Rat Basketball: The Away Game

Yep, real rats! COSI’s famous Rat Basketball hits the road in this one-of-a-kind outreach workshop exploring the science of psychology! How can a rodent with a penny-sized brain learn to play basketball? Better yet, why would we teach an animal a behavior so opposed to its nature? In this hands-on program, you’ll explore behavior conditioning and see its strength as you test positive reinforcement on your classmates. Then, you’ll cheer on the rats as they compete in a one-on-one lightning round showdown!

Superhero Science

It’s a bird! It’s a plane! Nah, it’s super-science! Backed by a team of comic book heroes, you’ll use science to bring “impossible” super powers to life! Explore “levitation” by manipulating air pressure, explore potential and kinetic energy, use the states of matter to create flight, and learn the ingredients of a cloud by making real clouds right in the classroom! Pass Hero Training and you’ll get a chance to touch COSI’s famous Electrostatic Generator to see (and feel!) the shocking power of electricity at work! You can keep the city safe with science on your side!

  • Grade Level: Grades 1-8

Beginner Robotics

What is a robot? How does it work? There’s one way to find out. In this incredible introductory workshop, you’ll explore energy, circuitry, and the “language” robots speak: programming! Then, you’ll take control of your own hand-held Bee-Bot and test out COSI’s customized challenges that connect to grade-level literature, science, and mathematics standards! Write a fairytale and bring it to life through programming, pollinate flowers, explore community resources, and so much more. There’s no limit to the work robots can do, and you’ll try it all.

  • Grade Level: Grades 1-4

Animal Adventures

NEW! Bring the science of living things to your classroom in this interactive ecological adventure. First, you’ll meet and touch some of COSI’s live animals to explore their adaptations, diets, and habitats. Then, you’ll touch real animal furs, piece together life cycle puzzles, and build a habitat around a living reptile. With a dichotomous key and video microscope, you’ll inspect real arthropods to decide “Is it a bug?” and explore the science of animal tracking by getting up close and personal with animal tracks… and the scat they leave behind!

  • Grade Level: Grades 3-8

Astronomy Academy

NEW! Discover the foundations of astronomy in this out-of-this-world outreach workshop. First, we’ll explore our stellar neighborhood – our solar system – and construct a classroom-sized model of the relative size and distance of the planets. Then, we’ll examine air pressure and explore how your weight and even your age might be different on another planet! Finally, you’ll put teamwork to the test with engineering challenges by building a free-standing moon base from simple materials and designing, building, testing, and redesigning air-powered rockets.

  • Grade Level: Grades 5-8


NEW! The excitement of engineering, force and motion, and mechanics hits the road in this energizing hands-on workshop. We’ll explore energy – at work in the world around us – and how it flows through conductors. You’ll dream it and build it with awe-inspiring Blue Blocks and construct magnetic marble-run roller coasters; program real robots, construct circuits to make music, and even design, build, test, and redesign to create a recycled floating contraption in our five-foot-tall wind tube!

  • Grade Level: Grades 1-6

Gross Science: Bodyworks

NEW! In this brand new, totally engrossing workshop, you’ll get hands-on with the surprising science of the human body. We’ll start small – really small­ – by examining the mighty power of microorganisms and building a bloodstream right in your classroom. Then, you’ll sort organ sizes, compare and contrast healthy and broken bones with real human X-rays, measure yourself against record-holding humans, and make your own sticky, slimy snot to see how this gross product has a very important job to do!

  • Grade Level: Grades 1-4

Coaster Creators

Hold on tight! This open inquiry, engineering design workshop is filled with ups and downs as you explore the engineering process, communication, and collaboration. First, put the force of gravity (and teamwork) to the test in a wild marble challenge. Then, scream ahead as you build your own roller coaster around chairs, through desks, and across chalkboards. With limitless flexible track, supports, and marbles, if you can dream it, you can design it, build it, test it, and redesign it until your coaster is ready to thrill.
  • Grade Level: Grades 3-12

In Depth Dissection: Cow Eye

Diagrams can only take you so far. To really understand what’s going on inside of the eye, you’ve got to see it for yourself. In this engaging and eye-opening classroom program, you’ll explore the complex structure and function of a cow’s eye to examine how it relates to our own. Surprising, scientific, and sometimes slimy, this gripping view of the inner eye may leave you seeing things differently.
  • Grade Level: Grades 9-12

In Depth Dissection: Sheep Brain

Your thoughts, memories, skills, personality, senses… Your brain is you. In this hands-on program, you’ll explore the function of the brain by testing your brain’s processing power and its division of labor – your lobes and hemispheres – in unforgettable exercises and illusions. Then, your team will dissect a real sheep brain to examine how structure and function unite to create you – everything about who you are – in three pounds of flesh.
