Activities
Waves of Wonder programming features special activities provided by the Museum and community partners, including:
Rain garden tours: Have you ever been interested in creating a native garden at your home? Join a Museum Natural Areas Manager on a guided walk through our native rain gardens. You’ll learn about the importance of these spaces and discuss how to build your own! Free seed packets will be available while supplies last.
Ohio Department of Natural Resources: When driving around Cleveland, you may have noticed signs that state what watershed you’re entering. What is a watershed, and why is it important? Explore an interactive watershed model and learn how land use impacts water quality.
Cleveland Metroparks: Lake Erie has only 5% of the water out of the Great Lakes, but boasts 50% of the fish population. How can we work to keep water safe for Lake Erie animals? Meet a Metroparks Naturalist and play a tabletop game about the water cycle. As you adventure through the game, you’ll thread together a bracelet with your unique water journey!
Great Lakes Science Center: There are many ways that scientists test water quality. One of these includes pH, the measurement of acidity. Discover what acidic water means for Lake Erie and why it can be a problem.
Community craft in Smead Discovery Center—Presented by PNC: How do you practice sustainability? Make your mark by describing your habits on our craft wall. Marvel at the impact that many individual efforts can make when added up among a community.
Water quality testing: To ensure that water is safe and healthy, scientists must use many different tools. Take part in an interactive demonstration with a Museum Educator to test the quality of different streams around Cleveland.
Lorain Metroparks: Lake Erie attracts an incredible number of species of waterbirds at all times of the year. Meet an ornithologist to explore their role in the ecosystem while observing bird artifacts up close.
Collinwood Painted Rain Barrel Project: Rain barrels can greatly reduce harmful runoff and provide a free clean water source for gardens. Watch a local artist from Zolten Wood Design paint a beautiful rain barrel as you draw designs for your future rain barrel.
