binary number system, I can read your mind and guess what number you are thinking of. STEM Connection: Even if a process looks like magic, we can figure out how it works by looking for patterns, asking questions, and making connections.

Naperville Astronomical Association

Viewing the Sun through telescopes (clouds permitting), both white light filter (full spectrum) and hydrogen alpha. This activity is weather dependent.

Nicor Gas

We are planning to conduct a natural gas pipeline fusing demonstration where we will actually connect segments of pipeline together and showing posters/photos of natural gas flares which enable us to release gas from retired lines and avoid emitting greenhouse gas!

Northern Illinois Rocketry Association

Since 1963, the Northern Illinois Rocketry Association (NIRA) has been bringing together rocket hobbyists from all over the greater Chicago area. Our booth will include a display of some of our rockets, and if the weather allows, we will also launch some rockets! Launches will take place in the practice field east of the tennis courts. Follow the sidewalk signs to get to the viewing area, just a short walk from the main tent! This activity is weather dependent.

Rockets launch at 11 a.m., 1 p.m., and 3 p.m.

Purple Me Green, the Science Store

Science Station Fun. 4 different stations of hands on STEM Fun. Engineering, logic games, Pool O Matter, and Nature exploration. The truck will also be on site with even more fun activities and selections from the store.

Swift Nature Camp

Meet "Bubba" the pig and learn about nature, earth science and the environment.

TechGirlz, CITF

We will be bringing a few Edison Robots with some code for the students to play and tinker with.

The Morton Arboretum

Trees Up Close- Take a closer look at tree parts and their function

The Conservation Foundation - Youth Programs

This year, we will be highlighting the theme of one of our summer camps: Animal Architects! We will showcase the amazing structures animals create to survive and thrive in our area and challenge you to consider how YOU would build YOUR home if you could only use what you found outside! Creativity is encouraged!

University of St. Francis - STEM Educator Program

In this activity, we'll try to fit the fewest number of squares in a rectangle.  There are some neat observations we can make from this, and you have a chance to draw a near perfect logarithmic spiral after completing the activity!
