Each COSI Connects Water Kit is filled with engaging, hands-on STEAM activities. COSI’s education experts have created these activities to encourage inquiry-driven learning and reinforce Ohio's Learning standards.

Float Your Boat - Which objects float in water, and which objects sink? Try experimenting with different objects to see which ones will float. Kit includes activity instructions and objects of various weights, sizes, and shapes, including a paperclip, pen, tin foil, tissue paper, and a penny.

Nature’s Zoom Lens - Can you use water to magnify an image? Try it out! Kit includes activity instructions, zipping plastic bag, paper slip with tiny writing, microscope slide, and pipette.

Surface Tension - How many drops of water fit on a penny before it will spill over? 10? 25? More? Perform your own surface tension test to find out. Can you use what you learned about surface tension to make a paperclip float? Kit includes activity instructions, penny, paperclip, tissue paper, and pipette.

Chromatography Flowers - Scientists use a process called chromatography to learn about different substances present in a mixture. You can do chromatography at home with water to explore different pigments hidden inside markers! Kit includes activity instructions, coffee filters, disposable cup, dark colored markers, and pipe cleaners.

School of Fish - Learn the difference between a school and a shoal of fish. Then, make your own model shoal of fish that “swims” with the help of surface tension! Kit includes activity instructions, craft foam, scissors, cotton swab, and dish soap.
